Clinique Paris-Bercy28 enrolled

Overview

Background and aims Digital single-operator cholangioscopy (DSOC) enhances biliary stricture diagnosis, but the collection of quality samples can be difficult due to the small diameter of the working channel. A new DSOC (EyeMAXTM 11Fr, Micro-Tech Endoscopy, Nanjing, China) with a 2.0 mm working channel, accommodating pediatric forceps (1.6 mm), has been introduced in France. This study reports on the initial French experience. Methods A retrospective multicenter observational study on DSOC was conducted across five endoscopy units within the CREGG (French Society of Private Hepato-Gastroenterology). Satisfaction and procedural evaluations were recorded using a visual analog scale (VAS) and compared with the SpyglassTM DS II DSOC (Boston Scientific).
