Gastrointestinal Endoscopy

BACKGROUND AND AIMS: Patients with ulcerative colitis (UC) are at risk of developing colorectal cancer (CRC). The feasibility of endoscopic resection (ER) for UC-associated neoplasia (UCAN) has been suggested, but its efficacy and safety remain unclear. We aimed to assess the efficacy and safety of ER for colorectal neoplasms in patients with UC. METHODS: This was a retrospective, multicenter cohort study of patients with UC who initially underwent ER or surgery for colorectal neoplasms between April 2015 and March 2021...

BACKGROUND AND AIMS: Reintervention following Endoscopic sleeve gastroplasty (ESG) can be indicated due to postprocedural complications from various pre-interventional or postprocedural comorbidities. We developed and internally validated an ESG reintervention scoring system (ESGRS) that determines the individualized risk of reintervention within the first 30 days following ESG. METHODS: We used data from a sample of 3583 patients who underwent ESG in the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP) database (2016 to 2021)...

BACKGROUND AND AIMS: Endoscopic band ligation (EBL) without resection combined with a single-incision needle-knife (SINK) biopsy may have a positive impact on small gastrointestinal subepithelial tumor (SET) management, but it needs to be tested. The aim was to evaluate the feasibility of this strategy in small-sized SET. METHODS: This prospective multicenter observational cohort study in 7 centers included patients with SETs ≤15mm (confirmed by endoscopic ultrasound (EUS)) between March 2017 and March 2020...

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach to strategies to prevent endoscopy-related injury (ERI) in GI endoscopists. It is accompanied by the document subtitled METHODOLOGY AND REVIEW OF EVIDENCE: Which provides a detailed account of the methodology employed for the evidence review. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. The guideline estimates the rates, sites, and predictors of ERI...

BACKGROUND AND AIMS: EUS-guided ethanol ablation (EUS-EA) is a recently introduced treatment approach for pancreatic cystic lesions (PCLs), including branch-duct-type intraductal papillary mucinous neoplasms (BD-IPMNs). However, the utility of this procedure is limited owing to its relatively low efficacy in treating PCLs. METHODS: We retrospectively reviewed patients with PCLs, including those with enlarging suspected BD-IPMNs, or those with PCLs measuring >3cm who were suboptimal candidates for surgery and had been managed using EUS-guided rapid ethanol lavage (EUS-REL; four times of immediate ethanol lavage, 2015-2022) or surveillance-only (SO, 2007- 2022)...

BACKGROUND AND AIMS: Surveillance of gastric intestinal metaplasia (GIM) may lead to early gastric cancer detection. Our purpose was to externally validate a predictive model for endoscopic GIM previously developed in a veteran population in a second U.S. METHODS: We previously developed a pre-endoscopy risk model for detection of GIM using 423 GIM cases and 1796 controls from the Houston VA Hospital. The model included sex, age, race/ethnicity, smoking, and H. pylori infection with an area under the receiver operating characteristic (AUROC) curve of 0...

BACKGROUND AND AIMS: Stenosis after esophageal Endoscopic Submucosal Dissection (ESD) has a high incidence, and muscular injury is an important risk factor for esophageal stenosis. Hence, this study aimed to classify muscular injury degrees and investigate their association with postoperative stenosis. METHODS: This retrospective study included 1,033 patients with esophageal mucosal lesions treated with ESD between August 2015 and March 2021. Demographic and clinical parameters were analyzed, and stenosis risk factors were identified using multivariate logistic regression...

BACKGROUND AND AIMS: Endoscopist experience and center volume might be associated with endoscopic retrograde cholangiopancreatography (ERCP) outcomes, as in other fields of endoscopy and in surgery. An effort to assess this relationship is important to improve practice. This systematic review and meta-analysis aimed to evaluate these comparative data and assess the impact of endoscopist and center volume on ERCP procedure outcomes. METHODS: We performed a literature search in PubMed, Web of Science and Scopus through March 2022...

BACKGROUND AND AIM: Self-expandable metal stents (SEMS) are widely used for palliation of distal malignant biliary obstruction (dMBO). However, previous studies comparing the outcomes between uncovered (UCSEMS) and covered (FCSEMS) stents report conflicting results. This large cohort study aimed to compare the clinical outcomes between UCSEMS and FCSEMS for dMBO. METHODS: A retrospective cohort study was performed in patients with dMBO who underwent either UCSEMS or FCSEMS placement between May 2017 and May 2021...

BACKGROUND AND AIMS: Reintervention modalities following myotomy failure in achalasia patients have yet to be established. The efficacy and safety of salvage peroral endoscopic myotomy (POEM) for treatment of achalasia following a myotomy failure were evaluated in the study. METHOD: Between August 2011 to August 2021, at the Endoscopy Center of Zhongshan Hospital, 219 achalasia patients who had previously undergone a myotomy underwent a salvage POEM and were thus retrospectively enrolled in this study...

BACKGROUND AND AIMS: Transoral outlet reduction (TORe) and anti-obesity medication (AOM) are effective treatments for weight regain following Roux-en-Y gastric bypass (RYGB). This study aims to 1) assess the efficacy of combination therapy (TORe + AOM) for treating weight regain and 2) compare the safety and efficacy of combination therapy to AOM alone, TORe alone and surgical revision of RYGB. METHODS: This was a retrospective study of RYGB patients with weight regain who underwent combination therapy, defined as initiation of at least one AOM within 6 months prior to or after TORe...

BACKGROUND AND AIMS: Superficial pharyngeal squamous cell carcinoma (PSCC) has received increasing attention as a therapeutic target in the gastrointestinal field with recent innovations in endoscopic submucosal dissection (ESD). However, there are currently no defined criteria for the application of ESD to superficial PSCC. One of the problems encountered during follow-up post-ESD is cervical lymph node metastasis (LNM). Identifying the clinicopathological predictors of cervical LNM can help to provide a basis for the refinement of therapeutic strategies for superficial PSCC...
