Abstract:
Objective: To determine the value of CT,DSA,endoscopic ultra sonography(EUS),and a combined protocol for preoperative detection of insulinomas.Methods : We retrospectively studied data from 15 patients with insulinomas who underwent EUS,CT and DSA from 2000 to 2005.All patients were treated surgically.Results: The overall diagnostic sensitivity for helical CT was 36.3%.Endoscopic sonography and DSA showed sensitivity were 72.7% and 80.0% respectively.The overall diagnostic sensitivity for combined helical CT and endoscopic sonography was 72.7%,which was not statistically significant.The sensitivity for combined EUS and DSA was 93.3%,which was statistically significant.Conclusion: EUS is important to detect insulinomas,and the most effective method for revealing insulinomas is a combined imaging protocol that consists of both EUS and DSA.
