#543 Endoscopic Ultrasound-Guided Fine Needle Tissue Acquisition (EUS-FNTA) Using a 19-G Needle for Histological Grading of Pancreatic Endocrine Tumors (PETs): A Prospective Study

Introduction: EUS-FNTA is increasingly used in the diagnosis of pancreatic endocrine tumors (PETs). Ki-67 expression, an important prognostic factor according to the WHO classification, is difficult to be determined on cytological specimens.

#135 The importance of endoscopic ultrasound in detecting recurrent gastrinoma in a case of MEN 1

Introduction: Approximately 25-30% of patients have gastrinomas as part of the inherited syndrome Multiple Endocrine Neoplasia 1 (MEN 1). Gastrinomas occur in the pancreas, duodenum or peripancreatic lymph nodes. Diagnosis is made by clinical history, gastroscopy, and measurement of serum gastrin, gastric juice pH, CT scan, endoscopic ultrasound (EUS) and somatostatin receptor scintigraphy (SRS). Localization of gastrinomas in patients with MEN 1 is challenging due to their small size, frequent duodenal location, and multiplicity.
