RESUMO
Stenosing papillitis is a descriptive term for an anatomic deformity of the Ampulla of Vater due to chronic inflammation and fibrosis, which is characterized by narrowing of the lower end of the bile and pancreatic duct, and by clinical symptoms resembling pancreticobiliary disease. Duodenoscopic finding of "stenosing papillitis" usually shows edema, erythema, and laceration on Ampulla of Vater, but endoscopic finding such as polypoid mass is rare. We recently experienced one case of polypoid stenosing papillitis and report with a review of relevant literatures A 54-year-old man was admitted to our hospital because of chronic right upper abdominal pain for 2 years. Duodenoscopy re-vealed a polypoid mass with erythemaous color change on Ampulla of Vater, which was endoscopically resected by using a polypectomy snare, and pathologic examination showed chronic inflammation and fibrosis.
