[Electrical control activity during and after mechanical ileus--an animal experimental study on the reversibility of ileus-induced motility disorders].

The electrical control activity in the pre- and poststenotic intestine segment was recorded in rabbit during a mechanical high-located small-bowel ileus of 24 hours duration and after its release. The ligature of the intestine caused an immediate decrease of frequency in the poststenotic segment and in the prestenotic segment only after an ileus duration of 24 hours. The sw-frequencies (slow waves) normalized themselves in both bowel segments after the removal of the occlusion 48 hours later. The control activity in the control group of sham-operated animals normalized itself after a transitory decrease already 24 hours later.
