Clinical application of backtracking full-thickness continuous everting suturing in primary closure of common bile duct after laparoscopic bile duct exploration / 中华肝胆外科杂志

ABSTRACT

Objective:To analyze the results in clinical application of backtracking full-thickness continuous everting suturing in primary closure of common bile duct after laparoscopic bile duct exploration.Methods:From February 2014 to November 2018 at the Affiliated Changzhou No.2 People’s Hospital of Nanjing Medical University, 82 patients with cholecystolithiasis and choledocholithiasis entered into this study. There were 45 males and 37 females, with an average age of 62.7 years. These patients underwent primary closure of common bile duct after laparoscopic bile duct exploration using backtracking full-thickness continuous everting suturing to close the incisions in common bile ducts. Clinical data on surgery, postoperative complications and follow-up were collected and analyzed retrospectively.Results:Primary closure of common bile duct was successfully carried out in all patients. The operation time ranged from 45 to 150 min (average 68.5 min). Intraoperative blood loss ranged from 5 to 150ml (average 18.4 ml). Postoperative bile leakage occurred in 2 patients (2.4%). There were no intra-abdominal or biliary bleeding, severe cholangitis, liver function derangement, abdominal infection or residual stones. Of 77 patients who were followed up (follow-up rate of 93.9%), the follow-up time ranged from 9 to 50 months (median 14 months). On follow-up, 2 patients (2.4%) developed recurrence of choledocholithiasis and 1 patient (1.2%) was diagnosed to have intrahepatic bile duct stones. There were no patients with bile duct stenosis or acute cholangitis.Conclusion:Primary closure of common bile duct with backtracking full-thickness continuous everting suturing has the advantage of reducing postoperative bile leakage in patients after laparoscopic bile duct exploration. The long-term effects of this technique still need further clinical studies.
