Effects of manipulations to detect sliding hiatal hernia in dogs with brachycephalic airway obstructive syndrome

Abstract

Manipulations aimed at increasing the transdiaphragmatic pressure gradient during endoscopy in BAOS dogs allowed the detection of GEJ abnormalities and SHH that were not detected under standard conditions. Although MP allowed detection of SHH in more dogs than ETO, scores under MP did not correlate with digestive clinical signs. Therefore, ETO may be more accurate manipulation for the detection of GEJ abnormalities in BAOS dogs.
