The injury of common bile duct (CBD) is one of the most common complications during laparoscopic cholecystectomy. Consequences of CBD injury are grave since CBD is the only pathway of bile from biliary tracts to duodenum. When CBD injury occurs, extra surgical procedures repairing CBD or reconstructing biliary tracts have to be performed on patients, which increase expenses of patients and physical trauma. A total of 238 patients undergoing laparoscopic cholecystectomy (LC) in Zhuhai People’s Hospital from July 2020 to April 2021 were enrolled in this observational study, including 126 patients undergoing conventional LC and 112 patients undergoing ICG angiography-guided LC. Method of propensity score matching was used to balance the preoperative data of patients in the two groups. For both groups, the “Critical View of Safety” (CVS) was introduced. For the ICG group, the CBD, cystic duct (CD), and gallbladder were identified using near-infrared (NIR) ray. Intraoperative blood loss, operation time, postoperative hospitalization time, and the incidence rate of intraoperative complications were compared between the two groups. ICG angiography in LC shows safe and effective outcomes. The intraoperative blood loss, operation duration, postoperative hospitalization time, and complication incidence rate of the ICG group are significantly lower than those of the conventional group. ICG angiography in LC was a useful and effective method to identify the CBD and prevent intraoperative complications.
