Abstract:
Objective To investigate the application of intraoperative indocyanine green (ICG) cholangiography in the accurate identification of the common bile duct since common bile duct injury is a common complication of laparoscopic cholecystectomy (LC), and to reduce the incidence rate of common bile duct injury during LC. Methods A total of 68 patients who underwent LC in Zhuhai People's Hospital from April 2021 to Jane 2021 were enrolled, among whom 56 patients underwent conventional LC and 12 patients underwent LC under the guidance of ICG cholangiography. The common bile duct, cystic duct, and gallbladder were examined by white light laparoscopy for the conventional LC group and near-infrared laparoscopy for the ICG cholangiography group. The propensity score matching method was used to balance the preoperative data between the two groups. The t -test and the chi-square test were used for comparison of intraoperative blood loss, time of operation, length of postoperative hospital stay, and incidence rate of common bile duct injury between the two groups. Results Compared with the conventional LC group, the ICG cholangiography group had significantly lower intraoperative blood loss 3.1±0.9 mL vs 10.8±2.3 mL, t =-22.709, P < 0.05), significantly shorter time of operation (20.2±1.6 min vs 48.3±5.1 min, t =-19.856, P < 0.05) and length of postoperative hospital stay (1.2±0.3 days vs 2.3±0.8 days, t =-19.507, P < 0.05), and a significantly lower incidence rate of complications (0 vs 8.3%, χ 2 =1.287, P < 0.05). Conclusion ICG cholangiography is an effective method to differentiate between the common bile duct and the cystic duct during LC and can prevent common bile duct injury. This method has great advantages in the treatment of patients with gallstones due to its high degree of identification of the biliary tract, long onset time, repeated application, convenient operation, and ability to be combined with intraoperative navigation device.
