BACKGROUND AND AIMS: 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. METHODS: Gastroenterologists from Europe and the United States were invited to submit their experience with salvage endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) after definitive CRT...

BACKGROUND AND AIMS: 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. Microbiological culturing of duodenoscopes and reprocessing with repeat high-level disinfection or liquid chemical sterilization have been offered as supplemental measures to enhance duodenoscope reprocessing by the U...

BACKGROUND AND AIMS: Artificial intelligence (AI)-assisted polyp detection systems for colonoscopic use are currently attracting attention because they may reduce the possibility of adenomas being missed. 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. METHODS: To develop the deep learning-based AI system, 56,668 independent colonoscopy images were obtained from 5 centers for use as training images...

BACKGROUND AND AIMS: 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. METHODS: Based on review of procedural videos, the task of ERCP was deconstructed into its basic components by an expert panel that developed an initial version of the Bethesda ERCP Skill Assessment Tool (BESAT)...

BACKGROUND AND AIMS: Loop formation can impede scope advancement, destabilize the tip and cause pain. Strategies to mitigate looping include torque-based reduction maneuvers, variable stiffness shafts and abdominal splinting. In some cases, these strategies are insufficient and there is need for novel instruments. Loop formation is of particular concern in colonoscopy, but it can also impact performance of other endoscopic procedures such as enteroscopy and altered-anatomy ERCP. In this case series we demonstrate the utility of a novel rigidizing overtube (Pathfinder, Neptune Medical, Burlingame, Calif, USA) in colonoscopy and other endoscopic procedures where loop management is critical...

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is the preferred ablative modality for treating dysplastic Barrett's esophagus (BE). 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. METHODS: Patients undergoing RFA at 3 tertiary care centers from 2005 to 2018 were included...

BACKGROUND AND AIMS: 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 aid in the process of VLE image interpretation. Our aim was to train and validate a CAD algorithm for VLE-based detection of BE neoplasia. METHODS: The multicenter, VLE PREDICT study, prospectively enrolled 47 BE patients...

BACKGROUND AND AIMS: Endoscopic treatment is recommended for low-grade dysplasia (LGD), high-grade dysplasia (HGD), and colorectal cancer (CRC) with submucosal (SM) invasion <1000 μm. However, diagnosis of invasion depth requires experience and is often difficult. This study developed and evaluated a novel computer-aided diagnosis (CAD) system to determine whether endoscopic treatment is appropriate for colorectal lesions using only white-light endoscopy (WLE). METHODS: We extracted 3442 images from 1035 consecutive colorectal lesions (105 LGDs, 377 HGDs, 107 CRCs with SM <1000 μm, 146 CRCs with SM ≥1000 μm, and 300 advanced CRCs)...

BACKGROUND AND AIMS: Cold snare defect protrusions (CSDPs) include muscularis mucosa (MM) and submucosa (SM) 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 in fact associated with polyp fragmentation. METHODS: We retrospectively analyzed 1026 neoplastic colorectal polyps resected by cold snare polypectomy from which the presence or absence of CSDPs was assessed from the endoscopic image...

Yuri Hanada, Kenneth K Wang
BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is a technique used for treating early luminal gastrointestinal cancers. ESD is 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. METHODS: This is a retrospective cohort study of adults who underwent similar esophageal ESD with a Clutch Cutter device (DP2618DT; Fujifilm) at Mayo Clinic (Rochester, Minn, USA) from 2017 to 2019 with a single endoscopist...

BACKGROUND AND AIMS: Superficial pharyngeal cancers are being detected and treated using endoscopy in many medical facilities with increasing frequency. However, those 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. METHODS: Out of 308 consecutive patients who underwent pharyngeal ESD between February 2007 and December 2018 at our institution, we selected for this study 294 that were histologically diagnosed with squamous cell carcinoma...

Monique T Barakat, Subhas Banerjee
BACKGROUND AND AIMS: 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. METHODS: Consecutive patients undergoing ERCP at our tertiary care academic medical center from 2018 to 2019 were analyzed...
