Instructions for Heartburn/Hiatal Hernia Work Up

Dr. Leggett and his staff realize that meeting under this set of circumstances isn't exactly ideal, but we're here to help you get through the series of testing required as smoothly and uneventfully as possible. We hope you find the following information helpful and answer any questions you might have.

There are three (3) tests required to evaluate each person before determining the correct treatment plan. The three tests include: Esophogram/Upper GI Study, Gastroscopy, and Manometry. Additional testing may be required on an individual basis.

An Esophogram/Upper GI Study is a x-ray test where pictures are taken of the esophagus and stomach to determine the presence of a hiatal hernia, reflux, and to rule out other lesions in the esophagus or stomach. In addition, it provides useful anatomical information and is a road map if surgery is indicated. You may be asked to pick up the films and bring them to the office for Dr. Leggett to review.

A Gstroscope is an endoscopic procedure where a flexible tube with a light is used to examine the inside of the esophagus and stomach. It provides an opportunity to view, take pictures, and obtain tissue samples of the lining (biopsy) of the esophagus and stomach, which will be sent to the lab for analysis.

An Esophageal Manometry is a test to check the motility of the esophagus to see if it is doing its job. It also includes testing the lower esophageal sphincter for pressures and if it's relaxing and closing as it should. This procedure is done by introducing a small, soft catheter into the nose, down the stomach and pulling this catheter a little at a time until we are in the sphincter then we give swallows of water to make the sphincter open and close. The catheter is then pulled to the lower and upper esophageal body and more swallows of water are given. The procedure is also recorded in a computer.


Nothing to eat or drink the night before your test or at least 4 hours prior to the procedure.

These are the medicines that need to be stopped at lest 72 hours prior to the procedure but his needs approval from your doctor: Propulsid, Procardia, Calan, Reglan, Coumadin or any blood thinner.
