Electrical activity and motility in the isoperistaltic side to side ileal reservoir

In ten rabbits, electrical activity and motility were measured in a side to side isoperistaltic ileal reservoir of 10 centimeters up to three months postoperatively and compared with normal ileum in three rabbits in the control group. Synchronous short spike wave complexes appeared across the reservoir anastomosis early postoperatively; however, they were not associated with propulsive peristaltic waves. Long intense spike wave complexes were associated with propulsive peristaltic waves in the rabbit ileum. These complexes appeared within two weeks postoperatively; however, they were initially asynchronous across the anastomosis. Within three months postoperatively, these complexes became synchronous across the anastomosis, indicating near normal propulsive function in the reservoir.
