Abstract:

Objective To investigate the effect of three-scope combined with transabdominal nasobiliary drainage in the treatment of extrahepatic bile duct stones. Method 80 patients with choledocholithiasis admitted to the Second People's Hospital of Xinhui District of Jiangmen City from March 2021 to August 2022 were retrospective analysis and randomly divided into observation group and control group with 40 cases each. Both groups of patients underwent laparoscopic cholecystectomy, bile duct exploration, transabdominal nasobiliary duct drainage, and primary suture. The observation group underwent antegrade placement of nasobiliary duct through the abdomen, and the control group underwent oral placement of nasobiliary duct drainage. The general

information, preoperative bilirubin, diameter of common bile duct, number of common bile duct stones, and other systemic diseases were compared between the two groups. The operation time, intraoperative blood loss, whether duodenal papillectomy was needed, catheterization time, catheterization success rate, postoperative intestinal recovery and exhaust time, abdominal drainage tube removal time, nasobiliary tube removal time, hospital stay and complications were compared between the two groups, and statistical analysis was performed. Result The operation time of patients in the observation group was longer than that in the control group, and the incision rate of duodenal papilla was significantly lower than that in the control group (P ＜ 0.05), there was no significant difference in intraoperative bleeding between the two groups (P ＞ 0.05). The intubation time, gastrointestinal recovery time, extraction time of abdominal drainage tube and nasobiliary duct in the observation group were shorter than those in the control group (P ＜ 0.05), however, there was no significant difference between the two groups in the success rate of intubation and the length of stay (P ＞ 0.05). The incidence of complications in the observation group was

significantly lower than that in the control group (P ＜ 0.05). Conclusion The application of three-scope combined with transabdominal nasobiliary drainage in the treatment of extrahepatic bile duct stones is effective and high security.
