Integration of ICG-fluorescence cholangiography into the safety system of laparoscopic cholecystectomy

Abstract

Is evaluating the possibility of integrating ICG-fluorescent cholangiography into the general safety system for laparoscopic cholecystectomy to prevent damage to the extrahepatic bile ducts by working out the methodological aspects of navigation technologies. The analysis of literature data on various approaches to improve the perioperative identification of anatomical structures during laparoscopic cholecystectomy, including the ICG-fluorescent cholangiography, was carried out. This program was implemented during the provision of elective surgical care to 24 patients with cholelithiasis who underwent laparoscopic cholecystectomy with ICG-fluorescent navigation. The developed program included: preoperative assessment of the anatomy of the biliary tree using MRCP; intraoperative technique of safe laparoscopic cholecystectomy with mandatory application of the concept of «critical view of safety» (CVS), which allows the most effective identification of the necessary anatomical structures; the use of ICG-fluorescent cholangiography, which allows to improve the control of anatomical structures at all stages of the operations. The first experience of using ICG-fluorescent cholangiography testifies to the high informative value of the method, the possibility and prospects of integrating the technology into a comprehensive safety system during laparoscopic cholecystectomy.
