Core Tip
Core tip: Because superficial non-ampullary duodenal epithelial tumor is rare, a preoperative endoscopic diagnostic technique to differentiate between adenoma and adenocarcinoma has not yet been established. Recently, many new imaging modalities have been developed and explored for use in the real-time diagnosis of these types of lesions. Newer endoscopic techniques, including magnifying endoscopy, may help to guide these diagnostics, but their additional advantages remain unclear, and further studies are required to clarify these issues.
