Common bile duct stones in clinical manifestations of biliary colic, obstructive jaundice, cholangitis, pancreatitis and other symptoms. At present, thanks to the rapid development of minimally invasive surgery and the concept of ERAS, laparoscopic common bile duct incision and primary suture has been gradually used as a routine surgical approach in clinical application. However, whether or not to place the abdominal drainage tube after surgery, so far has not yet reached a consensus. Therefore, this study focuses on the clinical advantages of LCBDE+PC placed abdominal drainage.

On the basis of the analysis of 7 cases were selected by laparoscopic treatment of cholecystolithiasis complicated with choledocholithiasis bile duct suture in patients with a clinical data of our hospital were prospectively divided into peritoneal drainage group of 40 cases, no abdominal drainage group of 40 cases, compared two groups of operation time, hospitalization time and cost, operation cost, operation bleeding and postoperative bilirubin recovery, complication and return to hospital again and so on, and to explore the clinical significance of indwelling drainage tube.

  • the presence of severe cholangitis requiring emergency biliary drainage;
  • it is difficult to get a combination of intrahepatic bile duct stones and choledochoscopy;
