Abstract
Using computer-assisted scintillation camera imaging bile duct dynamics was studied in 28 patients with a nonvisualizing gallbladder due to acute cholecystitis. Postoperative repeatstudies were carried out in 8 of the 28 patients. In half of the studies three accumulations of activity were evident on the 60 added 1-min views. These three accumulations were interpreted as corresponding to the biliary tree. An explanation for the separation of the activity into three depots, is proposed.
Analysis of the time-activity curves of the accumulations showed an irregular exchange of activity, suggesting intracholedochal movements of bile. Passage of bile from the common duct into the duodenum was observed 1–7 times during the 1-h studies. In most studies the bulk of the activity was caught by an antegrade peristaltic wave as soon as it left the duct. The activity was then transported rapidly in a medial direction. This finding suggests that relaxation of the sphincter occurs in phase with duodenal peristalsis.
