Does robotic surgery reduce hospital stays for patients with early-stage NSCLC?
For early-stage non-small cell lung cancer (NSCLC), surgeons often use minimally invasive techniques. Robotic-assisted thoracoscopic surgery (RATS) is one option, and video-assisted thoracoscopic surgery (VATS) is another. A key question is whether robotic surgery leads to shorter hospital stays. Some studies suggest a modest benefit, while others find no difference.
What the research says
A 2026 meta-analysis of nine studies (19,805 patients) found that robotic segmentectomy (removing a small part of the lung) was linked to a shorter hospital stay by about 0.75 days compared to VATS 3. The same analysis also found that robotic surgery examined more lymph node stations, which may improve cancer staging 3. However, operative time, drainage duration, and complication rates were similar between the two approaches 3.
An earlier meta-analysis from 2019, focusing on lobectomy (removing a whole lobe), found no significant difference in hospital stay between RATS and VATS 6. That analysis did show a lower mortality rate with robotic surgery, but also a tendency toward longer surgery time 6. These conflicting results suggest the benefit on hospital stay may depend on the specific procedure and patient factors.
Other sources in this set do not directly address robotic surgery and hospital stay. They cover topics like targeted therapy for advanced NSCLC 12, radiation therapy 5, and imaging biomarkers 4. None of these provide evidence about robotic surgery for early-stage disease, so they are not relevant to this question.
What to ask your doctor
- What is your experience with robotic surgery for early-stage NSCLC, and how does it compare to VATS in terms of recovery time?
- Based on my specific tumor size and location, which surgical approach would you recommend?
- How long might I expect to stay in the hospital after robotic surgery versus VATS?
- Are there any additional costs or risks associated with robotic surgery that I should consider?
