Summary

Unsedated transnasal esophago-gastro-duodenoscopy (UT-EGD) has gained wide popularity and is one of the most frequently performed diagnostic procedures in Japan and Europe. The technique of using a cotton pledget soaked with lignocaine and decongestant is quite effective but does cause some discomfort during application of anesthetic agent to the nasal cavity. Hence, an effective method to deliver anesthetic agent, using a minimal dose of drugs, and at the same time maintain a good field of vision during endoscopy are all very important.

Using a cotton-tippled applicator to deliver a soaked gauze strip may cause kinking of it around the nasal vestibule or just in the anterior end of a turbinate. Endoscopic guidance to deliver a gauze strip can confirm delivering it to at least the posterior end of a turbinate. We hypothesize that a simple endoscopic-guided gauze pledgetting method is more tolerable than the "blind" cotton-tippled applicator method to deliver a gauze strip for anesthetizing the nasal cavity.

  • Side Effects of Transnasal Endoscopy
  • Patient's Tolerance to Transnasal Endoscopy

Interventions

PROCEDURE

Endoscopic-guided gauze pledgetting

By using a transnasal endoscope as a guide and a biopsy forceps, a gauze strip soaked with decongestant and anesthesia will be delivered to a selected nasal meatus chosen by anterior rhinoscopy.

PROCEDURE

Cotton-tipped applicator gauze pledgetting

In contrast to the endoscopic-guided, forceps-delivering method, a gauze strip is delivered to a selected meatus by a cotton-tipped applicator.
