abstract：BACKGROUND:Preoperative radiologic localization of insulinomas often fails because of the small size of these tumors. Endoscopic ultrasound (EUS) can localize insulinomas in up to 80% of the cases. The aim of this study was to compare EUS and computed tomography (CT) diagnostic accuracy for insulinomas. METHODS:We rev...
