#4055 Incidental endoscopic removal of a rectal neuroendocrine tumor: What to do?

Introduction: An increasing incidence of rectal neuroendocrine tumors (rNETs) has been reported as a consequence of the progressive spread of screening colonoscopy. Guidelines suggest endoscopic resection, preferably by endoscopic mucosal resection (EMR) or submucosal dissection, for rNETs

#3667 Outcome of endoscopic submucosal dissection for rectal neuroendocrine neoplasms – A multicentre study

Introduction: Recent guidelines recommend advanced endoscopic resection techniques, such as Endoscopic Submucosal Dissection (ESD), for the treatment of rectal neuroendocrine neoplasms (R-NENs) under 15mm due to high rate of positive margins at Endoscopic Mucosal Resection (EMR).

#3441 Management of type-I gastric neuroendocrine neoplasms: A single center’s real world experience

Introduction: Currently, the optimal management of Type-1 gastric neuroendocrine neoplasms (T1gNENs) remains an active issue. The best endoscopic approach still needs to be defined.

#3145 Reduction of serum insulin levels and diazoxide doses as an effect of PRRT in patients with severe hypoglycemia due to primary non-operative insulinoma

Introduction: Severe hypoglycaemia in a course of inoperable insulinoma may be life-threating and it is not always well controlled even by high doses of diazoxide, which in some cases cause a significant toxicity. Nowadays, other forms of effective therapy are not available - use of protein kinase inhibitors (everolimus, sunitynib) sometimes bring satisfactory effect but is often associated with the risk of serious side effects. Use of Peptide receptor radionuclide therapy (PRRT), characterized by relatively low toxicity, is not widely used.

#2929 Type III Gastric Neuroendocrine Neoplasms: Is Local Excision Sufficient in Selected Cases?

Introduction: As per ENETS Guidelines, patients with type III gastric neuroendocrine neoplasms (t-III g-NEN), need to undergo partial or total gastrectomy. Data for less-extensive resections are limited.
