METHODS Between Ja...AIM To compare the Glasgow-Blatchford score(GBS), Rockall score(RS) and Baylor bleeding score(BBS) in predicting clinical outcomes and need for interventions in patients with bleeding peptic ulcers. METHODS Between January 2008 and December 2013, 1012consecutive patients admitted with peptic ulcer bleeding(PUB) were prospectively followed. The pre-endoscopic RS, BBS and GBS, as well as the post-endoscopic diagnostic scores(RS and BBS) were calculated for all patients according to their urgent upper endoscopy findings. Area under the receiver-operating characteristics(AUROC) curves were calculated for the prediction of lethal outcome, rebleeding, needs for blood transfusion and/or surgical intervention, and the optimal cutoff values were evaluated.RESULTS PUB accounted for 41.9% of all upper gastrointestinal tract bleeding, 5.2% patients died and 5.4% patients underwent surgery. By comparing the AUROC curves of the aforementioned pre-endoscopic scores, the RS best predicted lethal outcome(AUROC 0.82 vs 0.67 vs0.63, respectively), but the GBS best predicted need for hospital-based intervention or 30-d mortality(AUROC0.84 vs 0.57 vs 0.64), rebleeding(AUROC 0.75 vs 0.61 vs 0.53), need for blood transfusion(AUROC 0.83 vs0.63 vs 0.58) and surgical intervention(0.82 vs 0.63 vs 0.52) The post-endoscopic RS was also better than the post-endoscopic BBS in predicting lethal outcome(AUROC 0.82 vs 0.69, respectively).CONCLUSION The RS is the best predictor of mortality and the GBS is the best predictor of rebleeding, need for blood transfusion and/or surgical intervention in patients with PUB. There is no one 'perfect score' and we suggest that these two tests be used concomitantly.展开更多

METHODS: In our prospective study, 60 consecutive elderly patients with upper gastrointestinal bleeding from a peptic ulceration(cases) and 60 matched patients with a non-bleeding peptic ulcer(controls) underwent small bowel capsule endoscopy, after a negative colonoscopy(compulsory in our institution). Controls were evaluated for non-bleeding indications. Known or suspected chronic inflammatory conditions and medication that could harm the gut were excluded. During capsule endoscopy, small bowel ulcerative lesions were counted thoroughly and classified according to Graham classification. Other small bowellesions were also recorded. Peptic ulcer bleeding was controlled endoscopically, when adequate, proton pump inhibitors were started in both cases and controls, and Helicobacter pylori eradicated whenever present. Both cases and controls were followed up for a year. In case of bleeding recurrence upper gastrointestinal endoscopy was repeated and whenever it remained unexplained it was followed by repeat colonoscopy and capsule endoscopy.RESULTS: Forty(67%) cases and 18(30%) controls presented small bowel erosions(P = 0.0001), while 22(37%) cases and 4(8%) controls presented small bowel ulcers(P < 0.0001). Among non-steroidal antiinflammatory drug(NSAID) consumers, 39(95%) cases and 17(33%) controls presented small bowel erosions(P < 0.0001), while 22(55%) cases and 4(10%) controls presented small bowel ulcers(P < 0.0001). Small bowel ulcerative lesions were infrequent among patients not consuming NSAIDs. Mean entry hemoglobin was 9.3(SD = 1.4) g/d L in cases with small bowel ulcerative lesions and 10.5(SD = 1.3) g/dL in those without(P = 0.002). Cases with small bowel ulcers necessitate more units of packed red blood cells. During their hospitalization, 6(27%) cases with small bowel ulcers presented bleeding recurrence most possibly attributed to small bowel ulcers, nevertheless 30-d mortality was zero. Presence of chronic obstructive lung disease and diabetes was related with unexplained recurrence of hemorrhage in logistic regression analysis, while absence of small bowel ulcers was protective(relative risk 0.13, P = 0.05).CONCLUSION: Among NSAID consumers, more bleeders than non-bleeders with peptic ulcers present small bowel ulcers; lesions related to more severe bleeding and unexplained episodes of bleeding recurrence.展开更多

METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the differencewas compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups(70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8(8.2%) vs 15(21.7%), P < 0.05; 65(66.3%) vs 13(18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant(P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients in the continuing group, and the risk of death and developing acute cardiovascular disease was higher in patients in the discontinuing group(log-rank test, P = 0.000 for both). Furthermore, COX regression multivariate analysis revealed that the hazard ratio(HR) for recurrent bleeding was 2.986(95%CI: 067-8.356, P = 0.015) in the continuing group, while HR for death or acute cardiovascular disease was 5.216(95%CI: 1.035-26.278, P = 0.028).CONCLUSION After the occurrence of peptic ulcer bleeding, continuing antithrombotics increases the risk of recurrent bleeding events, while discontinuing antithrombotics would increase the risk of death and developing cardiovascular disease. This suggests that clinicians should comprehensively consider the use of antithrombotics after peptic ulcer bleeding.展开更多

METHODS: This study retrospectively evaluated the out- and inpatients who underwent endoscopy between 2002 to 2008. The subjects were patients presenting with peptic ulcer bleeding. The details of these patients were obtained from their endoscopic reports and medical records. RESULTS: The rates of Helicobacter pylori (H. pylori ) infection were significantly low (P = 0.039), while the proportion of nonsteroidal antiinflammatory drugs (NSAIDs) users and vascular disease significantly increased over the period studied (P = 0.034 and P = 0.04, respectively). However, there was no significant difference in the proportion of low-dose aspirin users (P = 0.832).CONCLUSION: It's found that the primary cause of peptic ulcer bleeding changed from H. pylori infection to use of NSAIDs over the 7-year period of study. It seems that the number of low-dose aspirin users has increased with the increase in the proportion of vascular disease. It is necessary to take measures to prevent peptic ulcer bleeding among NSAIDs and low dose aspirin users.展开更多

Conventional invasive tests are less sensitive than non-invasive tests in diagnosing H pylori infection in patients with bleeding peptic ulcers. Polymerase chain reaction is a sensitive and accurate method for diagnosing H pylori infection. The aim of this study was to evaluate the diagnostic role of mucosai polymerase chain reaction for H pylori infection in patients with bleeding peptic ulcers. METHODS: In patients with bleeding, non-bleeding peptic ulcers and chronic gastritis, we checked rapid urease test, histology, bacterial culture and mucosai polymerase chain reaction fordetecting H pylori infection. Positive H pylori infection was defined as positive culture or both a positive histology and a positive rapid urease test. For mucosai polymerase chain reaction of H pylori, we checked vacA (s1a, s1b, s1c, s2, m1, m1T, m2), iceA1, iceA2. and cag A. RESULTS: Between October 2000 and April 2002,88 patients with bleeding peptic ulcers (males/females: 60/28, gastric ulcers/duodenal ulcers: 55/33), 81 patients with non-bleeding peptic ulcers (males/females: 54/27, gastric ulcers/duodenal ulcers: 45/36) and 37 patients with chronic gastritis (males/ females: 24/13) were enrolled in this study. In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, 45 patients (51%), 71 patients (88%) and 20 patients (54%) respectively were found to have positive H pylori infection (P<0.001). In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, polymerase chain reaction for H pylori infection was positive in 54 patients (61%), 70 patients (86%) and 20 patients (54%) respectively (P<0.001). The sensitivity, positive predictive value and diagnostic accuracy of mucosai polymerase reaction for H pylori infection were significantly lower in patients with bleeding peptic ulcers (84%, 79% and 81%) than in patients with non-bleeding peptic ulcers (99%, 99% and 98%) (P<0.001, P<0.01 and P<0.001 respectively). The sensitivity, negative predictive value and diagnostic accuracy of mucosal polymerase reaction for H py/ori were significantly lower in patients with bleeding peptic ulcers (84%, 83% and 81%) than in patients with chronic gastritis (100%, 100% and 100%) (P= 0.02, P= 0.02 and P=0.001). CONCLUSION: Mucosal polymerase chain reaction for detecting H pylori infection is not reliable in patients with bleeding peptic ulcers.展开更多

METHODS: From April to September 2002, H pylori status in 60 patients who consecutively presented with gastroduodenal ulcer bleeding was examined by rapid urease tests (RUT), histology, culture, PCR, serology and urea breath tests (UBT). RESULTS: The sensitivity of PCR was significantly higher than that of RUT, histology and culture (91% vs 66%, 43% and 37%, respectively; P = 0.01, <0.001, <0.001, respectively), but similar to that of serology (94%) and UBT (94%). Additionally, PCR exhibited a greater specificity than serology (100% vs 65%, P<0.01). However, the specificity of PCR did not differ from that of other tests. Further analysis revealed significant differences in the sensitivities of RUT, culture, histology and PCR between the patients with and those without blood in the stomach (P<0.01, P= 0.09, P<0.05, and P<0.05, respectively). CONCLUSION: PCR is the most accurate method among the biopsy-based tests to detect H pylori infection in patients with bleeding peptic ulcers. Blood may reduce the sensitivities of all biopsy-based tests.展开更多

In 144 patients the ulcers showed a clean base, and in 46 the ulcers showed fiat spots and in 21 old adherent clots. The endpoints were re-bleeding, surgery, hospital stay, blood transfusion and death. After discharge, re-bleeding and death were reevaluated within 30 d.RESULTS: The study groups were similar with respect to baseline characteristics. Re-bleeding was recorded in 5 patients of Group 1 and in 4 patients of Group 2 (P = 0.879). Three patients in Group 1 and 2 in Group 2 underwent surgery (P = 0.773). The mean length of hospital stay was 4.6 ± 1.6 d in Group 1 vs 4.5 ± 2.6 d in Group 2 (P = 0.710); the mean amounts of blood transfusion were 1.9 ±1.1 units in Group 1 vs 2.1 ±1.7 units in Group 2 (P = 0.350). Four patients, two in each group died (P = 0.981). After discharge, a new bleeding occurred in 2 patients of Group 1 and in 1 patient of Group 2, and one patient from Group 1 died.CONCLUSION: We demonstrate that the effect of oral omeprazole is as effective as intravenous therapy in terms of re-bleeding, surgery, transfusion requirements, hospitalization and mortality in patients with bleeding ulcers with low risk stigmata. These patients can be treated effectively with oral omeprazole.展开更多

The nursing risk management and conventional nursing management were implemented for the two groups, respectively. The success rate of hemostasis, average length of stay, cure rate, complication rate, dyspnea rate, nursing dispute rate, SAS score, and SDS score were compared between the two groups. Patients’ satisfaction with nursing quality was also compared. <strong>Results:</strong> After the implementation of two different nursing management methods, all the above-mentioned metrics were better in the observation group than in the control group, and the differences were statistically significant (P < 0.01 or P < 0.05). <strong>Conclusion:</strong> The application of nursing risk management in the nursing intervention process of patients with severe peptic ulcer bleeding can effectively reduce the probability of nursing risk events, increase the cure rate, shorten the patient’s hospital stay, but also improve the patients’ psychological state and increase the patient’s satisfaction with nursing quality, which is worth clinical promotion.展开更多

Pe...Acute upper gastrointestinal bleeding (UGIB) remains an important emergency situation. In the last two decades, major developments took place influencing incidence, etiology and outcome of patients with acute UGIB. Peptic ulcer bleeding is the most significant complication of ulcer disease being responsible for 50% of all cases mortality. Aim of the study: To compare between endoscopic clip application versus argon plasma coagulation in management of bleeding peptic ulcer (BPU). Patients and Methods: Sixty patients suffering from acute UGIB were randomly divided into two groups: group I included 30 patients treated with endoscopic clip application and Group II included 30 patients subjected to endoscopic APC. All patients were classified according to Forrest classification and the clinical Rockall score. Results: There were significant differences between the two groups as regard Forrest classification (P 0.05). Re bleeding was significant with higher Rockall score in group I (P 0.05). Conclusion: Endoscopic application of hemoclips have a less re bleeding rate than Argon plasma coagulation for treatment of bleeding peptic ulcer, although this was statistically insignificant, meanwhile APC is still less cost and easy. Clinical and endoscopic assessment (through Rokcall score and Forrest classification) could help in making best choice for endoscopic management.展开更多

This study compared the effectiveness of TAE and surgery in patients with peptic ulcer bleeding refractory to endoscopic hemostasis. Materials and Methods: This was a retrospective analysis of 116 patients with peptic ulcer bleeding refractory to endoscopic treatment at our institution. Eighty-three cases were treated with surgery, and 33 cases were managed with TAE. Clinical outcomes were evaluated. Results: There were no differences between groups with respect to the mortality rate (p > 0.05), length of hospital stay, or medical diseases related to mortality. The TAE group exhibited a significantly higher rebleeding rate (p < 0.05). Rebleeding predominantly occurred in patients with type Ia peptic ulcers (Forrest classification) irrespective of the treatment approach. The rebleeding rates in such patents were 30.2% and 56.3% in the surgery and TAE groups, respectively. Patients with rebleeding after further therapy showed high mortality rates (68.6%). The rebleeding rate was not significantly different between the subgroups of patients with type Ia lesions, although there was a higher mortality rate in the TAE group (27.9% vs. 75%, p = 0.001). Conclusions: TAE may be the first-choice therapy for patients with peptic ulcer bleeding refractory to endoscopic treatment, whereas emergency surgery may be used as an alternative in patients with type Ia bleeding at institutions with no 24-hour radiology service or when no experienced radiologist is available.展开更多

In as many as ...Intractable bleeding from gastric and duodenal ulcers is associated with significant morbidity and mortality. Aggressive treatment with early endoscopic hemostasis is essential for a favourable outcome. In as many as 12%-17% of patients,endoscopy is either not available or unsuccessful. Endovascular therapy with selective catheterization of the culprit vessel and injection of embolic material has emerged as an alternative to emergent operative intervention in high-risk patients. There has not been a systematic literature review to assess the role for embolotherapy in the treatment of acute upper gastrointestinal bleeding from gastroduo-denal ulcers after failed endoscopic hemostasis. Here,we present an overview of indications,techniques,and clinical outcomes after endovascular embolization of acute peptic-ulcer bleeding. Topics of particular relevance to technical and clinical success are also discussed. Our review shows that transcatheter arterial embolization is a safe alternative to surgery for massive gastroduodenal bleeding that is refractory to endoscopic treatment,can be performed with high technical and clinical success rates,and should be considered the salvage treatment of choice in patients at high surgical risk.展开更多

Of these, 202 patients (152 males, 50females) received epinephrine injection therapy while 91patients (59 males, 32 females) received combination therapy. The choice of endoscopic therapy was made by the endoscopist. Hemostatic rates, rebleeding rates, need for emergency surgery and 30-d mortality were the outcome measures studied.RESULTS: Patients who received combination therapy were significantly older (mean age 66±16 years, range24-90 years) and more suffered from chronic renal failure compared to those who received epinephrine injection therapy alone (mean age 61±17 years, range 21-89 years).Failure to achieve permanent hemostasis was 4% in the group who received epinephrine injection alone and 11%in the group who received combination therapy. When the differences in age and renal function between the two treatment groups were taken into account by multivariate analysis, the rates of initial hemostasis,rebleeding rates, need for surgery and 30-d mortality for both treatment options were not significantly different.CONCLUSION: Combination therapy of epinephrine injection with endoscopic hemoclip application is an effective method of achieving hemostasis in bleeding peptic ulcer diseases. However, superiority of combination therapy over epinephrine injection alone, could not be demonstrated.展开更多
文摘BACKGROUND Second-look endoscopy(SLE)to prevent recurrent bleeding in patients with peptic ulcer disease(PUD)and those undergoing endoscopic submucosal dissection(ESD)is routinely being performed.Conflicting evidence exists regarding efficacy,risk,benefit,and cost-effectiveness.AIM To identify the role and effectiveness of SLE in ESD and PUD,associated rebleeding and PUD-related outcomes like mortality,hospital length of stay,need for endoscopic or surgical intervention and blood transfusions.METHODS A systematic review of literature databases PubMed,Cochrane,and Embase was conducted from inception to January 5,2023.Randomized controlled trials that compared patients with SLE to those who did not have SLE or evaluated the role of prophylactic hemostasis during SLE compared to other conservative interventions were included.The study was conducted per PRISMA guidelines,and the protocol was registered in PROSPERO(ID CRD42023427555:).RevMan was used to perform meta-analysis,and Mantel-Haenszel Odds ratio(OR)were generated using random effect models.RESULTS A total of twelve studies with 2687 patients were included in our systematic review and meta-analysis,of which 1074 patients underwent SLE after ESD and 1613 patients underwent SLE after PUD-related bleeding.In ESD,the rates of rebleeding were 7%in the SLE group compared to 4.4%in the non-SLE group with OR 1.65,95%confidence intervals(CI)of 0.96 to 2.85;P=0.07,whereas it was 11%in the SLE group compared to 13%in the non-SLE group with OR 0.895%CI:0.50 to 1.29;P=0.36.The mean difference in the blood transfusion rates in the SLE and no SLE group in PUD was OR 0.01,95%CI:-0.22 to 0.25;P=0.91.In SLE vs non-SLE groups with PUD,the OR for Endoscopic intervention was 0.29,95%CI:0.08 to 1.00;P=0.05 while it was OR 2.03,95%CI:0.95 to 4.33;P=0.07,for surgical intervention.The mean difference in the hospital length of stay was-3.57 d between the SLE and no SLE groups in PUD with 95%CI:-7.84 to 0.69;P=0.10,denoting an average of approximately 3 fewer days of hospital stay among patients with PUD who underwent SLE.For mortality between SLE and non-SLE groups in PUD,the OR was 0.88,95%CI:0.45 to 1.72;P=0.70.CONCLUSION SLE does not confer any benefit in preventing ESD and PUD-associated rebleeding.SLE also does not provide any significant improvement in mortality,need for interventions,or blood transfusions in PUD patients.SLE decreases the hospital length of stay on average by 3.5 d in PUD patients.
文摘AIM:To investigate the clinical characteristics and outcomes of idiopathic Helicobacter pylori(H.pylori)-negative and drug-negative]peptic ulcer bleeding(PUB).METHODS:A consecutive series of patients who experienced PUB between 2006 and 2012 was retrospectively analyzed.A total of 232 patients were enrolled in this study.The patients were divided into four groups according to the etiologies of PUB:idiopathic,H.pylori-associated,drug-induced and combined(H.pylori-associated and drug-induced)types.We compared the clinical characteristics and outcomes between the groups.When the silver stain or rapid urease tests were H.pylori-negative,we obtained an additional biopsy specimen by endoscopic re-examination and performed an H.pylori antibody test 6-8 wk after the initial endoscopic examination.For a diagnosis of idiopathic PUB,a negative result of an H.pylori antibody test was confirmed.In all cases,re-bleeding was confirmed by endoscopic examination.For the risk assessment,the Blatchford and the Rockall scores were calculated for all patients.RESULTS:For PUB,the frequency of H.pylori infection was 59.5%(138/232),whereas the frequency of idiopathic cases was 8.6%(20/232).When idiopathic PUB was compared to H.pylori-associated PUB,the idiopathic PUB group showed a higher rate of rebleeding after initial hemostasis during the hospital stay(30%vs 7.4%,P = 0.02).When idiopathic PUB was compared to drug-induced PUB,the patients in the idiopathic PUB group showed a higher rate of rebleeding after initial hemostasis upon admission(30%vs 2.7%,P < 0.01).When drug-induced PUB was compared to H.pylori-associated PUB,the patients in the drug-induced PUB were older(68.49 ± 14.76 years vs 47.83 ± 15.15 years,P< 0.01) and showed a higher proportion of gastric ulcer(77%vs 49%,P < 0.01).However,the Blatchford and the Rockall scores were not significantly different between the two groups.Among the patients who experienced drug-induced PUB,no significant differences were found with respect to clinical characteristics,irrespective of H.pylori infection.CONCLUSION:Idiopathic PUB has unique clinical characteristics such as re-bleeding after initial hemostasis upon admission.Therefore,these patients need to undergo close surveillance upon admission.
文摘AIM To compare the Glasgow-Blatchford score(GBS), Rockall score(RS) and Baylor bleeding score(BBS) in predicting clinical outcomes and need for interventions in patients with bleeding peptic ulcers. METHODS Between January 2008 and December 2013, 1012consecutive patients admitted with peptic ulcer bleeding(PUB) were prospectively followed. The pre-endoscopic RS, BBS and GBS, as well as the post-endoscopic diagnostic scores(RS and BBS) were calculated for all patients according to their urgent upper endoscopy findings. Area under the receiver-operating characteristics(AUROC) curves were calculated for the prediction of lethal outcome, rebleeding, needs for blood transfusion and/or surgical intervention, and the optimal cutoff values were evaluated.RESULTS PUB accounted for 41.9% of all upper gastrointestinal tract bleeding, 5.2% patients died and 5.4% patients underwent surgery. By comparing the AUROC curves of the aforementioned pre-endoscopic scores, the RS best predicted lethal outcome(AUROC 0.82 vs 0.67 vs0.63, respectively), but the GBS best predicted need for hospital-based intervention or 30-d mortality(AUROC0.84 vs 0.57 vs 0.64), rebleeding(AUROC 0.75 vs 0.61 vs 0.53), need for blood transfusion(AUROC 0.83 vs0.63 vs 0.58) and surgical intervention(0.82 vs 0.63 vs 0.52) The post-endoscopic RS was also better than the post-endoscopic BBS in predicting lethal outcome(AUROC 0.82 vs 0.69, respectively).CONCLUSION The RS is the best predictor of mortality and the GBS is the best predictor of rebleeding, need for blood transfusion and/or surgical intervention in patients with PUB. There is no one 'perfect score' and we suggest that these two tests be used concomitantly.

文摘AIM: To determine the frequency of small bowel ulcerative lesions in patients with peptic ulcer and define the significance of those lesions. METHODS: In our prospective study, 60 consecutive elderly patients with upper gastrointestinal bleeding from a peptic ulceration(cases) and 60 matched patients with a non-bleeding peptic ulcer(controls) underwent small bowel capsule endoscopy, after a negative colonoscopy(compulsory in our institution). Controls were evaluated for non-bleeding indications. Known or suspected chronic inflammatory conditions and medication that could harm the gut were excluded. During capsule endoscopy, small bowel ulcerative lesions were counted thoroughly and classified according to Graham classification. Other small bowellesions were also recorded. Peptic ulcer bleeding was controlled endoscopically, when adequate, proton pump inhibitors were started in both cases and controls, and Helicobacter pylori eradicated whenever present. Both cases and controls were followed up for a year. In case of bleeding recurrence upper gastrointestinal endoscopy was repeated and whenever it remained unexplained it was followed by repeat colonoscopy and capsule endoscopy.RESULTS: Forty(67%) cases and 18(30%) controls presented small bowel erosions(P = 0.0001), while 22(37%) cases and 4(8%) controls presented small bowel ulcers(P < 0.0001). Among non-steroidal antiinflammatory drug(NSAID) consumers, 39(95%) cases and 17(33%) controls presented small bowel erosions(P < 0.0001), while 22(55%) cases and 4(10%) controls presented small bowel ulcers(P < 0.0001). Small bowel ulcerative lesions were infrequent among patients not consuming NSAIDs. Mean entry hemoglobin was 9.3(SD = 1.4) g/d L in cases with small bowel ulcerative lesions and 10.5(SD = 1.3) g/dL in those without(P = 0.002). Cases with small bowel ulcers necessitate more units of packed red blood cells. During their hospitalization, 6(27%) cases with small bowel ulcers presented bleeding recurrence most possibly attributed to small bowel ulcers, nevertheless 30-d mortality was zero. Presence of chronic obstructive lung disease and diabetes was related with unexplained recurrence of hemorrhage in logistic regression analysis, while absence of small bowel ulcers was protective(relative risk 0.13, P = 0.05).CONCLUSION: Among NSAID consumers, more bleeders than non-bleeders with peptic ulcers present small bowel ulcers; lesions related to more severe bleeding and unexplained episodes of bleeding recurrence.

文摘AIM To investigate the long-term prognosis in peptic ulcer patients continuing taking antithrombotics after ulcer bleeding, and to determine the risk factors that influence the prognosis. METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the differencewas compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups(70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8(8.2%) vs 15(21.7%), P < 0.05; 65(66.3%) vs 13(18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant(P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients in the continuing group, and the risk of death and developing acute cardiovascular disease was higher in patients in the discontinuing group(log-rank test, P = 0.000 for both). Furthermore, COX regression multivariate analysis revealed that the hazard ratio(HR) for recurrent bleeding was 2.986(95%CI: 067-8.356, P = 0.015) in the continuing group, while HR for death or acute cardiovascular disease was 5.216(95%CI: 1.035-26.278, P = 0.028).CONCLUSION After the occurrence of peptic ulcer bleeding, continuing antithrombotics increases the risk of recurrent bleeding events, while discontinuing antithrombotics would increase the risk of death and developing cardiovascular disease. This suggests that clinicians should comprehensively consider the use of antithrombotics after peptic ulcer bleeding.
文摘Peptic ulcer bleeding is a common disease and recurrent bleeding is an independent risk factor of mortality.Infusion with proton pump inhibitors(PPIs) prevents recurrent bleeding after successful endoscopic therapy.A gastric acidic environment of less than pH 5.4 alters coagulation function and activates pepsin to disaggregate platelet plugs.Gastric acid is secreted by H+,K+-ATPase,naming the proton pump.This update review focuses on the mechanism and the role of PPIs in the clinical management of patients with peptic ulcer bleeding.An intravenous omeprazole bolus followed by high-dose continuous infusion for 72 h after successful endoscopic therapy can prevent the recurrent bleeding.In the Asian,however,the infusion dosage can possibly be diminished whilst preserving favorable control of the intragastric pH and thereby still decreasing rates of recurrent bleeding.Irrespective of the infusion dosage of PPIs,rates of recurrent bleeding remain high in patients with co-morbidities.Because recurrent peptic ulcer bleeding may be prolonged in those with co-morbidities,a lowdose infusion of IV PPIs for up to 7-day may result in better control of recurrent bleeding of peptic ulcers.Due to the inter-patient variability in CYP2C19 genotypes,the infusion form of new generation PPIs,such as esomeprazole,should be promising for the prevention of recurrent bleeding.This article offers a comprehensive review of clinical practice,highlighting the indication,the optimal dosage,the duration,and the potential limitation of PPIs infusion for peptic ulcer bleeding.

文摘BACKGROUND Serum gastrin-17(G-17),pepsinogen I(PGI),and pepsinogen II(PGII)concentrations regulate gastric acid secretion,and hypersecretion of gastric acid increases the risks of peptic ulcer and upper gastrointestinal bleeding.These associations suggest that serum G-17,PGI,and(or)PGII may predict gastrointestinal bleeding risk among peptic ulcer patients.AIM To evaluate the efficacies of serum G-17,PGI,PGII,and PGI/PGII ratio(PGR)for predicting upper gastrointestinal bleeding among peptic ulcer patients.METHODS A total of 199 patients diagnosed with peptic ulcer confirmed by gastroscopy and positivity for Helicobacter pylori by the 14C-urea breath test were recruited,including 107 patients with simple peptic ulcer and 92 cases complicated by upper gastrointestinal bleeding.Serum PGI,PGII,G-17,and PGR were measured by immune methods and compared between bleeding and non-bleeding groups by univariate analysis.The specificity and sensitivity of PGs and G-17 for evaluating upper gastrointestinal bleeding risk were then assessed by constructing receiver operating characteristic(ROC)curves.RESULTS Serum G-17 was significantly higher among peptic ulcer patients with upper gastrointestinal bleeding compared to simple peptic ulcer patients(25.34±14.29 vs 8.84±8.03 pmol/L,t=9.822,P<0.01),whereas serum PGI,PGII,and PGR did not differ significantly between bleeding and non-bleeding groups(all P>0.05).The risk of bleeding was significantly higher among peptic ulcer patients with elevated serum G-17(>15 pmol/L)compared to patients with normal or low serum G-17(73.2%vs 27.4%,χ2=40.72,P<0.01).The area under the ROC curve for serum G-17 was 0.866±0.024,and a cut-off of 9.86 pmol/L yielded 90.2%sensitivity and 68.2%specificity for distinguishing peptic ulcer with and without upper gastrointestinal bleeding.CONCLUSION Serum G-17 is significantly upregulated in peptic ulcer patients and higher levels are predictive of upper gastrointestinal bleeding.Conversely,serum PGI,PGII,and PGR have no predictive value.Further prospective studies are warranted to examine if high G-17 can be used to assess risk of bleeding prior to onset.
文摘AIM: To clarify the frequency of and changes in the cause of peptic ulcer bleeding. METHODS: This study retrospectively evaluated the out- and inpatients who underwent endoscopy between 2002 to 2008. The subjects were patients presenting with peptic ulcer bleeding. The details of these patients were obtained from their endoscopic reports and medical records. RESULTS: The rates of Helicobacter pylori (H. pylori ) infection were significantly low (P = 0.039), while the proportion of nonsteroidal antiinflammatory drugs (NSAIDs) users and vascular disease significantly increased over the period studied (P = 0.034 and P = 0.04, respectively). However, there was no significant difference in the proportion of low-dose aspirin users (P = 0.832).CONCLUSION: It's found that the primary cause of peptic ulcer bleeding changed from H. pylori infection to use of NSAIDs over the 7-year period of study. It seems that the number of low-dose aspirin users has increased with the increase in the proportion of vascular disease. It is necessary to take measures to prevent peptic ulcer bleeding among NSAIDs and low dose aspirin users.

文摘AIM: Helicobacter pylori (H pylon) has been linked to chronic gastritis, peptic ulcers, gastric cancer and MALT-lymphoma. Conventional invasive tests are less sensitive than non-invasive tests in diagnosing H pylori infection in patients with bleeding peptic ulcers. Polymerase chain reaction is a sensitive and accurate method for diagnosing H pylori infection. The aim of this study was to evaluate the diagnostic role of mucosai polymerase chain reaction for H pylori infection in patients with bleeding peptic ulcers. METHODS: In patients with bleeding, non-bleeding peptic ulcers and chronic gastritis, we checked rapid urease test, histology, bacterial culture and mucosai polymerase chain reaction fordetecting H pylori infection. Positive H pylori infection was defined as positive culture or both a positive histology and a positive rapid urease test. For mucosai polymerase chain reaction of H pylori, we checked vacA (s1a, s1b, s1c, s2, m1, m1T, m2), iceA1, iceA2. and cag A. RESULTS: Between October 2000 and April 2002,88 patients with bleeding peptic ulcers (males/females: 60/28, gastric ulcers/duodenal ulcers: 55/33), 81 patients with non-bleeding peptic ulcers (males/females: 54/27, gastric ulcers/duodenal ulcers: 45/36) and 37 patients with chronic gastritis (males/ females: 24/13) were enrolled in this study. In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, 45 patients (51%), 71 patients (88%) and 20 patients (54%) respectively were found to have positive H pylori infection (P<0.001). In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, polymerase chain reaction for H pylori infection was positive in 54 patients (61%), 70 patients (86%) and 20 patients (54%) respectively (P<0.001). The sensitivity, positive predictive value and diagnostic accuracy of mucosai polymerase reaction for H pylori infection were significantly lower in patients with bleeding peptic ulcers (84%, 79% and 81%) than in patients with non-bleeding peptic ulcers (99%, 99% and 98%) (P<0.001, P<0.01 and P<0.001 respectively). The sensitivity, negative predictive value and diagnostic accuracy of mucosal polymerase reaction for H py/ori were significantly lower in patients with bleeding peptic ulcers (84%, 83% and 81%) than in patients with chronic gastritis (100%, 100% and 100%) (P= 0.02, P= 0.02 and P=0.001). CONCLUSION: Mucosal polymerase chain reaction for detecting H pylori infection is not reliable in patients with bleeding peptic ulcers.

文摘AIM: To assess the sensitivity and specificity of polymerase chain reaction (PCR) in detecting Helicobacter pylori(H pylon) infection in patients with bleeding peptic ulcers, and to compare its diagnostic efficacy with other invasive and non-invasive tests. METHODS: From April to September 2002, H pylori status in 60 patients who consecutively presented with gastroduodenal ulcer bleeding was examined by rapid urease tests (RUT), histology, culture, PCR, serology and urea breath tests (UBT). RESULTS: The sensitivity of PCR was significantly higher than that of RUT, histology and culture (91% vs 66%, 43% and 37%, respectively; P = 0.01, <0.001, <0.001, respectively), but similar to that of serology (94%) and UBT (94%). Additionally, PCR exhibited a greater specificity than serology (100% vs 65%, P<0.01). However, the specificity of PCR did not differ from that of other tests. Further analysis revealed significant differences in the sensitivities of RUT, culture, histology and PCR between the patients with and those without blood in the stomach (P<0.01, P= 0.09, P<0.05, and P<0.05, respectively). CONCLUSION: PCR is the most accurate method among the biopsy-based tests to detect H pylori infection in patients with bleeding peptic ulcers. Blood may reduce the sensitivities of all biopsy-based tests.
文摘AIM:To compare the recurrent bleeding after endoscopic injection of different epinephrine volumes with hemoclips in patients with bleeding peptic ulcer.METHODS:Between January 2005 and December 2009,150 patients with gastric or duodenal bleeding ulcer with major stigmata of hemorrhage and nonbleeding visible vessel in an ulcer bed(Forrest Ⅱa) were included in the study.Patients were randomized to receive a small-volume epinephrine group(15 to 25 mL injection group;Group 1,n = 50),a large-volume epinephrine group(30 to 40 mL injection group;Group 2,n = 50) and a hemoclip group(Group 3,n = 50).The rate of recurrent bleeding,as the primary outcome,was compared between the groups of patients included in the study.Secondary outcomes compared between the groups were primary hemostasis rate,permanent hemostasis,need for emergency surgery,30 d mortality,bleeding-related deaths,length of hospital stay and transfusion requirements.RESULTS:Initial hemostasis was obtained in all patients.The rate of early recurrent bleeding was 30%(15/50) in the small-volume epinephrine group(Group 1) and 16%(8/50) in the large-volume epinephrine group(Group 2)(P = 0.09).The rate of recurrent bleeding was 4%(2/50) in the hemoclip group(Group 3);the difference was statistically significant with regard to patients treated with either small-volume or large-volume epinephrine solution(P = 0.0005 and P = 0.045,respectively).Duration of hospital stay was significantly shorter among patients treated with hemoclips than among patients treated with epinephrine whereas there were no differences in transfusion requirement or even 30 d mortality between the groups.CONCLUSION:Endoclip is superior to both small and large volume injection of epinephrine in the prevention of recurrent bleeding in patients with peptic ulcer.
文摘Peptic ulcer bleeding is a serious medical problem with significant morbidity and mortality.Endoscopic therapy significantly reduces further bleeding,surgery and mortality in patients with bleeding peptic ulcers and is now recommended as the first hemostatic modality for these patients.The efficacy of large-dose proton pump inhibitor(PPI) therapy in reducing re-bleeding after endoscopic therapy has been supported by evidence derived from randomized controlled trials.It may be premature to recommend small-dose intravenous injection PPI after endoscopic hemostasis in patients with bleeding ulcers.An updated systematic review shows that PPI therapy before endoscopy significantly reduces the proportion with major stigmata and requirement for endoscopic therapy at index endoscopy.Some studies show that there is no significant difference between oral and intravenous PPIs in raising intragastric pH.However,clinical data is lacking in patients with peptic ulcer bleeding to date.
文摘AIM: To compare the effect of intravenous and oral omeprazole in patients with bleeding peptic ulcers without high-risk stigmata.METHODS: This randomized study included 211 patients [112 receiving iv omeprazole protocol (Group 1), 99 receiving po omeprazole 40 mg every 12 h (Group 2)] with a mean age of 52.7. In 144 patients the ulcers showed a clean base, and in 46 the ulcers showed fiat spots and in 21 old adherent clots. The endpoints were re-bleeding, surgery, hospital stay, blood transfusion and death. After discharge, re-bleeding and death were reevaluated within 30 d.RESULTS: The study groups were similar with respect to baseline characteristics. Re-bleeding was recorded in 5 patients of Group 1 and in 4 patients of Group 2 (P = 0.879). Three patients in Group 1 and 2 in Group 2 underwent surgery (P = 0.773). The mean length of hospital stay was 4.6 ± 1.6 d in Group 1 vs 4.5 ± 2.6 d in Group 2 (P = 0.710); the mean amounts of blood transfusion were 1.9 ±1.1 units in Group 1 vs 2.1 ±1.7 units in Group 2 (P = 0.350). Four patients, two in each group died (P = 0.981). After discharge, a new bleeding occurred in 2 patients of Group 1 and in 1 patient of Group 2, and one patient from Group 1 died.CONCLUSION: We demonstrate that the effect of oral omeprazole is as effective as intravenous therapy in terms of re-bleeding, surgery, transfusion requirements, hospitalization and mortality in patients with bleeding ulcers with low risk stigmata. These patients can be treated effectively with oral omeprazole.
文摘<strong>Objective:</strong> To assess and compare the clinical application value of nursing risk management in the diagnosis and treatment of severe peptic ulcer bleeding. <strong>Methods:</strong> A total of 70 patients with severe peptic ulcer bleeding were selected as the research objects, randomly divided into observation group and control group, 35 cases for each. The nursing risk management and conventional nursing management were implemented for the two groups, respectively. The success rate of hemostasis, average length of stay, cure rate, complication rate, dyspnea rate, nursing dispute rate, SAS score, and SDS score were compared between the two groups. Patients’ satisfaction with nursing quality was also compared. <strong>Results:</strong> After the implementation of two different nursing management methods, all the above-mentioned metrics were better in the observation group than in the control group, and the differences were statistically significant (P < 0.01 or P < 0.05). <strong>Conclusion:</strong> The application of nursing risk management in the nursing intervention process of patients with severe peptic ulcer bleeding can effectively reduce the probability of nursing risk events, increase the cure rate, shorten the patient’s hospital stay, but also improve the patients’ psychological state and increase the patient’s satisfaction with nursing quality, which is worth clinical promotion.
文摘Current guidelines for managing ulcer bleeding state that patients with major stigmata should be managed by dual endoscopic therapy(injection with epinephrine plus a thermal or mechanical modality) followed by a high dose intravenous infusion of proton pump inhibitors(PPIs).This paper aims to review and critically evaluate evidence supporting the purported superiority of a continuous infusion over less intensive regimens of PPIs administration and the need for adding a second hemostatic endoscopic procedure to epinephrine injection.Systematic searches of PubMed,EMBASE and the Cochrane library were performed.There is strong evidence for an incremental benefit of PPIs over H2receptor antagonists or placebo for the outcome of patients with peptic ulcer bleeding following endoscopic hemostasis.However,the benefit of PPIs is unrelated to either the dosage(intensive vs standard regimen) or the route of administration(intravenous vs oral).There is significant heterogeneity among the 15 studies that compared epinephrine with epinephrine plus a second modality,which might preclude the validity of reported summary estimates.Studies without second look endoscopy plus re-treatment of re-bleeding lesions showed a signif icant benef it of adding a second endoscopic modality for hemostasis,while studies with second-look and re-treatment showed equal efficacy between endoscopic mono and dual therapy.Inconclusive experimental evidence supports the current recommendation of the use of dual endoscopic hemostatic means and infusion of high-dose PPIs as standard therapy for patients with bleeding peptic ulcers.Presently,the combination of epinephrine monotherapy with standard doses of PPIs constitutes an appropriate treatment for the majority of patients.
文摘Acute upper gastrointestinal bleeding (UGIB) remains an important emergency situation. In the last two decades, major developments took place influencing incidence, etiology and outcome of patients with acute UGIB. Peptic ulcer bleeding is the most significant complication of ulcer disease being responsible for 50% of all cases mortality. Aim of the study: To compare between endoscopic clip application versus argon plasma coagulation in management of bleeding peptic ulcer (BPU). Patients and Methods: Sixty patients suffering from acute UGIB were randomly divided into two groups: group I included 30 patients treated with endoscopic clip application and Group II included 30 patients subjected to endoscopic APC. All patients were classified according to Forrest classification and the clinical Rockall score. Results: There were significant differences between the two groups as regard Forrest classification (P 0.05). Re bleeding was significant with higher Rockall score in group I (P 0.05). Conclusion: Endoscopic application of hemoclips have a less re bleeding rate than Argon plasma coagulation for treatment of bleeding peptic ulcer, although this was statistically insignificant, meanwhile APC is still less cost and easy. Clinical and endoscopic assessment (through Rokcall score and Forrest classification) could help in making best choice for endoscopic management.
文摘Background: Before the advent of transcatheter arterial embolization (TAE), emergency surgery was the only choice for patients with peptic ulcer bleeding refractory to endoscopic therapy. This study compared the effectiveness of TAE and surgery in patients with peptic ulcer bleeding refractory to endoscopic hemostasis. Materials and Methods: This was a retrospective analysis of 116 patients with peptic ulcer bleeding refractory to endoscopic treatment at our institution. Eighty-three cases were treated with surgery, and 33 cases were managed with TAE. Clinical outcomes were evaluated. Results: There were no differences between groups with respect to the mortality rate (p > 0.05), length of hospital stay, or medical diseases related to mortality. The TAE group exhibited a significantly higher rebleeding rate (p < 0.05). Rebleeding predominantly occurred in patients with type Ia peptic ulcers (Forrest classification) irrespective of the treatment approach. The rebleeding rates in such patents were 30.2% and 56.3% in the surgery and TAE groups, respectively. Patients with rebleeding after further therapy showed high mortality rates (68.6%). The rebleeding rate was not significantly different between the subgroups of patients with type Ia lesions, although there was a higher mortality rate in the TAE group (27.9% vs. 75%, p = 0.001). Conclusions: TAE may be the first-choice therapy for patients with peptic ulcer bleeding refractory to endoscopic treatment, whereas emergency surgery may be used as an alternative in patients with type Ia bleeding at institutions with no 24-hour radiology service or when no experienced radiologist is available.

文摘BACKGROUND In monotherapy studies for bleeding peptic ulcers,large volumes of epinephrine were associated with a reduction in rebleeding.However,the impact of epinephrine volume in patients treated with combination endoscopic therapy remains unclear.AIM To assess whether epinephrine volume was associated with bleeding outcomes in individuals who also received endoscopic thermal therapy and/or clipping.METHODS Data from 132 patients with Forrest class Ia,Ib,and IIa peptic ulcers were reviewed.The primary outcome was further bleeding at 7 d;secondary outcomes included further bleeding at 30 d,need for additional therapeutic interventions,post-endoscopy blood transfusions,and 30-day mortality.Logistic and linear regression and Cox proportional hazards analyses were performed.RESULTS There was no association between epinephrine volume and all primary and secondary outcomes in multivariable analyses.Increased odds for further bleeding at 7 d occurred in patients with elevated creatinine values(aOR 1.96,95%CI 1.30-3.20;P<0.01)or hypotension requiring vasopressors(aOR 6.34,95%CI 1.87-25.52;P<0.01).Both factors were also associated with all secondary outcomes.CONCLUSION Epinephrine maintains an important role in the management of bleeding ulcers,but large volumes up to a range of 10-20 mL are not associated with improved bleeding outcomes among individuals receiving combination endoscopic therapy.Further bleeding is primarily associated with patient factors that likely cannot be overcome by increased volumes of epinephrine.However,in carefully-selected cases where ulcer location or size pose therapeutic challenges or when additional modalities are unavailable,it is conceivable that increased volumes of epinephrine may still be beneficial.
文摘Intractable bleeding from gastric and duodenal ulcers is associated with significant morbidity and mortality. Aggressive treatment with early endoscopic hemostasis is essential for a favourable outcome. In as many as 12%-17% of patients,endoscopy is either not available or unsuccessful. Endovascular therapy with selective catheterization of the culprit vessel and injection of embolic material has emerged as an alternative to emergent operative intervention in high-risk patients. There has not been a systematic literature review to assess the role for embolotherapy in the treatment of acute upper gastrointestinal bleeding from gastroduo-denal ulcers after failed endoscopic hemostasis. Here,we present an overview of indications,techniques,and clinical outcomes after endovascular embolization of acute peptic-ulcer bleeding. Topics of particular relevance to technical and clinical success are also discussed. Our review shows that transcatheter arterial embolization is a safe alternative to surgery for massive gastroduodenal bleeding that is refractory to endoscopic treatment,can be performed with high technical and clinical success rates,and should be considered the salvage treatment of choice in patients at high surgical risk.
文摘AIM: To assess the efficacy of hemoclip application in combination with epinephrine injection in the treatment of bleeding peptic ulcers and to compare the clinical outcomes between patients treated with such a combination therapy and those treated with epinephrine injection alone.METHODS: A total of 293 patients (211 males, 82females) underwent endoscopic therapy for bleeding peptic ulcers. Of these, 202 patients (152 males, 50females) received epinephrine injection therapy while 91patients (59 males, 32 females) received combination therapy. The choice of endoscopic therapy was made by the endoscopist. Hemostatic rates, rebleeding rates, need for emergency surgery and 30-d mortality were the outcome measures studied.RESULTS: Patients who received combination therapy were significantly older (mean age 66±16 years, range24-90 years) and more suffered from chronic renal failure compared to those who received epinephrine injection therapy alone (mean age 61±17 years, range 21-89 years).Failure to achieve permanent hemostasis was 4% in the group who received epinephrine injection alone and 11%in the group who received combination therapy. When the differences in age and renal function between the two treatment groups were taken into account by multivariate analysis, the rates of initial hemostasis,rebleeding rates, need for surgery and 30-d mortality for both treatment options were not significantly different.CONCLUSION: Combination therapy of epinephrine injection with endoscopic hemoclip application is an effective method of achieving hemostasis in bleeding peptic ulcer diseases. However, superiority of combination therapy over epinephrine injection alone, could not be demonstrated.
