Gastro‐oesophageal resection and anastomosis for an oesophageal leiomyoma in a dog

An 11-year-old female spayed golden retriever was presented for a second opinion regarding a recently diagnosed distal oesophageal mass. The dog had a history of chronic post-prandial regurgitation. Physical examination and laboratory work yielded no significant findings. Thoracic radiographs revealed no significant findings other than equivocal cardiomegaly. A fluoroscopic barium swallow study and computed tomography scans of the chest and abdomen were performed, revealing an approximately 2.5 cm mass at the level of the lower oesophageal sphincter. A gastro-oesophageal resection and anastomosis was performed and histopathology of the mass was consistent with leiomyoma, excised with complete margins. The dog recovered uneventfully and was discharged from the hospital 3 days after surgery. The dog was doing well 5 months after surgery, with an acceptable quality of life and mild, intermittent regurgitation episodes.
