Retrospective analysis reveals low IOC usage in cholecystectomy, suggesting need for enhanced surgical education.

The study aims to quantify the use of intraoperative cholangiography (IOC) and evaluate its implications for surgical training.
Retrospective analysis of all cholecystectomies performed at a visceral surgery centre from July 2015 to June 2023.
Assessment of national data on IOC usage from the Federal Statistical Office (2015–2021).
Comparison of local IOC data with national trends and international recommendations.
IOC was performed in 34 out of 1,313 cholecystectomies (2.6%), primarily for clarifying biliary anatomy.
The conversion rate at the centre was 1.4%, with a major bile duct injury incidence of 0.07%.
Nationally, the use of IOC showed a decreasing trend over the observation period.

Schwarz et al. (2026) studied this question.
