[Electromyography studies of gastrointestinal obstruction zones. An animal experiment study]

Abstract

In experiments on animals the function of cardia, pylorus and ileocecal valve was characterized electromyographically. Under non-pathologic conditions a reflux in the cardia and ileocecal region cannot be expected; the pylorus permits a physiological reflux between duodenum and stomach. A connection to other reflux-dependent pathological processes is discussed.
