Ileal reservoirs: an experimental study of motility in the Kock and triplicated pelvic ileal pouches.

Motor activity in the Kock ileostomy reservoir and the triplicated pelvic ileal reservoir was studied experimentally in dogs and compared with normal terminal ileum under identical conditions. Despite claims to the contrary, both reservoirs possessed significant motor activity under basal conditions and on filling. This was reduced, however, compared with normal terminal ileum. The design of the Kock reservoir does not seem to have any distinct advantages over the triplicated ileal reservoir which may be used either as an abdominal or pelvic pouch.
