The optimal method of gallbladder drainage (GBD) for acute cholecystitis in nonsurgical candidates is uncertain. The aim of the current study was to conduct a network meta-analysis comparing the 3 methods of GBD (percutaneous [PT], endoscopic transpapillary [ETP], and EUS-guided).

Prophylactic clips to prevent delayed polypectomy bleeding (DPB) after endoscopic resection of large colorectal polyps remains controversial. We performed a systematic review and meta-analysis to evaluate the efficacy of prophylactic clips for preventing DPB by synthesizing the results of randomized trials.

Superficial pharyngeal cancers are being detected and treated using endoscopy in many medical facilities with increasing frequency. However, the reports focus on the hypopharynx. We identified reliable treatments by adapting the method for each region of the pharynx. Here, we introduce our methods for treating various pharyngeal regions and show their long-term results.

High-resolution microendoscopy (HRME) is an optical biopsy technology that provides subcellular imaging of esophageal mucosa but requires expert interpretation of these histopathology-like images. We compared endoscopists with an automated software algorithm for detection of esophageal squamous cell neoplasia (ESCN) and evaluated the endoscopists’ accuracy with and without input from the software algorithm.

The risk of bleeding and thromboembolic events in patients undergoing peroral endoscopic myotomy (POEM) who are receiving antithrombotic therapy is unknown. Our primary aim was to assess the safety of POEM in this patient subset. Secondary outcomes were rates of clinical success, GERD, and procedure-related outcomes.

Endoscopic submucosal dissection (ESD) is used for treating early luminal GI cancers. ESD is the standard of care in Asia, where it results in multiday admissions for observation. The goal of our study was to evaluate the safety and feasibility of same-day discharge (SDD) after ESD.

Although laparoscopic Heller myotomy (LHM) or peroral endoscopic myotomy (POEM) is highly effective, 10% to 20% of patients with achalasia remain symptomatic after treatment. In evaluating such patients, we have observed a pattern of failure associated with a pseudodiverticulum, or blown-out myotomy (BOM), in the distal esophagus. We aimed to assess risk factors and patient-reported outcomes associated with a BOM.

Volumetric laser endomicroscopy (VLE) is an advanced imaging modality used to detect Barrett’s esophagus (BE) dysplasia. However, real-time interpretation of VLE scans is complex and time-consuming. Computer-aided detection (CAD) may help in the process of VLE image interpretation. Our aim was to train and validate a CAD algorithm for VLE-based detection of BE neoplasia.
Outcomes of radiofrequency ablation by manual versus self-sizing circumferential balloon catheters for the treatment of dysplastic Barrett’s esophagus: a multicenter comparative cohort study

Radiofrequency ablation (RFA) is the preferred ablative modality for treating dysplastic Barrett’s esophagus. The recently introduced self-sizing circumferential ablation catheter eliminates the need for a sizing balloon. Although it enhances efficiency, outcomes have not been compared with the previous manual-sizing catheter. We evaluated the comparative safety and efficacy of these 2 ablation systems in a large, multicenter cohort.

Definitive chemoradiotherapy (CRT) is increasingly used as a nonsurgical treatment for esophageal cancer. In Japanese studies, salvage endoscopic resection (ER) has emerged as a promising strategy for local failure after definitive CRT. We aimed to evaluate the safety and efficacy of salvage ER in a Western setting.

Sequential endoscopist-driven phone calls improve the capture rate of adverse events after ERCP: a prospective study

Volume 93, Issue 4, April 2021, Pages 902-910.e1
ERCP is a high-risk endoscopic procedure, yet reports of ERCP-related adverse events are largely limited to early adverse events based on immediate postprocedure assessment. We hypothesize that immediate/1-day follow-up underestimates the true adverse event rate, and later follow-up calls may enable a more accurate assessment of adverse events, leading to enhanced postprocedural patient care.

The accurate measurement of technical skill in ERCP is essential for endoscopic training, quality assurance, and coaching of this procedure. Hypothesizing that technical skill can be measured by analysis of ERCP videos, we aimed to develop and validate a video-based ERCP skill assessment tool.

The potential for transmission of pathogenic organisms is a problem inherent to the current reusable duodenoscope design. Recent outbreaks of multidrug-resistant pathogenic organisms transmitted via duodenoscopes has brought to light the urgency of this problem. Microbiologic culturing of duodenoscopes and reprocessing with repeat high-level disinfection (HLD) or liquid chemical sterilization (LCS) have been offered as supplemental measures to enhance duodenoscope reprocessing by the U.S. Food and Drug Administration. This study aims to compare the efficacy of reprocessing duodenoscopes with double HLD (DHLD) versus LCS.

Various macroscopic features are proposed for the diagnosis of biliary lesions during digital single-operator cholangioscopy (DSOC); however, neovasculature may be one of the most reliable features of neoplasia. We aimed to evaluate the detection of neovasculature during DSOC to distinguish neoplastic from non-neoplastic bile duct lesions.

Duodenal endoscopic submucosal dissection (ESD) is considered technically challenging and has a high risk of adverse events. However, we recently made some progress with the ESD technique and device by introducing 2 features: a water pressure (WP) method and a second-generation ESD knife (DualKnife) with a water jet function (DualKnife J). The present study aimed to assess whether these changes improved the clinical outcomes of duodenal ESD.

Cold snare defect protrusions (CSDPs) include muscularis mucosa (MM) and submucosa tissue. CSDPs are thought to result from fragmentation of the specimen during shallow excision. Our aim in this study was to clarify whether CSDPs are associated with polyp fragmentation.

Artificial intelligence (AI)–assisted polyp detection systems for colonoscopic use are currently attracting attention because they may reduce the possibility of missed adenomas. However, few systems have the necessary regulatory approval for use in clinical practice. We aimed to develop an AI-assisted polyp detection system and to validate its performance using a large colonoscopy video database designed to be publicly accessible.
