Neuroendocrine tumor of the ampulla of Vater treated with endoscopic papillectomy: A case report

This is the authors' abstract. We don't add key points for this paper.

We report the case of a 62-year-old female with a 6.3-mm low-grade neuroendocrine tumor of the ampulla of Vater, who underwent an endoscopic papillectomy. An endoscopic papillectomy was performed without complications. In the 26 months of follow-up, no local recurrence or metastasis occurred. Endoscopic treatment of ampullary neuroendocrine tumors is controversial. However, endoscopic papillectomy may be considered a treatment option if neuroendocrine tumors are small (<10 mm), have a low grade (G1), or do not have muscle layer or bile duct invasion.
