文摘BACKGROUND Rebleeding after recovery from esophagogastric variceal bleeding(EGVB)is a severe complication that is associated with high rates of both incidence and mortality.Despite its clinical importance,recognized prognostic models that can effectively predict esophagogastric variceal rebleeding in patients with liver cirrhosis are lacking.AIM To construct and externally validate a reliable prognostic model for predicting the occurrence of esophagogastric variceal rebleeding.METHODS This study included 477 EGVB patients across 2 cohorts:The derivation cohort(n=322)and the validation cohort(n=155).The primary outcome was rebleeding events within 1 year.The least absolute shrinkage and selection operator was applied for predictor selection,and multivariate Cox regression analysis was used to construct the prognostic model.Internal validation was performed with bootstrap resampling.We assessed the discrimination,calibration and accuracy of the model,and performed patient risk stratification.RESULTS Six predictors,including albumin and aspartate aminotransferase concentrations,white blood cell count,and the presence of ascites,portal vein thrombosis,and bleeding signs,were selected for the rebleeding event prediction following endoscopic treatment(REPET)model.In predicting rebleeding within 1 year,the REPET model ex-hibited a concordance index of 0.775 and a Brier score of 0.143 in the derivation cohort,alongside 0.862 and 0.127 in the validation cohort.Furthermore,the REPET model revealed a significant difference in rebleeding rates(P<0.01)between low-risk patients and intermediate-to high-risk patients in both cohorts.CONCLUSION We constructed and validated a new prognostic model for variceal rebleeding with excellent predictive per-formance,which will improve the clinical management of rebleeding in EGVB patients.
文摘A recent study by Peng et al developed a predictive model for first-instance secondary esophageal variceal bleeding in cirrhotic patients by integrating clinical and multi-organ radiomic features.The combined radiomic-clinical model demonstrated strong predictive capabilities,achieving an area under the curve of 0.951 in the training cohort and 0.930 in the validation cohort.The results highlight the potential of noninvasive prediction models in assessing esophageal variceal bleeding risk,aiding in timely clinical decision-making.Additionally,manual delineation of regions of interest raises the risk of observer bias despite efforts to minimize it.The study adjusted for clinical covariates,while some potential confounders,such as socioeconomic status,alcohol use,and liver function scores,were not included.Additionally,an imbalance in cohort sizes between the training and validation groups may reduce the statistical power of validation.Expanding the validation cohort and incorporating multi-center external validation would improve generalizability.Future studies should focus on incorporating long-term patient outcomes,exploring additional imaging modalities,and integrating automated segmentation techniques to refine the predictive model.

文摘BACKGROUND Budd-Chiari syndrome(BCS)is caused by obstruction of the hepatic veins or suprahepatic inferior vena cava,leading to portal hypertension and the development of gastroesophageal varices(GEVs),which are associated with an increased risk of bleeding.Existing risk models for variceal bleeding in cirrhotic patients have limited applicability to BCS due to differences in pathophysiology.Radiomics,as a noninvasive technique,holds promise as a tool for more accurate prediction of bleeding risk in BCS-related GEVs.AIM To develop and validate a personalized risk model for predicting variceal bleeding in BCS patients with GEVs.METHODS We retrospectively analyzed clinical data from 444 BCS patients with GEVs in two centers.Radiomic features were extracted from portal venous phase computed tomography(CT)scans.A training cohort of 334 patients was used to develop the model,with 110 patients serving as an external validation cohort.LASSO Cox regression was used to select radiomic features for constructing a radiomics score(Radscore).Univariate and multivariate Cox regression identified independent clinical predictors.A combined radiomics+clinical(R+C)model was developed using stepwise regression.Model performance was assessed using the area under the receiver operating characteristic curve(AUC),calibration plots,and decision curve analysis(DCA),with external validation to evaluate generalizability.RESULTS The Radscore comprised four hepatic and six splenic CT features,which predicted the risk of variceal bleeding.Multivariate analysis identified invasive treatment to relieve hepatic venous outflow obstruction,anticoagulant therapy,and hemoglobin levels as independent clinical predictors.The R+C model achieved C-indices of 0.906(training)and 0.859(validation),outperforming the radiomics and clinical models alone(AUC:training 0.936 vs 0.845 vs 0.823;validation 0.876 vs 0.712 vs 0.713).DCA showed higher clinical net benefit across the thresholds.The model stratified patients into low-,medium-and high-risk groups with significant differences in bleeding rates(P<0.001).An online tool is available at https://bcsvh.shinyapps.io/BCS_Variceal_Bleeding_Risk_Tool/.CONCLUSION We developed and validated a novel radiomics-based model that noninvasively and conveniently predicted risk of variceal bleeding in BCS patients with GEVs,aiding early identification and management of high-risk patients.
文摘BACKGROUND Endoscopic variceal band ligation(EVBL)represents a pivotal treatment in the prophylaxis of esophageal varices bleeding in patients with cirrhosis,but in some cases a single session of EVBL is unable to eradicate esophageal varices completely,and a control endoscopy after 2-4 weeks is required to assess eradication and/or the need for another band ligation.Liver stiffness measurement(LSM)is being increasingly used as a screening non-invasive tool to predict varices according to Baveno VII criteria.However,to date,there are no instruments able to non-invasively predict the outcome of EVBL.AIM To identify non-invasive predictors of varices eradication(VE)after EVBL through multiparametric ultrasound(US).Secondary aim was to develop a prediction model of successful variceal eradication based on non-invasive parameters.METHODS We prospectively enrolled consecutive cirrhotic patients intolerant or with contraindications to beta-blockers undergoing EVBL for bleeding prophylaxis.Patients underwent multiparametric US with LSM,spleen stiffness measurement(SSM)and dynamic contrastenhanced US(DCE-US)on liver parenchyma and portal vein,at baseline(T0)and one month(T1)after EVBL.Each US parameter and their variations from baseline were correlated with VE evaluated by control endoscopy performed at T1.RESULTS We enrolled 41 patients(median age 64 years,75.6%males).At T128 patients(68.3%)reached VE,whereas 13(31.7%)required a second EVBL.Patients who achieved VE showed a significant decrease in SSM(P=0.018),and a significant increase in peak enhancement,area under the curve and wash-in rate of both liver parenchyma and portal vein after treatment(P<0.001).Statistically significant differences between the two groups of patients were incorporated in a multivariate analysis and used to develop three prediction models.CONCLUSION A multimodal US approach based on DCE-US parameters,LSM and SSM might become a reliable predictor of VE and a useful non-invasive alternative to endoscopy.

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 Bleeding esophageal varices(BEV)is a potentially life-threatening complication in patients with portal hypertension with mortality rates as high as 25%within six weeks of the index variceal bleed.After control of the initial bleeding episode patients should enter a long-term surveillance program with endoscopic intervention combined with non-selectiveβ-blockers to prevent further bleeding and eradicate EV.AIM To assess the efficacy of endoscopic variceal ligation(EVL)in controlling acute variceal bleeding,preventing variceal recurrence and rebleeding and achieving complete eradication of esophageal varices(EV)in patients who present with BEV.METHODS A prospectively documented single-center database was used to retrospectively identify all patients with BEV who were treated with EVL between 2000 and 2018.Control of acute bleeding,variceal recurrence,rebleeding,eradication and survival were analyzed using Baveno assessment criteria.RESULTS One hundred and forty patients(100 men,40 women;mean age 50 years;range,21-84 years;Child-Pugh grade A=32;B=48;C=60)underwent 160 emergency and 298 elective EVL interventions during a total of 928 endoscopy sessions.One hundred and fourteen(81%)of the 140 patients had variceal bleeding that was effectively controlled during the index banding procedure and never bled again from EV,while 26(19%)patients had complicated and refractory variceal bleeding.EVL controlled the acute sentinel variceal bleed during the first endoscopic intervention in 134 of 140 patients(95.7%).Six patients required balloon tamponade for control and 4 other patients rebled in hospital.Overall 5-d endoscopic failure to control variceal bleeding was 7.1%(n=10)and four patients required a salvage transjugular intrahepatic portosystemic shunt.Index admission mortality was 14.2%(n=20).EV were completely eradicated in 50 of 111 patients(45%)who survived>3 mo of whom 31 recurred and 3 rebled.Sixteen(13.3%)of 120 surviving patients subsequently had 21 EV rebleeding episodes and 10 patients bled from other sources after discharge from hospital.Overall rebleeding from all sources after 2 years was 21.7%(n=26).Sixty-nine(49.3%)of the 140 patients died,mainly due to liver failure(n=46)during follow-up.Cumulative survival for the 140 patients was 71.4%at 1 year,65%at 3 years,60%at 5 years and 52.1%at 10 years.CONCLUSION EVL was highly effective in controlling the sentinel variceal bleed with an overall 5-day failure to control bleeding of 7.1%.Although repeated EVL achieved complete variceal eradication in less than half of patients with BEV,of whom 62%recurred,there was a significant reduction in subsequent rebleeding.

文摘BACKGROUND Esophageal and gastric variceal bleeding is a catastrophic complication of portal hypertension,most commonly caused by cirrhosis of various etiologies.Although a considerable body of research has been conducted in this area,the complexity of the disease and the lack of standardized treatment strategies have led to fragmented findings,insufficient information,and a lack of systematic investigation.Bibliometric analysis can help clarify research trends,identify core topics,and reveal potential future directions.Therefore,this study aims to use bibliometric methods to conduct an in-depth exploration of research progress in this field,with the expectation of providing new insights for both clinical practice and scientific research.AIM To evaluate research trends and advancements in esophagogastric variceal bleeding(EGVB)over the past twenty years.METHODS Relevant publications on EGVB were retrieved from the Web of Science Core Collection.VOSviewer,Pajek,CiteSpace,and the bibliometrix package were then employed to perform bibliometric visualizations of publication volume,countries,institutions,journals,authors,keywords,and citation counts.RESULTS The analysis focused on original research articles and review papers.From 2004 to 2023,a total of 2097 records on EGVB were retrieved.The number of relevant publications has increased significantly over the past two decades,especially in China and the United States.The leading contributors in this field,in terms of countries,institutions,authors,and journals,were China,Assistance Publique-Hôpitaux de Paris,Bosch Jaime,and World Journal of Gastroenterology,respectively.Core keywords in this field include portal hypertension,management,liver cirrhosis,risk,prevention,and diagnosis.Future research directions may focus on optimizing diagnostic methods,personalized treatment,and multidisciplinary collaboration.CONCLUSION Using bibliometric methods,this study reveals the developmental trajectory and trends in research on EGVB,underscoring risk assessment and diagnostic optimization as the core areas of current focus.The study provides an innovative and systematic perspective for this field,indicating that future research could center on multidisciplinary collaboration,personalized treatment approaches,and the development of new diagnostic tools.Moreover,this work offers practical research directions for both the academic community and clinical practice,driving continued advancement in this domain.
文摘BACKGROUND Cirrhosis-related upper gastrointestinal bleeding(UGIB)poses a fatal risk,and endoscopic ligation as a sole intervention shows inadequate effectiveness.AIM To evaluate the therapeutic efficacy of endoscopic variceal ligation(EVL)plus pro-pranolol vs EVL monotherapy in patients with cirrhosis complicated with acute UGIB and identify predictors for clinical outcomes.METHODS This study enrolled 99 consecutive patients with cirrhosis presenting with acute UGIB between January 2024 and January 2025.Participants were allocated to either the control group(n=49)receiving EVL alone or(2)the research group(n=50)receiving EVL plus propranolol.Primary outcomes included treatment efficacy,venous blood flow[portal venous flow(PVF)/splenic venous flow(SVF)],and postoperative outcomes(hemostasis time,length of hospital stay,and rebleeding rates).Univariate and multivariate regression analyses were conducted to determine independent predictors of treatment response.RESULTS Compared with the control group,the research group demonstrated significantly better outcomes,including higher overall treatment efficacy,greater reductions in PVF and SVF,shorter hemostasis time and hospital stay,and lower rebleeding rates.Univariate analysis demonstrated significant associations between treatment efficacy and age,cirrhosis duration,Child-Pugh grade,bleeding duration,and treatment approach in patients with cirrhosis complicated with acute UGIB.Multivariate logistic regression identified three independent risk factors for poor outcomes,namely,advanced age(>55 years),prolonged cirrhosis duration(≥4 years),and delayed bleeding intervention(>24 hours).CONCLUSION The EVL plus propranolol regimen demonstrates significant efficacy in treating UGIB in cirrhosis,outperforming EVL alone in improving hemodynamics(PVF/SVF),shortening hemostasis and hospitalization duration,and reducing rebleeding rates.Moreover,advanced age,prolonged disease duration,and longer bleeding times are independent risk factors for poor therapeutic outcomes.
文摘Gastric variceal(GV)bleeding remains a life-threatening complication of portal hypertension,with ongoing debate regarding the optimal endoscopic therapy.Conventional endoscopic cyanoacrylate injection(ECI)is effective but limited by the risk of ectopic embolism,particularly in the presence of gastrorenal shunts.Clip-assisted ECI(clip-ECI)has emerged as a novel modification designed to reduce embolic risk while maintaining hemostatic efficacy.We appraised the recent study by Xiong et al,which compared clip-ECI with endoscopic ultrasoundguided coil and cyanoacrylate injection in 108 propensity-matched patients with cardiofundal varices and shunts.Both techniques demonstrated comparable efficacy,with obliteration rates exceeding 90%and similar one-year rebleeding rates.Importantly,no embolic events were reported.These findings are consistent with prior studies,including multicenter cohorts and a recent randomized controlled trial,which highlight clip-ECI as a safe,effective,and efficient technique,with advantages of shorter procedure times,fewer sessions,and lower costs.While endoscopic ultrasound(EUS)-guided therapy offers precision in expert hands,clip-ECI provides a practical,accessible alternative,particularly in resource-limited settings.Larger prospective studies with standardized definitions and cost-effectiveness analyses are needed to refine treatment algorithms.Clip-ECI represents a promising“flow-control assisted”strategy and a real-world alternative to EUS-based therapies for GV.

文摘BACKGROUND The high rebleeding rate and severe adverse events have raised concerns regarding the safety of endoscopic cyanoacrylate as a conventional treatment for gastric variceal hemorrhage.Clip-assisted endoscopic cyanoacrylate injection(Clip-CYA)and endoscopic ultrasound-guided coil and cyanoacrylate injection(EUS-CG)are two currently used modalities.There are limited data comparing the two techniques.AIM To compare the efficacy,safety,and procedural characteristics of Clip-CYA vs EUS-CG for treatment of gastric varices(GVs)with spontaneous portosystemic shunts.METHODS Between April 2019 and August 2023,162 patients with GVs and concomitant gastrorenal or splenorenal shunts who underwent either Clip-CYA or EUS-CG at our center were included.After 1:2 propensity score matching,108 patients were included in the final analysis.The evaluated outcomes included the amount of cyanoacrylate,eradication of GVs,cyanoacrylate embolization,all-cause rebleeding,operating time and endoscopic therapy costs.RESULTS Of the 108 patients,72(male,83.3%;mean age,56.2±10.8 years)received Clip-CYA,and 36(male,72.2%;mean age,59.1±10.7 years)received EUS-CG.The amount of cyanoacrylate used,rates of obliteration of GVs and all-cause rebleeding were similar between the two groups(2.0±1.1 mL vs 2.0±0.6 mL,P=0.913;91.7%vs 94.4%,P=0.603;and 23.6%vs 19.4%,P=0.623,respectively).No cyanoacrylate embolization occurred in either group.Compared with EUS-CG,Clip-CYA was associated with significantly shorter operating times(24.0±9.9 minutes vs 47.1±21.0 minutes,P<0.001)and lower endoscopic therapy costs(7523.4±5719.4 Chinese yuan vs 11153.7±7679.1 Chinese yuan,P=0.007).These advantages persisted in the subgroup analysis of patients whose GVs had a maximum diameter>3 cm or>4 cm.CONCLUSION Compared with EUS-CG,Clip-CYA of GVs appears to be a safe procedure with shorter operating times and lower endoscopic therapy costs.
文摘BACKGROUND Hepatitis C virus(HCV)infection remains a major public health issue in Egypt,with a high prevalence of genotype 4.Direct-acting antivirals(DAAs)achieve>95%sustained virologic response(SVR),but their impact on variceal rebleeding in genotype 4 cirrhotic patients is underexplored.This study evaluated the association between DAA therapy and variceal rebleeding in Egyptian patients with HCV-related cirrhosis.AIM To evaluate the association between DAA therapy and variceal rebleeding in Egyptian patients with HCV-related cirrhosis.METHODS A multicenter retrospective cohort study included HCV genotype 4 cirrhotic patients from five Egyptian centers with a first variceal bleeding episode.Patients were divided into DAA-treated(Group A)and non-treated(Group B)groups and followed for 5 years.Propensity score matching(PSM),Cox regression,and competing risk analysis were adjusted for confounders.RESULTS DAA treatment significantly reduced variceal rebleeding(HR 2.57;95%CI:1.39-4.72;P=0.002),ascites development over 5 years(6.8%vs 27.1%,P=0.006),and hepatic dysfunction progression.During treatment,it improved liver function[lower model for end-stage liver disease(MELD),stable Child-Pugh class]and reduced complications.All Group A patients achieved SVR by PCR,while Group B remained HCV-positive,likely contributing to the observed reductions in rebleeding and hepatic decompensation.These benefits persisted over 5 years,with longer survival without rebleeding(4.5 years vs 3.2 years),lower MELD(7 vs 12,P<0.001),and reduced hepatic decompensation(Child-Pugh progression:5.1%vs 35.6%,P<0.001).At 5 years,the DAA group had better liver function(higher albumin,lower international normalized ratio,improved platelets),while the non-DAA group worsened.PSM confirmed these findings(HR:0.45,95%CI:0.27-0.75,P=0.002),and competing risk analysis showed sustained protection(sub-distribution HR:0.44,95%CI:0.26-0.74,P=0.002).Endoscopy revealed variceal regression with DAA but progression in the non-DAA group.DAA therapy significantly reduced variceal rebleeding,hepatic decompensation,and mortality(8.5%vs 20.3%,P=0.045),with survival benefits linked to SVR.Additionally,it was associated with improved survival,with a lower 5-year mortality rate in the DAA group(8.5%vs 20.3%,P=0.045).The protective effect of DAA therapy remained consistent across multivariable Cox regression,time-dependent modeling,and competing risk analyses.CONCLUSION DAA treatment in HCV-related cirrhosis significantly reduces variceal rebleeding,ascites development,and hepatic dysfunction progression.The 5-year follow-up data demonstrate sustained improvements in liver function and hematologic parameters,underscoring the long-term benefits of DAA therapy.

文摘BACKGROUND Severe esophagogastric varices(EGVs)significantly affect prognosis of patients with hepatitis B because of the risk of life-threatening hemorrhage.Endoscopy is the gold standard for EGV detection but it is invasive,costly and carries risks.Noninvasive predictive models using ultrasound and serological markers are essential for identifying high-risk patients and optimizing endoscopy utilization.Machine learning(ML)offers a powerful approach to analyze complex clinical data and improve predictive accuracy.This study hypothesized that ML models,utilizing noninvasive ultrasound and serological markers,can accurately predict the risk of EGVs in hepatitis B patients,thereby improving clinical decisionmaking.AIM To construct and validate a noninvasive predictive model using ML for EGVs in hepatitis B patients.METHODS We retrospectively collected ultrasound and serological data from 310 eligible cases,randomly dividing them into training(80%)and validation(20%)groups.Eleven ML algorithms were used to build predictive models.The performance of the models was evaluated using the area under the curve and decision curve analysis.The best-performing model was further analyzed using SHapley Additive exPlanation to interpret feature importance.RESULTS Among the 310 patients,124 were identified as high-risk for EGVs.The extreme gradient boosting model demonstrated the best performance,achieving an area under the curve of 0.96 in the validation set.The model also exhibited high sensitivity(78%),specificity(94%),positive predictive value(84%),negative predictive value(88%),F1 score(83%),and overall accuracy(86%).The top four predictive variables were albumin,prothrombin time,portal vein flow velocity and spleen stiffness.A web-based version of the model was developed for clinical use,providing real-time predictions for high-risk patients.CONCLUSION We identified an efficient noninvasive predictive model using extreme gradient boosting for EGVs among hepatitis B patients.The model,presented as a web application,has potential for screening high-risk EGV patients and can aid clinicians in optimizing the use of endoscopy.
文摘Endoscopic ultrasound(EUS)guided vascular interventions have expanded the reach of therapeutic endoscopy to include vascular pathology previously inaccessible by endoscopists.Gastric variceal bleeding comprises 20%of all variceal bleeding and is associated with high morbidity and mortality.Historically,endoscopic injection of thrombosis-inducing agents such as glue has been used.However,glue injection carries potential risks including systemic embolization,damage to the endoscope,and recurrent bleeding.The introduction of hemostatic coils has revolutionized the endoscopic approach,with EUS-guided coil embolization emerging as an effective and safe modality for the management of gastric varices(GVs).When compared with conventional glue injection,EUSguided embolization is associated with improved visualization,higher efficacy,and better safety profile.Despite its expanding adoption,the standardization of EUS guided embolization remains a challenge.High-quality studies are needed to standardize this promising technique and define its role in clinical practice.In this review,we will discuss the indications,efficacy,techniques,and various approaches for EUS-guided embolization of GVs.
文摘A multicenter study recently published introduced a novel prognostic model for predicting esophagogastric variceal rebleeding after endoscopic treatment in patients with cirrhosis.The model incorporated six readily available clinical variables—albumin level,aspartate aminotransferase level,white blood cell count,ascites,portal vein thrombosis,and bleeding signs—and demonstrated promising predictive performance.However,limitations,including the retrospective design and exclusion of patients with hepatocellular carcinoma,may affect the generaliz-ability of the model.Additionally,further improvement is needed in the model’s discrimination between intermediate-and high-risk groups in external.Prospec-tive validation and inclusion of additional variables are recommended to enhan-ce predictive accuracy across diverse clinical scenarios.
文摘BACKGROUND Globally,Liver cirrhosis is the 14th leading cause of death and poses a significant threat to human health.AIM To investigate the effects of a multidisciplinary collaboration model on postoperative recovery and psychological stress in patients with liver cirrhosis undergoing esophageal variceal bleeding(EVB)surgery within an integrated healthcare system.METHODS Between January 2022 and March 2024,a total of 180 patients with cirrhosis and EVB were admitted and randomly assigned to either a control group(standard care)or an observation group(standard care plus the multidisciplinary collaboration model),with 90 patients in each group.Postoperative recovery indicators(time to symptom improvement,time to start eating,time to bowel sound recovery,time to first flatus,and hospital stay),psychological stress responses[selfrating anxiety scale(SAS);self-rating depression scale(SDS)],subjective wellbeing,and incidence of complications were compared between the two groups.RESULTS Compared to the control group,the observation group showed earlier symptom improvement,earlier return to eating,bowel sound recovery,first flatus,and a shorter hospital stay.Pre-intervention SAS and SDS scores were not significantly different between the groups,but post-intervention scores were significantly lower in the observation group.Similarly,there was no significant difference in the subjective well-being scores before the intervention between the two groups.After the intervention,both groups showed improved scores,with the observation group scoring significantly higher than the control group.CONCLUSION The observation group also had a lower incidence of complications.Therefore,for patients with liver cirrhosis undergoing EVB surgery,a multidisciplinary collaboration model within an integrated healthcare system can promote early postoperative recovery,reduces psychological stress,improves subjective well-being,and reduces complications and rebleeding.

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)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.
