title: Must ERCP Be routinely performed if choledocholithiasis is suspected?
abstract: OBJECTIVE
  To evaluate the results of preoperative endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment of those patients suspected of harboring bile duct stones before laparoscopic cholecystectomy (LC).
  
  
  METHODS
  A total of 1,235 consecutive LCs performed between 1991 and 1997 were studied prospectively. ERCP was performed to explore the common bile duct (CBD) preoperatively when choledocholithiasis was suspected on the basis of clinical, analytical or echographical data.
  
  
  RESULTS
  ERCPs were performed in 268 patients: unsuccessful CBD evaluation in 3%; dilated CBD without lithiasis in 13%, and normal exploration in 37% (99 patients). CBD stones were found in 46% (124 patients), and endoscopic sphincterotomy was then performed and stone extraction attempted. Endoscopic therapy achieved 92.8% successful removal of CBD stones (115 patients). There was no ERCP-related mortality and the morbidity rate was 6%. Retained CBD stones have been observed in 7 cases after ERCP-LC; all of them have been successfully treated by ERCP.
  
  
  CONCLUSIONS
  A combined approach to bile duct stones with selective use of ERCP followed by LC is a good therapeutical alternative. Nevertheless, the usual selection criteria for ERCP may lead to unnecessary exploration. It appears to be necessary to modify the current diagnostic and therapeutic strategy.
