We induced the rectoanal reflex electrically in three groups of children, following rectal dilatation with a balloon. In normal children, and in children with constipation or ileus due to causes other than Hirschsprung's disease, the rectoanal reflex was induced by electric stimulation as well as by dilatation of the rectum with a balloon. In children with Hirschsprung's disease, however, no typical reflex was obtained by either of these stimuli. Since electric stimulation does not dilate the rectum, passive dilatation of the anus or shift of the probe along with balloon expansion does not take place, so no false-positive reflex is elicited. Electric current, moreover, is capable of providing a constant quantifiable stimulus. We have demonstrated the induction of the rectoanal reflex by electric stimulation alone; distention of the circular muscle of the rectum does not appear necessary for the induction of this reflex.
我们在三组儿童中通过用球囊扩张直肠后进行电刺激来诱发直肠肛门反射。在正常儿童以及因非先天性巨结肠病的其他原因导致便秘或肠梗阻的儿童中，直肠肛门反射可通过电刺激以及用球囊扩张直肠来诱发。然而，在患有先天性巨结肠病的儿童中，这两种刺激均未引出典型反射。由于电刺激不会扩张直肠，肛门不会出现被动扩张，且探头不会随着球囊扩张而移位，因此不会引出假阳性反射。此外，电流能够提供恒定的可量化刺激。我们已经证明仅通过电刺激就能诱发直肠肛门反射；诱发该反射似乎并不需要直肠环行肌的扩张。
