Evolving management of mild-to-moderate gallstone pancreatitis

Abstract

The objective of this study was to describe recent trends in the management of mild-to-moderate gallstone pancreatitis and assess patient outcomes. Acute gallstone pancreatitis has traditionally been managed with open cholecystectomy and intraoperative cholangiography during the initial hospitalization. The popularization of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy has made a reassessment necessary. Two consecutive time periods were retrospectively analyzed: prior to laparoscopic cholecystectomy (prelaparoscopic era [PLE]) and after the diffusion of laparoscopic cholecystectomy (laparoscopic cholectomy era [LCE]). There were 35 patients in the PLE group and 58 in the LCE group. LCE patients waited 37.1 +/- 63 days from admission until cholecystectomy, compared to 9.8 +/- 14.8 days in the PLE group (P = 0.04). Biliary-pancreatic complications occurred in 24% of LCE patients and only 6% of PLE patients (P = 0.05), nearly always while they were awaiting cholecystectomy (P = 0.009). Patients in either time period who underwent cholecystectomy with intraoperative cholangiography developed less pancreatic-biliary complications than those who underwent ERCP prior to cholecystectomy, with or without sphincterotomy. Delaying the interval from pancreatitis to laparoscopic cholecystectomy beyond historical values is associated with a greater risk of recurrent biliary-pancreatic complications, which are not prevented by the use of ERCP. Early cholecys tectomy with intraoperative ductal evaluation is still the approach of choice.
