Esophagocardioplasty with gastric pouch. An experimental study in dogs.

In 18 dogs esophagocardioplasty was performed through an abdominal incision with a gastric patch taken from the minor curvature of the stomach. In four dogs the mucosa was removed from the gastric patch and in six dogs a Nissen fundoplication was done. The dogs were observed for 1 year. All dogs showed macroscopic and microscopic signs of esophagitis with ulcers; three had esophageal perforation and two dogs had esophageal stenosis. We found that gastric patches with peptic acid secretory mucosa in dogs cause grave esophageal lesions.
