Early Versus Delayed Laparoscopic Cholecystectomy for Acute Cholecystitis with Mild Pancreatitis.

Abstract

The safety and feasibility of early laparoscopic cholecystectomy (LC) for acute cholecystitis with mild pancreatitis were explored. A total of 973 patients with acute pancreatitis, including 651 mild cases and 322 moderate or severe cases were retrospectively studied from July 2014 to December 2018 in our department. And 426 mild pancreatitis cases with acute cholecystitis were enrolled in this study, of which 328 patients underwent LC during the same-admission (early LC group), and 98 patients underwent LC a period of time after conservative treatment (delayed LC group). Clinical characteristics, operative findings and complications were recorded and followed up. The two groups were comparable in age, gender, the grade of American Society of Anesthesiologist (ASA), biochemical findings and Balthazar computer tomography (CT) rating (P>0.05). The operation interval and hospital stay in early LC group were significantly shorter than in delayed LC group (5.83±1.62 vs. 41.36±8.44 days; 11.38±2.43 vs. 16.49±3.48 days, P<0.01). There was no significant difference in the average operation time between the two groups. No preoperative biliary related events recurred in early LC group but there were 21 cases of preoperative biliary related events in delayed LC group (P<0.01). There was no significant difference in conversion rate (3.85 vs. 5.10%, P=0.41) and surgical complication rate (3.95 vs. 4.08%, P=0.95) between early LC group and delayed LC group. During the postoperative follow-up period of 375 cases, biliary related events recurred in 4 cases in early LC group and 3 cases in delayed LC group (P=0.37). The effect of early LC during the same-admission is better than delayed LC for acute cholecystitis with mild pancreatitis.
