The possible diagnostic role of endoscopic ultrasound in patients with dyspepsia.
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.


METHODS
Patients with dyspepsia who underwent EUS in four-year period were retrospectively reviewed. Diagnostic findings of US, 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 transabdominal 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.


CONCLUSIONS
EUS is a potential investigation for the management of dyspepsia.
