Abstract: Objective To investigate the diagnostic significance of endoscopic ultrasonography (EUS) for suspected choledocholithiasis in non-cholangiectasis. Methods EUS was performed on 33 patients with cholecystolithiasis, whose common bile duct diameters were less than 8 mm, with one of the histories of acute pancreatitis, obstructive jaundice or recurrent biliary colic, but without common bile duct stone (CBDS). The results were compared with surgical or ERCP findings. Results Twenty cases in 33 were diagnosed ascholedocholithiasis by EUS. Sixteen of the 20 cases were confirmed as CBDS with further operation or ERCP. Compared with the results of surgery or ERCP, the sensitivity, specificity, positive prediction value and negative prediction value of EUS for choledocholithiasis were 100% , 76. 5% , 80% and 100% respectively. Conclusion EUS is of high diagnostic significance for suspected choledocholithiasis in non-cholangiectasis.
