Evaluation of urine sucrose concentration for detection of gastric ulcers in horses.

Objective: To evaluate the use of sucrose permeability testing to detect ulcers in the gastric squamous mucosa of horses.

Animals: 13 adult horses ranging from 5 to 19 years of age.

Procedure: Following induction of gastric ulcers by intermittent feed deprivation, horses underwent sucrose permeability testing (administration of sucrose by nasogastric intubation followed by collection of urine at 2 and 4 hours after intubation) and gastric endoscopy.
