Prospective multi-institutional transnasal esophagoscopy: Predictors of a change in management.

To evaluate clinical indications and endoscopic findings for patients undergoing transnasal esophagoscopy (TNE).

Prospective, multi-institutional, observational cohort study at four tertiary centers.

Demographics, reflux finding score, reflux symptom index, Eating Assessment Tool (EAT-10) scores, clinical indications, and endoscopic findings were compared among patients whose TNE findings resulted in a changes in management (FCIM), defined as a referral, new medication, or surgery recommendation.

Of the 329 patients who were enrolled nine (3%) were unable to complete the exam. In an adjusted regression model, male gender and elevated body mass index were significantly predictive of a positive TNE (P =.013-.045); 51% (n = 162/319) had TNE with FCIM. Common FCIM were esophageal stricture (7.5%), irregular Z-line (27.4%), reflux esophagitis (12.8%), and infectious esophagitis (6.3%) (P <.001-.010). Overall, the average EAT-10 was higher for patients with FCIM (9.7 vs. 5.4) than in those without it (P =.014). Patients with a history of head and neck cancer (HNCA) had FCIM 64% of the time, which rose to 81% if they had both HNCA and dysphagia.

In treatment-seeking patients TNE is predictive of a change in management in males and obese patients. In patients with HNCA and dysphagia, TNE is likely to yield findings that cause a change in management.
