Superior Mesenteric Vein Stenting for Management of Complications of Mesenteric Desmoplasia in Midgut Neuroendocrine Tumors

#984

Introduction: Mesenteric fibrosis is a cause of morbidity and mortality in patients with midgut neuroendocrine tumors (mNETs). It may cause occlusion of the superior mesenteric vein (SMV), which can be associated with development ascites and mesenteric and small bowel varices (SBVs) leading to occult gastrointestinal (GI) bleeding.

Aim(s): To investigate the role of SMV stents in management of ascites and SBVs in mNETs patients.

Materials and methods: Five patients (three male, two female) were included. All patients had G1 mNETs, and evidence of inoperable mesenteric disease, desmoplasia and SMV occlusion.
