According to the World Health Organization (WHO) 2010 classification, neuroendocrine tumors (NETs), especially WHO grade Gl, correspond to neoplasms formerly termed as 'carcinoid tumor'. Duodenal NETs are rare tumors, and not only the knowledge of their endoscopic and physiologic characteristics but also an accurate endoscopic technique are required for precise diagnosis. Regarding the treatment strategy for duodenal NETs, surgical resection is recommended for gastrinomas and ampullary NETs, while the therapeutic approach for non-ampullary NETs depends on its size. However, currently there is no standardized treatment strategy for NETs ≤ 20 mm in diameter. In the present paper, we describe the optimal endoscopic technique, key diagnostic points, and treatment for duodenal NETs as well as summarize the current knowledge on NETs.
