摘要
背景:功能性消化不良(FD)是临床上常见的症候群,其发病机制目前尚未完全阐明,现逐步认识到胃感觉过敏可能在FD的发病中起着重要作用。目的:探讨FD患者是否存在胃机械感觉过敏,同时了解胃顺应性变化。方法:应用电子恒压器对52例FD患者和15名健康对照者进行检查,采用恒压梯度扩张法扩张近端胃,获得胃机械扩张感知、不适、疼痛的压力和容积阈值,计算近端胃顺应性。结果:FD患者与健康对照者相比最小扩张压(MDP)无显著性差异;FD患者对胃机械扩张刺激的感知阈值、不适阈值、疼痛压力阈值均较健康对照者显著下降,40.4%的患者胃感知感觉过敏,46.2%的患者胃不适感觉过敏,51.9%的患者胃疼痛感觉过敏;FD患者胃感知和疼痛容积阈值较健康对照者显著降低。FD患者近端胃顺应性与健康对照组相比无显著性差异(P>0.05)。胃机械感觉压力阈值与近端胃顺应性无关。结论:部分FD患者中存在着胃机械感觉过敏,近端胃顺应性正常。
