Comparison of endoscopic ultrasonography and digital subtracation angiography in localization of insulinomas / 中国实用内科杂志

ABSTRACT

Objective To compare the value of EUS and DSA in the preopreation localization of insulinomas.Methods Twenty-three cases were examined by ultrasonography(US)and spiral computed tomography(CT),of whom 17 cases were examined by endoscopic ultrasonography(EUS),18 cases were examined by digital subtracation angiography(DSA).The preoperative accurate rates of localizing insulinomas were compared among four methods.Results The detective rate of four methods was 13.3% of US,50.0% of CT,73.9% of EUS and 80.0% of DSA.The sensitivity of EUS was significantly higher than US and CT(P
