Background and study aim. Endoscopic
ultrasound (EUS) is a diagnostic modality that continues
to expand its clinical applications. The aim of this study
is to evaluate the diagnostic role of EUS in common
bile duct stones. Patients and methods: This study was
carried on 29 patients with suspected CBD stones from
them only 15 patients were diagnosed as Common Bile
Duct stone(s). Endoscopic retrograde cholangiopancreatography
(ERCP) is considered as gold standard for
diagnosis of CBD stones and compare EUS findings
with that of ERCP. Results: The diagnostic performance
of EUS shows that the sensitivity, specificity, PPV, NPV
and accuracy of 100%, 92.8%, 93.7%, 100% and 96.5%
respectively. It can catch 15 true positive cases with
only one false positive case and 13 of 14 true negative
cases. EUS is considered as a minimally invasive
method with low incidence of complications, allowing
exact determination of the site and size of stones. So
EUS aid in better planning for CBD stone removal.
Conclusion: EUS is considered as a minimally invasive
method with low incidence of complications, allowing
exact determination of the site and size of stones with
good diagnostic performance.
