#2288 Predicting Resectability of Primary Tumor and Mesenteric Lumps in Patients with Small Intestine Neuroendocrine Tumors
Introduction: Vascular infiltration and mesenteric fibrosis may jeopardize resection of primary tumor (PT) and mesenteric metastatic lumps (MLs) in small-intestine neuroendocrine tumors (SI-NETs).

#1216 Mesenteric Ischemia Due to Neuroendocrine Tumors of the Digestive Tract
Introduction: Mesenteric ischemia (MI) is a poorly known complication of neuroendocrine tumors (NETs).

#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.

#1113 A Novel Approach for a Metastatic Gut-Derived Neuroendocrine Tumour: Simultaenous Intestinal and Vascularised Sentinel Forearm Flap Transplantation
Introduction: Non-resectable tumours involving the mesenteric root are an indication for intestinal and multivisceral transplantation (MVT). Vascularised sentinel forearm flaps (VSFF) offer possibilities for monitoring graft rejection and tailoring immunosuppression (IS) regimens.

#1558 Multivisceral Transplantation and Vascularised Sentinel Forearm Flap for a Metastatic Gut-Derived Neuroendocrine Tumour: Follow-up
Introduction: We previously reported the first documented case of a novel approach in a patient with extensive mesenteric metastases from a small bowel (SB) NET: this combined multivisceral transplantation (MVT) and a vascularised sentinel forearm flap (VSFF) from the same donor.

#1816 Multivisceral Transplantation and Vascularised Sentinel Forearm Flap for a Metastatic Small Bowel Neuroendocrine Tumour: Update on Follow-Up
Introduction: We previously reported the first documented case of a novel approach in a patient with extensive mesenteric metastases from a small bowel neuroendocrine tumour (SBNET): this combined multivisceral transplantation (MVT) and a vascularised sentinel forearm flap (VSFF) from the same donor.

#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.

#1136 Small Bowel Neuroendocrine Tumors (NET): Relationship Between Radiologic Features, Functionality and Ki-67 Classification.
Introduction: Since small bowel NETs are usually small tumors, detection and characterization of metastatic affection plays an important role.

#2095 Progression of Mesenteric Metastasis in Small Intestinal Neuroendocrine Tumors
Introduction: A metastatic mesenteric mass is a hallmark of small intestinal neuroendocrine tumours (SI-NETs). However, little is known about the development of a SI-NET associated mesenteric mass over time.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.
