Analysis and classification of functional dyspepsia / 中国综合临床

ABSTRACT

Objective To investigate the proportions of the functional dyspepsia (FD) subgroups and to explore theri relationship with Helicobacter pylori (HP).Methods 186 cases with FD received questionaires about their condition and were typed according to their symptom.HP was detected through urease test,spear technique and cultivation.Results The proportion and HP-positive rate of the subgroup were 11.29%,14.24% in reflux-type dyspepsia,13.98%,46.15% in ulcer-type dyspepsin,48.39%,41.11% in dysmotility-type dyspepsia and 26.34%, 38.78% in complex dyspepsia,respectively.The total HP-positive rate of FD is 38.17%.Conclusion Dysmotility-type dyspepsia is most common.Some subgroups are overlapping with each other.There is no relationship between FD and HP.The HP-positive rate of the reflux-type dyspepsia is lower.This observation suggests that HP may have protective effects on esophagus.
