Laparoscopic cholecystectomy in acute mild gallstone pancreatitis: how early is safe?

Abstract

The surgical strategy to resolve the underlying biliary pathology in patients with acute gallstone pancreatitis (AGP) remains controversial. The aim of this study was to evaluate the safety and effectiveness of early laparoscopic cholecystectomy (ELC) in patients with mild AGP. A retrospective cohort of consecutive patients diagnosed with mild AGP according to the Atlanta Guidelines from January 2009 to July 2019 was selected. Patients were assigned to surgery on the first available surgical shift, 48h after the symptoms onset. Univariate analysis was performed to determine the association between AGP and grades of Balthazar (A, B and C) with time to surgery, days of hospitalization and postoperative complications. From 239 patients evaluated, 238 (99.58%) were operated by laparoscopic approach. Intraoperative cholangiogram was performed routinely. Choledocholithiasis, if present, was successfully treated by laparoscopic common bile duct exploration in all cases. A significant association was found between Balthazar grades and time to surgery (median of 3days, p = 0.003), with length hospitalization and from surgery to discharge, with median of 4days (p = 0.0001) and 2days (p = 0.003), respectively. Mild postoperative complications (CD I/II) were observed in 22/239 patients (9.2%). This represents 2% of patients with grade A of Balthazar, 9% of grade B and 14% of grade C (p = 0.016). We observed no severe complications or mortality. ELC with routine intraoperative cholangiogram, performed on the first available surgical shift 48h after the symptoms of pancreatitis onset, is a viable, effective and safe strategy for the resolution of mild AGP and its underlying biliary pathology in a single procedure.
