Cholecystectomy is the treatment of choice for gall bladder stone since centuries. Bileduct injuries are associated with cholecystectomy since beginning. In last three decades gall bladder removal by laparoscopy has superseded the open method but the incidence of bile duct injuries remained same especially with beginners. This is mainly dueto misinterpretation of anatomy at calot’s triangle. The meticulous surgery for the gall bladder during cholecystectomy has prime role in prevention of bile ductinjury. We have recently use real time identification of bile duct during surgery by infra red method. This infra red technology has come in the way with more than 99% sensitivity in bile ducts identification. Indocyanine Green(ICG) is a florescent dye which is used for this purpose. Dye injected before operation is detected by a special telescope mounted on a high definition camera. This telescope emits infra red which detects ICG dye inside bile ducts. This helps in detection of biliary anatomy and prevents bile duct injuries.
