Impact of COVID-19 on gastroenterology fellowship training: a multicenter analysis of endoscopy volumes.

The COVID-19 pandemic has had a profound impact on gastroenterology training programs. We aimed to objectively evaluate procedural training volume and impact of COVID-19 on gastroenterology fellowship programs in the United States. This was a retrospective, multicenter study.

Endoscopic ultrasound-guided gastroenterostomy using large-diameter (20 mm) lumen apposing metal stent (LLAMS).

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using a 15-mm lumen apposing metal stent (LAMS) has emerged as a viable alternative to surgical gastrojejunostomy for management of gastric outlet obstruction (GOO). However, given the size of the anastomosis created with a 15-mm LAMS, long-term luminal patency and clinical outcomes may be suboptimal. The aim of this study was to evaluate the technical feasibility, efficacy, and safety of EUS-GE with a large-diameter (20 mm) LAMS (LLAMS).

Impact of feedback on adenoma detection rate: a systematic review and meta-analysis.

Background: Adenoma detection rate (ADR) is one of the most important quality indicators of colonoscopy. Monitoring endoscopists and providing feedback has shown to improve ADR. We performed a systematic review of the literature and meta-analysis to determine the effect of any form of feedback on ADR.

Molecular analysis of EUS-acquired pancreatic cyst fluid for KRAS and GNAS mutations for diagnosis of intraductal papillary mucinous neoplasia and mucinous cystic lesions: a systematic review and meta-analysis.

Background And Aims: Although molecular analysis of pancreatic cyst fluid may aid pancreatic cyst classification, clinical practice remains highly variable. Therefore, we performed a systematic review and meta-analysis to evaluate the diagnostic performance of KRAS and GNAS mutations in EUS-acquired pancreatic cyst fluid for diagnosis of intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic lesions (MCLs).

Methods: Individualized searches were developed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines and meta-analysis analyzed according to the Cochrane Diagnostic Test Accuracy working group methodology.

Balloon-Occluded Retrograde Transvenous Obliteration (BRTO) Versus Transjugular Intrahepatic Portosystemic Shunt (TIPS) for Treatment of Gastric Varices Because of Portal Hypertension: A Systematic Review and Meta-Analysis.

Background: Although gastric variceal (GV) bleeding is less common than esophageal variceal bleeding, the severity of GV bleeding is often greater with higher morbidity and mortality rates. Minimally invasive endovascular treatments such as balloon-occluded retrograde transvenous obliteration (BRTO) and transjugular intrahepatic portosystemic shunt (TIPS) have been used for the management of GVs with varying results, and individual and institutional differences exist in the use of BRTO and TIPS. We performed a systematic review and meta-analysis to compare the feasibility, efficacy, and safety of BRTO and TIPS for the treatment of GVs because of portal hypertension.

Temporal relationships between esophageal injury type and progression in patients undergoing atrial fibrillation catheter ablation.

Background: Currently, little is known about the onset, natural progression, and management of esophageal injuries after atrial fibrillation (AF) ablation.

Objectives: We sought to provide a systematic review on esophageal injury after AF ablation and identify temporal relationships between various types of esophageal lesions, their progression, and clinical outcomes.

Methods: A comprehensive search of PubMed and Web of Science was conducted until September 21, 2017.

Impact of sustained viral response postcurative therapy of hepatitis C-related hepatocellular carcinoma: a systematic review and meta-analysis.

Antiviral therapy with interferon based therapies (IBT) has shown potential in improving survival in patients who have undergone resection or locoregional therapy for hepatitis C-associated hepatocellular carcinoma (HCV-HCC). However, this benefit has not been definitively ascribed to sustained viral response (SVR). Since IBT has been replaced with new directly acting agents (DAA), which are more efficacious in the treatment of HCV, we sought to better determine the prognostic impact of SVR in HCV-HCC.
