Objective To explore the timing of laparoscopic cholecystectomy for mild acute biliary pancreatitis.Methods The clinical data of 48 patients with mild acute biliary pancreatitis admitted to the Department of Hepatobiliary Surgery of Suzhou Mu-nicipal Hospital from July 2021 to June 2023 were retrospectively analyzed.They were divided into two groups:the early operation group(25 patients,LC was performed within 7 days after the onset)and the late operation group(23 patients,LC was performed 7 days after onset,before discharge),Observe the average hospitalization days,average hospitalization expenses,operation time,intraop-erative bleeding,conversion to laparotomy rate and postoperative complications of the two groups.Results All 48 patients successfully underwent laparoscopic cholecystectomy.The average length of stay in the early group was 12.44±1.65 days,the average cost was 18200±2 500 yuan,the average length of stay in the late group was 20.53±3.75 days,and the average cost was 26 400±4 500 yuan.The average length of stay and the average cost of stay in the early group were lower than those in the late group(P<0.05),which was statistically significantly.However,there was no statistically significant difference between the two groups in operation time,intr-aoperative bleeding,conversion rate of laparotomy and postoperative complications(P>0.05).Conclusion LC is safe and feasible treatment for early mild acute biliary pancreatitis,and it can significantly reduce the length of stay and hospitalization costs,which is worthy of clinical promotion.
