Thoracoscopic treatment of bullous emphysema in 3 dogs.

OBJECTIVE

To report thorascopic partial lobectomy for treatment of bullous emphysema in dogs.

STUDY DESIGN

Prospective clinical study.

ANIMALS

Three dogs with spontaneous pneumothorax.

METHODS

Thoracoscopy without pulmonary exclusion was used to identify bulla. The thorascope was introduced into the thorax lateral to the xyphoid process, and instrument portals were made at different levels along the thoracic wall between the third and tenth intercostal spaces. The thorascope was passed through the mediastinum to view the opposite pleural cavity. After identification of bullae, the affected lung was excised using an endoscopic stapler, and the incision line was checked for air leakage. Thoracic drains were used for air aspiration for 2 days after surgery.

RESULTS

Bullae were confirmed histologically as emphysematous lesions. Lung inflation did not interfere with identification of bullae or with surgery. All dogs had full recovery without recurrence for 18 to 29 months after surgery.

CONCLUSIONS

Identification and ablation of bulla can be performed thoracoscopically without pulmonary exclusion in dogs.

CLINICAL RELEVANCE

Thoracoscopy offers several advantages compared with thoracotomy for treatment and diagnosis of idiopathic pneumothorax, including ease of identification of bullae and reduced postoperative pain and morbidity.
