Abstract:
The adenoma of major duodenal pallilla is a rare cause of acute pancreatitis. Also, ampullary adenoma is known as a premalignant lesion having the potential for malignant transformation. Especially, the diagnosis of the unexposed (intramural) type of ampullary adenoma, which shows normal overlying mucosa, is known to be very difficult. We report a case of an unexposed type of ampullary adenoma presented as acute pancreatitis. On duodenoscopic examination, mucocal abnormality of the mapulla of Vater was not noted. After endoscopic sphicterotomy, a nodular mass was exposed and the tubular adeonoma was histologically confirmed with endoscopic biopsy.
