Abstract:Objective To discuss the clinical skill of tubal catheter combined with laparoscopy in treatment of choledocholithiasis.Methods Retrospective analysis was performed using clinical data of 48 patients with choledocholithiasis were treated by tubal catheter combined with laparoscopic common bile duct exploration from Febrary 2017 to January 2018.Results All these patients were successfully removed and all common bile duct stones were removed under laparoscopy, 43 cases accepted primary suture and 5 cases accepted T tube drainage. The operation time was 45~180 min with the average operation of 116 min, the postoperative hospital stay was 6~14 d with the average of 8 d. Postoperative biliary leakage occurred in 1 cases, were treated conservatively and cured in 9 d. No postoperative residual calculi was confirmed by T-tube cholangiography in 4~6 weeks after surgery in 5 cases accepted T tube drainage, then the T tube was removed. All the patients were followed for three months to 1 year, and the residual stones and biliary stricture were not found.Conclusion Tubal catheter combined with laparoscopy in the treatment of choledocholithiasis is a safe, feasible and effective method. Master the methed how to use the tubal catheter to flush and remove the choledocholithiasis, rich experience in laparoscopy and careful operation are the key to successful operation.
