 Intraluminal duodenal diverticulum, formerly considered as of rare occurrence, has been reported with increasing frequency since communications of Schmidt (1941),Nelson (1947) and Kinzer (1949). To the best of our knowledge,38 cases of this anomaly have been described in America and Europe, but never in Japan.

 This is a report of a intraluminal duodenal diveticulum including its typical radiographic features and operative findings encountered in 38-yearoid man who had been complaining of epigastric pain for several years. An upper gastrointestinal x-ray series (Figs. 1 and 2) demonstrated a peculiar defect extending from the mid-descending duodenum into the pars horizontalis. As he had continued symptoms in spite of medical management, he underwent surgical exploration on May 22, 1969.

 Pathognomonic roentgen features of intraluminal diverticulum are demonstrated in Figs. 1 and 2. X-ray picture shows a smooth, pouch or pear-like barium-filled structure within the lumen of the bowel (Figs. 3, 4 and 5) The wall or sac of the diverticulum is readily outlined as a thin translucent zone 1~2 mm thick surrounding the diverticulum except at the base of its attachment, which is found in the descending limb of the duodenum (Figs. 6 and 7).

 The duodenum was mobilized by Kocher's maneuver and opened. The diverticulum was immediately apparent resembling a finger of a glove (Fig.8). It was related cosely at its origin to the supra-ampullary region (Fig. 9). Simple excision of the diverticulum at its base was carried out and duodenal ulcer being associated, gastrectomy and gastroduodenostomy were performed as well.

 The postoperative course was uneventful. He was discharged symptom-free on July 7, 1969.

 The histologic appearance of the diverticulum is that of normal duodenal mucosa lining both sides of the sac. A small amount of incomplete muscularis mucosae and fibrous tissue is seen (Fig. 10 and 11).
