Plain-English summary
A group of 61 dogs with lung masses underwent a minimally invasive surgery called thoracoscopic lung lobectomy to remove the tumors. All the dogs survived the surgery, and most were still alive a month later. The study found that larger tumors and certain lymph node issues seen on scans could make the surgery more complicated, but overall, the dogs had a good chance of recovery and long-term survival after the procedure. This type of surgery seems to be a promising option for dogs with lung tumors.

Abstract
OBJECTIVE: To report and evaluate risk factors for conversion and perioperative and long-term outcomes in dogs undergoing thoracoscopic lung lobectomy for resection of lung masses. ANIMALS: 61 client-owned dogs. METHODS: This retrospective cohort study (June 11, 2008, to February 14, 2020) of data collected from medical records included signalment, results of diagnostic imaging, surgical technique, surgical and anesthesia time, mass location and size, hospitalization time, histopathologic findings, and long-term outcome. Follow-up was obtained from medical records and telephone contact with owners or referring veterinarians. RESULTS: Histopathology results were available for 60 of 61 tumors. Fifty-seven (95%) were considered primary lung tumors, of which 46 (81%) were carcinomas. Clean surgical margins were achieved in 46 of 52 (88%) dogs. Conversion from thoracoscopy to thoracoscopic-assisted or open surgery occurred in 16 of 61 (26%) dogs. Larger tumor diameter (≥ 5 cm) and lymphadenopathy detected by preoperative CT scan were significantly associated with increased risk of conversion. There was no association between conversion and patient weight, body condition score, and tumor location. All 61 dogs survived to discharge, and 56 of 57 were alive 1 month postoperatively. Median overall survival time was 311 days (95% CI, 224 to 570 days). Tracheobronchial lymphadenopathy on preoperative CT scans was associated with shorter postoperative survival (P < .001). Patient age, tumor diameter, adjuvant chemotherapy following surgery, and incomplete margins were not associated with survival time. CLINICAL RELEVANCE: Dogs had high survival to discharge and good long-term prognosis following thoracoscopic lung lobectomy. However, larger tumor size and tracheobronchial lymphadenopathy may increase the likelihood of conversion.
