PURPOSE: To verify whether pediculated diaphragmatic flaps were suitable to correct iatrogenic wounds in dog's esophagus injuries. METHODS: Seven dogs were submitted to resection of a segment of the esophagical wall, which was then corrected by suturing a pediculated diaphragm flap. Endoscopic evaluation of the esophagical wall was done forty days after the surgical procedure. RESULTS: Three animals died, one due to implant ischemia, caused by strangulation of the phrenic artery; other due to wound infection; and the last, due to mediastinitis. Scar retraction was observed, however, there was no stenosis, allowing the passage of a 9,8 mm probe with no difficulty. The limits between the implants and the native esophagus were indistinguishable, and the implant was covered by esophageal mucosa. CONCLUSION: The diaphragmatic flaps are suitable on the restoring of continuity in dog's thoracic esophagus.
