The electrode is built into a rubber ballon and inserted into the rectum or sigma. When the balloon is inflated the tip of the electrode touches the mucous membrane. A pen-writing oscillograph is employed to record this current. The time constant is 0.05 seconds.
The recorded pattern by this method is similar to that obtained from the outside of intestinal wall with the previously employed method. Three types of spike patterns corresponding to the macroscopical movement, i. e., pendular movement, peristaltic movement, and spastic contraction, can be observed in human subject.
The significanse of the slow wave has not been definitely clarified yet, therefore the spike and its group are being studied.
It is believed that this method is superior to the usual mechanic kymogramm for recording intestinal movements in situ.
The recorded data in the megacolon patients and some cases of neurovegetative disorders in abdomen are presented and discussed.
