FD患者胃十二指肠运动功能的研究

Study on gastric and duodenal motility in patients with functional dyspepsia

目的通过胃窦十二指肠压力测定，研究功能性消化不良（ＦＤ）患者胃十二指肠的运动功能．方法ＦＤ患者２８例，健康人１３例．采用导管灌注技术测定胃窦和十二指肠的腔内压，消化间期测压３５ｈ，餐后测压１５ｈ．结果在消化间期，２８例ＦＤ中１３例未出现移行运动复合波（ＭＭＣ）３期，１３例健康人１例未出现ＭＭＣ３期，两者相比有显著性差异（Ｐ＜００５）；ＭＭＣ２期和３期收缩的平均频率、平均强度和动力指数，在ＦＤ患者和健康人间相比无差异（Ｐ＞００５）．ＦＤ患者餐后胃窦收缩的频率、强度和动力指数均低于健康对照组（Ｐ＜００５）．结论ＦＤ患者消化间期缺乏ＭＭＣ３期或ＭＭＣ３期延迟出现，餐后胃窦动力减低．

AIM To study the gastric and duodenal motility in patients with functional dyspepsia (FD) by using antroduodenal manometry. METHODS In 28 patients with FD and 13 healthy subjects, antroduodenal intraluminal pressure was measured by catheter perfusion technique. Interdigestive motility was recorded for 3 5 hours and postprandial motility for 1 5 hours.
