Esophagomyotomy and esophagopexy to create a diverticulum for treatment of chronic esophageal stricture in 2 horses.

We report use of esophagomyotomy and esophagopexy to create a diverticulum for relief of chronic type I esophageal stricture in 2 horses. After esophagomyotomy, the mucosa was dissected free from the muscularis for approximately 180 degrees around the myotomy. Then, the tunica muscularis of esophagus was sutured to the sternocephalicus muscle ventrally and the periesophageal tissues dorsally to create a diverticulum without disruption of the esophageal mucosa. Clinical signs of esophageal stricture were relieved, and the horses were fed normal diets without further esophageal obstruction.
