Barostat Motility Description
The Barostat is used to record muscle tone in the GI tract. In patients with motility disorders, the muscle tone is as important as pressure contractions. In patients with gastric-emptying disorders, altered gastric tone is involved controlling liquid gastric emptying, esophageal reflux, and left upper quadrant pain. At CPMC, we have undertaken an aggressive program to treat gastric emptying disorders using gastric pacing and pharmacological agents. The Barostat is important for the evaluation of many of these patients and helps to determine the appropriate course of therapy.
How is a Barostat motility study performed?
Part One: An upper endoscopy must be performed by the doctor to place a guide wire in the farthest point of the duodenum. You will receive conscious sedation for the upper endoscopy. The endoscope is then removed and the motility tube is placed over the guide wire so that one end of the Barostat tube rests at the top part of your stomach while the other end comes out of your mouth. Once the endoscopy is completed and the tube secured in place with tape, you will be moved to a different room where, the Barostat motility tube will be attached to a computer to measure the muscle function in the top part of your stomach.
Part Two: A balloon, that is attached at the end of the Barostat tube, will inflate and deflate many times during your 3.5 hour study. Volume and pressure measurements will be taken as the balloon inflates and deflates during the study. Near the end of the study you will be asked to drink a can of Ensure or Glucerna so that the pressure and volumes measurements can be taken with your stomach partial full.
