[Methods of studying motor function of the small intestine at a surgical clinic]

On the basis of 200 many-hours investigations of motor function of the duodenum and jejunum performed in experiments and clinic with the help of polydigestograph "Express-MT" five degrees of its activity were established: negative, relative rest, weak, medial and strong. High exactness of the registration of intestinal motility at the early period after operations on the abdominal organs was proved. It was found that no complete extinction of the motor function of the small intestine was observed even under conditions of diffuse peritonitis.
