Complete Mesenterial Venous Obstruction – A Clinical Syndrome Unique to Neuroendocrine Neoplasms of the Small Bowel Abstract #839

Introduction: Neuroendocrine neoplasms of the small bowel are mostly advanced or metastasized at diagnosis. Metastases typically occur in the mesenteric root and liver.
Aim(s): We report clinical presentation and interdisciplinary management of cachexia and malnutrition caused by complete mesenteric venous occlusion due to mesenteric lymph node metastases.
Materials and methods: Between 12/2011 and 09/2012, three patients with obstructing lymph node metastases in the mesenteric root were diagnosed due to malnutrition and typical thickening of the small bowel with ascites, which was caused by dual obstruction of superior and inferior mesenteric veins without development of extra-splanchnic circulation. These patients showed no signs of liver metastases. In the same period, control patients were identified with mesenteric obstruction and extra-splanchnic circulation or with sole obstruction of the mesenteric or portal vein.

#14 Radioguided surgery in NET: First impression with Ga-68 labeled somatostatin analogues
Introduction: Neuroendocrine tumors (NET) constitute a heterogenous group of neoplasms. The development of Gallium-68-labeled somatostatin analogues, such as DOTA-NOC or DOTA-TOC, PET/CT have dramatically improved the diagnosis of neuroendocrine tumors. Surgery remains the treatment of choice for localized disease as well as metastatic disease. The aims of surgery are: improvement of symptoms, reduction of tumor mass / burden and to give better quality of life to patients. Recurrent laparotomies often lead to multiple adhesions and altered anatomy. So it is increasingly difficult for imaging physicians and surgeons to separate non-malignant from malignant tissue.

#571 Safety and Efficacy of Peptide Receptor Radionuclide Therapy after Liver Transplantation in Metastatic Neuroendocrine Tumors
Introduction: Liver transplantation is an important option for patients of neuroendocrine tumors (NET) with metastases limited to the liver. Peptide receptor radionuclide therapy (PRRNT) is effective in the management of metastatic NET.

#567 Efficacy of Combined Peptide Receptor Radionuclide Therapy and Radiofrequency Ablation for the Management of Hepatic Metastases of Neuroendocrine Tumors
Introduction: Hepatic metastases significantly affect the overall prognosis and quality of life in patients with gastroenteropancreatic neuroendocrine tumours (GEP-NET). Radiofrequency ablation (RFA) is one of the important local ablative strategies for hepatic metastases. Peptide receptor radionuclide therapy (PRRNT) is a well-established therapeutic modality for metastatic NET.

#167 Localization of Sporadic Neuroendocrine Tumors by Gene expression Analysis of Their Metastases
Introduction: Primary neuroendocrine tumors (NETs) are rare and often difficult to detect, leading to diagnosis late in their development. Cases in which the primary cannot be located are denoted as CUP-Syndrome.
