Cheng’s Classification of PVTT, total bilirubin and Child-Pugh class wereindependently negative associated with OS (all P < 0.05). The main causes of death were liver failure or hepaticencephalopathy (75.9%) in the TIPS group and rebleeding (68.8%) in the standard treatment.CONCLUSIONTIPS could reduce the risk of early death due to rebleeding and prolong short-term survival in HCC patients withPVTT and acute EGVB, which deserves further investigation.展开更多

METHODS: Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected. Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB. RESULTS: Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding. Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding; previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P 〈 0.001), red vomitus (OR 4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011). The UGIB Etiology Score was calculated from (3.1× previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5× red vomitus) + (1.2× red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%, 82%, 50%, and 96%, respectively. The score was prospectively validated in cases (46 variceal and 149 another set of 195 UGIB non-variceal bleeding). The PPV and NPV of a score ≥ 3.1 for variceal bleeding were 79% and 97%, respectively. CONCLUSION: The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.展开更多

METHODSOne hundred thirty-nine newly diagnosed cirrhotic patients without variceal bleeding were included in this analysis. Model for end-stage liver disease (MELD), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT), AST to platelet ratio index (APRI), platelet count to spleen diameter (PC/SD), fibrosis-4-index (FIB-4), fibrosis index (FI) and King’s Score were measured for all participants. All patients underwent endoscopic assessment within two days of hospitalization. The major end point was the first esophageal variceal bleeding (EVB) event. The diagnostic performance of “predictors” for the presence of EV and EVB were assessed by sensitivity and specificity values obtained from the receiver operating characteristics procedure. RESULTSFIB-4 was the only strong and significant “predictor” of esophageal varices (multivariable-adjusted OR = 1.57 for one unit increment; 95%CI: 1.15-2.14). Furthermore, a cut-off value of 3.23 for FIB-4 was a significant predictor of esophageal varices, with a sensitivity of 72%, a specificity of 58% and a proportion of area under the curve (AUC) of 66% (P = 0.01). During the follow-up (median: 31.5 mo; interquartile range: 11-59 mo), 34 patients (24%) experienced a first EVB. FIB-4 was a poor predictor of EVB (the AUC was only 51%) for a cut-off value of 5.02. Furthermore, the AUC of AST/ALT, APRI, PC/SD, FI, MELD and King’s Score ranged from 45% to 55%. None of the non-invasive markers turned out to be a useful predictor of EVB. CONCLUSIONDespite the low diagnostic accuracy, FIB-4 appears the most efficient non-invasive liver fibrosis marker which can be used as an initial screening tool for cirrhotic patients.展开更多

This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB.METHODS: The data were retrospectively retrieved from 479 cirrhotic patients(Child-Pugh A or B class) with PHRVB, who had undergone TIPS(TIPS group) or OSED(OSED group) between January 1, 2010 and October 31, 2014.RESULTS: A total of 196 patients received TIPS, whereas 283 underwent OSED. Within one month after TIPS and OSED, the rebleeding rates were 6.1% and 3.2%, respectively(P=0.122). Significantly lower incidence of pleural effusion,splenic vein thrombosis, and pulmonary infection, as well as higher hepatic encephalopathy rate, shorter postoperative length of hospital stay, and higher hospital costs were observed in the TIPS group than those in the OSED group. During the follow-up periods(29 months), significantly higher incidences of rebleeding(15.3% vs 4.6%, P=0.001) and hepatic encephalopathy(17.3% vs 3.9%, P=0.001) were observed in the TIPS group than in the OSED group. The incidence of instent stenosis was 18.9%. The survival rates were 91.3% in the TIPS group and 95.1% in the OSED group. The long-term liver function did not worsen after either TIPS or OSED.CONCLUSION: For the patients with liver function in the Child-Pugh A or B class, TIPS is not superior over OSED in terms of PHRVB treatment and rebleeding prevention.展开更多

文摘BACKGROUND Esophageal-gastric variceal bleeding(EGVB)represents a severe complication among patients with cirrhosis and often culminates in fatal outcomes.Interven-tional therapy,a rapidly developing treatment modality over the past few years,has found widespread application in clinical practice due to its minimally inva-sive characteristics.However,whether transjugular intrahepatic portosystemic shunt(TIPS)treatment has an impact on patient prognosis remains controversial.METHODS A retrospective study was conducted on ninety-two patients presenting with cirrhotic EGVB who were admitted to our hospital between September 2020 and September 2022.Based on the different modes of treatment,the patients were assigned to the study group(TIPS received,n=50)or the control group(per-cutaneous transhepatic varices embolization received,n=42).Comparative ana-lyses were performed between the two groups preoperatively and one month postoperatively for the following parameters:Varicosity status;hemodynamic parameters[portal vein flow velocity(PVV)and portal vein diameter(PVD);platelet count(PLT);red blood cell count;white blood cell count(WBC);and hepatic function[albumin(ALB),total bilirubin(TBIL),and aspartate transaminase(AST)].The Generic Quality of Life Inventory-74 was utilized to assess quality of life in the two groups,and the 1-year postoperative rebleeding and survival rates were compared.RESULTS Following surgical intervention,there was an improvement in the incidence of varicosity compared to the preoperative status in both cohorts.Notably,the study group exhibited more pronounced enhancements than did the control group(P<0.05).PVV increased,and PVD decreased compared to the preoperative values,with the study cohort achieving better outcomes(P<0.05).PLT and WBC counts were elevated postoperatively in the two groups,with the study cohort displaying higher PLT and WBC counts(P<0.05).No differences were detected between the two groups in terms of serum ALB,TBIL,or AST levels either preoperatively or postoperatively(P<0.05).Postoperative scores across all dimensions of life quality surpassed preoperative scores,with the study cohort achieving higher scores(P<0.05).At 22.00%,the one-year postoperative rebleeding rate in the study cohort was significantly lower than that in the control group(42.86%;P<0.05);conversely,no marked difference was obser-ved in the 1-year postoperative survival rate between the two cohorts(P>0.05).CONCLUSION TIPS,which has demonstrated robust efficacy in managing cirrhotic EGVB,remarkably alleviates varicosity and improves hemodynamics in patients.This intervention not only results in a safer profile but also contributes significantly to a more favorable prognosis.
文摘Jejunal variceal bleeding at the site of hepaticojejunostomy after pancre-aticoduodenectomy due to portal hypertension caused by extrahepatic portal vein obstruction is a life-threatening complication and is very difficult to treat.Pharma-cotherapy,endoscopic methods,transcatheter embolization of veins supplying the jejunal afferent loop,portal venous stenting,and surgical procedures can be used for the treatment of jejunal variceal bleeding.Nevertheless,the optimal mana-gement strategy has not yet been established,which is due to the lack of ran-domized controlled trials involving a large cohort of patients necessary for their development.
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BACKGROUND Radiomics has been used in the diagnosis of cirrhosis and prediction of its associated complications.However,most current studies predict the risk of esophageal variceal bleeding(EVB)based on image features at a single level,which results in incomplete data.Few studies have explored the use of global multi-organ radiomics for non-invasive prediction of EVB secondary to cirrhosis.AIM To develop a model based on clinical and multi-organ radiomic features to predict the risk of first-instance secondary EVB in patients with cirrhosis.METHODS In this study,208 patients with cirrhosis were retrospectively evaluated and randomly split into training(n=145)and validation(n=63)cohorts.Three areas were chosen as regions of interest for extraction of multi-organ radiomic features:The whole liver,whole spleen,and lower esophagus–gastric fundus region.In the training cohort,radiomic score(Rad-score)was created by screening radiomic features using the inter-observer and intra-observer correlation coefficients and the least absolute shrinkage and selection operator method.Independent clinical risk factors were selected using multivariate logistic regression analyses.The radiomic features and clinical risk variables were combined to create a new radiomics-clinical model(RC model).The established models were validated using the validation cohort.BACKGROUND Radiomics has been used in the diagnosis of cirrhosis and prediction of its associated complications.However,most current studies predict the risk of esophageal variceal bleeding(EVB)based on image features at a single level,which results in incomplete data.Few studies have explored the use of global multi-organ radiomics for non-invasive prediction of EVB secondary to cirrhosis.AIM To develop a model based on clinical and multi-organ radiomic features to predict the risk of first-instance secondary EVB in patients with cirrhosis.METHODS In this study,208 patients with cirrhosis were retrospectively evaluated and randomly split into training(n=145)and validation(n=63)cohorts.Three areas were chosen as regions of interest for extraction of multi-organ radiomic features:The whole liver,whole spleen,and lower esophagus–gastric fundus region.In the training cohort,radiomic score(Rad-score)was created by screening radiomic features using the inter-observer and intra-observer correlation coefficients and the least absolute shrinkage and selection operator method.Independent clinical risk factors were selected using multivariate logistic regression analyses.The radiomic features and clinical risk variables were combined to create a new radiomics-clinical model(RC model).The established models were validated using the validation cohort.RESULTS The RC model yielded the best predictive performance and accurately predicted the EVB risk of patients with cirrhosis.Ascites,portal vein thrombosis,and plasma prothrombin time were identified as independent clinical risk factors.The area under the receiver operating characteristic curve(AUC)values for the RC model,Rad-score(liver+spleen+esophagus),Rad-score(liver),Rad-score(spleen),Rad-score(esophagus),and clinical model in the training cohort were 0.951,0.930,0.801,0.831,0.864,and 0.727,respectively.The corresponding AUC values in the validation cohort were 0.930,0.886,0.763,0.792,0.857,and 0.692.CONCLUSION In patients with cirrhosis,combined multi-organ radiomics and clinical model can be used to non-invasively predict the probability of the first secondary EVB.
文摘This editorial describes the contemporary concepts of prevention and management of gastroesophageal variceal bleeding in liver cirrhosis(LC)patients according to the current guidelines.Gastroesophageal variceal bleeding is the most dangerous complication of portal hypertension in LC patients.Risk stratification and determination of an individual approach to the choice of therapeutic measures aimed at their prevention and management has emerged as one of the top concerns in modern hepatology.According to the current guidelines,in the absence of clinically significant portal hypertension,etiological and nonetiological therapies of LC is advisable for the primary preventing gastroesophageal variceal bleeding,whereas its presence serves as an indication for the administration of non-selectiveβ-blockers,among which carvedilol is the drug of choice.Non-selectiveβ-blockers,as well as endoscopic variceal ligation and transjugular intrahepatic portosystemic shunt can be used to prevent recurrence of gastroesophageal variceal bleeding.Pharmacotherapy with vasoactive drugs(terlipressin,somatostatin,octreotide),endoscopic variceal ligation,endovascular techniques and transjugular intrahepatic portosystemic shunt are recommended for the treatment of acute gastroesophageal variceal bleeding.Objective and accurate risk stratification of gastroesophageal variceal bleeding will allow developing individual strategies for their prevention and management,avoiding the first and further decompensation in LC,which will improve the prognosis and survival of patients suffering from it.
文摘BACKGROUND Whether hepatocellular carcinoma(HCC)with portal vein tumor thrombus(PVTT)and acute esophagogastric variceal bleeding(EGVB)can improve the success rate of endoscopic hemostasis and overall survival(OS)from transjugular intrahepatic portosystemic shunt(TIPS)remains controversial.AIM To compare the clinical outcomes between TIPS and standard treatment for such HCC patients.METHODS This monocenter,retrospective cohort study included patients diagnosed as HCC with PVTT and upper gastrointestinal bleeding.Patients were grouped by the treatment(TIPS or standard conservative treatment).The success rate of en-doscopic hemostasis,OS,rebleeding rates,and main causes of death were ana-lyzed.RESULTS Between July 2015 and September 2021,a total of 77 patients(29 with TIPS and 48 with standard treatment)were included.The success rate of endoscopic hemostasis was 96.6%in the TIPS group and 95.8%in the standard treatment group.All the 29 patients in TIPS group successful underwent TIPS procedure and had a better OS compared with standard treatment within the first 160 days after treatment(68 days vs 43 days,P=0.022),but shorter OS after 160 days(298 days vs 472 days, P = 0.022). Cheng’s Classification of PVTT, total bilirubin and Child-Pugh class wereindependently negative associated with OS (all P < 0.05). The main causes of death were liver failure or hepaticencephalopathy (75.9%) in the TIPS group and rebleeding (68.8%) in the standard treatment.CONCLUSIONTIPS could reduce the risk of early death due to rebleeding and prolong short-term survival in HCC patients withPVTT and acute EGVB, which deserves further investigation.
文摘In this editorial,we comment on the minireview by Martino A,published in the recent issue of World Journal of Gastrointestinal Endoscopy 2023;15(12):681-689.We focused mainly on the possibility of replacing the hepatic venous pressure gradient(HVPG)and endoscopy with noninvasive methods for predicting esophageal variceal bleeding.The risk factors for bleeding were the size of the varices,the red sign and the Child-Pugh score.The intrinsic core factor that drove these changes was the HVPG.Therefore,the present studies investigating noninvasive methods,including computed tomography,magnetic resonance imaging,elastography,and laboratory tests,are working on correlating imaging or serum marker data with intravenous pressure and clinical outcomes,such as bleeding.A single parameter is usually not enough to construct an efficient model.Therefore,multiple factors were used in most of the studies to construct predictive models.Encouraging results have been obtained,in which bleeding prediction was partly reached.However,these methods are not satisfactory enough to replace invasive methods,due to the many drawbacks of different studies.There is still plenty of room for future improvement.Prediction of the precise timing of bleeding using various models,and extracting the texture of variceal walls using high-definition imaging modalities to predict the red sign are interesting directions to lay investment on.
文摘This letter to the editor relates to the study entitled“The role of computed tomography for the prediction of esophageal variceal bleeding:Current status and future perspectives”.Esophageal variceal bleeding(EVB)is one of the most common and severe complications related to portal hypertension(PH).Despite marked advances in its management during the last three decades,EVB is still associated with significant morbidity and mortality.The risk of first EVB is related to the severity of both PH and liver disease,and to the size and endoscopic appearance of esophageal varices.Indeed,hepatic venous pressure gradient(HVPG)and esophagogastroduodenoscopy(EGD)are currently recognized as the“gold standard”and the diagnostic reference standard for the prediction of EVB,respectively.However,HVPG is an invasive,expensive,and technically complex procedure,not widely available in clinical practice,whereas EGD is mainly limited by its invasive nature.In this scenario,computed tomography(CT)has been recently proposed as a promising modality for the non-invasive prediction of EVB.While CT serves solely as a diagnostic tool and cannot replace EGD or HVPG for delivering therapeutic and physiological information,it has the potential to enhance the prediction of EVB more effectively when combined with liver disease scores,HVPG,and EGD.However,to date,evidence concerning the role of CT in this setting is still lacking,therefore we aim to summarize and discuss the current evidence concerning the role of CT in predicting the risk of EVB.

文摘BACKGROUND Esophagogastric variceal bleeding(EGVB)is a serious complication of patients with decompensated cirrhosis and is associated with high mortality and morbidity.Early diagnosis and screening of cirrhotic patients at risk for EGVB is crucial.Currently,there is a lack of noninvasive predictive models widely available in clinical practice.AIM To develop a nomogram based on clinical variables and radiomics to facilitate the noninvasive prediction of EGVB in cirrhotic patients.METHODS A total of 211 cirrhotic patients hospitalized between September 2017 and December 2021 were included in this retrospective study.Patients were divided into training(n=149)and validation(n=62)groups at a 7:3 ratio.Participants underwent three-phase computed tomography(CT)scans before endoscopy,and radiomic features were extracted from portal venous phase CT images.The independent sample t-test and least absolute shrinkage and selection operator logistic regression were used to screen out the best features and establish a radiomics signature(RadScore).Univariate and multivariate analyses were performed to determine the independent predictors of EGVB in clinical settings.A noninvasive predictive nomogram for the risk of EGVB was built using independent clinical predictors and RadScore.Receiver operating characteristic,calibration,clinical decision,and clinical impact curves were applied to evaluate the model’s performance.RESULTS Albumin(P=0.001),fibrinogen(P=0.001),portal vein thrombosis(P=0.002),aspartate aminotransferase(P=0.001),and spleen thickness(P=0.025)were selected as independent clinical predictors of EGVB.RadScore,constructed with five CT features of the liver region and three of the spleen regions,performed well in training(area under the receiver operating characteristic curve(AUC)=0.817)as well as in validation(AUC=0.741)cohorts.There was excellent predictive performance in both the training and validation cohorts for the clinical-radiomics model(AUC=0.925 and 0.912,respectively).Compared with the existing noninvasive models such as ratio of aspartate aminotransferase to platelets and Fibrosis-4 scores,our combined model had better predictive accuracy with the Delong's test less than 0.05.The Nomogram had a good fit in the calibration curve(P>0.05),and the clinical decision curve further supported its clinical utility.CONCLUSION We designed and validated a clinical-radiomics nomogram able to noninvasively predict whether cirrhotic patients will develop EGVB,thus facilitating early diagnosis and treatment.

文摘BACKGROUND Portal hypertension combined with esophagogastric variceal bleeding(EGVB)is a serious complication in patients with hepatitis B virus(HBV)-related cirrhosis in China.Splenectomy plus pericardial devascularization(SPD)and transjugular intrahepatic portosystemic shunt(TIPS)are effective treatments for EGVB.However,a comparison of the effectiveness and safety of those methods is lacking.AIM To compare the prognosis after SPD vs TIPS for acute EGVB after failure of endoscopic therapy or secondary prophylaxis of variceal rebleeding(VRB)in patients with HBV-related cirrhosis combined with portal hypertension.METHODS This retrospective cohort study included 318 patients with HBV-related cirrhosis and EGVB who underwent SPD or TIPS at West China Hospital of Sichuan University during 2009-2013.Propensity score-matched analysis(PSM),the Kaplan-Meier method,and multivariate Cox regression analysis were used to compare overall survival,VRB rate,liver function abnormality rate,and hepatocellular carcinoma(HCC)incidence between the two patient groups.RESULTS The median age was 45.0 years(n=318;226(71.1%)males).During a median follow-up duration of 43.0 mo,18(11.1%)and 33(21.2%)patients died in the SPD and TIPS groups,respectively.After PSM,SPD was significantly associated with better overall survival(OS)(P=0.01),lower rates of abnormal liver function(P<0.001),and a lower incidence of HCC(P=0.02)than TIPS.The VRB rate did not differ significantly between the two groups(P=0.09).CONCLUSION Compared with TIPS,SPD is associated with higher postoperative OS rates,lower rates of abnormal liver function and HCC,and better quality of survival as acute EGVB treatment after failed endoscopic therapy or as secondary prophylaxis of VRB in patients with HBV-related cirrhosis combined with portal hypertension.There is no significant between-group difference in VRB rates.

文摘BACKGROUND Esophageal-gastro varices bleeding(EGVB)is the most widely known cause of mortality in individuals with cirrhosis,with an occurrence rate of 5%to 15%.Among them,gastric varices bleeding(GVB)is less frequent than esophageal varices bleeding(EVB),but the former is a more critical illness and has a higher mortality rate.At present,endoscopic variceal histoacryl injection therapy(EVHT)is safe and effective,and it has been recommended by relevant guidelines as the primary method for the treatment of GVB.However,gastric varices after endoscopic treatment still have a high rate of early rebleeding,which is mainly related to complications of its treatment,such as bleeding from drained ulcers,rebleeding of varices etc.Therefore,preventing early postoperative rebleeding is very important to improve the quality of patient survival and outcomes.AIM To assess the efficacy of aluminium phosphate gel(APG)combined with proton pump inhibitor(PPI)in preventing early rebleeding after EVHT in individuals with GVB.METHODS Medical history of 196 individuals with GVB was obtained who were diagnosed using endoscopy and treated with EVHT in Shenzhen People's Hospital from January 2016 to December 2021.Based on the selection criteria,101 patients were sorted into the PPI alone treatment group,and 95 patients were sorted into the PPI combined with the APG treatment group.The incidences of early rebleeding and corresponding complications within 6 wk after treatment were compared between both groups.Statistical methods were performed by two-sample t-test,Wilcoxon rank sum test andχ2 test.RESULTS No major variations were noted between the individuals of the two groups in terms of age,gender,Model for End-Stage Liver Disease score,coagulation function,serum albumin,hemoglobin,type of gastric varices,the dose of tissue glue injection and EV that needed to be treated simultaneously.The early rebleeding rate in PPI+APG group was 3.16%(3/95),which was much lower than that in the PPI group(12.87%,13/101)(P=0.013).Causes of early rebleeding:the incidence of gastric ulcer bleeding in the PPI+APG group was 2.11%(2/95),which was reduced in comparison to that in the PPI group(11.88%,12/101)(P=0.008);the incidence of venous bleeding in PPI+APG group and PPI group was 1.05%(1/95)and 0.99%(1/101),respectively,and there was no significant difference between them(0.999).The early mortality rate was 0 in both groups within 6 wk after the operation,and the low mortality rate was related to the timely hospitalization and active treatment of all patients with rebleeding.The overall incidence of complications in the PPI+APG group was 12.63%(12/95),which was not significantly different from 13.86%(14/101)in the PPI group(P=0.800).of abdominal pain in the PPI+APG group was 3.16%(3/95),which was lower than that in the PPI group(11.88%,12/101)(P=0.022).However,due to aluminum phosphate gel usage,the incidence of constipation in the PPI+APG group was 9.47%(9/95),which was higher than that in the PPI group(1.98%,2/101)(P=0.023),but the health of the patients could be improved by increasing drinking water or oral lactulose.No patients in either group developed spontaneous peritonitis after taking PPI,and none developed hepatic encephalopathy and ectopic embolism within 6 wk of EVHT treatment.CONCLUSION PPI combined with APG can significantly reduce the incidence of early rebleeding and postoperative abdominal pain in cirrhotic patients with GVB after taking EVHT.
文摘AIM: To identify clinical parameters, and develop an Upper Gastrointesinal Bleeding (UGIB) Etiology Score for predicting the types of UGIB and validate the score. METHODS: Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected. Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB. RESULTS: Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding. Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding; previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P 〈 0.001), red vomitus (OR 4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011). The UGIB Etiology Score was calculated from (3.1× previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5× red vomitus) + (1.2× red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%, 82%, 50%, and 96%, respectively. The score was prospectively validated in cases (46 variceal and 149 another set of 195 UGIB non-variceal bleeding). The PPV and NPV of a score ≥ 3.1 for variceal bleeding were 79% and 97%, respectively. CONCLUSION: The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.
文摘To assess “predictors” of esophageal varices (EV) and variceal bleeding using non-invasive markers in Albanian patients diagnosed with liver cirrhosis. METHODSOne hundred thirty-nine newly diagnosed cirrhotic patients without variceal bleeding were included in this analysis. Model for end-stage liver disease (MELD), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT), AST to platelet ratio index (APRI), platelet count to spleen diameter (PC/SD), fibrosis-4-index (FIB-4), fibrosis index (FI) and King’s Score were measured for all participants. All patients underwent endoscopic assessment within two days of hospitalization. The major end point was the first esophageal variceal bleeding (EVB) event. The diagnostic performance of “predictors” for the presence of EV and EVB were assessed by sensitivity and specificity values obtained from the receiver operating characteristics procedure. RESULTSFIB-4 was the only strong and significant “predictor” of esophageal varices (multivariable-adjusted OR = 1.57 for one unit increment; 95%CI: 1.15-2.14). Furthermore, a cut-off value of 3.23 for FIB-4 was a significant predictor of esophageal varices, with a sensitivity of 72%, a specificity of 58% and a proportion of area under the curve (AUC) of 66% (P = 0.01). During the follow-up (median: 31.5 mo; interquartile range: 11-59 mo), 34 patients (24%) experienced a first EVB. FIB-4 was a poor predictor of EVB (the AUC was only 51%) for a cut-off value of 5.02. Furthermore, the AUC of AST/ALT, APRI, PC/SD, FI, MELD and King’s Score ranged from 45% to 55%. None of the non-invasive markers turned out to be a useful predictor of EVB. CONCLUSIONDespite the low diagnostic accuracy, FIB-4 appears the most efficient non-invasive liver fibrosis marker which can be used as an initial screening tool for cirrhotic patients.
文摘Bacterial infections are common in cirrhotic patients with acute variceal bleeding,occurring in 20%within48 h.Outcomes including early rebleeding and failure to control bleeding are strongly associated with bacterial infection.However,mortality from variceal bleeding is largely determined by the severity of liver disease.Besides a higher Child-Pugh score,patients with hepatocellular carcinoma are particularly susceptible to infections.Despite several hypotheses that include increased use of instruments,greater risk of aspiration pneumonia and higher bacterial translocation,it remains debatable whether variceal bleeding results in infection or vice versa but studies suggest that antibiotic prophylaxis prior to endoscopy and up to 8 h is useful in reducing bacteremia and spontaneous bacterial peritonitis.Aerobic gram negative bacilli of enteric origin are most commonly isolated from cultures,but more recently,gram positives and quinolone-resistant organisms are increasingly seen,even though their clinical significance is unclear.Fluoroquinolones(including ciprofloxacin and norfloxacin)used for short term(7 d)have the most robust evidence and are recommended in most expert guidelines.Short term intravenous cephalosporin(especially ceftriaxone),given in a hospital setting with prevalent quinolone-resistant organisms,has been shown in studies to be beneficial,particularly in high risk patients with advanced cirrhosis.
文摘BACKGROUND: Transjugular intrahepatic portosystemic shunt(TIPS) and open splenectomy and esophagogastric devascularization(OSED) are widely used to treat patients with portal hypertension and recurrent variceal bleeding(PHRVB). This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB.METHODS: The data were retrospectively retrieved from 479 cirrhotic patients(Child-Pugh A or B class) with PHRVB, who had undergone TIPS(TIPS group) or OSED(OSED group) between January 1, 2010 and October 31, 2014.RESULTS: A total of 196 patients received TIPS, whereas 283 underwent OSED. Within one month after TIPS and OSED, the rebleeding rates were 6.1% and 3.2%, respectively(P=0.122). Significantly lower incidence of pleural effusion,splenic vein thrombosis, and pulmonary infection, as well as higher hepatic encephalopathy rate, shorter postoperative length of hospital stay, and higher hospital costs were observed in the TIPS group than those in the OSED group. During the follow-up periods(29 months), significantly higher incidences of rebleeding(15.3% vs 4.6%, P=0.001) and hepatic encephalopathy(17.3% vs 3.9%, P=0.001) were observed in the TIPS group than in the OSED group. The incidence of instent stenosis was 18.9%. The survival rates were 91.3% in the TIPS group and 95.1% in the OSED group. The long-term liver function did not worsen after either TIPS or OSED.CONCLUSION: For the patients with liver function in the Child-Pugh A or B class, TIPS is not superior over OSED in terms of PHRVB treatment and rebleeding prevention.
文摘AIM:To determine if liver stiffness(LS) measurements by means of transient elastography(TE) correlate with the presence of significant esophageal varices(EV) and if they can predict the occurrence of variceal bleeding.METHODS:We studied 1000 cases of liver cirrhosis divided into 2 groups:patients without EV or with grade 1 varices(647 cases) and patients with significant varices(grade 2 and 3 EV)(353 cases).We divided the group of 540 cases with EV into another 2 subgroups:without variceal hemorrhage(375 patients) and patients with a history of variceal bleeding(165 cases).We compared the LS values between the groups using the unpaired t-test and we established cut-off LS values for the presence of significant EV and for the risk of bleeding by using the ROC curve.RESULTS:The mean LS values in the 647 patients without or with grade 1 EV was statistically significantly lower than in the 353 patients with significant EV(26.29 ± 0.60 kPa vs 45.21 ± 1.07 kPa,P < 0.0001).Using the ROC curve we established a cut-off value of 31 kPa for the presence of EV,with 83% sensitivity(95%CI:79.73%-85.93%) and 62% specificity(95% CI:57.15%-66.81%),with 76.2% positive predictive value(PPV)(95% CI:72.72%-79.43%) and 71.3% negative predictive value(NPV)(95% CI:66.37%-76.05%)(AUROC 0.7807,P < 0.0001).The mean LS values in the group with a history of variceal bleeding(165 patients) was statistically significantly higher than in the group with no bleeding history(375 patients):51.92 ± 1.56 kPa vs 35.20 ± 0.91 kPa,P < 0.0001).For a cut-off value of 50.7 kPa,LS had 53.33% sensitivity(95% CI:45.42%-61.13%) and 82.67% specificity(95% CI:78.45%-86.36%),with 82.71% PPV(95% CI:78.5%-86.4%) and 53.66% NPV(95% CI:45.72%-61.47%)(AUROC 0.7300,P < 0.0001) for the prediction of esophageal bleeding.
文摘AIM:To investigate glue extrusion after endoscopic N-butyl-2-cyanoacrylate injection on gastric variceal bleeding and to evaluate the long-term efficacy and safety of this therapy.METHODS:A total of 148 cirrhotic patients in our hospital with esophagogastric variceal bleeding(EGVB) were included in this study.N-butyl-2-cyanoacrylate was mixed with lipiodol in a 1:1 ratio and injected as a bolus of 1-3 mL according to variceal size.Patients underwent endoscopic follow-up the next week,fourth week,second month,fourth month,and seventh month after injection and then every 6 mo to determine the cast shape.An abdominal X-ray fi lm and ultrasound or computed tomographic scan were also carried out in order to evaluate the time of variceal disappearance and complete extrusion of the cast.The average follow-up time was 13.1 mo.RESULTS:The instantaneous hemostatic rate was 96.2%.Early re-bleeding after injection in 9 cases(6.2%) was estimated from rejection of adhesive.Late re-bleeding occurred in 12 patients(8.1%) at 2-18 mo.The glue cast was extruded into the lumen within one month in 86.1% of patients and eliminated within one year.Light erosion was seen at the injection position and mucosa edema in the second week.The glue casts were extruded in 18 patients(12.1%) after one week and in 64 patients(42.8%) after two weeks.All kinds of glue clumping shapes and colors on endoscopic examination were observed in 127 patients(86.1%) within one month,including punctiform,globular,pillar and variform.Forty one patients(27.9%) had glue extrusion after 3 mo and 28 patients(28.9%) after six months.The extrusion time was not related to the injection volume of histoacryl.Obliteration was seen in 70.2%(104 cases) endoscopically.The main complication was re-bleeding resulting from extrusion.The prognosis of the patients depended on the severity of the underlying liver disease.CONCLUSION:Endoscopic injection of cyanoacrylate is highly effective for gastric varices bleeding.The glue clump shape is correlated with anatomic structure of vessels.The time of extrusion was not related to dosage of the glue.
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.
