Abstract: Objective To investigate the feasibility of using endobiliary stent for primary suture after laparoscopic common bile duct exploration. Methods A total of 96 patients had laparoscopic common bile duct exploration between January 2016 and January 2018，47（49%），in whom underwent primary suture （primary suture group） and others （51%） received endobiliary stent implantation （endobiliary stent group）. Operative parameters and outcomes in the two groups were compared. Results The patients of two groups were cured to discharge from hospital. No mortality nor stones residue were found in two groups. First feeding time，drainage tube removal time，and postoperative stay were all significantly shorter in the endobiliary stent group as compared to that in the primary suture group （P<0.05）. Otherwise ， surgical time，intraoperative blood loss，bile leakage，and postoperative bleeding between the two groups had no significant difference （P>0.05）. Four patients suffered from bile leakage and recovered by short period drainage，and two patients with postoperative bleeding were cured after blood transfusion. The stent was removed by gastroscopy 2-3 weeks postoperatively ，while in some cases the stent was excreted spontaneously. The follow?up lasted for 1-6 months，and no stone recurrence or bile duct stenosis were found. Conclusion Using endobiliary stent for primary suture after laparoscopic common bile duct exploration is an effective and feasible method for common bile duct stone. It has better recovery and does not increase the incidence of biliary complications.
