Antroduodenal Motility Description
A delay in gastric emptying can give symptoms of abdominal bloating or a feeling that the stomach is full soon after beginning a meal. In addition, slow gastric emptying may worsen heartburn since the acid remains in the stomach for a longer time.
There are multiple factors, which influence emptying of the stomach. The stomach must contract in order for the contents to pass into the duodenum, the part of the intestines that is immediately after the stomach. The duodenum, in turn, must not be actively contracting at the same time as the stomach or the progression of the contents will be delayed. The pylorus, which allows passage from the stomach to the duodenum, must be open.
In a patient with delayed gastric emptying, measurement of the pressures in the stomach and duodenum will allow more specific treatment. If the patient has too few contractions in the stomach, there are medicines that can stimulate coordinated contractions in the stomach. If, there are uncoordinated contractions or diminished contractions in the duodenum, there will be different medicines, which can help these patients.
How is antroduodenal motility testing performed?
Part One: An upper endoscopy must be performed to place a guide wire in the farthest point of the duodenum. You will receive conscious sedation for the upper endoscopy. During the endoscopy a motility tube will be placed through your mouth, so that the end of the tube reaches the stomach and duodenum. Once the endoscopy is completed and the tube secured in place with tape, you will be moved to a different room where, the antroduodenal motility tube will be attached to a computer to measure contractions in your stomach and small intestine.
Part Two: Your baseline contractions will be recorded for three (3) hours. After the three (3) hours, the nurse will give you medication to stimulate muscle contractions in your stomach, then half an hour after that, the nurse will give you medication(s) to stimulate your duodenum. The response to these medications will determine proper treatment for you.
