Objective: To explore the indications and the value ofendoscopic retrograde cholangiopancreatography(ERCP)in perioperative phase of laparoscopic cholecystecto-my.Methods: From January 1998 to April 1999, a total of1500 consecutive laparoscopic cholecystectomies wereanalyzed. The indications for preoperative group (n=33) included elevated bilirubin level and alkalinephosphatase level, jaundice, pancreatitis, abnormalliver function, dilated bile duct and/or stones on ul-trasound or CT. The indications for postoperativegroup (n=20) included clinical signs or symptoms aswell as common bile duct stones demonstrated by in-traoperative cholangiography.Results: Preoperative ERCP for 32 patients (2.1%)showed abnormalities in 12 (37%). Postoperative ER-CP for 20 patients(1.3%) demonstrated abnormalitiesin 14 (70%). Super-selected criteria for preoperativeERCP would predict more than 66% ductal stones.Endoscopic sphincterectomy and duct stones clearancewere performed in all 16 patients with documentedcommon bile duct stones. The morbidity was confinedin 2 patients with self-limited pancreatitis (3%).Conclusions: Using super-selected creteria to selectpatients for preoperative ERCP can avoid unnecessaryERCP. As soon as postoperative patients have clinicalsigns or symptoms, endoscopic treatment should beperformed.
