Clinical Approaches of Emergencies in Neuroendocrine Tumors

Neuroendocrine tumors (NET) are a rare and heterogeneous group of tumors that represent a wide variety of clinical problems leading to many challenges for the clinician, including several emergencies. In this chapter, we will detail on selection of relevant emergencies that occur as complications of NETs. We will focus on the following topics: carcinoid syndrome, carcinoid crisis, and preoperative, intraoperative, and postoperative management to prevent a carcinoid crisis, carcinoid heart disease, approach of MEN-1, insulinoma, and VIPoma, and at least the challenge of a pheochromocytoma.
