Objective:To research the clinical value of preoperative insertion of nasobiliary tube for after laparoscopic〖JP〗 exploration of common bile duct (CBD) and replacement of Ttube drainage with primary suture of (BD).
Methods:A retrospective analysis of clinical data of 102 cases of laparoscopic common bile duct exploration due to choledocholithiasis. The clinical effects of 55 cases of preoperative insertion of nasobiliary tube and primary suture of common bile duct(Nasobiliary group) were compared with 47 cases of Ttube drainage(Ttube group).
Results:Both of the groups successfully completed operation without postoperative bile leakage. The extubation time of nasobiliary group was (5.3±1.8)d. The postoperative hospitalization (7.2±1.6)d, time to pass flatus（20.3±5.8）d, which were all shorter than those of Ttube group (29.6±6.3d, and 15.3±3.8, respectively), with significant differences. There were no significant differences in operation time and complications (P>0.05) betweent the 2 groups (P<0.01).
Conclusions:Preoperative insertion of nasobiliary tube and primary suture of common bile duct can prevent not only bile leakage caused by increased biliary pressure after primary suture, but also completely eliminates complications caused by Ttube,and can shortens hospital stay. It is worth widespresd application.
