[The interdigestive phasic motility of the gallbladder and bile excretion in healthy subjects and in patients with duodenal peptic ulcer].

Interdigestive phasic motility of the gallbladder and bile excretion into the duodenum were studied in 100 patients with duodenal ulcer (DU) and 20 healthy subjects. Gall bladder motility and bile excretion in both healthy and DU subjects directly depended on interdigestive phasic activity of the duodenum and gastric antrum. In health, gallbladder volume reached its maximum within termination of phase II, minimum in the end of phase III-beginning of phase I. Maximal bile production occurred at phase II-III and coincided with pH decline in the stomach. The mixture of the vesicular and duct bile flowed out in the end phase III-beginning of phase I. The range of volumetric bladder contraction made up 33% of its capacity. In DU patients this reached 35%, the bladder capacity was reduced, the maximum bile production occurred at phase II, bile flowed out intermittently, its color changed from achromatic to dark yellow. The latter fact suggests hypertensive and hypermotor dyskinesia of the gallbladder as well as its sphincter system and bile duct functional impairment. This requires adequate therapeutic correction with consideration of relevant motor and secretory disturbances.
