Abstract
Background and study aim. Endoscopicultrasound (EUS) is a diagnostic modality that continuesto expand its clinical applications. The aim of this studyis to evaluate the diagnostic role of EUS in commonbile duct stones. Patients and methods: This study wascarried on 29 patients with suspected CBD stones fromthem only 15 patients were diagnosed as Common BileDuct stone(s). Endoscopic retrograde cholangiopancreatography(ERCP) is considered as gold standard fordiagnosis of CBD stones and compare EUS findingswith that of ERCP. Results: The diagnostic performanceof EUS shows that the sensitivity, specificity, PPV, NPVand accuracy of 100%, 92.8%, 93.7%, 100% and 96.5%respectively. It can catch 15 true positive cases withonly one false positive case and 13 of 14 true negativecases. EUS is considered as a minimally invasivemethod with low incidence of complications, allowingexact determination of the site and size of stones. SoEUS aid in better planning for CBD stone removal.Conclusion: EUS is considered as a minimally invasivemethod with low incidence of complications, allowingexact determination of the site and size of stones withgood diagnostic performance.
