Daisy

• Patient:
  Daisy, 8 month old spayed female mixed-breed dog.



• Presenting complaint:
  Regurgitation several days each week. The signs are typical of esophageal disease. The dog was smaller than its littermates, but did have good body condition.



• Diagnostic studies before endoscopy:
  Thoracic radiograph revealed a dilated esophagus with a narrowing at the fifth thoracic space.



• Endoscopic procedure:
  Thoracoscopy using 4 small trocar openings was used to evaluate and identify a stricture about the esophagus at the level of the fifth space. A fibrous band (persistent right aortic arch) was identified and resected using a ligasure forceps. The esophagus was dilated by passing an esophageal tube.



• Benefits of using endoscopy:
  This minimally invasive surgery avoided an open thoracoctomy. A chest tube was placed. Daisy did very well after surgery and began to gain weight.
