Skin electrogastrogram was made in 40 healthy controls and 32 patients with ulcerative pyloroduodenal stenosis in fasting condition and after mixed meal. Fasting frequency of gastric bioelectric activity (BA) was similar in the patients and the controls (2.65 +/- 0.008; 2.65 +/- 0.008; p < 0.01). BA frequency unstability factor (FUF) was not so high in patients compared to controls (13.9 +/- 0.07; 15.3 +/- 0.11; p < 0.01). The meal produced a significant rise in the frequency, amplitude and a decrease in FUF of gastric BA in the patients and controls but in patients a fall in FUF was greater. A rise in the amplitude of gastric BA in patients was more pronounced than in controls (250.6 +/- 5.17%, 162.0 +/- 2.23%; p < 0.01). In patients the amplitude increased greater in compensated stenosis, weaker--in decompensated stenosis. The changes in gastric BA amplitude varied with severity of pyloroduodenal stenosis.
在40名健康对照者和32例溃疡性幽门十二指肠狭窄患者空腹及进食混合餐后进行皮肤胃电图检查。患者和对照者空腹时胃生物电活动（BA）频率相似（2.65±0.008；2.65±0.008；p<0.01）。与对照者相比，患者的BA频率不稳定因子（FUF）不那么高（13.9±0.07；15.3±0.11；p<0.01）。进食后，患者和对照者的胃BA频率、振幅显著升高，FUF降低，但患者的FUF下降幅度更大。患者胃BA振幅的升高比对照者更明显（250.6±5.17%，162.0±2.23%；p<0.01）。在患者中，代偿性狭窄时振幅增加更大，失代偿性狭窄时较弱。胃BA振幅的变化随幽门十二指肠狭窄的严重程度而异。
