Abstract
OBJECTIVE: Primary closure of the common bile duct (CBD) after laparoscopic CBD exploration (LCBDE) is a technical challenge. The present study was performed to evaluate the safety and effectiveness of this surgical method. METHODS: This retrospective study of surgical efficacy and safety involved 79 patients who underwent primary CBD closure with a knotless unidirectional barbed suture or traditional T-tube drainage after LCBDE for CBD stones. RESULTS: The average suturing time, operation time, and postoperative hospital stay were significantly shorter in the primary closure group than T-tube group. There were no significant differences in the mean diameter of the CBD, number of stones, or incidence of postoperative complications between the two groups. No patients developed recurrence of CBD stones during the median follow-up of 21.5 months. CONCLUSIONS: After LCBDE and intraoperative choledochoscopy, primary closure with knotless unidirectional barbed sutures is a safe and effective therapeutic option for patients with cholelithiasis and concurrent CBD stones. This is especially true when the CBD is dilated more than 8 mm.
