Operation was performed successfully in both groups. In the experimental group, the common hepatic duct, common bile duct and gallbladder duct were developed successfully in all patients, 54 cases and 52 cases respectively, and the developing time of the three tubes was (15.8±1.2) min. In the experimental group, the time of three tubes, operation time, intraoperative blood loss and abdominal drainage tube placement were (18.5±1.3) min, (64.0±6.8) min, (16.3±6.7) mL, 43 cases, respectively. In the control group, there were (46.3±8.1) min, (98.7±10.5) min, (53.6±14.9) mL and 55 cases, respectively. The experimental group was significantly lower than the control group, and the difference between the two groups was statistically significant ( P< 0.05). There was no case of conversion to laparotomy and bile ductinjury in the experimental group, and 1 case of conversion to laparotomy and 1 case of bile ductinjury in the control group, and there was no statistical significance between the two groups ( P>0.05). There were significant differences in postoperative extubation time and postoperative hospital stay between the two groups ( P<0.05). ALT and GGT levels were 47(31, 75) U/L and 38(19, 114) U/L in the experimental group and 62(53, 92) U/L and 76(63, 96) U/L in the control group at the first postoperative review, with statistically significant differences between the two groups ( P<0.05). Patients in both groups were followed up for 3 months after discharge. There were no obvious complications in the experimental group, and 1 case had a small amount of peritoneal effusion 7 days after discharge in the control group.
