Endoscopic exploration of the esophagus through the nostrils: Purpose, dangers, preparations, and details
Transnasal Esophagoscopy (TNE): A Minimally Invasive Diagnostic Test
Transnasal esophagoscopy (TNE) is a test used by doctors to examine the esophagus and stomach, offering a less invasive alternative to traditional endoscopies. This procedure, which does not require any special preparations beyond ensuring the stomach is empty for 4 hours before the test, is often recommended for a variety of symptoms related to the esophagus and upper airway.
During the procedure, a numbing medication is sprayed inside the person's nose and throat, making the process more comfortable. The endoscope, which has a light and camera attached to its end, is then inserted into a nostril and guided down into the throat while the person swallows small sips of water. The doctor slowly moves the endoscope into the esophagus, looking for any atypical signs that may indicate issues such as gastroesophageal reflux disease, cancer, or other conditions.
TNE is well-tolerated by most people, and they can drive home and resume their regular activities after the test. However, some people may experience mild discomfort, which can be relieved with acetaminophen (Tylenol).
TNE is particularly useful for diagnosing conditions that cause symptoms such as difficulty swallowing (dysphagia), a feeling of a lump in the throat (globus sensation), throat burning, chronic cough, hoarseness, persistent heartburn or regurgitation, and other signs suggestive of laryngopharyngeal reflux (LPR) or structural abnormalities in the esophagus and proximal airway.
In children, TNE may be recommended for symptoms including chronic cough, hoarseness, noisy breathing (stridor), feeding difficulties, apnea, and other airway-related problems.
By providing direct visualization of the esophagus, TNE allows doctors to diagnose atypical formations or changes in the stomach or esophagus. If atypical features are found, the healthcare professional may collect a tissue sample or perform other procedures to clear any blockages in the GI tract.
In conclusion, TNE is a valuable diagnostic tool for evaluating symptoms related to the esophagus and upper airway, particularly when less invasive means are insufficient. It offers a minimally invasive alternative to traditional endoscopies, with the added benefit of not requiring general anesthesia. If you are experiencing symptoms suggestive of esophageal or laryngopharyngeal pathology, speak with your doctor about whether TNE could be a suitable diagnostic option for you.
This minimally invasive diagnostic test, Transnasal Esophagoscopy (TNE), is often used in medical-conditions that exhibit symptoms such as difficulty swallowing (dysphagia) or a feeling of a lump in the throat (globus sensation), and can also help diagnose persistent heartburn or regurgitation, throat burning, chronic cough, hoarseness, and other signs suggesting laryngopharyngeal reflux (LPR) or structural abnormalities in the esophagus and proximal airway. In the realm of health-and-wellness, TNE provides a valuable condition assessment, particularly when less invasive means are insufficient, offering a less invasive alternative to traditional endoscopies with the added benefit of not requiring general anesthesia.
