title: The role of endoscopic retrograde cholangio-pancreaticrogram in laparoscopic cholecystectomy.
abstract: Four hundred and fifty-nine patients were studied to evaluate the role of diagnostic and therapeutic endoscopic retrograde cholangio-pancreaticrogram (ERCP) in their management before laparoscopic cholecystectomy (LC) when choledocholithiasis is suspected. Using bilirubin, liver function tests (LFTs) (alkaline phosphatase, SGOT, SGPT) and findings on ultrasound of a dilated common bile duct (CBD), 37 patients (8.1%) were suspected of having concomitant common bile duct stones preoperatively. These patients were subjected to the following diagnostic and therapeutic procedures: 25 ERCPs, 20 laparoscopic cholangiograms, and three extracorporeal shock wave lithotripsies. Preoperative ERCP was done on 19 patients, intraoperative ERCP-sphincterotomy was done on one patient, and postoperative ERCP-sphincterotomy was done on five patients. Fifteen laparoscopic cholangiograms were done as primary tests and five after preoperative ERCP. Sixteen patients (3.5%) had stones in their CBD. Four patients had their laparoscopic cholecystectomy cancelled, and one patient had laparoscopic common duct exploration that was converted to an open procedure. Three groups were identified: group I, patients with a high index of suspicion, included elevated bilirubin with elevation of all three LFTs, or normal bilirubin with elevation of all three LFTs with or without dilated CBD. Seventy-five per cent of this group had CBD stones. Group II, patients with a low index of suspicion, included normal bilirubin and normal CBD by ultrasound with elevation of the alkaline phosphatase alone or elevation of two of the three LFTs. Six per cent of this group had CBD stones. Group III, patients with no index of suspicion, were patients with normal preoperative laboratory test results and CBD. Two patients (0.47%) in this group had elevated LFTs postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)
