Clinical characteristics of acute non-varicose upper gastrointestinal bleeding and the effect of endoscopic hemostasis

BACKGROUND Acute non-variceal upper gastrointestinal bleeding(ANVUGIB)constitutes a prevalent emergency within Gastroenterology,encompassing 80%-90%of all gastrointestinal hemorrhage incidents.This condition is distinguished by its abrupt onset,swift progression,and notably elevated mortality rate.AIM To gather clinical data from patients with ANVUGIB at our hospital in order to elucidate the clinical characteristics specific to our institution and analyze the therapeutic effectiveness of endoscopic hemostasis.METHODS We retrospectively retrieved the records of 532 patients diagnosed with ANVUGIB by endoscopy at our hospital between March 2021 and March 2023,utilizing our medical record system.Data pertaining to general patient information,etiological factors,disease outcomes,and other relevant variables were meticulously collected and analyzed.RESULTS Among the 532 patients diagnosed with ANVUGIB,the male-to-female ratio was 2.91:1,with a higher prevalence among males.Notably,43.6%of patients presented with black stool as their primary complaint,while 27.4%had hematemesis as their initial symptom.Upon admission,17%of patients exhibited both hematemesis and black stool,while most ANVUGIB patients primarily complained of overt gastrointestinal bleeding.Urgent routine blood examinations at admission revealed that 75.8%of patients had anemia,with 63.4%experiencing moderate to severe anemia,and 1.5%having extremely severe anemia(hemoglobin<30 g/L).With regard to etiology,53.2%of patients experienced bleeding without a definitive trigger,24.2%had a history of using gastric mucosa-irritating medications,24.2%developed bleeding after alcohol consumption,2.8%attributed it to improper diet,1.7%to emotional excitement,and 2.3%to fatigue preceding the bleeding episode.Drug-induced ANVUGIB was more prevalent in the elderly than middle-aged and young individuals,while bleeding due to alcohol consumption showed the opposite trend.Additionally,diet-related bleeding was more common among the young age group compared to the middle-aged group.Gastrointestinal endoscopy identified peptic ulcers as the most frequent cause of ANVUGIB(73.3%),followed by gastrointestinal malignancies(10.9%),acute gastric mucous lesions(9.8%),and androgenic upper gastrointestinal bleeding(1.5%)among inpatients with ANVUGIB.Of the 532 patients with gastrointestinal bleeding,68 underwent endoscopic hemostasis,resulting in an endoscopic treatment rate of 12.8%,with a high immediate hemostasis success rate of 94.1%.

Efficacy and safety of over-the-scope-clips in the therapy of acute nonvariceal upper gastrointestinal bleeding:Meta-analysis

BACKGROUND Acute nonvariceal upper gastrointestinal bleeding(ANVUGIB)is a frequent lifethreatening acute condition in gastroenterology associated with high morbidity and mortality.Over-the-scope-clip(OTSC)is a new endoscopic hemostasis technique,which is being used in ANVUGIB and is more effective.AIM To summarize and analyze the effects of the OTSC in prevention of recurrent bleeding,clinical success rate,procedure time,hospital stay,and adverse events in the treatment of ANVUGIB,to evaluate whether OTSC can replace standard endoscopic therapy as a new generation of treatment for ANVUGIB.METHODS The literature related to OTSC and standard therapy for ANVUGIB published before January 2023 was searched in PubMed,Web of Science,EMBASE,Cochrane,Google,and CNKI databases.Changes in recurrent bleeding(7 or 30 days),clinical results(clinical success rate,conversion rate to surgery,mortality),therapy time(procedure time,hospital stay),and adverse events in the OTSC intervention group were summarized and analyzed,and the MD or OR of 95%CI is calculated by Review Manager 5.3.RESULTS This meta-analysis involved 11 studies with 1266 patients.Total risk of bias was moderate-to-high.For patients in the OTSC group,7-and 30-days recurrent bleeding rates,as well as procedure time,hospital stay,and intensive care unit stay,were greatly inhibited.OTSC could significantly improve the clinical success rate of ANVUGIB.OTSC therapy did not cause serious adverse and was effective in reducing patient mortality.CONCLUSION OTSC may provide more rapid and sustained hemostasis,and thus,promote recovery and reduce mortality in patients with ANVUGIB.In addition,the safety of OTSC is assured.

The effect of prophylactic antibiotics in acute upper gastrointestinal bleeding patients in the emergency department

BACKGROUND: Currently, prophylactic antibiotics are recommended only for cirrhotic patients with acute upper gastrointestinal bleeding(AUGIB);however, the benefit for other AUGIB patients remains undetermined. We aimed to compare the clinical outcomes between patients with AUGIB with and without prophylactic antibiotics to identify the population that requires this therapy.METHODS: Patients with AUGIB admitted between 1st January 2019 and 31st December 2021 in the Emergency Department of Peking Union Medical College Hospital were enrolled. Patients were divided into the antibiotic and non-antibiotic groups. The primary outcome was in-hospital mortality, and the secondary outcome was the onset of new infection. The risk factors for mortality and infection were analyzed, and stratification analysis of prophylactic antibiotics was performed. Continuous data were analyzed using the t-test or nonparametric rank sum test, and categorical data were analyzed using the Chi-square test or Fisher's exact test. Indicators with significant differences between the groups were included for logistic regression analysis. A P-value <0.05 was considered statistically significant. RESULTS: A total of 392 individuals were included, among them, 281 patients received prophylactic antibiotics, and 111 patients did not receive prophylactic antibiotics. The mortality rates were significantly lower in the antibiotic group than in the non-antibiotics group(6.41% vs. 17.12%, P=0.001). The risk factors for infection were varicose veins(P=0.045) and endotracheal intubation(P=0.005) in the prophylactic antibiotic group, and endoscopic treatment(P=0.010) in the non-prophylactic antibiotic group. Stratified analyses showed that patients with age ≥ 65 years, endotracheal intubation, endoscopic treatment, and AUGIB of variceal etiologies benefited from prophylactic antibiotics.CONCLUSION: AUGIB patients may benefit from prophylactic antibiotics to decrease mortality, especially those aged ≥ 65 years and those with endotracheal intubation, endoscopic treatment, and variceal etiologies.

Predictive utility of the Rockall scoring system in patients suffering from acute nonvariceal upper gastrointestinal hemorrhage

BACKGROUND Acute non-variceal upper gastrointestinal bleeding(ANVUGIB)represents a sig-nificant clinical challenge due to its unpredictability and potentially severe out-comes.The Rockall risk score has emerged as a critical tool for prognostic asse-ssment in patients with ANVUGIB,aiding in the prediction of rebleeding and mo-rtality.However,its applicability and accuracy in the Chinese population remain understudied.AIM To assess the prognostic value of the Rockall risk score in a Chinese cohort of patients with ANVUGIB.METHODS A retrospective analysis of 168 ANVUGIB patients’medical records was condu-cted.The study employed statistical tests,including the t-test,χ^(2) test,spearman correlation,and receiver operating characteristic(ROC)analysis,to assess the re-lationship between the Rockall score and clinical outcomes,specifically focusing on rebleeding events within 3 months post-assessment.RESULTS Significant associations were found between the Rockall score and various clinical outcomes.High Rockall scores were significantly associated with rebleeding events(r=0.735,R2=0.541,P<0.001)and strongly positively correlated with adverse outcomes.Low hemoglobin levels(t=2.843,P=0.005),high international normalized ratio(t=3.710,P<0.001),active bleeding during endoscopy(χ^(2)=7.950,P=0.005),large ulcer size(t=6.348,P<0.001),and requiring blood transfusion(χ^(2)=6.381,P=0.012)were all significantly associated with rebleeding events.Furthermore,differences in treatment and management strategies were identified between patients with and without rebleeding events.ROC analysis indicated the excellent discriminative power(sensitivity:0.914;specificity:0.816;area under the curve:0.933;Youden index:0.730)of the Rockall score in predicting rebleeding events within 3 months.CONCLUSION This study provides valuable insights into the prognostic value of the Rockall risk score for ANVUGIB in the Chinese population.The results underscore the potential of the Rockall score as an effective tool for risk strati-fication and prognostication,with implications for guiding risk-appropriate management strategies and optimizing care for patients with ANVUGIB.

A Case of Acute Upper Gastrointestinal Bleeding in Liver Cirrhosis Complicated by Acute Cerebral Infarction and Acute Myelitis

Background: Acute upper gastrointestinal bleeding in liver cirrhosis combined with acute cerebral infarction is uncommon in clinical work, and then combined with acute myelitis is even rarer and more complex, which poses a greater challenge to clinical diagnosis and treatment. This paper reports a case of acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis, which be hoped to provide a reference for clinical work. Methods: We retrospectively evaluated the clinical information of a 68-year-old female admitted to the Digestive Medical Department with acute gastrointestinal bleeding and appeared limb movement disorder on the third day. Results: The patient was eventually diagnosed with acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis. Conclusions: When patients with liver cirrhosis have abnormal neurological symptoms, in addition to liver cirrhosis-related complications, doctors need to consider cerebrovascular diseases and myelitis.

Rockall score in predicting outcomes of elderly patients with acute upper gastrointestinal bleeding

AIM: To validate the clinical Rockall score in predicting outcomes (rebleeding, surgery and mortality) in elderly patients with acute upper gastrointestinal bleeding (AUGIB). METHODS: A retrospective analysis was undertaken in 341 patients admitted to the emergency room and Intensive Care Unit of Xuanwu Hospital of Capital Medical University with non-variceal upper gastrointestinal bleeding. The Rockall scores were calculated, and the association between clinical Rockall scores and patient outcomes (rebleeding, surgery and mortality) was assessed. Based on the Rockall scores, patients were divided into three risk categories: low risk ≤ 3, moderate risk 3-4, high risk ≥ 4, and the percentages of rebleeding/death/surgery in each risk category were compared. The area under the receiver operating characteristic (ROC) curve was calculated to assess the validity of the Rockall system in predicting rebleeding, surgery and mortality of patients with AUGIB. RESULTS: A positive linear correlation between clinical Rockall scores and patient outcomes in terms of rebleeding, surgery and mortality was observed (r =0.962, 0.955 and 0.946, respectively, P = 0.001). High clinical Rockall scores > 3 were associated with adverse outcomes (rebleeding, surgery and death). There was a significant correlation between high Rockall scores and the occurrence of rebleeding, surgery and mortality in the entire patient population (χ 2 = 49.29, 23.10 and 27.64, respectively, P = 0.001). For rebleeding, the area under the ROC curve was 0.788 (95%CI: 0.726-0.849, P = 0.001); For surgery, the area under the ROC curve was 0.752 (95%CI: 0.679-0.825, P = 0.001) and for mortality, the area under the ROC curve was 0.787 (95%CI: 0.716-0.859, P = 0.001). CONCLUSION: The Rockall score is clinically useful, rapid and accurate in predicting rebleeding, surgery and mortality outcomes in elderly patients with AUGIB.

Acute upper gastrointestinal bleeding in octοgenarians:Clinical outcome and factors related to mortality

AIM: To evaluate the aetiology, clinical outcome and factors related to mortality of acute upper gastrointestinal bleeding (AUGIB) in octogenarians. METHODS: We reviewed the records of all patients over 65 years old who were hospitalised with AUGIB in two hospitals from January 2006 to December of 2006. Patients were divided into two groups: Group A (65-80 years old) and Group B (> 80 years old). RESULTS: Four hundred and sixteen patients over 65 years of age were hospitalized because of AUGIB. Group A included 269 patients and Group B 147 patients. Co-morbidity was more common in octogenarians (P = 0.04). The main cause of bleeding was peptic ulcer in both groups. Rebleeding and emergency surgery were uncommon in octogenarians and not different from those in younger patients. In-hospital complications were more common in octogenarians (P = 0.05) and more patients died in the group of octogenarians compared to the younger age group (P = 0.02). Inability to perform endoscopic examination (P = 0.002), presence of high risk for rebleeding stigmata (P = 0.004), urea on admission (P = 0.036), rebleeding (P = 0.004) and presenceof severe co-morbidity (P < 0.0001) were related to mortality. In multivariate analysis, only the presence of severe co-morbidity was independently related to mortality (P = 0.032). CONCLUSION: While rebleeding and emergency surgery rates are relatively low in octogenarians with AUGIB, the presence of severe co-morbidity is the main factor of adverse outcome.

A Nomogram Model for Predicting Type-2 Myocardial Infarction Induced by Acute Upper Gastrointestinal Bleeding

Objective To examine the independent risk factors of type-2 myocardial infarction(T2MI)elicited by acute upper gastrointestinal bleeding(AUGIB),and to establish a nomogram model for the prediction of AUGIB-induced T2MI.Methods A nomogram model was established on the basis of a retrospective study that involved 533 patients who suffered from AUGIB in the Department of Critical Care Medicine(CCM)or Emergency Intensive Care Unit(EICU)of Renmin Hospital of Wuhan University,Wuhan,China,from January 2017 to December 2020.The predictive accuracy and discriminative power of the nomogram were initially evaluated by internal validation,which involved drawing the receiver operating characteristic(ROC)curve,calculating the area under the curve(AUC),plotting the calibration curve derived from 1000 resampled bootstrap data sets,and computing the root mean square error(RMSE).The predictive ability of the nomogram was further validated through the prospective and multicenter study conducted by the investigators,which enrolled 240 AUGIB patients[including 88 cases from Renmin Hospital of Wuhan University,73 cases from Qilu Hospital of Shandong University(Qingdao),and 79 cases from Northern Jiangsu People’s Hospital)],who were admitted to the Department of CCM or EICU,from February 2021 to July 2021.Results Among the 533 patients in the training cohort,78(14.6%)patients were assigned to the T2MI group and 455(85.4%)patients were assigned to the non-T2MI group.The multivariate analysis revealed that age>65,hemorrhagic shock,cerebral stroke,heart failure,chronic kidney disease,increased blood urea nitrogen,decreased hematocrit,and elevated D-Dimer were independent risk factors for AUGIB-induced T2MI.All these factors were incorporated into the nomogram model.The AUC for the nomogram for predicting T2MI was 0.829(95%CI,0.783-0.875)in the internal validation cohort and 0.848(95%CI,0.794-0.902)in the external validation cohort.The calibration curve for the risk of T2MI exhibited good consistency between the prediction by the nomogram and the actual clinical observation in both the internal validation(RMSE=0.016)and external validation(RMSE=0.020).Conclusion The nomogram was proven to be a useful tool for the risk stratification of T2MI in AUGIB patients,and is helpful for the early identification of AUGIB patients who are prone to T2MI for early intervention,especially in emergency departments and intensive care units.

A Nomogram Model for Prediction of Mortality Risk of Patients with Dangerous Upper Gastrointestinal Bleeding:A Two-center Retrospective Study

Objective:This study aimed to establish a nomogram model to predict the mortality risk of patients with dangerous upper gastrointestinal bleeding(DUGIB),and identify high-risk patients who require emergent therapy.Methods:From January 2020 to April 2022,the clinical data of 256 DUGIB patients who received treatments in the intensive care unit(ICU)were retrospectively collected from Renmin Hospital of Wuhan University(n=179)and the Eastern Campus of Renmin Hospital of Wuhan University(n=77).The 179 patients were treated as the training cohort,and 77 patients as the validation cohort.Logistic regression analysis was used to calculate the independent risk factors,and R packages were used to construct the nomogram model.The prediction accuracy and identification ability were evaluated by the receiver operating characteristic(ROC)curve,C index and calibration curve.The nomogram model was also simultaneously externally validated.Decision curve analysis(DCA)was then used to demonstrate the clinical value of the model.Results:Logistic regression analysis showed that hematemesis,urea nitrogen level,emergency endoscopy,AIMS65,Glasgow Blatchford score and Rockall score were all independent risk factors for DUGIB.The ROC curve analysis indicated the area under curve(AUC)of the training cohort was 0.980(95%CI:0.962-0.997),while the AUC of the validation cohort was 0.790(95%CI:0.685-0.895).The calibration curves were tested for Hosmer-Lemeshow goodness of fit for both training and validation cohorts(P=0.778,P=0.516).Conclusion:The developed nomogram is an effective tool for risk stratification,early identification and intervention for DUGIB patients.

Acute upper gastrointestinal bleeding caused by esophageal right bronchial artery fistula:A case report

BACKGROUND Fistula between the esophagus and bronchial artery is an extremely rare and potentially life-threatening cause of acute upper gastrointestinal bleeding.Here,we report a case of fistula formation between the esophagus and a nonaneurysmal right bronchial artery(RBA).CASE SUMMARY An 80-year-old woman with previous left pneumonectomy and recent placement of an uncovered self-expandable metallic stent for esophageal adenocarcinoma was admitted due to hematemesis.Emergent computed tomography showed indirect signs of fistulization between the esophagus and a nonaneurysmal RBA,in the absence of active bleeding.Endoscopy revealed the esophageal stent correctly placed and a moderate amount of red blood within the stomach,in the absence of active bleeding or tumor ingrowth/overgrowth.After prompt multidisciplinary evaluation,a step-up approach was planned.The bleeding was successfully controlled by esophageal restenting followed by RBA embolization.No signs of rebleeding were observed and the patient was discharged home with stable hemoglobin level on postoperative day 7.CONCLUSION This was a previously unreported case of an esophageal RBA fistula successfully managed by esophageal restenting followed by RBA embolization.

Treatment of severe upper gastrointestinal bleeding caused by Mallory-Weiss syndrome after primary coronary intervention for acute inferior wall myocardial infarction: A case report

BACKGROUND Upper gastrointestinal bleeding(UGIB) after an acute myocardial infarction(AMI) is not an uncommon complication. Acute UGIB caused by Mallory-Weiss syndrome(MWS) is usually a dire situation with massive bleeding and hemodynamic instability. Acute UGIB caused by MWS after an AMI has not been previously reported.CASE SUMMARY A 57-year-old man with acute inferior wall ST elevation myocardial infarction underwent a primary coronary intervention of the acutely occluded right coronary artery. Six hours after the intervention, the patient had a severe UGIB,followed by vomiting. His hemoglobin level dropped from 15.3 g/d L to 9.7 g/d L. In addition to blood transfusion and a gastric acid inhibition treatment,early endoscopy was employed and MWS was diagnosed. Bleeding was stopped by endoscopic placement of titanium clips.CONCLUSION Bleeding complications after stent implantation can pose a dilemma. MWS is a rare but severe cause of acute UGIB after an AMI that requires an early endoscopic diagnosis and a hemoclip intervention to stop bleeding.

Massive bleeding from gastric submucosal arterial collaterals secondary to splenic artery thrombosis: A case report

BACKGROUND Gastric submucosal arterial collaterals(GSAC)secondary to splenic artery occlusion is an extraordinary rare and potentially life-threatening cause of acute upper gastrointestinal bleeding.Here,we report a case of massive bleeding from GSAC successfully treated by means of a multidisciplinary minimally invasive approach.CASE SUMMARY A 60-year-old non-cirrhotic gentleman with a history of arterial hypertension was admitted due to hematemesis.Emergent esophagogastroduodenoscopy revealed pulsating and tortuous varicose shaped submucosal vessels in the gastric fundus along with a small erosion overlying one of the vessels.In order to characterize the fundic lesion,pre-operative emergent computed tomography-angiography was performed showing splenic artery thrombosis(SAT)and tortuous arterial structures arising from the left gastric artery and the left gastroepiploic artery in the gastric fundus.GSAC was successfully treated by means of a minimally invasive step-up approach consisting in endoscopic clipping followed by transcatheter arterial embolization(TAE).CONCLUSION This was a previously unreported case of bleeding GSAC secondary to SAT successfully managed by means of a multidisciplinary minimally invasive approach consisting in endoscopic clipping for the luminal bleeding control followed by elective TAE for the definitive treatment.

急性上消化道出血患者预后预测模型的构建与验证

目的:分析急性上消化道出血(Acute Upper Gastrointestinal Bleeding,AUGIB)住院患者不良预后风险因素,构建AUGIB患者短期不良预后风险预测模型,为AUGIB管理及风险分层提供参考。方法:回顾性分析由2016年9月至2022年6月来自广州医科大学附属第二医院由急诊入院的AUGIB患者,按7∶3分为训练集及验证集。通过Lasso回归、多因素Logistic回归构建预测模型并进行预测能效评估。结果:消化系统恶性肿瘤、休克指数>1、GCS评分<14分、血浆白蛋白<24 g/L、血钙<1.95 mmol/L和血肌酐>103μmol/L与AUGIB患者预后不良相关。使用上述变量组成的评分量表,与GBS评分在预测不良预后上有统计学差异(0.826 vs 0.700,P=0.002),与AIMS 65评分无统计学差异(0.826 vs 0.768,P=0.260)。结论:由消化系统恶性肿瘤、休克指数>1、GCS评分<14分、血浆白蛋白<24 g/L、血钙<1.95 mmol/L以及血肌酐>103μmol/L五个变量构建的预测模型对于AUGIB患者不良预后具有良好的预测能效,其预测价值与AIMS 65评分相当,可能优于GBS评分。

基于白蛋白-胆红素指数构建肝硬化并发急性上消化道出血的预测模型

目的:探讨白蛋白-胆红素(ALBI)指数对肝硬化患者并发急性上消化道出血的预测价值,并建立相关预测模型。方法:选取2019年12月至2022年12月收治的肝硬化患者并发急性上消化道出血作为研究对象,收集患者临床资料,采用ROC曲线评估ALBI指数的预测价值,并计算最佳截断值。采用单因素和多因素Logistic回归分析肝硬化患者并发急性上消化道出血的影响因素,并据此建立列线图模型。结果:ALBI指数预测肝硬化患者并发急性上消化道出血的ROC曲线下面积为0.764(95%CI=0.693~0.835)。病程较长、腹水、Ca<2.2 mmol/L、PT≥16 s、PLT<100×109/L和ALBI指数≥-1.87是肝硬化患者并发急性上消化道出血的独立危险因素(P<0.05)。据此建立预测肝硬化患者并发急性上消化道出血风险的列线图模型,模型验证结果显示一致性指数(C-index)为0.854,校准曲线趋近于理想曲线,ROC曲线的AUC为0.851(95%CI=0.823~0.879),在5%~96%预测范围内模型净获益。结论:ALBI指数对肝硬化患者并发急性上消化道出血具有较高的预测价值,基于ALBI指数构建的列线图模型能够有效预测该类患者的风险。
