结肠活动的研究虽多,但是确定其正常的活动类型较胃肠道其他部位更为困难。X光观察因研究对象遭受X线照射而有明显局限性,且难以作定量比较。最常用的方法为肠腔内压力测定。多年应用的气囊法问题很多,最近将开口管与变频器连接并用放射遥测胶囊记录近端结肠的压力,但胶囊定位困难,且大多不能控制 Although there are many studies on colonic activity, it is more difficult to determine the normal type of activity than other parts of the gastrointestinal tract. X-ray observation due to X-ray irradiation subjects have obvious limitations, and difficult to make a quantitative comparison. The most common method is the determination of intestinal pressure. Many years of applied balloon methods are problematic and recently the open tube was connected to a frequency converter and the pressure of the proximal colon was recorded using a radiotelemetric capsule but positioning of the capsule was difficult and mostly uncontrollable
