Introduction:

The aim of this study was to evaluate the current indications for and clinical factors influencing the use of transnasal esophagoscopy (TNE).

Methods:

An online survey was sent to American Broncho-Esophagological Association members, including questions on demographics, indications, and factors influencing the use of TNE.

Results:

Sixty of 251 members (24%) completed the survey. Ninety-three percent of respondents reported academic practices, while 98% practice in medium to large urban settings. Thirty-five (58%) completed laryngology fellowships. Mean monthly TNE procedure count was 7.15 (range, <1-35). The most common indications were dysphagia (82%), biopsy (50%), and laryngopharyngeal reflux (47%). Chronic cough, head and neck cancer screening, gastroesophageal reflux (GER), and tracheoesophageal puncture were also commonly reported indications (44% each). For laryngopharyngeal reflux and GER, most respondents perform TNE for recalcitrant disease following a medical trial of at least 3 months. Long-standing GER symptoms, documentation of GER on pH and impedance testing, and abnormal findings on previous esophagoscopy lead to greater TNE use. Specific dysphagia indications included abnormal esophagographic findings (70%), history or examination localizing to the esophagus (60%), solid dysphagia only (53%), and solid and/or liquid dysphagia (40%). The primary sites most likely to prompt TNE use for head and neck cancer surveillance were the esophagus (92.3%) and hypopharynx (84.6%). Balloon dilation was the most common indication for which respondents do not currently perform TNE but would like to (n = 8).

Conclusions:

TNE indications have not been well established. According to respondents from the American Broncho-Esophagological Association, TNE is most commonly used for dysphagia and laryngopharyngeal reflux and slightly less so for GER and head and neck cancer screening and surveillance. Several clinical indicators were identified that influence the decision to perform TNE.
