To explore the surgical technique and clinical effect of laparoscopic T tube+ double biliary catheter bundling and supporting drainage (LCTBS) of transabdominal consequent propulsive guidance technology for the treatment of extrahepatic bile duct stones with obstruction and stenosis of papillory during the course of therapeutic laparoscopy.

Clinical data of 45 patients who met the inclusion criteria between April 2001 and June 2018 were retrospectively analyzed.

It was in 45 cases removed the gallbladder and exploration of common bile duct by laparoscopy. Step by step dilatable catheter expanded duodenal papilla and indwelling T tube and double biliary catheter drainage was in 86.7% (39/45); step by step dilatable catheter combining balloon catheter expanded duodenal papilla and indwelling T tube and double biliary catheter drainage was in 4.4% (2/45); with duodenoscopic papillary sphincterotomy and indwelling T tube and double biliary catheter drainage due to residual stenosis of duodenal papilla was used in 6.7% (3/45); with indwelling T shape tube drainage due to place the double biliary catheter drainage result in failure was used in 2.2% (1/45). Residual stone was not occurred. Bile leakage was cured in one case (2.2%). There were no failed cases through the T tube fistula pull T tube and double biliary catheter support drainage. No cases had perforation of intestine and bile duct, bleeding, acute pancreatitis. No death. Total postoperative complication formation rate was in 2.2%(1/45).

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