Anatomical identification of the bile duct by intrinsic illumination in difficult cholecystectomies: Prometheus device

Bile duct injury remains one of the most feared complications after cholecystectomy.The Prometheus device, through intrinsic illumination, facilitates intraoperative anatomical identification of biliary structures.In a case of cholecystitis, it was used during a conventional cholecystectomy, advancing it through Hartmann's pouch to the confluence with the common hepatic duct, illuminating the biliary structures and enhancing critical view of safety.This device proved to be a safe and accessible method, with potential for use in most healthcare centers.
