Background : Dyspepsia is common in clinical practice with frequent relapses and often requires multiple
investigations to assess intraluminal and extraluminal etiologies. Endoscopic ultrasound (EUS) has the
potential of serving both purposes in a single setting.
Materials and Methods : Patients with dyspepsia who underwent EUS in four-year period were retrospectively
reviewed. Diagnostic findings of EUS, final diagnoses were noted and compared with the reference standards.
Results : 131 patients with a mean age + SD of 50 + 12.7 years were included. The common diagnoses were
non-ulcer dyspepsia in 56%, symptomatic gallstone (GS) in 22.9%. EUS detected two GS missed by transab-
dominal ultrasound (TUS). EUS missed one GS documented by surgery. EUS detected seven cases of ERCP-
proven CBD stones undetected by TUS and had a sensitivity, specificity, positive predictive value and negative
predictive value for CBD stones of 87.5%, 91.7%, 87.5%, and 91.7% respectively.
Conclusion : EUS is a potential investigation for the management of dyspepsia.
