Title: Evaluation of the contribution of endoscopic ultrasonography to the diagnosis of pancreatic endocrine tumor——insulinoma
Abstract: Objective To assess the clinical diagnostic value of endoscopic ultrasonography (EUS) in preoperative localization of pancreatic endocrine neoplasm——insulinoma by comparing with the conventional imaging procedures. Methods Six patients with insulinoma diagnosed by clinical and laboratory findings were assessed with US, CT and EUS to detect the pancreatic lesions before surgical intervention. All the cases then received laporatomy and tumors were examined by histological study. Results In six cases, seven lesions were found in pancreas by surgical procedures, the diagnostic detectability of pancreatic neoplasms by US, CT and EUS being 14.3% (1/7), 57.1% (4/7) and 85.7% (6/7) respectively. The diagnostic accuracy of insulinoma by EUS was 83.3% (5/6) as compared with histological study. However, the diagnostic detectability of site and size of pancreatic lesions by EUS was in accordance with that of surgical results. Conclusions EUS is superior to conventional image examinations in preoperative localization of pancreatic neoplasma and is a feasible and effective procedure in clinical diagnosis of insulinoma.
