In the last 2 years, we experienced 18 cases of postbulbar duodenal ulcer. The analysis was made on clinical, radiographic and endoscopic findings of the disease. 1) In our series of 18 cases, there were 17 men and 1 woman. The average age was 42.6. 2) As a complication of this disease, bulbar ulcer were seen in 55.6% and gastric ulcer in 11% of all cases. 3) As the radiographic findings, ring stricture were seen in 94.1% and nische in 76.5% of 17 cases. Barium-filled image in the restand right anterior oblique projection was more effective than another image, and hypotonic duodenography was very useful technique in diagnosing of this disease. 4) Endoscopically, these ulcers were confirmed in 75% of all cases. In order to observe the ulcer in detail it is important to use both of the side-viewing type and the end-viewing type of the small caliber duodenofiberscope, depending upon choice.
