#3022 Diagnostic Accuracy of 68Gallium Positron Emission Tomography (68Ga PET), Endoscopic Ultrasound (EUS) and Computed Tomography in the Assessment of Lymphnode Metastases by Nonfunctioning Pancreatic Neuroendocrine Neoplasms

Introduction: The presence of nodal metastasis is one of the most important predictive factors for recurrence after radical surgery for nonfunctioning Pancreatic Neuroendocrine Neoplasms (NF-PanNEN). Nevertheless, it is not clear which is the best diagnostic examination to identify preoperatively lymphnodal metastasis.

#2118 Reassessment of Risk Factors Associated with Locoregional Lymph Nodal Metastases in Well-Differentiated Appendiceal Neuroendocrine Neoplasms

Introduction: To prevent loco-regional recurrence and subsequent development of distant metastases in Appendiceal Neuro-Endocrine Neoplasms (ANEN), the existing Guidelines have identified risk factors which would indicate a prophylactic right hemicolectomy(RHC).

#2096 The Number of Positive Nodes Accurately Predicts Recurrence after Pancreaticoduodenectomy for Nonfunctioning Neuroendocrine Neoplasms

Introduction: The presence of lymph node metastases is one of the most powerful predictor of recurrence after surgery for pancreatic neuroendocrine neoplasms (PanNENs), but the most appropriate nodal staging for PanNENs is unclear.

#2057 Morphological Factors Related to Nodal Metastases in Neuroendocrine Neoplasms of the Appendix. A Multicenter Retrospective Study

Introduction: Appendiceal NETs are usually diagnosed accidentally after appendectomy; the indications for right hemicolectomy are currently based on several parameters (tumor size, grading, Ki-67, localization, mesoappendiceal invasion, lympho-vascular infiltration). Available guidelines are based on scarce evidence inferred by small, retrospective, single institution studies.

#1006 The Use of Endoluminal Stents to Overcome Vascular Obstruction Arising from Mesenteric and Retroperitoneal Neuroendocrine Metastases

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NET) often metastasise to lymph nodes. Nodal metastases from neuroendocrine tumors in the distal small intestine commonly (>50%) develop in the mesentery and are often centred at the mesenteric root surrounding the major vessels supplying the bowel. Compression of these vessels, by the nodes or associated fibrosis, can lead to severe symptoms such as pain (secondary to bowel ischaemia ), ascites (from superior mesenteric vein obstruction) and bowel perforation. In view of the often indolent nature of GEP-NET, symptoms from lymph node masses can persist for years, causing significant morbidity and early mortality.
