Transnasal endoscopy (TNE) is a special test (commonly called a “scope”) that lets the doctor look at the lining of your child’s gastrointestinal (GI) tract. An endoscope (in-doe-scope) is a long, thin, hollow tube with a special camera and light at the end. The doctor uses this camera to look at the GI tract. The parts of the GI tract your doctor can look at with the TNE scope are the:
- Esophagus (e-sof-a gus)
During the TNE, your doctor may take biopsies, or small pieces of tissue from the esophagus. Most children do not feel anything when the biopsies as taken, a few feel a mild 'tug,' and very rarely some feel a slight pinch.
TNE looks at the upper part of the GI tract (esophagus, stomach) to monitor the activity of a chronic condition. Sometimes the doctor may need to look at the lower part of the GI tract (large intestine and lower part of the small intestine) which would require a traditional gastrointestinal endoscopy.
TNE does not require general anesthesia (being put to sleep). Your child will have a numbing nose spray and throat medicine before the test. No other medicines are needed.
Location of Transnasal Endoscopy Test
7777 Yankee Road, Liberty Township
Third Floor, GI clinic Hospital Stay
Your child’s total time at the hospital is about one to one and a half hours. This includes the time before and after the TNE scope. Unlike traditional GI endoscopy, TNE does not use anesthesia.
Transnasal endoscopy is a safe procedure. Few children have unexpected or serious complications.
After the TNE scope, children may have:
- Mild sore nose and throat
- Burping and sense of fullness
The risks of the TNE scope include:
- Bleeding from the biopsy sites
The risk of a complication is very small. Your healthcare team will review these risks in more detail during your clinic visit.
