Abstract: Objective To compare the value of contrast-enhanced ultrasonography (CEUS) with that of laparoscopic ultrasonography (LUS) in localization diagnosis of insulinoma. Methods Thirty-three patients with insulinoma,who received operation, were retrospectively reviewed. All cases were examined by both CEUS and LUS before the tumor removed. Both imaging modalities in diagnosis of insulinoma were analyzed. Results By this study the sensitivity and accuracy of CEUS were 92.31% and 90.0% respectively. Those of LUS were consistent with pathologic findings completely. The accuracy of CEUS was not different with that of LUS (χ2 = 4.21, P = 0. 04). Conclusions CEUS can be used for location diagnosis of insulinoma. For the patients expecting laparoscopic treatment, combination of CEUS with LUS will be suggested before insulinoma is removed.
