Observational data on the impact of on-site cytopathology evaluation (OCE) during endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) pancreatic masses have reported conflicting results. We aimed to compare diagnostic yield malignancy and proportion inadequate specimens between patients undergoing EUS-FNA with without OCE.In this multicenter randomized controlled trial, consecutive solid mass underwent randomization for or OCE. The number FNA passes in OCE+ arm was dictated by...
Per oral pancreatoscopy (POP) with electrohydraulic lithotripsy (EHL) or laser (LL) permits stone fragmentation and removal during endoscopic retrograde cholangiopancreatography. Our study evaluates the safety efficacy of POP in patients main pancreatic duct (PD) stones.This was a cohort undergoing EHL/LL for PD stones between January 2000 March 2011. Technical success defined as complete partial clearance, clinical greater than 50% reduction opiate use, pain, hospitalizations.Forty-six...
Performing endoscopic retrograde cholangiopancreatography (ERCP) in surgically altered gastrointestinal anatomy remains challenging, frequently necessitating the use of forward-viewing endoscopes. Given challenge endoscope selection based on type anatomy, aim this study was to examine ERCP success rates by specific endoscopes for different types. This single-center retrospective examined ERCPs performed patients with during an 18-year period. Enteroscopy success, cannulation and intervention...
To study the clinical, endoscopic, sonographic, and cytologic features of ectopic pancreas (EP).This was a retrospective performed at an academic referral center including two hospitals. Institutional review board approval obtained. Patients referred to University Hospital or Denver Health Medical Center Gastrointestinal Endoscopy Lab for gastroduodenal subepithelial lesions (SEL) with final diagnosis EP between January 2009 December 2013 were identified. in this group selected if they...
Budd-Chiari syndrome is an uncommon cause of liver failure usually associated with underlying hypercoagulable state.To evaluate current trends in management at our institution.Twenty-two patients underwent transjugular intrahepatic porto-systemic shunt, transplantation, or both between 1992 and 2001. We analysed diagnosis, medical therapy, complications, follow-up overall outcomes.Five (17%) presented fulminant 17 (83%) new-onset ascites chronic disease. Seventeen (74%) shunt: improvement...
Pancreatic duct stones contribute to pain in patients with chronic pancreatitis, and per-oral pancreatoscopy (POP) allows visualization, fragmentation, removal of these stones. This study compared the safety efficacy endoscopic retrograde pancreatography (ERP) without POP.This single-center retrospective review ERP POP for treatment main-duct pancreatic The primary outcome was technical success, defined as partial or complete stone removal, which between 2 groups.In all, 223 underwent 549...
Endoscopic ultrasound with fine needle aspiration (EUS-FNA) has become the standard of care in evaluation solid pancreatic lesions. Limited data exist on interobserver agreement (IOA) among cytopathologists assessing EUS-FNA specimens. This study aimed to evaluate IOA cytology specimens lesions using a novel standardized scoring system and assess individual clinical cytologic predictors IOA.Consecutive patients who underwent at tertiary referral center were included. slides evaluated by four...
Abstract Introduction Iatrogenic esophageal perforation (IEP) is a severe adverse event (AE) of upper endoscopy procedures (UEPs) associated with morbidity. Management has shifted from surgery to endotherapy clip closure (CC), self-expanding metal stent (SEMS), and vacuum therapy (VT). Limited analyses measure outcomes during contemporary interventional periods. Methods IEPs EGD, EUS, small bowel enteroscopy (SBE), ERCP at 3-hospital academic center January 2011 December 2023 were identified...
Objectives: Advanced ERCP techniques (AETs) for difficult biliary stones include peroral cholangioscopy (POC) with electrohydraulic/laser lithotripsy (EHL/LL), endoscopic papillary large balloon dilation (EPLBD) and mechanical (ML). We assess the efficacy of AETs.Methods: A retrospective query AETs. Primary outcome: Complete duct clearance. Secondary clearance by technique. Statistical Analysis version 9.3 (SAS Inc., Cary, NC).Results: From 1/00 to 10/12, 349 patients were identified which...
Objectives Data regarding the safety of endoscopic retrograde pancreatography (ERP) are limited compared with biliary cholangiopancreatography. The aim this study was to determine adverse events (AEs) associated therapeutic ERP. Methods This single-center retrospective examined consecutive ERPs primary intention cannulating pancreatic duct. Multivariate logistic regression performed identify risk factors for AEs. Results A total 3023 were in 1288 patients (mean age, 50.3 years; 57.8% female)...
