A 69-year-old man presented to our hospital with the chief complaints of vomiting and right hypochondrium pain. Upper gastrointestinal endoscopy showed a stage-A2 ulcer on the expanded pyloric ring and a funnel-shaped stenosis adjacent to the ulcer. The stenosis extended from the lesser curvature of the duodenum to the anal part of the duodenum. The papilla of Vater existed adjacent to the stenosis. The bulb and the proximal descending limb of the duodenum were markedly extended like a pouch. Because the bile duct, pancreas, pancreatic duct, and colon were normal on radiological studies, congenital duodenal stenosis was suspected. We assumed that there was duodenal stenosis on the anal side of the papilla of Vater and that shortening of the duodenum was caused by recurrent peptic ulcer and stagnation of stomach and duodenal contents due to stenosis.
