[The effect of bile secretion on duodenal motility and intracavitary pressure].

Open catheters were used to study the interdigestive motoric of the duodenum in 80 patients with chronic noncalculous cholecystitis and 30 patients with postcholecystectomy syndrome. Most frequently the patients showed hypomotor dyskinesias of duodenum (stages I-II) with an increase or decrease of the intracavitary pressure. Liobil produced a stimulating effect on the duodenal motor function. Patients with chronic noncalculous cholecystitis showed a clear increase of the amplitude of intestinal contractions. Patients with postcholecystectomy syndrome revealed after liobil administration an increase of the III phase time. In 9 patients formerly absent spontaneous rhythmic phase appeared.
