实时超声法测定空腹胃窦面积的临床意义

本文利用实时超声法测定了５８例健康人及５９例胃病及糖尿病病人空腹胃窦面积。结果显示，健康中国人胃窦面积为１．５２ｃｍ２±０．４３ｃｍ２，与性别、年龄、身高、体重无关，胃炎、糠尿病、活动期十二指肠溃疡病人空腹胃窦面积均有不同程度扩大，慢性胃炎伴呃逆，腹胀症状及糖尿病病人异常率为１００％。本文中有２２例病人同时做食管测压检测，结果显示溃疡病病人空腹胃窦面积与食道上、中、下段压力均无关，糖尿病、胃炎病人胃窦面积与ＬＥＳＰ呈负相关。此研究结果提示空腹胃窦面积可在某种程度上代表胃排空功能。

Clinical Significance of Fasting Antral Area Measured by Real Time Ultrasonography

By means of real time ultrasonography,we measured fasting antral area in 59 patients with gastric diseases and diabetes and 58 normal controls.The results showed that the antral area were 1.52cm 2±0.4cm 2,which had no association with sex,age of high.But fasting antral area in patients with duodenal ulcer,diabetes and Chronic gastritis were significantly larger than that in the controls.The variation rate was 100 per cent in diabetes and chronic gastritis with hiccup and abdominal distention.Furthermore,esophageal manometry was performed on 22 of 58 patients.The results demonstrated that the fasting antral area in duodenal ulcer patients did not associate with pressures of upper,middle and lower esophagus,but in patients with diabetes and chronic gastritis patients had negative correlation with lower esophagealsphincter pressure (LESP).Our results suggested that in some cases fasting antral area can reflect the function of gastric empty.
