BackgroundThis study investigated the incidence and predictors of retreatment after discontinuation of either entecavir (ETV) or tenofovir disoproxil fumarate (TDF) treatment in Taiwan.MethodsA total of 535 non-cirrhotic chronic hepatitis B (CHB) patients undergoing either ETV (n = 358) or TDF (n = 177) treatment were enrolled. Patients were followed for at least 12 months after stopping ETV or TDF treatment. Most patients (86.3%) fulfilled the retreatment criteria of Taiwan's National Health Plan.ResultsThe 5-year cumulative rates of clinical relapse and retreatment were 52.1% and 47%, respectively, in 160 hepatitis B e antigen (HBeAg)-positive patients, and were 62% and 54.8%, respectively, in 375 HBeAg-negative patients. The median duration from the end of treatment until clinical relapse and retreatment was 40 and 57 weeks, respectively, for all patients. Multivariate Cox regression analysis revealed that discontinuing TDF treatment, old age, male gender, and higher baseline HBsAg levels were independent factors of retreatment in HBeAg-positive patients; old age, HBV genotype B, and higher baseline and end-of-treatment HBsAg levels were independent factors in HBeAg-negative patients. A total of 18.8% of retreated patients satisfied the retreatment criteria of hepatic decompensation according to Taiwan's National Health Plan. Of the 64 patients who had clinical relapse without retreatment, 17 achieved sustained virological remission and 26 did not experience clinical relapse until their last visit after clinical relapse. Four patients developed HBsAg loss.ConclusionsThe 5-year retreatment rate was about 50% in HBeAg-positive and HBeAg-negative patients. Discontinuing TDF treatment was an independent factor of retreatment in HBeAg-positive patients.
Background: In this study, we aimed to compare the efficacy and safety of removing a single-stage, retrograde, endoscopic common bile duct stone in patients with mild and moderate acute cholangitis associated with choledocholithiasis.Methods: We enrolled 196 endoscopic retrograde cholangiopancreatography (ERCP)-naïve patients diagnosed with acute cholangitis and choledocholithiasis between September 2018 and February 2020 at a single hospital. For eligible patients, single-stage treatment involved stone removal at initial ERCP. Early ERCP was defined as ERCP performed ≤ 72 hours following diagnosis in the emergency room.Results: The final analysis included 138 patients. The success rate of complete stone extraction was similar in patients with mild and moderate cholangitis (88.5% vs. 91.7%; p = 0. 536). Complication rates were also comparable between the two groups. In the moderate cholangitis group, the length of hospitalization declined significantly among patients who underwent early single-stage ERCP (10.6 ± 6.1 vs. 18.7 ± 12.5 days; p = 0.001) compared with patients treated with delayed ERCP. In the multivariate analysis, early ERCP indicated shorter hospitalization times (≤ 10 days) (odds ratio (OR), 7.689; p = 0.030), while endoscopic retrograde biliary drainage, for acute cholangitis only, indicated longer hospitalization times (OR, 0.358; p = 0.030). A stone size larger than 1.5 cm was an independent risk factor for stone extraction failure (OR, 24.507; p = 0.009).Conclusions: Single-stage, retrograde, endoscopic common bile duct stone removal may be safe and effective for patients with mild and moderate cholangitis. The benefit of early single-stage ERCP (≤ 72 hours) was reflected mainly by reduced hospitalization time and costs.Trial registration: ClinicalTrials.gov: NCT03754491.
Endoscopic polypectomy has become standard in the management of most polyps in the gastrointestinal tract, but bleeding is the most common adverse event. Polypectomy with a cold snare (CSP) has been increasingly utilized in recent years, but further evidence is required to establish its safety of gastric polypectomy. The aim of this study was to compare intraprocedure and postprocedure adverse events in patients who underwent CSP vs conventional hot snare polypectomy (HSP) of gastric polyps. Electronic medical records and endoscopy reports of all patients who underwent gastric polypectomy at the Kaohsiung Chang Gung Memorial Hospital between January 2019 and June 2021 were retrospectively reviewed. Data on patient demographics, polyp characteristics, method of polypectomy, and adverse events were collected. A total of 193 gastric polyps removed from 111 patients were reviewed. The mean age was 58.1 years, and 74.8% were female. Of these, 142 polyps were removed from 78 patients by HSP, compared to 51 polyps removed from 33 patients by CSP. The mean polyp size was 7.9 mm in the HSP group and 7.5 mm in the CSP group (P = .306). Nine patients (11.5%) from HSP group and 5 (15.2%) from CSP group presented with immediate bleeding that were managed by endoscopic treatment (P = .755). There was no serious adverse event, such as delayed bleeding or perforation, occurred in this study. In multivariate logistic regression, only the number of polyps resected >1 was identified as independent risk factor of immediate post‐polypectomy bleeding. Therefore, the safety of CSP was non‐inferior to HSP and could be an additional option for removal of gastric polyps ≤10 mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
