Clinical Study of Priority Exposure of Common Bile Duct in Laparoscopic Cholecystectomy to Prevent Biliary Tract Injury
Main Article Content
Abstract
The purpose of this study was to investigate the safety and feasibility of preferentially exposing the common bile duct in the prevention of iatrogenic biliary tract injury during laparoscopic cholecystectomy. The methods were retrospectively analyzed, and a total of 572 cases of LC were selected as the study group from March 2019 to December 2024. From March 2011 to December 2018, a total of 506 LC cases were used as control groups. The research group actively dissected the hepatoboduodenal ligament to reveal the common bile duct, clarified the location of the gallbladder duct into the common hepatic duct and then ligated and cut off the gallbladder duct, and the control group directly found and exposed the cystic duct and then ligated and cut off the gallbladder duct. The results showed that there was no intraoperative transmission of abdomen and biliary tract injury in the study group, no bile duct stenosis and 1 case of residual gallbladder after 6-36 months of follow-up. In the control group, there was 1 case of intraoperative laparotomy, 6 cases of biliary tract injury, 8 cases of bile duct stricture and 8 cases of residual gallbladder after 6-36 months of follow-up, and the difference was statistically significant (P<0.05). There were no significant differences in the type of gallbladder disease, preoperative comorbidities, operative time, intraoperative bleeding, and postoperative hospital stay between the study group and the control group. The conclusion is that LC has more advantages in preventing iatrogenic biliary tract injury, reducing surgery-related complications, and improving clinical prognosis.
