Through a critical review of the literature, the authors analyze and re-assess the current diagnostic and therapeutic algorithms used in the treatment of mild acute biliary pancreatitis, reporting their experience with 27 cases observed in the Policlinico Umberto I Emergency Department (Rome) over the period from March 2003 to May 2005. All patients were treated with the same diagnostic and therapeutic protocol: once the diagnosis of acute biliary pancreatitis had been made and the severity evaluated, patients presenting clinical or ultrasonographic signs of main biliary duct stones underwent ERCP within 72 hours of onset of symptoms. All patients then underwent a standard-technique laparoscopic cholecystectomy during the same hospital stay, and whenever ERCP had not been performed preoperatively, an intraoperative cholangiography was performed at the time of surgery. No intra- or postoperative complications were observed, with a mean hospital stay of 10.6 days (range: 5-25 days).
