We developed a jelly infusion method (J-method) and a balloon method (B-method) enabling the evaluation of the duodenal ulcer, then we made a comparison between detection rates of duodenal ulcers by J-method and that of B-method. From October 1993 to March 1994, ultrasonic probe (USP) were performed in 67 lesions of duodenal ulcers (17 single ulcers, 50 multiple ulcers) using these methods. Detection rates of single duodenal ulcers were satisfactory good using both methods. Detection rates of posterior ulcer in multiple duodenal ulcers were 42% using J-method and 79% using B-method, respectivelly. The results indicate that J-method is suitable for detecting single duodenal ulcer and B-method is suitable for detecting multiple duodenal ulcers.
