Objective:To juxtapose laparoscopic cholecystectomy combined with common bile duct exploration and stone extraction (LC+ LCBDE) against endoscopic retrograde cholangiopancreatography/sphincterotomy with laparoscopic cholecystectomy (LC+ ERCP/EST) in the therapeutic context of acute biliary pancreatitis.Methods:The clinical data of patients with acute biliary pancreatitis in Department of Hepatobiliary Surgery, Datong Third People's Hospital from January 2017 to January 2021 were retrospectively analyzed. A total of 44 patients were inrolled, including 23 males and 21 females, with the age of (60.6±11.7) years. Based on different treatment approaches, the patients were divided into the LC+ LCBDE group ( n=33) and the LC+ ERCP group ( n=11, LC+ ERCP/EST). Total bilirubin, direct bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood amylase, operation time, postoperative hospitalization stays, total hospitalization cost, postoperative anal exhaust time, and postoperative complications (bile leakage, fever, bleeding) were compared between the two groups. Results:There were no significant differences in preoperative total bilirubin, direct bilirubin, ALT, AST, and blood amylase between LC+ ERCP group and LC+ LCBDE groups (all P>0.05). In LC+ LCBDE group, operation time was 110.0 (96.3, 147.5) min, postoperative hospitalization time was 9.0 (7.5, 11.0) d, postoperative exhaust time was 2.0 (1.0, 2.0) d, and in LC+ LCBDE group, operation time was 60.0 (32.0, 65.0) min, postoperative hospitalization time was 7.0 (4.0, 8.0) d, postoperative exhaust time was 1.0 (1.0, 1.0) d. Comparisons with LC+ LCBDE group, LC+ ERCP group had shorter postoperative hospitalization stay and earlier postoperative exhaust time, the total hospitalization cost of LC+ LCBDE group was 23 829.3 (21 779.6, 27 221.9) yuan, which was higher than 36 894.8 (31 963.5, 41 172.2) yuan in LC+ ERCP group, and the differences were statistically significant (all P<0.05). Comparison of postoperative total bilirubin, direct bilirubin, ALT and AST between LC+ ERCP group and LC+ LCBDE group, with no significant difference(all P>0.05). No postoperative complications such as bile leakage, residual stones, fever and bleeding occurred in both groups. Conclusion:Compared with LC+ ERCP/EST, LC+ LCBDE in the treatment of acute biliary pancreatitis, although the operation time and hospital stay are longer, but the total hospitalization cost is less, there is no need for multiple operations, and it can be used as the first choice for acute biliary pancreatitis.
