| [ Summary ] | Recent developments in endoscopic technology including high-resolution and image-enhanced endoscopy may improve the detection rates of superficial non-ampullary duodenal epithelial tumors (SNADETs). However, because SNADETs are rare, limited data is available regarding their preoperative endoscopic diagnosis. This review describes the current state of knowledge regarding the diagnostic performance of magnifying endoscopy using narrow band imaging in the diagnosis of SNADETs, such as non-neoplastic lesions, duodenal adenomas, and adenocarcinoma. Newer endoscopic techniques including magnifying endoscopy may help as guides to these diagnostic modalities, although their additional advantages remain unclear, and further studies are required to clarify these issues. | |
