Cystic neuroendocrine tumor of the pancreas: A rare type of pancreatic cystic lesion accurately diagnosed and staged by EUS-FNA

Abstract

without dysplasia. Immunohistochemical staining for p53 and Ki67 were negative. Patient is scheduled for repeat pancreatoscopy surveillance in 6 months. Main duct IPMN carries a signifi cant risk of malignant transformation. Total pancreatectomy is a morbid procedure, and oft en surgeons choose to remove area of dysplasia leaving non-dysplastic IPMN in the remaining duct. We present a through-the-colonoscope application of SpyGlass system that allows for improved surveillance of patients with residual IPMN. Th is procedure may have wider application in patients aft er Whipple resection.
