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

#4055

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<10mm, as they carry a low risk of metastases. However, in clinical practice, the removal of unrecognized rNETs can take place with simple techniques and without preliminary staging.

Aim(s): To report our own experience at a referral center for both NETs and endoscopy.

Materials and methods: Retrospective analyses of polypectomies whose histology revealed an unrecognized rNET. Data on lesions description, endoscopic technique, histology and patients’ follow up (FU) were collected.
