Trial Outcomes & Findings for Fluorescent Cholangiography vs White Light for Bile Ducts Identification (NCT NCT02702843)

NCT ID: NCT02702843

Last Updated: 2025-11-12

Results Overview

Detection rate of the common bile duct during laparoscopic cholecystectomy, defined as the proportion of patients in whom the common bile duct was visualized immediately before dissection (baseline) and immediately after dissection using near infrared light. The detection rate was calculated separately for each arm and reported as the percentage of patients with successful identification.
