432 DIGITAL SINGLE-OPERATOR CHOLANGIOSCOPY INTEROBSERVER STUDY USING A NEW AND PRACTICAL SCORING SYSTEM: THE MENDOZA CLASSIFICATION

Abstract:

Background Digital single-operator cholangioscopy (DSOC) allows direct visualization of the biliary tree for evaluation of biliary strictures. However, some criteria from the existing two sets of criteria to evaluate indeterminate biliary strictures: the Monaco criteria and the criteria in Carlos Robles-Medranda’s publication (CRM); suffer from poor interobserver agreement (IOA) thus affecting the overall diagnostic accuracy. Our objective was to assess the IOA of DSOC interpretation for indeterminate biliary strictures using a new classification system named the Mendoza criteria. Methods A reference video atlas was created containing video clips and images of 5 criteria based on expert opinion and prior studies. A total of 50 de-identified DSOC video clips were then sent to 14 interventional endoscopists with experience in cholangioscopy. They were asked to score the videos based on the presence following criteria: 1 …
