RESULTS OF ENDOSCOPIC ULTRA SONOGRAPHY IN LOCALIZATION OF PANCREATIC INSULIMONA AND COMPARISON OF INTRAOPERATIVE FINDINGS

The aims of this study were to represent the efficiency of Endoscopic Ultra Sonography in determining the place of insulinoma and assessment communication between tumor size and careful diagnosis of this method. Endoscopic ultra sonography is a method for determining the place of pancreatic tumor before a surgery. Suspected insulinoma patients based on clinical and laboratory entered in this study; all of them underwent Endoscopic ultra sonography investigations before operation. In 16 patients, (9 men and 7 women) with an average age of 52.5 years, sonography and then surgery was done. In all the patients CT scan as a supplementary recognition method was done. Sensitivity and specifity of endoscopic ultra sonography for identifying insulinoma was 70.58 and 60.6 percent and for tumor of head and body of pancreas was 83.3 and 66.6 percent Endoscopic ultra sonography is an accurate method in order to identify insulinoma; the accuracy of the method depends on the tumor site and is greater in tumors that locate in the head of pancreas
