You have been scheduled for a procedure on your esophagus. The esophagus is the tube that runs from your mouth to your stomach and transports food when you eat. This organ may need to be visualized for a variety of reasons, the most common being heartburn or laryngopharyngeal reflux symptoms without response to antacid medication or dietary changes, chronic cough without an identified cause, or the sensation of having a lump in the throat (globus pharyngeus).
This procedure permits the otolaryngologist to obtain important information about the esophagus and throat in a fast, effective, and safe way, using your nose as a passageway into your throat and esophagus.
What is involved in a transnasal esophagoscopy?
This procedure usually takes less than 30 minutes and is done with sedation. During a transnasal esophagoscopy, a high-tech camera in the endoscope enters the nares and passes into the throat and allows us to evaluate patients with problems of swallowing or heartburn. Video is recorded to review with the patient at the end of the visit.
Patients receive topical anesthesia (lidocaine) and decongestant, which are applied to one of the nasal passages. The lidocaine should pass down the throat and into the esophagus and be swallowed to help numb the throat and esophagus.
What should I expect after surgery?
After you wake up, your throat may feel numb for about an hour after your procedure. You should not eat or drink for one hour after the procedure to avoid any food going down the “wrong pipe” (aspiration). Your nose may also feel sore after the procedure. If you do feel nasal discomfort, Tylenol may relieve any soreness.
Possible risks involved with the sedation involved during this procedure are rare.
