作者的目的是以非损伤且简便的方法,从多方面检查消化道功能的异常,即采用体外超声波以评价胃和十二指肠的运动功能。方法依 Hausken 等方法,给患者进食清炖肉汤400ml 后,测量胆囊、胃窦部的横断面积,随后,测量十二指肠球部、幽门环,胃窦部的纵断面,进而对此三者的运动,用彩色多普勒法观察十二指肠和胃的逆流现象,最后,测定胃窦部的收缩次数与收缩率,并计算出运动指数(Motility Index)。结果与讨论本技术可对胃排空功能、胃窦部的
The aim of the authors is to examine in many ways abnormalities of digestive tract function in a non-invasive and easy way by using extracorporeal ultrasound in order to evaluate the motor function of the stomach and the duodenum. Methods According to the method of Hausken et al, the patient was given 400 ml of consommé bouillon, and the cross-sectional area of the gallbladder and antrum was measured. Subsequently, the longitudinal sections of the duodenal bulb, pyloric ring and gastric antrum were measured, , The colorimetric Doppler method was used to observe the countercurrent phenomenon of the duodenum and stomach. Finally, the number and contraction rate of gastric antrum were measured, and the Motility Index was calculated. RESULTS AND DISCUSSION This technique can be used to empty the stomach from the function of the antrum
