Core Tip
Core tip: An analysis of 84 resected lesions of superficial nonampullary duodenal epithelial tumors revealed that preoperative endoscopy and biopsy showed similar accuracies in the diagnosis of carcinoma or adenoma. Endoscopic findings associated with superficial duodenal carcinoma were red color, depression, and mixed-type morphology.
