Summary
Video-assisted thoracoscopy (VAT) for diaphragmatic plication in dogs resulted in less postoperative pain and faster recovery compared to thoracotomy. Both methods effectively restored ventilatory mechanics, with VAT showing improved outcomes.
Area of Science:
- Veterinary Surgery
- Thoracic Surgery
- Comparative Medicine
Background:
- Nonfunctional hemidiaphragm impairs ventilatory mechanics.
- Diaphragmatic plication aims to restore function.
- Two surgical techniques exist: video-assisted thoracoscopy (VAT) and thoracotomy.
Purpose of the Study:
- Compare VAT and thoracotomy for diaphragmatic plication in dogs.
- Evaluate post-operative outcomes including pain, recovery, and respiratory function.
Main Methods:
- Twenty dogs with induced diaphragmatic paralysis underwent VAT (Group A) or thoracotomy (Group B).
- Respiratory frequency (f) and lung area (LA) were measured pre- and post-procedure.
- Surgical time, recovery metrics, pain, and complications were recorded.
Main Results:
- Group A (VAT) experienced significantly less pain, earlier fluid intake, and quicker ambulation.
- Post-operative lung area (LA) was comparable between groups.
- Group A showed a significant decrease in respiratory frequency (f) post-procedure.
Conclusions:
- Both VAT and thoracotomy are effective for diaphragmatic plication in dogs.
- VAT offers advantages of reduced pain and faster recovery.
- VAT is a safe and efficient surgical option for canine diaphragmatic plication.
