Ligation-assisted endoscopic mucosal resection for duodenal neuroendocrine tumor.

Endoscopic treatment has become a preferred method for neuroendocrine tumors (NETs) of the gastrointestinal tract.Here we report a 72-year-old female with a duodenal neuroendocrine tumor treated by ligation-assisted endoscopic mucosal resection. This treatment was effectively used to cure the duodenal NETs and ensured complete resection without residual positive margins. This case report is rare.
