Dyspepsia and dyspepsia subgroups in Japan: symptom profiles and experience with cisapride.

In 240 patients with symptoms of dyspepsia, recruited consecutively and investigated in 12 hospitals in Japan, 24.2% were diagnosed having organic dyspepsia; 75.8% had functional dyspepsia, of whom 63.2% were diagnosed by the investigator having dysmotility-like, 13.7% ulcer-like, 11.5% reflux-like, and 11.5% non-specific dyspepsia. There was, however, considerable overlap of symptom profiles. Cisapride therapy initiated in functional dyspeptic patients resulted in moderate or marked improvement in 79.1% of the patients with the highest response rates for dysmotility-like (85.2%), reflux-like (81.0%), and non-specific dyspepsia (76.1%) (versus 52.0% for ulcer-like dyspepsia).
