To explore the surgical technique and clinical effect of laparoscopy, choledochoscopy, dilatable catheter, T tube and plastic biliary stent bundling drainage (LCDTS) for the treatment of extrahepatic bile duct stones with obstruction of papillory.

The clinical data of 52 cases of extrahepatic bile duct stones with obstruction of papillory undergoing LCDTS were analyzed retrospectively from November 1999 to September 2017 in the Second People’s Hospital of Chengdu.

52 cases were preformed laparoscopic cholecystectomy and exploration of common bile duct. The duodenal papilla was expanded step by step with dilatable catheter , T tube and plastic biliary stent drainage was indwelled in 39 cases (39/52); The duodenal papilla was expanded step by step with dilatable catheter and balloon catheter, and T tube and plastic biliary stent drainage was indwelled in 6 cases (6/52); duodenoscopic papillary sphincterotomy and indwelling T tube and plastic biliary stent drainage was performed due to failure of step by step expanding. in 5 cases (5/52); T shape tube drainage was performed due to failure of placing the plastic biliary stent drainage in 2 cases (2/52). Residual stone was found in 1 case (1/59), bile leakage was found in 1 case (1/59), 2 cases (3.8%) were unsuccessful to pull out the stent through the T tube fistula. No cases was found with perforation of intestine and bile duct, bleeding, acute pancreatitis. No death cases was found. The total postoperative complication rate was 7.7%(4/52).

From preliminary results of limited cases in this study from our hospital, if patients are suitable, LCDTS for treatment of the extrahepatic bile duct stones with obstruction of papillory is safe and effective.
