Objectives For patients with lung cancer, surgical resection remains the best curative option and is associated with the longest disease-free survival. We present our institutional outcomes treating pulmonary malignancy with robotic lobectomy over the course of 1 year. Methods A retrospective review was conducted on patients who underwent robotic pulmonary lobectomy for malignancy at a single institution in 2018. Results Over the course of 1 year, 166 patients underwent robotic lobectomy for pulmonary neoplasm. The mean age of the patients was 75 years; 73% were current or prior smokers and 52% of the patients were male. The mean body mass index was 28 kg/m2. Conversion to open thoracotomy occurred in 7% of patients. The mean total hospital length of stay (LOS) was 3 days. Histopathological examination revealed a mean tumour size of 2.7 cm with 11 lymph nodes harvested. Left-sided tumours had a significantly higher number of lymph nodes harvested when compared to right-sided tumours (11.6 vs. 9.8, P = 0.01), despite sampling the recommended minimum of three N2 stations. The most common pathology was adenocarcinoma (65%), followed by squamous cell carcinoma (17%) The 30-day operative mortality was 0.6%. Conclusions Robotic video-assisted thoracoscopic surgery is a safe, feasible and oncologically adequate procedure for lung malignancies. Comparison of our outcomes to previously reported national averages suggests a similar hospital LOS, lymph node harvest, conversion rate to open thoracotomy and 30-day mortality rate. We acknowledge the limitations of this non-randomised, retrospective study. Future research on robotic lobectomies is encouraged.
