Transnasal Oesophagoscopy is a method of examining your pharynx (throat), larynx (voicebox), upper oesophageal sphincter (valve between the throat and oesophagus), oesophagus (food pipe to the stomach), and stomach.
A flexible tube with a camera in the tip is passed through the nose into the throat and then swallowed into the oesophagus. This allows visualisation of the lining of these organs, biopsies if necessary, stretching of narrowed regions (strictures), observation of hiatal hernia or signs of reflux damage (oesophagitis, ulcers, strictures or Barrett's metaplasia). Additional therapeutic procedures may be combined with transnasal oesophagoscopy including laser treatment or balloon dilation.
This procedure may be done without sedation, in the office, and takes around 5-7 minutes. You can eat and drink immediately following the procedure, but we recommend not eating or drinking for four hours prior to undertaking this procedure.
