Early (<4 weeks) versus standard (≥4 weeks) endoscopic drainage of pancreatic walled-off fluid collections: a systematic review and meta-analysis
Previous studies have demonstrated that the ideal time for drainage of walled-off pancreatic fluid collections is 4 to 6 weeks after their development. However, some pancreatic collections, notably infected pancreatic fluid collections, require earlier drainage. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. The aim of this study was to evaluate the clinical efficacy and safety of EUS-guided drainage of pancreatic fluid collections <4 weeks after development compared with ≥4 weeks after development.Pooled rates of adenoma detection by colonoscopy in asymptomatic average-risk individuals with positive fecal immunochemical test: a systematic review and meta-analysis
Current adenoma detection rate (ADR) benchmarks for colonoscopy in individuals positive for a fecal immunochemical test (FIT) are ≥45% in men and ≥35% in women. These are based on weak, low-quality evidence. We performed a meta-analysis to ascertain the pooled ADR in FIT-positive colonoscopy.Comparative efficacy of different methods for difficult biliary cannulation in ERCP: systematic review and network meta-analysis
Several methods with variable efficacy have been proposed for difficult biliary cannulation in ERCP. We assessed the comparative efficacy of different strategies for difficult biliary cannulation through a network meta-analysis combining direct and indirect treatment comparisons.Endoscopic band ligation in the treatment of gastric antral vascular ectasia: a systematic review and meta-analysis
Gastric antral vascular ectasia (GAVE) is typically treated by endoscopic thermal therapies. Endoscopic band ligation (EBL) has been reported in the treatment of GAVE with encouraging results. However, EBL is not widely used to this end.Efficacy and histologic accuracy of underwater versus conventional endoscopic mucosal resection for large (>20 mm) colorectal polyps: a comparative review and meta-analysis
Major limitations with conventional EMR (C-EMR) include high rates of polyp recurrence and low en-bloc resection rates, especially for lesions >20 mm in size. Underwater EMR (U-EMR) has emerged as an alternate technique for en-bloc resection of larger lesions. We conducted a systematic review and meta-analysis comparing the efficacy and safety of the 2 techniques.Risk of progression in Barrett’s esophagus indefinite for dysplasia: a systematic review and meta-analysis
Risk of progression in Barrett's esophagus (BE) with low-grade dysplasia (LGD) and high-grade dysplasia (HGD) has been established. However, the natural history of BE with indefinite dysplasia (BE-IND) remains unclear. We performed a systematic review and meta-analysis to estimate the pooled risk of progression to HGD and/or esophageal adenocarcinoma (EAC) in BE-IND.Efficacy and safety of EUS-guided liver biopsy: a systematic review and meta-analysis
EUS-guided liver biopsy (LB) is an emerging technique over conventional percutaneous (PC) or transjugular (TJ) approaches. Recent studies have reported that EUS-guided LB may have a better safety profile than PC LB or TJ LB without compromising diagnostic yield, and the outcomes are varied with respect to the types of biopsy needles. We performed a systematic review and meta-analysis to estimate the diagnostic yield, specimen adequacy, and adverse events associated with EUS-guided LB.
