Proposal of a Macroscopic Classification for Tissular Lesions of the Bile Duct Detected During Peroral Cholangioscopy (POCS): 12

Abstract:

AIM: To propose a macroscopic classification of bile duct tissular lesions for differentiation between benign and malignant lesions. Methods: Ambispective study. Retrospective stage (Sept/2013-Sept/2015) was performed in patients evaluated by POCS (SpyGlass® legacy and DS). Exclusion criteria: absence of histology confirmation and/or absence of POCS at 6 months follow-up (for benign lesions). To determine macroscopic classification, all patients records were evaluated. 315 images were analyzed and classified as benign or malignant by an expert with> 140 POCS cases, and compared to histology. Based on morphological and vascular pattern, lesions were classified as follow on table 1. Inter-observer and intra-observer agreement was calculated using 40 random lesions images (1 expert, 2 non-expert in POCS). Prospective stage (non randomized, double blind, Oct/2015-April/2016) evaluated diagnostic …
