Abstract

Background: Accurate tracheoesophageal prosthesis (TEP) size is essential for optimal functioning. Current sizing techniques do not afford direct visualization. The clinical utility of direct visualization with unsedated transnasal esophagoscopy (TNE) to improve TEP sizing accuracy has not been established. Aims/Objectives: The purpose of this investigation was to determine if endoscopic visualization with TNE during TEP fitting improves sizing accuracy. Material and Methods: Participants undergoing secondary TEP placement had their TEP sized without visualization and with visualization during TNE. The effect of endoscopic visualization on TEP sizing was assessed. Results: The mean age (SD) of the cohort (N = 15) was 61.20 (±10.19) years. The percent disagreement between non-visualized and endoscopic-visualized puncture tract measurement was 60%. The mean difference in puncture tract length with visualization compared to without visualization was 1.75 mm (±1.91). Discordance between non-visualized and endoscopic-visualized puncture tract length was worse for persons with a history of radiation (66.7%) than without radiation (33.3%) (p <.05). The overall test agreement between endoscopic and non-endoscopic sizing techniques was moderate (Cohen’s kappa coefficient = 0.254; (p <.05). Conclusion and Significance: The percent disagreement between non-visualized and endoscopic-visualized TEP sizing is high (60%). The data suggest that endoscopic visualization with TNE improves sizing accuracy during TEP placement.
