Insights
A cat with regurgitation was diagnosed with omental herniation through the esophageal hiatus. Surgical repair of the hiatus successfully resolved the condition, allowing the cat to recover fully.
Area of Science:
- Veterinary Surgery
- Small Animal Medicine
- Surgical Pathology
Background:
- Regurgitation in cats can indicate various gastrointestinal or thoracic abnormalities.
- Omental herniation into the posterior mediastinum is a rare condition that can cause esophageal compression.
Observation:
- A four-year-old male cat presented with regurgitation.
- Radiography revealed a posterior mediastinal mass and elevated esophagus, suggestive of herniation.
- Exploratory thoracotomy confirmed omental herniation through the esophageal hiatus.
Findings:
- The omental herniation was significant, necessitating a combined thoracotomy and celiotomy for reduction.
- The esophageal hiatus measured approximately 1 cm in diameter, without observed adhesions.
- Surgical closure of the esophageal hiatus using continuous sutures successfully reduced its diameter.
Implications:
- This case highlights the importance of considering omental herniation in cats with regurgitation and mediastinal masses.
- Surgical management, including hiatus repair, can be effective for treating omental herniation.
- Successful outcomes underscore the feasibility of surgical correction for this rare condition in felines.
Abstract:
A four-year-old male cat was presented with regurgitation. Thoracic radiography and contrast radiogram showed a large oval mass and elevated esophagus. Exploratory thoracotomy showed omental herniation into the posterior mediastium through the esophageal hiatus. Because the mass of the omental herniation was so large, celiotomy through a paracostal incision was combined in order to return the omentum to its normal position. The diameter of the esophageal hiatus was approximately 1 cm but no fibrous adhesion was observed around the hiatus. Continuous 1-0 surgical sutures on the hiatus reduced the diameter of the hiatus. The cat made a successful postoperative recovery without complications.
