title: The Practicability of Transnasal Esophagoscopy and the Evaluation of Patient's Perception: A Prospective Study.
abstract: OBJECTIVE
  Transnasal esophagoscopy (TNE) is a relatively new diagnostic procedure in the evaluation of patients with globus sensation and dysphagia. Enabling doctors to examine all of the upper aerodigestive system without the need for sedation, this technique is becoming more popular among otolaryngology specialists. The aim of this study is to evaluate the practicability of TNE and tolerability of patients to the test.
  
  
  METHODS
  The study group consisted of 314 patients who were admitted to the swallowing center of a tertiary medical institution with the symptoms of dysphagia and globus sensation. In addition to other diagnostic procedures, patients were informed of the TNE and the necessary consents were obtained. Before the examination, patients were asked to foresee the level of discomfort they would presumably feel, according to the information they had. After the TNE, patients were asked to score the real level of discomfort they experienced during the test. A visual analog scale was used to note the levels. The duration of the tests and any complications were also noted.
  
  
  RESULTS
  We could not perform TNE in 12 of the 314 patients due to nasal obstruction, intractable retching and vasovagal syncope (7, 4, and 1 patients, respectively). The average discomfort score foreseen before the test was 4.7±1.4 (mean±standard deviation). The post-procedure discomfort score was 1.6±1.1, and the difference was statistically significant (P<0.001). The average time to perform the TNE was 5 minutes (range, 3 to 13 minutes). Except for minor epistaxis in 7 patients (2%), no complications occurred.
  
  
  CONCLUSIONS
  According to our results, TNE is an easy and well-tolerated procedure, it may be logical to tell the patient that the procedure will be less annoying and irritating than they assume. It is also a time saving procedure with low complication rates.
