Endoscopic Resection of Ampullary Neuroendocrine Tumor

Intern Med. 2017;56(5):499-503. doi: 10.2169/internalmedicine.56.7520. Epub 2017 Mar 1.


We report the case of a 57-year-old man with a 1.0-cm grade 1 neuroendocrine tumor (G1 NET) of the ampulla of Vater (ampullary NET) who underwent endoscopic snare papillectomy. Pancreatitis occurred after endoscopic resection but was cured with conservative therapy. In two years of follow-up, no local recurrence or metastasis occurred. Endoscopic snare papillectomy for small G1 NET of the ampulla of Vater is relatively safe and less invasive than surgical treatment and should be considered as treatment option.
