Hi Lucy,
My husband is a gastroenterologist and with his aid I will explain these 2 test to you.
pH capsule monitoring study: A small device about 3/4 inch long is attached to the wall of the esophagus. It is inserted under endoscopic guidance. You will be sedated and the endoscope will be inserted in your mouth and guided into the esophagus. The capsule will send electronic messages to a recording device worn in a belt. You will wear this belt for 24 hours. The next day the readings from the recording device will be read by your gastroenterologist. The capsule device will detach from the esophagus wall, pass through your digestive tract and be eliminated in your stool.
Esophageal manometry: A small tube about the width of a strain of thick spaghetti is inserted through your nose and passed into the stomach. There is no sedation for this study. The tube measures the pressure in different portions of the esophagus. It can measure the muscle function within the esophagus. The tube is slowly withdrawn and as it is removed you will be asked to take small amounts of water. This test takes about 20 minutes.
