|
Background/Aims: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosis and treatment of common bile duct stones (CBDS). However it is associated with some complications. Endoscopic ultrasonography (EUS) is an efficient diagnostic tool for CBDS with better accuracy than ultrasonography (USG) or computed tomography (CT) and lower complication rate than ERCP. We evaluated the diagnostic usefulness of EUS in suspicious CBDS. Methods: From Oct. 2001 to Mar. 2004, 84 patients with the suspicion of CBDS, without definite evidence on CT and/or USG were evaluated with EUS. The reports were reviewed retrospectively. Results: Patients were 38 males, 46 females with mean age of 56 years old. CBDS were found in 25 (29.8%) patients. In the diagnosis of CBDS undetected in CT and/or USG, EUS gave 96% sensitivity, 96.6% specificity, 92.3% positive predictive value and 98.3% negative predictive value. When CBDS were found in EUS, the average sizes of CBD and CBDS were 8.8 mm (4∼16.7) and 6.4 mm (3.3∼9.1) respectively. Diagnostic ERCP was avoided in 54 (64.3%). EUS provided additional diagnosis such as gallbladder stones, gallbladder cancer, ampullary cancer and adenoma. No complication was associated with EUS. Conclusions: EUS is reasonably safe and accurate procedure in detecting CBDS. EUS may possibly replace diagnostic ERCP in CBDS. (Korean J Gastrointest Endosc 2005;30:249256) |
