ABSTRACT
Objective To explore the application value of nasobiliary duct instead of T-tube in primary suture after laparoscopic common bile duct exploration (LCBDE). Methods A total of 58 cases of choledocholithiasis without acutecholangitis were divided into experimental and control group according to the odevity of the last number of admission number .Patients in odd number belonged to experimental group , while the even number patients belonged to control group .The experimental group received endoscopic nasobiliary drainage ( ENBD ) combined with LCBDE and primary suture;the control group underwent LCBDE combined with T-tube drainage .The intraoperative and postoperative data were compared between the two groups . Results All surgeries were completed successfully under laparoscope .The experimental group had much shorter hospital stay than that of the control group [(7.5 ±2.1) d vs.(10.3 ±3.2) d,t=-3.965,P=0.000].No significant differences were found in the operative time , incidence of bile leakage and postoperative incision pain between the two groups (P>0.05).All the cases were followed up for 6-12 months (average, 9 months) and no patients were hospitalized due to complications related to the billiary surgery .MRCP showed no complications such as biliary stricture and residual stones 6 months after operation . Conclusions Nasobiliary duct can substitute for T-tube in LCBDE .It ensures the safety of the primary suture and reduces T-tube related complications .
