Transnasal flexible esophagoscopy (TNE): an evaluation of the patient’s experience and time management

The aim of this study was to evaluate patient’s experience when performing transnasal flexible endoscopy using EndoSheath Technology without sedation in an ENT outpatient department. Patients were seen at the laryngological clinic of the Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Heidelberg, presenting with complaints of reflux like throat cleaning, persistent cough, globus sensation, heartburn, or voice problems. First, we performed stroboscopy. In cases where physical examination findings revealed the presence of LPR, we performed a transnasal flexible esophagoscopy (TNE) using sterile EndoSheath Technology under local anesthesia. 55 patients were investigated and completed a questionnaire on subjective discomfort that they felt during the procedure. The different steps of the examination were assessed separately. Complications were noted down by the surgeon. All patients underwent a complete examination of the upper aerodigestive tract. The time needed for preparation, examination and cleaning measures was recorded as well. The average preparation time for each examination was 24 min. No complications were observed during the procedure. The procedure was well tolerated by all patients and was classified on average as “low-grade unpleasant”. In summary, TNE is a safe, quick and well-tolerated procedure that can be performed in a regular examination room under local anesthesia without sedation.
