Abstract:Objective To compare the clinical efficacy of biliary stents and nasobiliary drainage in primary suture after laparoscopic common bile duct exploration (LCBDE).Methods We retrospective analyzed 74 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) stone removal failure from August 2016 to January 2021, then divided them into stent drainage group (n = 38) and nasobiliary duct drainage group (n = 36). After ERCP stone removal failure in the stent drainage group, biliary stent drainage was placed, while nasobiliary duct drainage was placed after ERCP stone removal failure in the nasobiliary duct drainage group. All these patients underwent laparoscopic choledocholithotomy and primary suture. The operation time, postoperative hospital stay, postoperative complication rate, postoperative intestinal function recovery time, postoperative choledocholithiasis recurrence rate and total hospital stay were compared between the two groups.Results There was no significant difference between the two groups in bile duct suture mode, operation time, intraoperative bleeding, incidence of total postoperative complications and hospitalization expenses (P > 0.05). The incidence of postoperative biliary fistula in the nasobiliary duct drainage group was significantly lower than that in the stent drainage group, and the hospital stay was significantly shorter than that in the stent drainage group, the postoperative intestinal function recovery time was significantly longer than that in the stent drainage group, and the total postoperative fluid replacement volume was more than that in the stent drainage group, with statistical significances (P < 0.05).Conclusion Placing nasobiliary drainage after ERCP stone removal failure can reduce the incidence of biliary fistula after primary suture after LCBDE and reduce the length of hospital stay. However, patients with biliary stents have faster recovery of intestinal function and less fluid replacement. Therefore, the corresponding individualized drainage mode should be selected according to the specific situation of patients in clinical operation.
