ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY IN CONJUNCTION WITH LAPAROSCOPIC CHOLECYSTECTOMY

Laparoscopic cholecystectomy (LC) has become the primary surgical treatment for symptomatic cholelithiasis. In conjunction with the dramatic rise in LC there has been an increase in the number of endoscopic retrograde cholangiopancreatographies (ERCPs) performed. For this study, the records of patients referred to the surgical endoscopy department between January 1991 and February 1992 were reviewed. Seventy-seven ERCPs were performed in conjunction with LC. The indications for ERCP included jaundice or a history of jaundice, gallstone pancreatitis, a suspicious filling defect on either ultrasound or intraoperative cholangiogram, abnormal liver function tests, cholangitis, or postoperative bile leak. Sixty-two procedures were performed prior to LC and 15 procedures after LC. Forty-two patients were female (54.5%) and the patients ages ranged from 14 to 92 years (mean 54.1 years). Of the 62 patients having ERCP preoperatively 35 patients (56.5%) had no evidence of common bile duct (CBD) stones and underwent LC as planned. Twenty-three patients were found to have CBD stones, of which six were referred for an open cholecystectomy and CBD exploration, because of large multiple CBD stones or the presence of a large duodenal diverticulum. Seventeen patients had their CBD cleared endoscopically, and four patients were not successfully cannulated. Fifteen patients had ERCP after LC. There were two patients with CBD injuries who were referred for surgical correction. Two patients had leakage from the cystic duct stump, and four patients had CBD stones, all of whom were successfully treated with endoscopic sphincterotomy. There were four patients who had a normal postoperative ERCP and two patients who could not have their CBD cannulated. There were no mortalities, but there were four cases of complications. Two patients had bleeding after stone extractions, and they required blood transfusions. One patient developed cholangitis from stenosis of the papilla after an endoscopic sphincterotomy, and one patient developed pancreatitis which resolved with conservative treatment. There is an increasing role for ERCP and sphincterotomy in patients undergoing LC. ERCP carries an inherent morbidity and therefore routine ERCP is not justified. However, with the proper suspicion of CBD stones a preoperative ERCP is indicated prior to a planned laparoscopic cholecystectomy.
