According to National Comprehensive Cancer Network guidelines concerning non–small cell lung cancer, robotic lobectomy is considered an advisable oncologic procedure for patients with lung cancer, with no anatomic or surgical contraindications. At present, da Vinci is the only available robotic system (Intuitive Surgical, Inc., Sunnyvale, CA), with 2 platforms (da Vinci SI and da Vinci XI) requiring different port-mapping and cart positioning. Robotic left lower lobectomy can be considered one of the most technically simple of all lobectomies. We describe our endoscopic technique, with 4 surgical ports, using CO2 insufflation.
