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.展开更多

In this review, we have appraised the role of early TIPSS, patient selection anddiscussed future directions in the management of patients with AVB.展开更多

They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered.RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience.Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy.On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy.CONCLUSION: Endoscopist's experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis.展开更多

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.展开更多

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.展开更多

文摘BACKGROUND Early transjugular intrahepatic portosystemic shunts(TIPS)is a therapeutic option for acute variceal bleeding(AVB),offering a low risk of rebleeding.However,the long-term outcomes of early TIPS remain unclear.AIM To evaluate the long-term outcomes for early TIPS compared with standard treatment in patients with cirrhosis and AVB.METHODS We retrospectively analyzed the clinical data of patients with AVB who underwent early TIPS or standard treatment between January 2014 and December 2023.The primary outcome was overall survival(OS).RESULTS A total of 37 patients with AVB underwent early TIPS,while 65 patients received standard treatment.Compared with the standard treatment group,the rates of uncontrolled bleeding or rebleeding in the early TIPS group were significantly lower(10.8%vs 50.8%,P<0.001).Over a median follow-up of 46 months,no statistically significant differences were observed in terms of OS(P=0.507).The presence of comorbidities was identified as an independent predictor of OS(adjusted hazard ratio=3.81;95%confidence interval:1.16-12.46).Notably,new or worsening ascites occurred less frequently in the early TIPS group(13.5%vs 38.5%,P=0.008).There was no significant difference in the rate of overt hepatic encephalopathy between the two groups(45.9%vs 36.9%,P=0.372).CONCLUSION While early TIPS is not associated with a long-term survival benefit compared with standard treatment for AVB,it is associated with reduced risks of rebleeding and ascites.

文摘BACKGROUND Acute variceal bleeding(AVB)represents a life-threatening complication in hepatocellular carcinoma(HCC)patients undergoing systemic therapy,mainly including immune checkpoint inhibitors(ICIs)and antivascular drugs used alone or in combination.The pathogenesis of AVB in this population may involve tumor-related factors,treatment-induced effects,or progression of underlying portal hypertension.Identifying high-risk factors for AVB is crucial for the management of this patient population.AIM To develop and validate a risk prediction model for AVB occurrence in cirrhotic HCC patients receiving ICI-based systemic therapy.METHODS This retrospective study analyzed 286 HCC patients(2021-2022)receiving ICIs(mono-/combination therapy),randomly split into training(n=184)and validation(n=102)cohorts.In the training cohort,bleeding vs nonbleeding groups were compared for general information,etiological data,laboratory indicators,tumor staging,systemic treatment drugs,variceal bleeding history,and endoscopic treatment history.Risk factors for AVB were identified and used to establish a logistic regression model for predicting bleeding,which was further validated in the validation cohort.RESULTS The bleeding group had significantly higher proportions of patients with platelet count≥100×10^(9)/L,alphafetoprotein≥400 ng/mL,tumor diameter≥5 cm,portal vein tumor thrombosis,ascites,bleeding history,prior endoscopic treatment,albumin-bilirubin grade level 2-3,fibrosis-4 index(FIB-4)≥4.57,and prognostic nutritional index<45 compared to the non-bleeding group.Multivariate analysis identified tumor diameter≥5 cm,portal vein thrombosis,bleeding history,and elevated FIB-4 as independent risk factors for bleeding(P<0.05).A predictive model based on these factors showed good discrimination,with area under the receiver operating characteristic curve values of 0.861(training)and 0.816(validation).CONCLUSION A history of pre-ICI bleeding significantly increases recurrent bleeding risk,necessitating close monitoring.The FIB-4 fibrosis model,combined with tumor features,can also serve as a predictive factor for bleeding.

文摘BACKGROUND Acute variceal bleeding(AVB)in patients with cirrhosis remains life-threatening;moreover,the current risk stratification methods have certain limitations.Rebleeding and mortality after AVB remain major challenges.Although preemptive transjugular intrahepatic portosystemic shunt(p-TIPS)can improve outcomes,not all patients benefit equally.Accurate risk stratification is needed to guide treatment decisions and identify those most likely to benefit from p-TIPS.AIM To develop an artificial intelligence(AI)-driven model to guide AVB treatment decisions,and identify candidates eligible for p-TIPS.METHODS Patients with cirrhosis and AVB,from two multicenter retrospective cohorts in China,who received endoscopic variceal ligation plus pharmacotherapy(n=1227)or p-TIPS(n=1863)were included.Baseline data within 24 hours of hospital admission were obtained.The AI-AVB model,based on the six-week failure and one-year mortality rates,was developed to predict treatment efficacy and compared with standard risk scores.Outcomes and adverse events of the treatments were compared across the high-and low-risk subgroups stratified using the AI-AVB model.RESULTS The AI-AVB model demonstrated superior predictive performance compared to traditional risk stratification methods.In the internal validation cohort,the model achieved an area under the curve(AUC)of 0.842 for predicting six-week treatment failure and 0.954 for one-year mortality.In the external validation cohort,the AUCs were 0.814 and 0.889,respectively.The model effectively identified patients at high risk of first-line treatment failure who may benefit from aggressive interventions such as p-TIPS.In contrast,advancing the treatment strategy for low-risk patients did not notably improve the short-term prognosis.CONCLUSION The AI-AVB model can predict treatment outcomes,stratify the failure risk in cirrhotic patients with AVB,aid in clinical decisions,identify p-TIPS beneficiaries,and optimize personalized treatment strategies.

文摘BACKGROUND Transjugular intrahepatic portosystemic shunt(TIPS)is an effective intervention for managing complications of portal hypertension,particularly acute variceal bleeding(AVB).While effective in reducing portal pressure and preventing rebleeding,TIPS is associated with a considerable risk of overt hepatic encephalopathy(OHE),a complication that significantly elevates mortality rates.AIM To develop a machine learning(ML)model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.METHODS This retrospective single-center study included 218 patients with AVB who underwent TIPS.The dataset was divided into training(70%)and testing(30%)sets.Critical features were identified using embedded methods and recursive feature elimination.Three ML algorithms-random forest,extreme gradient boosting,and logistic regression-were validated via 10-fold cross-validation.SHapley Additive exPlanations analysis was employed to interpret the model’s predictions.Survival analysis was conducted using Kaplan-Meier curves and stepwise Cox regression analysis to compare overall survival(OS)between patients with and without OHE.RESULTS The median OS of the study cohort was 47.83±22.95 months.Among the models evaluated,logistic regression demonstrated the highest performance with an area under the curve(AUC)of 0.825.Key predictors identified were Child-Pugh score,age,and portal vein thrombosis.Kaplan-Meier analysis revealed that patients without OHE had a significantly longer OS(P=0.005).The 5-year survival rate was 78.4%,with an OHE incidence of 15.1%.Both actual OHE status and predicted OHE value were significant predictors in each Cox model,with model-predicted OHE achieving an AUC of 88.1 in survival prediction.CONCLUSION The ML model accurately predicts post-TIPS OHE and outperforms traditional models,supporting its use in improving outcomes in patients with AVB.
文摘Objective:To analyze the effect of optimizing the emergency nursing process on the nursing effect of patients with acute upper gastrointestinal bleeding(AUGB)in the emergency department.Methods:100 cases(Group A)were randomly selected from AUGB patients who had undergone the routine emergency care process in the emergency department from January 2022 to December 2022,and 100 cases(Group B)were randomly selected from AUGB patients who had undergone the optimized emergency care process in the emergency department from January 2023 to December 2023.The nursing effects of the two groups were compared.Results:clinical indicators that include the emergency response time,time to open the infusion channel,time from diagnosis to specialty treatment,hospitalization time,resuscitation success rate,rebleeding rate,nursing satisfaction score,post-care SAS score,and SF-36 score in Group B were better than those in Group A(P<0.05).Conclusion:Optimization of the emergency care process for AUGB patients in the emergency department can improve the efficiency and success rate of resuscitation,reduce the risk of rebleeding,improve the mood and quality of life of patients,and make the patients more satisfied with the nursing service.

文摘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%.
文摘BACKGROUND Acute upper gastrointestinal bleeding is a common medical emergency that has a 10%hospital mortality rate.According to the etiology,this disease can be divided into acute varicose veins and nonvaricose veins.Bleeding from esophageal varices is a life-threatening complication of portal hypertension.Portal hypertension is a clinical syndrome defined as a portal venous pressure that exceeds 10 mmHg.Cirrhosis is the most common cause of portal hypertension,and thrombosis of the portal system not associated with liver cirrhosis is the second most common cause of portal hypertension in the Western world.Primary myeloproliferative disorders are the main cause of portal venous thrombosis,and somatic mutations in the Janus kinase 2 gene(JAK2 V617F)can be found in approximately 90% of polycythemia vera,50% of essential thrombocyrosis and 50% of primary myelofibrosis.CASE SUMMARY We present a rare case of primary myelofibrosis with gastrointestinal bleeding as the primary manifestation that presented as portal-superior-splenic mesenteric vein thrombosis.Peripheral blood tests revealed the presence of the JAK2 V617F mutation.Bone marrow biopsy ultimately confirmed the diagnosis of myelofibrosis(MF-2 grade).CONCLUSION In patients with acute esophageal variceal bleeding due to portal hypertension and vein thrombosis without cirrhosis,the possibility of myeloproliferative neoplasms should be considered,and the JAK2 mutation test should be performed.
文摘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.
文摘Antibiotic prophylaxis in patients with cirrhosis and acute variceal bleeding is part of the standard of care according to most clinical guidelines.However,with recent evidence arguing against antibiotic prophylaxis,the role of this intervention has become less clear.
文摘Hemostatic radiotherapy is a non-invasive treatment for bleeding gastrointestinal(GI)tumors,promoting tumor shrinkage,blood supply reduction,and fibrotic tissue formation.It is effective in cases where traditional interventions are insufficient or contraindicated and can prevent recurrent bleeding in patients with GI bleeding histories.Hypofractionation schedules are also effective for tumor control and patient compliance.
文摘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.
文摘Hepatic venous pressure gradient(HVPG)is an independent predictor of variceal rebleeding in patients with cirrhosis.After pharmacological and/or endoscopic therapy,the use of a transjugular intrahepatic portosystemic shunt(TIPS)may be necessary in HVPG non-responders,but not in responders.Thus,HVPG measurement may be incorporated into the treatment algorithm for acute variceal bleeding,which further identifies the candidates that should undergo early insertion of TIPS or maintain the traditional pharmacological and/or endoscopic therapy.The potential benefits are to reduce the cost and prevent TIPS-related complications.
文摘Variceal bleeding is a serious complication of cirrhosis and portal hypertension.Despite the improvement in management of acute variceal bleed(AVB),it still carries significant mortality.Portal pressure is the main driver of variceal bleeding and also a main predictor of decompensation.Reduction in portal pressure has been the mainstay of management of variceal bleeding.Transjugular intrahepatic porto-systemic stent shunt(TIPSS)is a very effective modality in reducing the portal hypertension and thereby,controlling portal hypertensive bleeding.However,its use in refractory bleeding(rescue/salvage TIPSS)is still associated with high mortality.“Early”use of TIPSS as a“pre-emptive strategy”in patients with AVB at high risk of failure of treatment has shown to be superior to standard treatment in several studies.While patients with Child C cirrhosis(up to 13 points)clearly benefit from early-TIPSS strategy,it’s role in less severe liver disease(Child B)and more severe disease(Child C>13 points)remains less clear.Moreover,standard of care has improved in the last decade leading to improved 1-year survival in high-risk patients with AVB as compared to earlier“early”TIPSS studies.Lastly in the real world,only a minority of patients with AVB fulfil the stringent criteria for early TIPSS.Therefore,there is unmet need to explore role of early TIPSS in management of AVB in well-designed prospective studies. In this review, we have appraised the role of early TIPSS, patient selection anddiscussed future directions in the management of patients with AVB.
文摘AIM: To prospectively assess the impact of time of endoscopy and endoscopist's experience on the outcome of non-variceal acute upper gastrointestinal (GI) bleeding patients in a large teaching hospital.METHODS: All patients admitted for non-variceal acute upper GI bleeding for over a 2-year period were potentially eligible for this study. They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered.RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience.Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy.On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy.CONCLUSION: Endoscopist's experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis.

文摘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.
文摘BACKGROUND Acute severe variceal bleeding(AVB)refractory to medical and endoscopic therapy is infrequent but associated with high mortality.Historical cohort studies from 1970-1980s no longer represent the current population as balloon tamponade is no longer first-line therapy for variceal bleeding;treatments including vasoactive therapies,intravenous antibiotics,endoscopic variceal band ligation are routinely used,and there is improved access to definitive treatments including transjugular intrahepatic portosystemic shunts.However,only a few studies from the current era exist to describe the practice of balloon tamponade,its outcomes,and predictors with a requirement for further updated information.AIM To describe current management of AVB requiring balloon tamponade and identify the outcomes and predictors of mortality,re-bleeding and complications.METHODS A retrospective multi-centre cohort study of 80 adult patients across two large tertiary health networks from 2008 to 2019 in Australia who underwent balloon tamponade using a Sengstaken-Blakemore tube(SBT)were included for analysis.Patients were identified using coding for balloon tamponade.The primary outcome of this study was all-cause mortality at 6 wk after the index AVB.Secondary outcomes included re-bleeding during hospitalisation and complications of balloon tamponade.Predictors of these outcomes were determined using univariate and multivariate binomial regression.RESULTS The all-cause mortality rates during admission and at 6-,26-and 52 wk were 48.8%,51.2%and 53.8%,respectively.Primary haemostasis was achieved in 91.3%and re-bleeding during hospitalisation occurred in 34.2%.Independent predictors of 6 wk mortality on multivariate analysis included the Model for Endstage Liver disease(MELD)score(OR 1.21,95%CI 1.06-1.41,P=0.006),advanced hepatocellular carcinoma(OR 11.51,95%CI 1.61-82.20,P=0.015)and re-bleeding(OR 13.06,95%CI 3.06-55.71,P<0.001).There were no relevant predictors of re-bleeding but a large proportion in which this occurred did not survive 6 wk(76.0%vs 24%).Although mucosal trauma was the most common documented complication after SBT insertion(89.5%),serious complications from SBT insertion were uncommon(6.3%)and included 1 patient who died from oesophageal perforation.CONCLUSION In refractory AVB,balloon tamponade salvage therapy is associated with high rates of primary haemostasis with low rates of serious complications.Re-bleeding and mortality however,remain high.
文摘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.
文摘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.

文摘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.
