Objective This study aims to investigate the clinical efficacy of laparoscopic cholecystectomy（LC）combined with endoscopic retrograde cholangiopancreatography（ERCP）or endoscopic sphincterotomy（EST）in the treatment of gallbladder stones complicated by extrahepatic bile duct stones．Methods A total of 86 patients with gallbladder stones and extrahepatic bile duct stones treated at the First Hospital of Nanping from January 2020 to June 2023 were selected．According to different treatment regimens,they were divided into a control group（n=40）and an observation group（n=46）．The control group received LC combined with laparoscopic common bile duct exploration（LCBDE）,while the observation group received LC combined with ERCP and EST．Surgical-related indicators,angiotensin levels,liver function,and complications were observed in both groups．Results The observation group had less intraoperative bleeding than the control group（t=12.440,P<0.001）．The observation group had a shorter operation time,postoperative anal exhaust time,and hospital stay than the control group（all P<0.001）．The levels of angiotensin 1-7（Ang1-7）,angiotensin I（AngⅠ）,and angiotensin II（AngⅡ）in the observation group were lower than those in the control group,with no statistically significant differences between the groups（all P>0.05）．Total bilirubin（TBIL）and alanine aminotransferase（ALT）levels in the observation group were comparable to those in the control group（all P>0.05）．No patients in the observation group experienced bile leakage or residual stones,while the incidence rates in the control group were 5.00% and 2.50%,respectively,with no statistically significant differences between the groups（all P>0.05）．The observation group had lower rates of bleeding and biliary tract infection at 4.35% and 2.17%,respectively,compared to the control group at 10.00% and 5.00%,with no statistically significant differences between the groups（all P>0.05）．Conclusions LC combined with ERCP/EST in the treatment of gallbladder stones complicated by extrahepatic bile duct stones can reduce intraoperative bleeding,shorten operation time,and decrease hospital stay．
