[The interdigestive motility of the gallbladder in patients with gastric and duodenal peptic ulcer].

As many as 30 patients with uncomplicated ulcer disease and 8 essentially healthy individuals were studied for the tone and contractile function of the gallbladder under basal conditions with regard to the phases of duodenal interdigestive motility. In normals, the gallbladder functions according to phases of duodenal interdigestive motility while the clinical picture in those patients with ulcer disease is distinguished by predominance of hypermotor dyskinesia of the gallbladder and bile tract, which fact is manifested by reduction of its capacity as well as hypertone and discordant work of Lütken's--and Oddi sphincters leading to untimely and incomplete outgo of the bladder bile. Ultrasonic investigation of the gallbladder is to be carried out with due regard to its phase-associated interdigestive motility.
