This test helps determine the strength of the muscles in the esophagus. It is useful in evaluating gastroesophageal reflux and swallowing abnormalities. A small tube is guided into the nostril, then passed into the throat and finally into the esophagus. The pressure the esophageal muscles produce at rest is then measured.
Esophageal pH monitoring
An esophageal pH monitor measures the acidity inside of the esophagus. It is helpful in evaluating gastroesophageal reflux disease (GERD). A thin plastic tube is placed into a nostril, guided down the throat and then into the esophagus. The tube stops just above the lower esophageal sphincter, which is at the connection between the esophagus and the stomach. At the end of the tube inside the esophagus is a sensor that measures pH, or acidity. The other end of the tube outside the body is connected to a monitor that records the pH levels for a 12 to 24 hour period. Normal activity is encouraged during the study, and a diary is kept of symptoms experienced or activity that might be suspicious for reflux, such as gagging or coughing. The pH readings are evaluated and compared to the child's activity for that time period.
BRAVOTM PH Monitoring system:
This test allows for the doctor to measure the amount and frequency of PH levels in the esophagus. A miniature PH capsule (the size of a gelcap) is attached to your child's esophagus during endoscopy. The capsule transmits information to a pager-sized receiver that is worn on a belt or waistband. A diary is given to write down the times there are reflux symptoms, when eating or lying down. After the test is complete (48 hours) the diary and Bravo receiver are returned and the information entered into the computer. The doctor will go over the report with you.
EGD (esophagogastroduodenoscopy) (also called upper endoscopy)
EGD (upper endoscopy) is a procedure that allows the physician to look at the inside of the esophagus, stomach, and duodenum. A thin, flexible, lighted tube called an endoscope is guided into the mouth and throat, then into the esophagus, stomach, and duodenum. The endoscope allows the physician to view the inside of this area of the body, as well as to insert instruments through a scope for the removal of a sample of tissue for biopsy (if necessary).
Capsule Endoscopy enables your doctor to examine the three portions (duodenum, jejunum, ileum) of your small intestine. Your doctor will use a vitamin-pill sized video capsule as an endoscope, which has its own camera and light source. While the capsule travels through your body, images are sent to data recorder you wear on your waist belt for approximately 8 hours.
