Abstract
Objective: Evaluating the results of laparoscopic cholecystectomy (LC) using indocyanine green (ICG) fluorescence. Materials and methods: This is a cross-sectional study of patients with LC using real-time fluorescent ICG to treat gallbladder disease from May 2021 to May 2022 in the 108 Military Central Hospital. Results: There were 68 patients who underwent LC using intraoperative ICG fluorescence for bile duct visualization. The mean age of the patients was 55.4±16.2, and the male/female ratio was 1.52. Chronic cholecystitis caused by stones accounted for the majority (51.47%). The authors detected 7.35% of cases with anatomical changes of the extrahepatic biliary tract using ICG fluorescence and clearly identified the anatomy of the common bile duct and the cystic duct at 100 and 92.65%, respectively. The average surgical time was 42.8±14.6 min. There were no postoperative complications or side effects from ICG; the average hospital stay was 2.8±1.5 days. Conclusions: ICG fluorescence cholangiography allows surgeons to easily identify critical anatomical landmarks in the LC. Thereby helping the surgery to be performed safely, avoiding severe complications due to damage to the biliary tract.
