Abstract

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) is currently the best approach for complex cases of choledocholithiasis or the cases of endoscopic retrograde cholangiopancreatography (ERCP) failure. Nevertheless, there is no clear consensus on the optimal duct closure method after LCBDE. The purpose of this study was to evaluate the efficacy of 3 duct closure methods after LCBDE for choledocholithiasis.

MATERIAL AND METHODS: In this analysis, 189 patients with choledocholithiasis underwent LCBDE between June 2014 and December 2018. According to different duct closure methods, these patients were divided into T-tube drainage (TTD) group (n=66), common suture group (n=64) and barbed suture group (n=59). The operation time, suturing time, amount of intraoperative bleeding, tube-carried time, length of stay (LOS), hospitalization costs, pre- and post-operative common bile duct (CBD) diameters were all compared among the 3 groups. Six months after discharge, the incidence of complications and recurrent stones was observed.

RESULTS: The operation time, suturing time, and amount of intraoperative bleeding in barbed suture group were both significantly less than those in the common suture group and the TTD group (P<0.01). When compared with the TTD group, the suturing time, tube-carried time, and LOS were decreased markedly in the common suture group and the barbed suture group (P<0.01). The post-operative CBD diameters in the 3 groups were all significantly larger than the pre-operative CBD diameters (P<0.01). There was no statistical significance among the 3 groups regarding the incidence of complications and recurrent stones (P>0.05).

CONCLUSIONS: Barbed suture shortened the suturing time, operation time, tube-carried time, and LOS, and lessened the amount of intraoperative bleeding in patients with choledocholithiasis after LCBDE. It was more effective than the common suture and TTD.
