Gallbladder Motility Study
Time 0 min: Measure GB in long axis and short axis from subxiphoid approach and right intercostal approach. The proper position is maximum size of the GB measure in length apex to cystic duct and maximum width. 2 efficiency clips in long axis sweeping the GB; 1 from subxyphoid and 1 from right intercostal approaches.
Feed the patient 1 can of A/D
Time 15 min: Same 4 images and measurements and GB efficiency 2 clips as at time 0 min.
Time 30 min: Same 4 measurements and GB efficiency 2 clips as at time 0 min. The normal Gb should reduce in size by 25% after 30 min. This is a basis of a study we are doing but from a practical standpoint demonstrates if the GB is working at all. If no movement from cholecystokinin stimulated postprandially, then the GB is dysfunctional and suggests need for removal.
