#2753 Risk of PRRT-Associated Bowel Obstruction in Patients with Mesenteric/Peritoneal Disease and Potential Role of Corticosteroids in Treatment

Introduction: Although radiation-induced mesenteritis or peritonitis can potentially exacerbate risk of bowel obstruction, there are no data in the literature on incidence of intestinal obstruction related to peptide receptor radiotherapy (PRRT)

#423 Case Report : A Rare Cause of Retroperitoneal Fibrosis Responding to Steroids

Introduction: Retroperitoneal fibrosis is a rare inflammatory disease. Neuroendocrine tumors are a heterogenous group that arise from enterochromaffin cells, most commonly in the gastrointestinal tract. Their capacity to secrete hormones, five HT, tachykinins etc, are responsible for symptoms known as carcinoid syndrome. However NETS, particularly arising from the midgut, can cause fibrosis. This can result in bowel obstruction, but also cause fibrosis in the retroperitoneum, lungs and cardiac valvular fibrosis.
