Gall bladder emptying in severe idiopathic constipation

Abstract

Patients with slow transit constipation have smaller fasting gall bladder volumes, impaired gall bladder responses to vagal cholinergic stimulation, but normal gall bladder responses to hormonal stimulation with CCK. These results point to abnormalities in gastrointestinal motility proximal from the colon in slow transit constipation and more specifically, impaired neural responsiveness.
