Abstract

Abstract: Objective: Static endoscopic evaluation of swallowing (SEES) is an instrumental evaluation developed for in‐office identification of patients who may benefit from a modified barium swallow study (MBSS). We aim to determine the predictive value of SEES for evaluating dysphagia. Methods: A retrospective case series was performed on adults evaluated for dysphagia using SEES followed by MBSS at a single tertiary care center. Studies were evaluated by two blinded expert raters. Results: Fifty‐eight patients were included. Thin liquid penetration on SEES had a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 0.86 (95% CI 0.70‐0.95), 0.63 (95% CI 0.24‐0.91), 0.91 (95% CI 0.76‐0.98), and 0.5 (0.19‐0.81), respectively, for predicting thin liquid penetration on MBSS, and 1.0 (95% CI 0.59‐1.0), 0.29 (95% CI 0.15‐0.47), 0.23 (95% CI 0.10‐0.41), and 1.0 (95% CI 0.69‐1.0) for predicting thin liquid aspiration on MBSS. Thin liquid aspiration on SEES had a sensitivity, specificity, PPV, and NPV of 0.67 (95% CI 0.09‐0.99), 0.85 (95% CI 0.66‐0.96), 0.33 (95% CI 0.04‐0.78), and 0.96 (95% CI 0.79‐1.0), respectively, for predicting thin liquid aspiration on MBSS. Conclusions: SEES may be used as an objective in‐office test to screen for aspiration and penetration. Thin liquid penetration on SEES is moderately sensitive for predicting penetration on MBSS. Absence of thin liquid penetration or aspiration on SEES has a high NPV for excluding aspiration on MBSS. Abnormalities on SEES or the need to view the entire swallowing mechanism should prompt an MBSS for a more complete evaluation of dysphagia.
