METHODS: A pig model of pancreatic ductal dilation was made by ligating the main pancreatic duct. After 4 wk ligation, a total of 36 piglets were divided randomly into four groups. The piglets in the control group underwent laparotomy only; the others were treated by three anastomoses: (1) end-to-end pancreaticojejunostomy invagination (EEPJ); (2) end-to-side duct-to- mucosa sutured anastomosis (ESPJ); or (3) binding pancreaticojejunostomy (BPJ). Anastomotic patency was assessed after 8 wk by body weight gain, intrapancreatic ductal pressure, pancreatic exocrine function secretin test, pancreatography, and macroscopic and histologic features of the anastomotic site. RESULTS: The EEPJ group had significantly slower weight gain than the ESPJ and BPJ groups on postoperative weeks 6 and 8 (P < 0.05). The animals in both the ESPJ and BPJ groups had a similar body weight gain.Intrapancreatic ductal pressure was similar in ESPJ and BPJ. However, pressure in EEPJ was significantly higher than that in ESPJ and BPJ (P < 0.05). All three functional parameters, the secretory volume, the flow rate of pancreatic juice, and bicarbonate concentration, were significantly higher in ESPJ and BPJ as compared to EEPJ (P < 0.05). However, the three parameters were similar in ESPJ and BPJ. Pancreatography performed after EEPJ revealed dilation and meandering of the main pancreatic duct, and the anastomotic site exhibited a variable degree of occlusion, and even blockage. Pancreatography of ESPJ and BPJ, however, showed normal ductal patency. Histopathology showed that the intestinal mucosa had fused with that of the pancreatic duct, with a gradual and continuous change from one to the other. For EEPJ, the portion of the pancreatic stump protruding into the jejunal lumen was largely replaced by cicatricial fibrous tissue. CONCLUSION: A mucosa-to-mucosa pancreatico- jejunostomy is the best choice for anastomotic patency when compared with EEPJ. BPJ can effectively maintain anastomotic patency and preserve pancreatic exocrine function as well as ESPJ.展开更多

The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract, in a non-invasive manner. The available clinical trials have demonstrated that the Patency capsule is a good tool for assessment of the functional patency of the small bowel, and it allows identification of those patients who can safely undergo a capsule endoscopy, despite clinical and radiographic evidence of small-bowel obstruction. Some cases of intestinal occlusion have been reported with the Patency capsule, four of them needed surgery. So, a new capsule with two timer plugs (Agile capsule) has been recently developed in order to minimize the risk of occlusion. This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.展开更多

Although stent patency was longer in the RT group than that in the non-RT group(140.7±51.3 vs136.4±34.9 days, P=0.94), the difference was not statistically significant. There were a lower rate of stent occlusion(27.8% vs50.0% of patients, P=0.12) and a longer overall survival(420.1 ±73.2 vs 269.1±41.7 days, P=0.11) in the RT group than in the non-RT group, and the difference again was not statistically significant. The development of adverse reactions did not differ(55.6% vs 53.1% of patients, P=0.91). There was no serious adverse reaction in both groups(P=0.99).CONCLUSIONS: EBRT did not significantly improve stent patency in patients with inoperable BDC having uncovered metallic stents. However, EBRT was safe. Future trials withrefined protocols for better efficacy are expected.展开更多

METHODS:A total of 116 patients underwent stent placements for inoperable malignant gastroduodenal obstruction at a tertiary academic center. Clinical success was defined as acceptable decompression of the obstructive lesion within the malignant gastroduodenal neoplasm. We evaluated patient comorbidities and clinical statuses using the World Health Organization's scoring system and categorized patient responses to chemotherapy using the Response Evaluation Criteria in Solid Tumors criteria. We analyzed the relationships between possible predictive factors and stent patency. RESULTS:Self-expandable metallic stent placement was technically successful in all patients(100%),and the clinical success rate was 84.2%. In a multivariate Cox proportional hazards model,carcinoembryonic antigen(CEA) levels were correlated with a reduction in stent patency [P = 0.006; adjusted hazard ratio(a HR)= 2.92,95%CI:1.36-6.25]. Palliative chemotherapy was statistically associated with an increase in stent patency(P = 0.009; a HR = 0.27,95%CI:0.10-0.72).CONCLUSION:CEA levels can easily be measured at the time of stent placement and may help clinicians to predict stent patency and determine the appropriate stent procedure.展开更多

Routine HSG may result in loss or damage to the hymen and loss of virginity. Aim: The aim of the procedure of retrograde dye test was explored to see the possibility of assessing tubal patency during laparotomy. Case Presentation: At laparotomy and after myomectomy in a 32 year old virgin, a moderate sized Wilkinson’s cannula was gently inserted at the fimbrial end of the both tubes and 50mls of dilute Methylene-Blue solution was injected in each tube at a time to see whether the dye will appear at the vagina introitus. There was no resistance to flow of the dye in both tubes. Inspection of the vaginal introitus revealed a gush of dye flowing through it as the dye was introduced through each tube confirming the patency of both tubes. Conclusion: Retrograde dye test at the time of abdominal procedures like myomectomy, pelvic adhesiolysis and excision of endometriotic cyst can be cost effective. This procedure is also useful in assessing tubal patency for women who undergo laparotomy and also wish to preserve their virginity.展开更多

Use of heparin as a flushing solution in maintaining patency of intra- arterial catheters has been a recognizedpractice. Due to its anticoagulation properties, heparin can cause side effects like heparin-induced thromhocytopenia in hypersensitivepatients. The alternative, normal saline solution increases the accuracy of patients' coagulation status and enhances safer clinicalpractice. A systematic search was conducted at Cochrane Library, Medline, CINAHL, OVID and Joanna Briggs Institute. Reviewperiod covered from 1990 to 2011. Methodological validity of included studies was evaluated using SIGN grading checklists fromScottish Intercollegiate Guidelines Network. There is inconsistent evidence and sample sizes were too small to allow statisticalsignificance to be achieved. Meta-analysis was performed for 2 studies; results revealed that heparinised saline offers no addedadvantage over normal saline. There is insufficient evidence to support the use of heparinised saline for flushing arterial catheters. Arigorous research design is needed to determine variables known to influence patency of arterial catheters. Sound clinical judgementmust be exercised in situations that require the need of heparinised saline.展开更多

Methods Coronary artery angiography (CAG) was performed in 124 out of 1406 patients with AMI receiving IV UK (UKTP) (Guangdong Techpool Biochemical Pharmaceutical Co. Ltd. Guangzhou, China) from November 1994 to April 1996. 1.5 million units of UKTP were infused in 111 patients, 2.0 million units in 10 patients and 1.0 million in 3 cases within 30 minutes. CAG was performed 90 minutes after the initiation of thrombolytic therapy. Results Fifty two patients had coronary flow grade of TIMI 3 and 38 patients TIMI 2 90 minutes after the onset of thrombolytic therapy. The total patency rate of infarct related artery (IRA) was 72.6%. There was no significant difference ( P >0.05) in the patency rate of IRA of various locations. The patency rate of LAD was 71.6% (53/74), of RCA was 71.4% (30/42), of LCX was 85.7% (6/7) and effective patency in one patient with left main artery occlusion. Although there was a tendency that the earlier the thrombolytic therapy, the higher the patency rate of IRA patency, the results did not meet the statistically significant level (P>0.05). Using CAG as the gold standard, the clinical criteria used for evaluation of reperfusion rate had a sensitivity of 88%, specificity of 69% and accuracy of 83% in prediction of the reperfusion of IRA. Conclusion UK is effective and reliable in IV thrombolytic therapy of AMI. The clinical criteria used to predict reperfusion of IRA have a higher sensitivity and relatively lower specificity.展开更多

However, the main problem with stent placement is the relatively short duration of stent patency.Although self-expanding metal stents(SEMSs) have a longer patency period than plastic stents(PSs), the higher costs limit the wide use of SEMSs. A PS with an antireflux valve is an attractive idea to prolong stent patency, but no ideal design for an antireflux PS(ARPS) has been proposed. We developed a new ARPS with a "duckbilled" valve attached to the duodenal end of the stent.AIM To compare the patency of ARPSs with that of traditional PSs(TPSs) in patients with unresectable distal MBO.METHODS We conducted a single-center, prospective, randomized, controlled, double-blind study. This study was conducted at the West China Hospital of Sichuan University. Consecutive patients with extrahepatic MBO were enrolled prospectively. Eligible patients were randomly assigned to receive either an ARPS or a TPS. Patients were followed by clinic visits or telephone interviews every 1-2 mo until stent exchange, death, or the final study follow-up in October 2018. The primary outcome was the duration of stent patency. Secondary outcomes included the rate of technical success, the rate of clinical success,adverse events, and patient survival.RESULTS Between February 2016 and December 2017, 38 patients were randomly assigned to two groups, with 19 patients in each group, to receive ARPSs or TPSs. Stent insertion was technically successful in all patients. There were no significant differences between the two groups in the rates of clinical success or the rates of early or late adverse events(P = 0.660, 1.000, and 1.000, respectively). The median duration of stent patency in the ARPS group was 285 d [interquartile range(IQR),170], which was significantly longer than that in the TPS group(median, 130 d;IQR, 90, P = 0.005). No significant difference in patient survival was noted between the two groups(P = 0.900).CONCLUSION The new ARPS is safe and effective for the palliation of unresectable distal MBO,and has a significantly longer stent patency than a TPS.展开更多

METHODS: Twenty five patients with Budd-Chiari syndrome admitted to Ain Shams University Hospitals, Tropical Medicine Department were included. Twelve patients (48%) with short segment occlusion were candidates for angioplasty; with stenting in ten cases and without stenting in two. Thirteen patients (52%) had Transjugular Intrahepatic Portosystemic Shunt. Patients were followed up for 12-32 mo. RESULTS: Patency rate in patients who underwent angioplasty ± stenting was 83.3% at one year and at end of follow up. The need of revision was 41.6% with one year survival of 100%, dropped to 91.6% at end of follow up. In patients who had Transjugular Intrahepatic Portosystemic Shunt, patency rate was 92.3% at one year, dropped to 84.6% at end of follow up. The need of revision was 38.4% with one year and end of follow up survival of 100%. Patients with patent shunts showed marked improvement compared to those with occluded shunts. CONCLUSION: Morbidity and mortality following angioplasty ± stenting and TIPS are low with satisfactory outcome. Proper patient selection and management of shunt dysfunction are crucial in improvement.展开更多

VCE has been shown to play a role in monitoring the activity of small bowel Crohn’s disease and can be used to assess the response to anti-inflammatory treatment in Crohn’s disease. For those patients with Crohn’s disease who have undergone an intestinal resection, VCE has been assessed as a tool to detect post-operative recurrence. VCE may also aid in the reclassification of patients with a diagnosis of Inflammatory Bowel Disease Unclassified to Crohn’s disease. The evolution of colon capsule endoscopy (CCE) has expanded the application of this technology further. The use of CCE to assess the activity of ulcerative colitis has been described. This advance in capsule technology has also fuelled interest in its potential role as a minimally invasive tool to assess the whole of GI tract opening the possibility of its use for the panenteric assessment of Crohn’s disease. VCE is a safe procedure. However, the risk of a retained capsule is higher in patients with suspected or confirmed Crohn’s disease compared with patients having VCE examination for other indications.

文摘Objective:Bladder neck contracture and vesicourethral anastomotic stenosis are difficult to manage endoscopically,and open repair is associated with high rates of incontinence.In recent years,there have been increasing reports of robotic-assisted bladder neck reconstruction in the literature.However,existing studies are small,heterogeneous case series.The objective of this study was to perform a systematic review of robotic-assisted bladder neck reconstruction to better evaluate patency and incontinence outcomes.Methods:We performed a systematic review of PubMed from first available date to May 2023 for all studies evaluating robotic-assisted reconstructive surgery of the bladder neck in adult men.Articles in non-English,author replies,editorials,pediatric-based studies,and reviews were excluded.Outcomes of interest were patency and incontinence rates,which were pooled when appropriate.Results:After identifying 158 articles on initial search,we included only ten studies that fit all aforementioned criteria for robotic-assisted bladder neck reconstruction.All were case series published from March 2018 to March 2022 ranging from six to 32 men,with the median follow-up of 5e23 months.A total of 119 patients were included in our analysis.A variety of etiologies and surgical techniques were described.Patency rates ranged from 50%to 100%,and pooled patency was 80%(95/119).De novo incontinence rates ranged from 0%to 33%,and pooled incontinence was 17%(8/47).Our findings were limited by small sample sizes,relatively short follow-ups,and heterogeneity between studies.
文摘AIM:To assess the patency of pancreaticoenterostomy and pancreatic exocrine function after three surgical methods. METHODS: A pig model of pancreatic ductal dilation was made by ligating the main pancreatic duct. After 4 wk ligation, a total of 36 piglets were divided randomly into four groups. The piglets in the control group underwent laparotomy only; the others were treated by three anastomoses: (1) end-to-end pancreaticojejunostomy invagination (EEPJ); (2) end-to-side duct-to- mucosa sutured anastomosis (ESPJ); or (3) binding pancreaticojejunostomy (BPJ). Anastomotic patency was assessed after 8 wk by body weight gain, intrapancreatic ductal pressure, pancreatic exocrine function secretin test, pancreatography, and macroscopic and histologic features of the anastomotic site. RESULTS: The EEPJ group had significantly slower weight gain than the ESPJ and BPJ groups on postoperative weeks 6 and 8 (P < 0.05). The animals in both the ESPJ and BPJ groups had a similar body weight gain.Intrapancreatic ductal pressure was similar in ESPJ and BPJ. However, pressure in EEPJ was significantly higher than that in ESPJ and BPJ (P < 0.05). All three functional parameters, the secretory volume, the flow rate of pancreatic juice, and bicarbonate concentration, were significantly higher in ESPJ and BPJ as compared to EEPJ (P < 0.05). However, the three parameters were similar in ESPJ and BPJ. Pancreatography performed after EEPJ revealed dilation and meandering of the main pancreatic duct, and the anastomotic site exhibited a variable degree of occlusion, and even blockage. Pancreatography of ESPJ and BPJ, however, showed normal ductal patency. Histopathology showed that the intestinal mucosa had fused with that of the pancreatic duct, with a gradual and continuous change from one to the other. For EEPJ, the portion of the pancreatic stump protruding into the jejunal lumen was largely replaced by cicatricial fibrous tissue. CONCLUSION: A mucosa-to-mucosa pancreatico- jejunostomy is the best choice for anastomotic patency when compared with EEPJ. BPJ can effectively maintain anastomotic patency and preserve pancreatic exocrine function as well as ESPJ.
文摘Small bowel strictures can be missed by current diagnostic methods. The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract, in a non-invasive manner. The available clinical trials have demonstrated that the Patency capsule is a good tool for assessment of the functional patency of the small bowel, and it allows identification of those patients who can safely undergo a capsule endoscopy, despite clinical and radiographic evidence of small-bowel obstruction. Some cases of intestinal occlusion have been reported with the Patency capsule, four of them needed surgery. So, a new capsule with two timer plugs (Agile capsule) has been recently developed in order to minimize the risk of occlusion. This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.

文摘Background:Stent insertion for biliary decompression to relieve jaundice and subsequent biliary infection is necessary for patients with biliary obstruction caused by pancreatic cancer,and it is important to keep the stent patent as long as possible.However,few studies have compared stent patency in terms of chemotherapy in patients with pancreatic cancer.This study aimed to evaluate the differences in stent patency in terms of recently evolving chemotherapy.Methods:Between January 2015 and May 2017,161 patients with pancreatic cancer who had undergone biliary stent insertion with a metal stent were retrospectively analyzed.The relationship between chemotherapy and stent patency was assessed.Additionally,overall survival according to the treatment,risk factors for stent patency,and long-term adverse events were evaluated.Results:Median stent patency was 42 days for patients with the best supportive care and 217 days for patients with chemotherapy(conventional gemcitabine-based chemotherapy and folfirinox)(P<0.001).Furthermore,the folfirinox group showed the longest median stent patency and overall survival,with 283 days and 466 days,respectively(P<0.001)despite higher adverse events rate.Patients who underwent folfirinox chemotherapy after stent insertion had better stent patency in multivariate analysis(HR=0.26;95%CI:0.12–0.60;P=0.001).Conclusions:Compared with patients who received best supportive care only,patients who underwent chemotherapy after stent insertion had better stent patency.More prolonged stent patency can be expected for patients with folfirinox than conventional gemcitabine-based chemotherapy.

文摘In coronary artery bypass grafting(CABG),graft’s poor instant patency may lead to an abnormal hemodynamic environment in anastomosis,which could further cause graft failure after the surgery.This paper investigates the graft hemodynamics with different instant patency,and explores its effect on graft postoperative efficiency.Six CABG 0D/3D coupling multi-scale models which used left internal mammary artery(LIMA)and saphenous vein(SVG)as grafts were constructed.Different types of grafts were examined in the models,including normal grafts,grafts with competitive flow and grafts with anastomotic stenosis.Simulation results indicated that comparing with SVG grafts,there was a greater difference between normal LIMA graft and non-patent LIMA graft.Also,the backflow occurred even in LIMA systolic flow.The wall shear stress(WSS)in the graft of the competitive flow LIMA model had an appreciable decrease comparing with the normal graft.In addition,the WSS in the stenosis region of the anastomotic stenosis LIMA model was much higher than its adjacent regions.In contrast,the WSS distributions in the SVG models were much smoother than in the LIMA models.For oscillatory shear index(OSI),there was little difference between normal LIMA and SVG.But when the graft had competitive flow or anastomotic stenosis,much higher OSI occurred in some regions in LIMA than SVG.There are significant differences in hemodynamics between normal grafts and non-patent grafts both in LIMA and SVG.The hemodynamic environment in a normal LIMA is better than that in a normal SVG.However,in the situation of the two types of non-patent grafts,the hemodynamics of SVG is better than LIMA.
文摘BACKGROUND: Although biliary decompression with metallic stenting is the preferred treatment for inoperable bile duct cancer(BDC), maintenance of patency is still unsatisfactory.We tried to assess the effectiveness and safety of external beam radiotherapy(EBRT) for prolonging stent patency in patients having uncovered metallic stents.METHOD: We retrospectively reviewed 50 patients who received endoscopic stenting, of whom 18 received EBRT(RT group) and 32 did not(non-RT group).RESULTS: No difference was found in baseline characteristics between the two groups. Although stent patency was longer in the RT group than that in the non-RT group(140.7±51.3 vs136.4±34.9 days, P=0.94), the difference was not statistically significant. There were a lower rate of stent occlusion(27.8% vs50.0% of patients, P=0.12) and a longer overall survival(420.1 ±73.2 vs 269.1±41.7 days, P=0.11) in the RT group than in the non-RT group, and the difference again was not statistically significant. The development of adverse reactions did not differ(55.6% vs 53.1% of patients, P=0.91). There was no serious adverse reaction in both groups(P=0.99).CONCLUSIONS: EBRT did not significantly improve stent patency in patients with inoperable BDC having uncovered metallic stents. However, EBRT was safe. Future trials withrefined protocols for better efficacy are expected.

文摘AIM:To investigate the predictive factors of selfexpandable metallic stent patency after stent placement in patients with inoperable malignant gastroduodenal obstruction. METHODS:A total of 116 patients underwent stent placements for inoperable malignant gastroduodenal obstruction at a tertiary academic center. Clinical success was defined as acceptable decompression of the obstructive lesion within the malignant gastroduodenal neoplasm. We evaluated patient comorbidities and clinical statuses using the World Health Organization's scoring system and categorized patient responses to chemotherapy using the Response Evaluation Criteria in Solid Tumors criteria. We analyzed the relationships between possible predictive factors and stent patency. RESULTS:Self-expandable metallic stent placement was technically successful in all patients(100%),and the clinical success rate was 84.2%. In a multivariate Cox proportional hazards model,carcinoembryonic antigen(CEA) levels were correlated with a reduction in stent patency [P = 0.006; adjusted hazard ratio(a HR)= 2.92,95%CI:1.36-6.25]. Palliative chemotherapy was statistically associated with an increase in stent patency(P = 0.009; a HR = 0.27,95%CI:0.10-0.72).CONCLUSION:CEA levels can easily be measured at the time of stent placement and may help clinicians to predict stent patency and determine the appropriate stent procedure.
文摘AIM:To compare the performance of different types of abdominal drains used in bariatric surgery.METHODS:A vertical banded Roux-en-Y gastric bypass was performed in 33 morbidly obese patients.Drainage of the peritoneal cavity was performed in each case using three different types of drain selected in a randomized manner:a latex tubular drain,a Watterman tubulolaminar drain,and a silicone channeled drain.Drain permeability,contamination of the drained fluid,ease of handling,and patient discomfort were evaluated postoperatively over a period of 7 d.RESULTS:The patients with the silicone channeled drain had larger volumes of drainage compared to patients with tubular and tubulolaminar drains between the third and seventh postoperative days.In addition,a lower incidence of discomfort and of contamination with bacteria of a more pathogenic profile was observed in the patients with the silicone channeled drain.CONCLUSION:The silicone channeled drain was more comfortable and had less chance of occlusion,which is important in the detection of delayed dehiscence.
文摘Background: Hysterosalpingogram (HSG) and Laparoscopy and dye tests for tubal assessment for a virgin who places high premium on her virginity could be challenging. Routine HSG may result in loss or damage to the hymen and loss of virginity. Aim: The aim of the procedure of retrograde dye test was explored to see the possibility of assessing tubal patency during laparotomy. Case Presentation: At laparotomy and after myomectomy in a 32 year old virgin, a moderate sized Wilkinson’s cannula was gently inserted at the fimbrial end of the both tubes and 50mls of dilute Methylene-Blue solution was injected in each tube at a time to see whether the dye will appear at the vagina introitus. There was no resistance to flow of the dye in both tubes. Inspection of the vaginal introitus revealed a gush of dye flowing through it as the dye was introduced through each tube confirming the patency of both tubes. Conclusion: Retrograde dye test at the time of abdominal procedures like myomectomy, pelvic adhesiolysis and excision of endometriotic cyst can be cost effective. This procedure is also useful in assessing tubal patency for women who undergo laparotomy and also wish to preserve their virginity.
文摘This paper compares the effectiveness of normal saline and heparinised saline as a flushing solution in maintaining patencyof arterial catheters. Use of heparin as a flushing solution in maintaining patency of intra- arterial catheters has been a recognizedpractice. Due to its anticoagulation properties, heparin can cause side effects like heparin-induced thromhocytopenia in hypersensitivepatients. The alternative, normal saline solution increases the accuracy of patients' coagulation status and enhances safer clinicalpractice. A systematic search was conducted at Cochrane Library, Medline, CINAHL, OVID and Joanna Briggs Institute. Reviewperiod covered from 1990 to 2011. Methodological validity of included studies was evaluated using SIGN grading checklists fromScottish Intercollegiate Guidelines Network. There is inconsistent evidence and sample sizes were too small to allow statisticalsignificance to be achieved. Meta-analysis was performed for 2 studies; results revealed that heparinised saline offers no addedadvantage over normal saline. There is insufficient evidence to support the use of heparinised saline for flushing arterial catheters. Arigorous research design is needed to determine variables known to influence patency of arterial catheters. Sound clinical judgementmust be exercised in situations that require the need of heparinised saline.

文摘Background::Although endovascular therapy has been widely used for focal aortoiliac occlusive disease(AIOD),its performance for extensive AIOD(EAIOD)is not fully evaluated.We aimed to demonstrate the long-term results of EAIOD treated by endovascular therapy and to identify the potential risk factors for the loss of primary patency.Methods::Between January 2008 and June 2018,patients with a clinical diagnosis of the 2007 TransAtlantic Inter-Society Consensus II(TASC II)C and D AIOD lesions who underwent endovascular treatment in our institution were enrolled.Demographic,diagnosis,procedure characteristics,and follow-up information were reviewed.Univariate analysis was used to identify the correlation between the variables and the primary patency.A multivariate logistic regression model was used to identify the independent risk factors associated with primary patency.Five-and 10-year primary and secondary patency,as well as survival rates,were calculated by Kaplan-Meier analysis.Results::A total of 148 patients underwent endovascular treatment in our center.Of these,39.2%were classified as having TASC II C lesions and 60.8%as having TASC II D lesions.The technical success rate was 88.5%.The mean follow-up time was 79.2±29.2 months.Primary and secondary patency was 82.1%and 89.4%at 5 years,and 74.8%and 83.1%at 10 years,respectively.The 5-year survival rate was 84.2%.Compared with patients without loss of primary patency,patients with this condition showed significant differences in age,TASC II classification,infrainguinal lesions,critical limb ischemia(CLI),and smoking.Multivariate logistic regression analysis showed age<61 years(adjusted odds ratio[aOR]:6.47;95%CI:1.47-28.36;P=0.01),CLI(aOR:7.81;95%CI:1.92-31.89;P=0.04),and smoking(aOR:10.15;95%CI:2.79-36.90;P<0.01)were independent risk factors for the loss of primary patency.Conclusions::Endovascular therapy was an effective treatment for EAIOD with encouraging patency and survival rate.Age<61 years,CLI,and smoking were independent risk factors for the loss of primary patency.
文摘Objective To evaluate the efficacy of intravenous (IV) thrombolytic therapy on acute myocardial infarction (AMI) and to evaluate the sensitivity and specificity of clinical criteria in deciding reperfusion rate by using 90 minutes angiography after initiation of the IV urokinase (UK). Methods Coronary artery angiography (CAG) was performed in 124 out of 1406 patients with AMI receiving IV UK (UKTP) (Guangdong Techpool Biochemical Pharmaceutical Co. Ltd. Guangzhou, China) from November 1994 to April 1996. 1.5 million units of UKTP were infused in 111 patients, 2.0 million units in 10 patients and 1.0 million in 3 cases within 30 minutes. CAG was performed 90 minutes after the initiation of thrombolytic therapy. Results Fifty two patients had coronary flow grade of TIMI 3 and 38 patients TIMI 2 90 minutes after the onset of thrombolytic therapy. The total patency rate of infarct related artery (IRA) was 72.6%. There was no significant difference ( P >0.05) in the patency rate of IRA of various locations. The patency rate of LAD was 71.6% (53/74), of RCA was 71.4% (30/42), of LCX was 85.7% (6/7) and effective patency in one patient with left main artery occlusion. Although there was a tendency that the earlier the thrombolytic therapy, the higher the patency rate of IRA patency, the results did not meet the statistically significant level (P>0.05). Using CAG as the gold standard, the clinical criteria used for evaluation of reperfusion rate had a sensitivity of 88%, specificity of 69% and accuracy of 83% in prediction of the reperfusion of IRA. Conclusion UK is effective and reliable in IV thrombolytic therapy of AMI. The clinical criteria used to predict reperfusion of IRA have a higher sensitivity and relatively lower specificity.

文摘BACKGROUND Endoscopic biliary stenting is a well-established palliative treatment for patients with unresectable distal malignant biliary obstruction(MBO). However, the main problem with stent placement is the relatively short duration of stent patency.Although self-expanding metal stents(SEMSs) have a longer patency period than plastic stents(PSs), the higher costs limit the wide use of SEMSs. A PS with an antireflux valve is an attractive idea to prolong stent patency, but no ideal design for an antireflux PS(ARPS) has been proposed. We developed a new ARPS with a "duckbilled" valve attached to the duodenal end of the stent.AIM To compare the patency of ARPSs with that of traditional PSs(TPSs) in patients with unresectable distal MBO.METHODS We conducted a single-center, prospective, randomized, controlled, double-blind study. This study was conducted at the West China Hospital of Sichuan University. Consecutive patients with extrahepatic MBO were enrolled prospectively. Eligible patients were randomly assigned to receive either an ARPS or a TPS. Patients were followed by clinic visits or telephone interviews every 1-2 mo until stent exchange, death, or the final study follow-up in October 2018. The primary outcome was the duration of stent patency. Secondary outcomes included the rate of technical success, the rate of clinical success,adverse events, and patient survival.RESULTS Between February 2016 and December 2017, 38 patients were randomly assigned to two groups, with 19 patients in each group, to receive ARPSs or TPSs. Stent insertion was technically successful in all patients. There were no significant differences between the two groups in the rates of clinical success or the rates of early or late adverse events(P = 0.660, 1.000, and 1.000, respectively). The median duration of stent patency in the ARPS group was 285 d [interquartile range(IQR),170], which was significantly longer than that in the TPS group(median, 130 d;IQR, 90, P = 0.005). No significant difference in patient survival was noted between the two groups(P = 0.900).CONCLUSION The new ARPS is safe and effective for the palliation of unresectable distal MBO,and has a significantly longer stent patency than a TPS.

文摘BACKGROUND Malignant obstructive jaundice(MOJ)is a common pathologic manifestation of malignant biliary obstruction.Recently,several clinical trials have explored the clinical effectiveness of intraluminal^(125)I seed-based brachytherapy for MOJ patients,and various outcomes have been reported.AIM To assess the efficacy and safety of percutaneous biliary stents with^(125)I seeds compared to conventional metal stents in patients with unresectable MOJ.METHODS A systematic search of English-language databases(PubMed,Embase,Cochrane Library,and Web of Science)was performed to identify studies published prior to June 2020 that compared stents with or without^(125)I seeds in the treatment of unresectable MOJ.The outcomes analyzed included primary outcomes(stent patency and overall survival)and secondary outcomes(complications and liver function parameters).RESULTS Six randomized controlled trials and four retrospective studies involving 875 patients were eligible for the analysis.Of the 875 included patients,404 were treated with^(125)I seed stents,while 471 were treated with conventional stents.Unadjusted pooled analysis demonstrated that compared to conventional stents,^(125)I seed stents extended the stent patency time[hazard ratio(HR)=0.36,95%confidence interval(CI)=0.28-0.45,P<0.0001]and overall survival period(HR=0.52,95%CI=0.42–0.64,P<0.00001).Subgroup analyses based on the type of^(125)I seed stent and type of study design showed consistent results.However,there were no significant differences in the occurrence of total complications[odds ratio(OR)=1.12,95%CI=0.75-1.67,P=0.57],hemobilia(OR=1.02,95%CI=0.45-2.3,P=0.96),pancreatitis(OR=1.79,95%CI=0.42-7.53,P=0.43),cholangitis(OR=1.13,95%CI=0.60-2.13,P=0.71),or pain(OR=0.67,95%CI=0.22-2,P=0.47).In addition,there were no reductions in the levels of serum indices,including total bilirubin[mean difference(MD)=10.96,95%CI=-3.56-25.49,P=0.14],direct bilirubin(MD=7.37,95%CI=-9.76-24.5,P=0.4),alanine aminotransferase(MD=7.52,95%CI=-0.71-15.74,P=0.07),and aspartate aminotransferase(MD=-4.77,95%CI=-19.98-10.44,P=0.54),after treatment.Publication bias was detected regarding the outcome overall survival;however,the conclusions were not changed after the adjustment.CONCLUSION Placement of stents combined with brachytherapy using^(125)I seeds contributes to a longer stent patency and higher overall survival than placement of conventional stents without extra complications or severe liver damage.Thus,it can be considered an effective and safe treatment for unresectable MOJ.
文摘AIM: To evaluate outcome of patients with Budd-Chiari syndrome after balloon angioplasty ± stenting or transjugular intrahepatic portosystemic shunt (TIPS). METHODS: Twenty five patients with Budd-Chiari syndrome admitted to Ain Shams University Hospitals, Tropical Medicine Department were included. Twelve patients (48%) with short segment occlusion were candidates for angioplasty; with stenting in ten cases and without stenting in two. Thirteen patients (52%) had Transjugular Intrahepatic Portosystemic Shunt. Patients were followed up for 12-32 mo. RESULTS: Patency rate in patients who underwent angioplasty ± stenting was 83.3% at one year and at end of follow up. The need of revision was 41.6% with one year survival of 100%, dropped to 91.6% at end of follow up. In patients who had Transjugular Intrahepatic Portosystemic Shunt, patency rate was 92.3% at one year, dropped to 84.6% at end of follow up. The need of revision was 38.4% with one year and end of follow up survival of 100%. Patients with patent shunts showed marked improvement compared to those with occluded shunts. CONCLUSION: Morbidity and mortality following angioplasty ± stenting and TIPS are low with satisfactory outcome. Proper patient selection and management of shunt dysfunction are crucial in improvement.
文摘Video capsule endoscopy (VCE) has evolved to become an important tool for the non-invasive examination of the small bowel, which hitherto had been relatively inaccessible to direct visualisation. VCE has been shown to play a role in monitoring the activity of small bowel Crohn’s disease and can be used to assess the response to anti-inflammatory treatment in Crohn’s disease. For those patients with Crohn’s disease who have undergone an intestinal resection, VCE has been assessed as a tool to detect post-operative recurrence. VCE may also aid in the reclassification of patients with a diagnosis of Inflammatory Bowel Disease Unclassified to Crohn’s disease. The evolution of colon capsule endoscopy (CCE) has expanded the application of this technology further. The use of CCE to assess the activity of ulcerative colitis has been described. This advance in capsule technology has also fuelled interest in its potential role as a minimally invasive tool to assess the whole of GI tract opening the possibility of its use for the panenteric assessment of Crohn’s disease. VCE is a safe procedure. However, the risk of a retained capsule is higher in patients with suspected or confirmed Crohn’s disease compared with patients having VCE examination for other indications. A retained video capsule is rare after successful passage of a patency capsule which may be utilised to pre-screen patients undergoing VCE. This paper describes the use of VCE in the assessment of inflammatory bowel disease.
