Background And Aims: Endocuff improves detection at colonoscopy but seems to impede terminal ileal (TI) intubation. We assessed the impact of Endocuff Vision (EV) on TI intubation using adult or pediatric colonoscopes and evaluated whether filling the cecum with gas versus water affected the impact of EV on TI intubation.
Methods: Using a prospectively recorded quality control database, we explored the impact of EV on TI intubation in ≤1 minute.
Background: Colorectal adenoma prevalence can be determined by autopsy studies, or imaging studies such as colonoscopy. We describe the prevalence of colorectal adenomas determined by a single high detecting colonoscopist using high definition colonoscopes.
Methods: We conducted a cross-sectional study of consecutive patients aged ≥18 years undergoing colonoscopy with a high level detector for the indications of screening, surveillance, and diagnostic reasons from December 29, 2016 to January 12, 2018.
Background And Aims: Endocuff (Arc Medical Design, Leeds, UK) and Endocuff Vision (Arc Medical Design, Leeds, UK) are effective mucosal exposure devices for improving polyp detection during colonoscopy. AmplifEYE (Medivators Inc, Minneapolis, Minn, USA) is a device that appears similar to the Endocuff devices but has received minimal clinical testing.
Methods: We performed a randomized controlled clinical trial using a noninferiority design to compare Endocuff Vision with AmplifEYE.
Background And Aims: Devices for flattening colon folds can improve polyp detection at colonoscopy. However, there are few data on the endoscopic ring-fitted cap (EndoRings; EndoAid, Caesarea, Israel). We sought to compare adenoma detection with EndoRings with that of standard high-definition colonoscopy.

View Article and Find Full Text PDFBackground: Diminutive colorectal polyps resected during colonoscopy are sometimes histologically interpreted as normal tissue. The aim of this observational study was to explore whether errors in specimen handling or processing account in part for polyps ≤ 3 mm in size being interpreted as normal tissue by pathology when they were considered high confidence adenomas by an experienced endoscopist at colonoscopy.
Methods: One endoscopist photographed 900 consecutive colorectal lesions that were ≤ 3 mm in size and considered endoscopically to be high confidence conventional adenomas.
Background: Efficiency is an important aspect of endoscopic practice that has received limited study. We evaluated the impact of scribing electronic pre-procedure history and physical examinations, and electronic procedure reports on endoscopist efficiency.
Methods: We used a stopwatch to measure the time between the procedures (scope out to scope in), pre-procedure patient assessment time, and procedure report generation time for 180 consecutive procedures performed by a single endoscopist with or without a scribe for recording history and physical and procedure reports.
Background And Study Aims: Mucosal exposure devices on the colonoscope tip have improved detection. We evaluated detection and procedure times in colonoscopies performed with EndoRings.
Patients And Methods: We had 14 endoscopists in a university practice trial EndoRings.
Background And Aims: Devices used to improve polyp detection during colonoscopy have seldom been compared with each other.
Methods: We performed a 3-center prospective randomized trial comparing high-definition (HD) forward-viewing colonoscopy alone to HD with Endocuff to HD with EndoRings to the full spectrum endoscopy (FUSE) system. Patients were age ≥50 years and had routine indications and intact colons.
