Outcome of individuals with alcoholic cirrhosis hospitalized with first decompensation and their predictors.

BACKGROUND OBJECTIVES: Alcohol is one of most common aetiologies of cirrhosis and decompensated cirrhosis is linked to higher morbidity and death rates. This study looked at the outcomes and mortality associated risk variables of individuals with alcoholic cirrhosis who had hospitalization with their first episode of decompensation. METHODS: Individuals with alcoholic cirrhosis who were hospitalized with the first episode of decompensation [acute decompensation (AD) or acute-on-chronic liver failure (ACLF)] were included in the study and were prospectively followed up until death or 90 days, whichever was earlier. RESULTS: Of the 227 study participants analyzed, 167 (73.56%) and 60 (26.43%) participants presented as AD and ACLF, respectively. In the ACLF group, the mortality rate at 90 days was higher than in the AD group (48.3 vs 32.3%, P=0.02). In the AD group, participants who initially presented with ascites as opposed to variceal haemorrhage had a greater mortality rate at 90 days (36.4 vs 17.1%, P=0.041). The chronic liver failure-consortium AD score and the lactate-free Asian Pacific Association for the study of the Liver-ACLF research consortium score best-predicted mortality in individuals with AD and ACLF. INTERPRETATION CONCLUSIONS: There is significant heterogeneity in the type of decompensation in individuals with alcoholic cirrhosis. We observed significantly high mortality rate among alcoholic participants hospitalized with initial decompensation; deaths occurring in more than one-third of study participants within 90 days.

Predictors of proximal migration of straight biliary plastic stents.

BACKGROUND/AIMS: Proximal biliary plastic stent migration (PSM) remains a challenging complication. The study aims at determining the PSM rate, retrieval outcomes and factors associated with PSM. METHODS: Endoscopy database was analyzed from January 2016 to January 2021 to identify 1137 patients, who underwent stent removal or repeat endoscopic retrograde cholangiopancreatography (ERCP). Demography, methods of stent retrieval, outcomes and complications were noted. Logistic regression was performed to determine risk factors for PSM. Propensity score matching was done in a 1:1 manner using age, sex, comorbidities and indication to assess endoscopy-related factors. Clinical trial registration done (CTRI/2022/02/040516). RESULTS: PSM was noted in 74 (6.5%) cases. Stent retrieval was successful in 94.59% (70/74) of cases. A balloon catheter (46/74) was commonly used. Technical failure was due to an impacted stent (2) and stent above the stricture (2). Complications were seen in 2.7% of cases. On multi-variate regression, sphincteroplasty at index ERCP (Odds ratio [OR] = 5.68, 95% confidence interval [CI] = 2.7-11.89), stent length < 10 cm (OR = 8.53, 95% CI = 3.2-22.47), 7-Fr stent (OR = 18.25, 95% CI = 6.5-50.64), dilated bile duct (mean diameter- 9.2 ± 3.94 mm) (OR = 0.384, 95% CI = 0.18-0.72) and delayed ERCP by > 3 months from index ERCP (OR = 15.28, 95% CI = 8.1-28.49). After performing propensity score matching for age, sex, comorbidities and indication to determine endoscopy-related factors, 7-Fr stent size (OR 3.495; 95% CI-1.23-9.93) and duration of indwelling stent for more than three months (OR-3.37; 95% CI-1.646-6.76) were significantly associated with proximal stent migration. CONCLUSION: Proximally migrated straight stents can be successfully retrieved using standard accessories. The use of 7-Fr size stent, stents indwelling for more than three months, sphincteroplasty at index ERCP, stent length < 10 cm and dilated bile duct were associated with increased risk of proximal migration of straight biliary plastic stents. After propensity score matching, the use of 7-Fr size stents and stent indwelling for over three months were endoscopy-related factors associated with proximal migration.

Comparison of efficacy and safety of endoscopic and radiological interventions for gastric varices: A systematic review and network meta-analysis.

Aim of the study: There is a paradigm shift in the management of gastric varices with the availability of endoscopic ultrasound and radiologic interventions. The optimal choice of intervention remains a dilemma for most treating physicians. Material and methods: We searched MEDLINE, the Cochrane Central Register of Controlled Trials, and ScienceDirect for studies comparing endoscopic glue injection, endoscopic thrombin injection (THB), variceal band ligation, EUS-guided coiling, EUS-guided glue injection, EUS-guided coiling with glue (EUS-C+G), balloon occluded retrograde transvenous obliteration (BRTO), and transjugular intrahepatic portosystemic shunt (TIPS) for gastric varices in adults. The data on four outcomes - obliteration of varices, rebleeding, adverse effects, and mortality - were pooled using a random-effects model. Treatment estimates were calculated as odds ratios (ORs) along with their 95% confidence interval (CI). The relative ranking of interventions for various outcomes was calculated as their surface under the cumulative ranking curve (SUCRA). Results: We identified 34 studies (10 randomized controlled trials, 24 non-randomized trials) with 2783 patients. Based on SUCRA plots, BRTO (SUCRA 95.1) had the highest rate of variceal obliteration followed by EUS-C+G (SUCRA 80.9). The risk of rebleeding was lowest with BRTO (SUCRA 85.1) followed by EUS-C+G (SUCRA 78.8). Moderate-severe adverse effects were least likely with THB (SUCRA 92.5) and highest with TIPS (SUCRA 3.7). In terms of mortality, EUS-C+G (73.5) had the lowest probability of overall mortality followed by TIPS (69.1). Conclusions: In this network meta-analysis, we found BRTO and EUS-guided therapies to be superior to endoscopic glue injection. However, the level of evidence remains low.

DAPS score - a novel score for prediction of significant fibrosis in incidentally detected asymptomatic hepatitis B subjects.

Aim of the study: Significant fibrosis is an indication for treatment in hepatitis B patients with normal transaminase levels. The present study was aimed at analyzing the factors associated with significant fibrosis in incidentally detected asymptomatic hepatitis B subjects (IDAHS) and developing a model for fibrosis prediction for use in low-resource settings. Material and methods: This is a single-center retrospective analysis of data on IDAHS who had undergone FibroScan. The variables associated with significant fibrosis in the derivation cohort were subjected to multivariate analysis by logistic regression. The model was applied to the validation cohort for fibrosis prediction. Results: A total of 299 patients (mean age: 42.6 years, males: 63.2%) were included in the model derivation. Significant fibrosis was found in 27.4% (82/299) of the patients and 16.8% (30/178) of those with normal transaminase. On multivariate analysis, age, lower platelet count, and presence of diabetes were associated with fibrosis. Serum glutamic pyruvic transaminase (SGPT) was included in the model as it was nearing towards in multivariate analysis. The DAPS (diabetes, age, platelet count, SGPT) score was proposed with equal weightage to each variable. Based on the cumulative score, patients were categorized as having low risk (DAPS score 0-2) or high risk (DAPS score 3-4). The specificity of the model in derivation and validation cohorts was 98.2% and 97.6%, respectively, while the accuracy was 83.6% and 80%, respectively. Conclusions: Approximately 17% of IDAHS with normal transaminase have significant fibrosis. The DAPS score can be used easily as a bedside tool for assessment of significant fibrosis in IDAHS with excellent specificity.

Outcomes of thin versus thick-wire snares for cold snare polypectomy: a systematic review and meta-analysis.

BACKGROUND/AIMS: Cold snare polypectomy (CSP) is commonly used for the resection of colorectal polyps ≤10 mm. Data regarding the influence of snare type on CSP effectiveness are conflicting. Hence, this meta-analysis aimed to compare the outcomes and safety of thin- and thick-wire snares for CSP. METHODS: A comprehensive search of the literature published between 2000 and 2021 was performed of various databases for comparative studies evaluating the outcomes of thin- versus thick-wire snares for CSP. RESULTS: Five studies with data on 1,425 polyps were included in the analysis. The thick-wire snare was comparable to the thin-wire snare with respect to complete histological resection (risk ratio [RR], 1.03; 95% confidence interval [CI], 0.97-1.09), overall bleeding (RR, 0.98; 95% CI, 0.40-2.40), polyp retrieval (RR, 1.01; 95% CI, 0.97-1.04), and involvement of submucosa in the resection specimen (RR, 1.28; 95% CI, 0.72-2.28). There was no publication bias and a small study effect, and the relative effects remained the same in the sensitivity analysis. CONCLUSION: CSP using a thin-wire snare has no additional benefit over thick-wire snares in small colorectal polyps. Factors other than snare design may play a role in improving CSP outcomes.

Intra- and inter-observer agreement in the classification of dyssynergic defecation on high-resolution anorectal manometry using water-perfusion system.

BACKGROUND AND AIMS: Dyssynergic defecation (DD) classified on anorectal manometry is based on variations in anal sphincter pressures and rectal pressure generated during bearing down. There is a paucity of data on intra- and inter-observer agreement in the classification of DD on high-resolution anorectal manometry (HRAM) using a water-perfusion system. METHODS: This cross-sectional observational study was conducted between June 2014 and May 2016 on 70 adult patients with DD. Observer 1 did the baseline analysis and reanalyzed the readings at least 6 months later, blinded to the initial analysis results (intra-observer variability). Four other blinded observers (5-25 years in anorectal manometry and minimum 5 years of experience in HRAM) then individually analyzed the manometry data (inter-observer variability). RESULTS: Intra-observer agreement was excellent (kappa 0.862) for classifying DD. Agreement between the six observations (i.e. two from observer 1 and four from independent observers) was also good (kappa 0.632). The highest agreement was for type 4 DD (kappa 0.738), followed by type 1 (0.680), type 2 (0.664), and type 3 (0.537). Cronbach's alpha value was 0.93, suggesting excellent internal consistency. CONCLUSION: The diagnosis of the types of DD on anorectal manometry using a water-perfusion system has excellent intra-observer and good inter-observer agreement .

Adverse Events with D-penicillamine Therapy in Hepatic Wilson's Disease: A Single-Center Retrospective Audit.

BACKGROUND AND OBJECTIVE: There are limited data on the adverse events of D-penicillamine in Wilson's disease (WD) that can result in dose modification or treatment discontinuation. The objective of this study was to observe the adverse events related to D-penicillamine in patients with hepatic WD. METHODS: A retrospective audit of prospectively registered hepatic WD patients at a tertiary care center between December 2006 and January 2020 was carried out. Demographic variables, laboratory parameters, and details of treatment were noted. Adverse events (AEs) related to D-penicillamine treatment, the timing and management of these AEs were analysed. RESULTS: The study included 112 patients with hepatic WD on D-penicillamine. D-penicillamine intolerance was seen in 28/112 (25%) over 179 person-years. Of the 28 AEs, severe AEs leading to permanent D-penicillamine discontinuation occurred in 16 (57%) [never reintroduced 12 (43%), discontinued after intolerant to rechallenge, 4 (14%)], temporary cessation followed by reintroduction to initial dose 13 (46%) and continuation with reduced dose in 3 (11%) patients. Overall, most common AEs were hematological [16, 57% (pancytopenia n = 8, bicytopenia n = 5 and hemolytic anemia n = 3)] while renal adverse events (n = 7, 25%) constituted the most common indication for permanent discontinuation. Cytopenias developed beyond 12 months of D-penicillamine initiation whereas hemolytic anemia developed within first 3 months. Following D-penicillamine discontinuation in 25 patients, it was reintroduced to initial dose in 13/25 (52%), switched to trientine due to neurological worsening in 2/25 (8%) and switched to zinc in 10/25 (40%). In patients with reintroduction, gradual dose escalation was tolerated in 9/13 (69%) with a recurrence of AEs leading to permanent discontinuation in 4/13 (31%). CONCLUSION: D-penicillamine treatment is associated with significant AEs mainly related to blood, kidney, and skin. Temporary cessation of drug with reintroduction at a lower dose is an effective and safe option.

Outcomes of Endoscopic Management among Patients with Bile Leak of Various Etiologies at a Tertiary Care Center.

BACKGROUND/AIMS: Bile leak is a common complication of cholecystectomy, and it is also observed in other conditions such as ruptured liver abscess, hydatid cyst, and trauma. Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line management for such conditions. However, studies on the outcomes of endoscopic management for bile leaks with etiologies other than post-cholecystectomy injury are extremely limited. METHODS: We conducted a retrospective review of patients with symptomatic bile leak who were referred to a tertiary care center and who underwent ERCP between April 2016 and April 2019. The primary outcome was complete symptomatic resolution without extravasation of the contrast medium during the second ERCP conducted after 6 weeks. RESULTS: In total, 71 patients presented with symptomatic bile leak. The etiologies of bile leak were post-cholecystectomy injury in 34 (47.8%), liver abscess in 20 (28.1%), and post-hydatid cyst surgery in 11 (15.4%) patients. All patients were managed with ERCP, sphincterotomy, and stent placement for 6 weeks, except for one who underwent surgery. The primary outcome was achieved in 65 (91.5%) of 71 patients. There was no significant difference in terms of outcome in relation to the interval between the diagnosis of bile leak and ERCP. CONCLUSION: Most patients with bile leak can be successfully managed with ERCP even when performed on an elective basis.
