Zusammenfassung: | Objective
To describe complications and outcomes of dogs undergoing thoracoscopic‐assisted (TA) lung lobectomy.
Study design
Multi‐institutional, retrospective study.
Animals
Client‐owned dogs (n = 30).
Methods
Medical records of dogs that underwent TA lung lobectomy were reviewed. Signalment, bodyweight, clinical signs, imaging findings, surgical variables, complications, and short‐term/long‐term outcome were assessed. Thoracoscopic‐assisted lung lobectomy was performed with a mini‐thoracotomy.
Results
Twelve intraoperative complications were recorded in 11 dogs, 6 requiring conversion to open thoracotomy. Reasons for conversion were reported in 5/6 dogs and included adhesions (2), difficultly manipulating the lesion through the mini‐thoracotomy (2), and acute oxygen desaturation (1). One lung ventilation was successful in 4 of the 7 dogs in which this was attempted. A linear stapling device (DST series Medtronic, Minneapolis, Minnesota) was used for lung lobe ligation in 14 dogs. Twenty‐three dogs underwent surgery for a neoplastic lesion, with 19 of these being carcinoma. The median lesion size was 4.3 cm (range 1‐10 cm); margins were clean, except in 1 dog. Complications were documented in 8 dogs prior to discharge, 5 of these being classified as mild. Twenty‐nine dogs were discharged at a median of 47 h postoperatively (range 24‐120 h). Death was reported in 9 dogs, with a median survival time of 168 days (range 70‐868 days).
Conclusion
Thoracoscopic‐assisted lung lobectomy was achieved with few major complications in the population reported here. Dogs were able to be discharged from hospital quickly, with most surviving beyond the follow‐up period.
Clinical significance
Thoracoscopic‐assisted lung lobectomy may be considered to facilitate the excision of larger pulmonary lesions or to treat smaller dogs, in which a thoracoscopic excision may be technically more challenging. |
