OBJECTIVE: Preliminary study that describes unsedated, transnasal esophagos
copy (TNE) in an office setting.
STUDY DESIGN AND SETTING: TNE was prospectively performed on 14 consecutive
out-patients with dysphagia whose initial oropharyngeal dysphagia evaluati
on was insufficient to reveal the cause of their swallowing problem. TNE wa
s carried out without conscious sedation while the patients were sitting in
an examining chair. Ease of endoscope insertion, optical quality of images
, and examination findings were assessed. Heart rate before and after the p
rocedure and incidence of epistaxis and airway compromise was also determin
ed. Patients were asked to rate the level of discomfort of TNE on a validat
ed 10-point scale (1 representing none/well tolerated and 10 severe/poorly
tolerated).
RESULTS. All patients completed TNE with the esophagus readily intubated an
d esophageal mucosa clearly visualized. Findings included esophageal strict
ure, patulous upper esophageal sphincter, and Zenker's diverticulum. There
were no incidences of epistaxis or airway compromise and no significant cha
nges in heart rate. Overall tolerance of TNE was rated by the patients as 2
.0 (SD, 1.2).
CONCLUSIONS: TNE is well tolerated and can be safely performed in patients
with dysphagia in an office setting. TNE may have a role in the comprehensi
ve evaluation of the dysphagic patient in the office.
