To evaluate gastrointestinal motility by abdominal auscultation.
Abdominal auscultated sounds of 20 healthy adults and 10 diabetes mellitus patients with delayed gastric emptying were digitally recorded and then analyzed by computer while simultaneously monitoring the motility of the antrum of the stomach by ultrasonography. The auscultated sound, when the stomach wall was moving, was regarded as the gastroduodenal (GD) sound and when not moving as the intestinal (I) sound. The sound index (SI; the sum of the amplitude) was calculated to indicate the power of sound. Sounds were recorded for 15 min under fasting conditions and 60 min after a liquid meal. In six healthy adults, the gastroduodenal pressure was recorded under abdominal auscultation to detect any correlation between the motility index (MI; the sum of the area under the curve) and SI.
A definite increase in the SI of the GD sound was observed after the liquid meal in comparison with that of the I sound. A positive correlation (r = 0.678) was observed between the SI of the GD sound and MI, thus, it was considered that the GD sound reflected the motility of the gastroduodenal wall. In the diabetes mellitus patients, the SI of the GD sound was significantly lower after food intake than in healthy adults.
The results of the present study indicate that the abdominal auscultation test could be used as a new diagnostic method to detect any abnormality in gastrointestinal motility.
通过腹部听诊评估胃肠动力。
对20名健康成年人及10名胃排空延迟的糖尿病患者的腹部听诊声音进行数字记录，然后由计算机分析，同时用超声检查监测胃窦的动力。胃壁运动时的听诊声音被视为胃十二指肠（GD）音，胃壁不运动时的声音被视为肠（I）音。计算声音指数（SI；振幅总和）以表示声音的强度。在空腹条件下记录15分钟的声音，在进食流食后记录60分钟的声音。对6名健康成年人在腹部听诊时记录胃十二指肠压力，以检测动力指数（MI；曲线下面积总和）与SI之间的相关性。
与I音相比，进食流食后观察到GD音的SI明显增加。GD音的SI与MI之间存在正相关（r = 0.678），因此，认为GD音反映了胃十二指肠壁的动力。在糖尿病患者中，进食后GD音的SI显著低于健康成年人。
本研究结果表明，腹部听诊试验可作为一种检测胃肠动力异常的新诊断方法。
