Endoscope-guided, transoral axial division of an entrapping epiglottic fold in fifteen standing horses.

Abstract

OBJECTIVES: To describe and evaluate the use of a transoral, endoscope-guided technique for transection of an entrapping epiglottic fold in sedated standing horses. STUDY DESIGN: Retrospective study. ANIMALS: Horses (n=16) with epiglottic fold entrapment (EFE). METHODS: Medical records (2005-2006) of 16 horses with EFE were reviewed to determine history, physical and endoscopic examination findings, postoperative complications, and outcome after axial division of EFE using a hooked bistoury, under an endoscopic-guided, transoral approach. RESULTS: EFE was confirmed by endoscopy. Axial division was successfully performed in 15 sedated, standing horses. One horse had to be anesthetized to complete the procedure. None of the horses made abnormal respiratory noise after surgery and all returned to their intended use. After surgery, 1 horse had a short, deformed epiglottis. CONCLUSIONS: EFE can be axially divided safely and effectively using an endoscope-guided, transoral approach, with the horse sedated and standing. CLINICAL RELEVANCE: Endoscopic-guided, transoral axial division of EFE in sedated standing horses is an alternative choice to performing this procedure under general anesthesia.
