Interval Laparoscopic Cholecystectomy in the Management of Acute Biliary Pancreatitis

The timing of laparoscopic cholecystectomy following an attack of acute biliary pancreatitis is controversial. The traditional approach of interval cholecystectomy has been challenged recently. The present study was designed to evaluate the benefits of interval laparoscopic cholecystectomy for patients with mild acute pancreatitis (Ranson less than 3). Nineteen patients with mild pancreatitis underwent ultrasonographic evaluation to confirm the biliary etiology. ERCP was performed in all patients on the first available endoscopy list, and endoscopic sphincterotomy was performed in two patients with calculi or dilated common bile duct on ultrasonographic examination. Medical treatment was administered and laparoscopic cholecystectomy was scheduled after 8–12 weeks to allow the inflammatory process to settle. There were no recurrent attacks of pancreatitis during this period. The degree of difficulty of the laparoscopic procedure was assessed by the presence of adhesions to the gallbladder area, difficulty of dissection in the Calot's triangle, intraoperative bleeding and the need for a drain. Six patients (31.5%) had severe adhesions, difficult dissection of the cystic duct and artery, bleeding and prolonged operating time. In two of these patients (10.5%) the procedure was converted to open cholecystectomy. In conclusion, our results suggest that postponing laparoscopic cholecystectomy in acute pancreatitis patients is not advantageous surgically and does not justify the risk of further morbidity caused by the gallbladder disease.
