Abstract

Twenty patients with symptomatic cholelithiasis and suspected choledocholithiasis were evaluated in an ongoing prospective trial using endoscopic ultrasonography (EUS), standard abdominal ultrasonography (US) and ERCP for the detection of choledocholithiasis prior to laparoscopic cholecystectomy. EUS was used successfully to image the extrahepatic bile duct in all patients. EUS detected three of four proven bile duct stones and correctly identified 16 bile ducts as stone free, thus being more accurate than standard abdominal US. The preliminary results of this ongoing prospective trial and the experience reported by other authors suggest that EUS may be as sensitive as ERCP in the detection of choledocholithiasis.
