A Moment I Will Never Forget

It was a Tuesday afternoon in the OT at Artemis Hospital. A 54-year-old school teacher from Faridabad had just been wheeled out of the operating room. Her daughter was waiting outside, hands clasped, eyes red. She had spent three nights on the internet reading about open chest surgery — the long scar, the broken ribs, the weeks of pain, the months away from her classroom. When I walked out and told her that her mother's lung tumour had been removed through four tiny incisions smaller than her thumbnail, and that she would likely go home in two days, she just stared at me. Then she burst into tears. Not from fear. From relief she had not dared to feel until that moment.

That day stayed with me. Because her fear was real. For decades, chest surgery meant a 20-centimetre cut between the ribs, a hospital stay that stretched into weeks, and a recovery that robbed patients of months of their lives. That story has now changed. And the technology that changed it is called the Da Vinci Robotic Surgical System.

In this article, I want to walk you through what robotic thoracic surgery actually is, how it works inside the operating room, why it is different from older methods, what it can and cannot do, and why this matters deeply if you or someone in your family is facing a chest-related illness.

Quick Definition: Robotic thoracic surgery uses a surgeon-controlled robotic system to perform chest procedures through small keyhole incisions, using a high-definition 3D camera and flexible robotic instruments.

 

What Is the Da Vinci System and How Does It Actually Work?

Let me clear one thing up first, because I hear this question every week from patients:

"Doctor, is the robot going to operate on me by itself?" The answer is absolutely no. The Da Vinci robot has zero autonomy. It does not make a single decision. Every movement it makes is a direct response to what my hands and feet are doing at a control console a few feet away. Think of it as the most advanced, precise extension of a surgeon's hands ever built.

The Da Vinci system has three main parts. The first is the patient cart, which holds four robotic arms positioned around the patient. The second is the vision cart, which houses the 3D camera and energy systems. The third is the surgeon console, where I sit and control everything.

The Technology That Makes the Difference

Here is what makes Da Vinci different from anything that came before it:

• 7 Degrees of Freedom (EndoWrist Technology): A standard laparoscopic tool moves in 4 directions. The Da Vinci's wrist-like instruments move in 7. Inside the tight, narrow spaces of the chest, this is not a small upgrade. It is the difference between threading a needle in a corridor and threading it in a cupboard.
• 3D High-Definition Vision at 10x Magnification: I see tissue in three dimensions at ten times its real size. Blood vessels, lymph nodes, and tumour margins that were previously invisible to the naked eye are clearly defined on my screen.
• Motion Scaling and Tremor Filtering: When my hands move two centimetres at the console, the instruments inside your chest may move only two millimetres. Natural hand tremors are filtered out completely. Precision is not just improved. It is transformed.
• Ergonomic Surgeon Console: Unlike open surgery, where a surgeon stands bent over a patient for hours, I sit at the console in a controlled position. This matters because surgeon fatigue directly affects performance. A surgeon who is not tired makes better decisions.

According to Intuitive Surgical, more than 14 million procedures have been performed globally using Da Vinci systems. Over 38,000 peer-reviewed research papers have studied its outcomes. This is not an experimental technology. It is the most researched surgical robot in the history of medicine.

 

Why the Chest Is the Ideal Space for Robotic Surgery

Here is something that most articles about robotic surgery completely skip over, and I find it genuinely important.

The chest cavity is a naturally rigid, stable space. Unlike the abdomen, which is soft and can shift, the thoracic cage holds its shape. This creates consistent, predictable working space for the robotic arms. The narrow passages between lung lobes, blood vessels, airways, and lymph nodes are exactly where 7-degree wrist instruments perform at their best. Rigid laparoscopic tools struggle here. Robotic instruments do not.

Research published in leading thoracic surgery journals notes: 'The rigid anatomy of the chest appears to be an ideal condition for robotic-assisted surgery, enabling access to structures that are difficult or impossible to reach with standard video-assisted methods.' (Annals of Thoracic Surgery, 2022)

This is why robotic thoracic surgery has grown so rapidly. In 2009, robotic lobectomy represented less than 1% of all lobectomies performed in the United States. By 2020, that figure had risen to over 15% and continues to grow. The chest is where robotics deliver their highest value.

 

Conditions We Treat Using Robotic Thoracic Surgery in Gurgaon

At our centre at Artemis Hospital, we use Da Vinci robotic surgery to treat a wide range of thoracic conditions. Patients travel from across India and abroad for these procedures. Many come after being told elsewhere that their surgery would require a large open incision.

• Lung Cancer (all stages where surgery is an option): Robotic lobectomy (removal of a lung lobe), segmentectomy (removal of a precise portion of the lung), and wedge resection. For those exploring stage 4 lung cancer treatment in Gurgaon, robotic surgery can be part of a combined treatment plan alongside immunotherapy and targeted therapy.
• Esophageal Cancer: Robotic-assisted esophagectomy with ICG fluorescence imaging to check blood supply to the reconstructed food pipe in real time, reducing the risk of serious complications.
• Thymoma and Thymic Tumours: Robotic thymectomy is now widely considered superior to all other approaches for thymic surgery. The precision and vision robotic systems offer in the anterior mediastinum is unmatched.
• Mediastinal Masses: Tumours in the space between the lungs, in both the front (anterior) and back (posterior) mediastinum.
• Empyema and Bronchopleural Fistula: Robotic decortication and repair of abnormal passages in the lungs.
• Tracheal Conditions, Chest Wall Tumours, and Bullous Lung Disease.

Whether you are looking for an experienced oncologist in Gurgaon or seeking thoracic surgery in Delhi NCR for a second opinion, the range of robotic procedures available at our centre is comprehensive.

 

Robotic vs. VATS vs. Open Surgery: The Honest Comparison

Every patient asks this question. Most websites avoid giving a straight answer. Here is the honest comparison based on published clinical data:

Factor	Open Surgery	VATS	Da Vinci Robotic
Incision Size	12 to 25 cm	0.5 to 1.5 cm ports	0.8 cm ports (4 to 5)
3D Vision	Naked eye only	2D flat camera	3D HD, 10x magnification
Instrument Dexterity	Full arm movement	4 degrees of freedom	7 degrees of freedom
Blood Loss (avg.)	High	Moderate	Lowest (41% less vs VATS*)
Hospital Stay	6 to 10 days	3 to 6 days	1 to 3 days (many cases)
Return to Normal Life	6 to 12 weeks	3 to 6 weeks	2 to 4 weeks
Tremor Filtering	None	None	Yes, built-in
Lymph Node Removal	Good	Moderate	Most thorough of all three
Surgeon Fatigue	High (standing, bent)	High (standing, bent)	Low (seated console)

*Source: PubMed comparative study on intraoperative blood loss in robotic vs. VATS lobectomy. Robotic average: 219 mL. VATS average: 374 mL.

The Honest Truth:  A major analysis of 14 studies showed that Da Vinci robotic surgery and VATS produce similar long-term survival rates for non-small cell lung cancer. What robotic surgery delivers is not a longer life as a guarantee. What it delivers is a significantly better surgical experience, more thorough lymph node staging, less pain, less blood loss, and a much faster return to normal life. That matters deeply to real patients and their families.

 

What Most Websites Don't Tell You: ICG Fluorescence Imaging

This is something I rarely see discussed in patient-facing content, and I think that is a serious gap. Inside the Da Vinci system is a feature called FIREFLY, which uses a dye called ICG (Indocyanine Green) to light up invisible anatomy under near-infrared light.

When ICG is injected into the bloodstream, it glows bright green under infrared light at the surgeon's console. This makes blood vessels, lymph nodes, and tissue boundaries visible in ways that no other technology currently offers during live surgery.

How ICG Fluorescence Helps Patients Directly

• During esophageal cancer surgery: After rebuilding the food pipe using the stomach, ICG immediately shows whether blood supply is reaching the new connection. If the glow is weak, we adjust before closing. This dramatically reduces the risk of anastomotic leaks, which are a serious and sometimes fatal complication of esophageal surgery.
• During lung segmentectomy: It reveals the exact boundary between the segment to be removed and the healthy lung that must stay. This precision means patients keep as much healthy lung as possible.
• Lymph node mapping: ICG lights up lymph nodes in real time, allowing more accurate and complete cancer staging during the same operation.
• Finding small hidden nodules: Tiny tumours that are not visible on the lung surface can be located using ICG after the injection marks the area.

Surgeons at Cleveland Clinic describe ICG fluorescence as 'surgical reassurance'. I would describe it as turning the lights on in a room you used to navigate in the dark.

 

The Limitations Section No One Wants to Write (But Every Patient Deserves to Read)

I am going to be completely honest here, because I believe patients deserve the truth and not just a sales pitch.

Robotic surgery is not the right choice for every patient or every situation. A surgeon who tells you otherwise is not giving you the full picture.

When Robotic Thoracic Surgery May Not Be the Best Option

• Very large tumours invading the heart or great vessels: In these cases, open thoracotomy often remains the safest approach to achieve complete removal with adequate control.
• No haptic (touch) feedback: Unlike open surgery, a robotic surgeon cannot physically feel tissue resistance. The Da Vinci system does not transmit touch sensation to the surgeon's hands. This gap is compensated for by enhanced 3D vision and years of trained pattern recognition. But it is a real difference, and worth knowing.
• Extensive prior chest surgery with severe scarring: Dense adhesions from previous operations can make robotic approaches more challenging, and some cases require conversion to open surgery mid-procedure.
• Emergency situations: When rapid haemostasis is needed in a life-threatening bleed, speed may outweigh the benefits of minimally invasive access.

A surgeon who knows when NOT to use robotic surgery is a better surgeon than one who uses it on every patient. My decision on your surgical approach will always be based on what is safest and most effective for your specific anatomy, your disease, and your overall health.

Questions You Should Ask Before Consenting to Chest Surgery

Whether you are consulting an oncologist in Gurgaon, seeking thoracic surgery in Delhi, or getting a second opinion anywhere in the world, these questions matter:

1. How many robotic thoracic procedures have you personally performed at this hospital?
2. Are you Da Vinci certified and trained on the specific model used in this hospital?
3. Is robotic surgery the right approach for my specific diagnosis and anatomy, or would VATS or open surgery serve me better?
4. What happens if the robotic approach needs to be converted to open mid-surgery?
5. Does this hospital use ICG fluorescence during esophageal or lung surgery?
6. What does a realistic recovery timeline look like for my specific procedure?
7. Will I need chemotherapy or radiation after this, and how does surgical approach affect that plan?

A good surgeon will welcome every single one of these questions. If your surgeon seems impatient with them, that itself is important information.

 

Closing the Loop: What This Technology Really Means for You

Remember the school teacher from Faridabad I told you about at the beginning? She returned to her classroom six weeks after surgery. She sent me a photograph from her school's annual function. She was standing in front of her students, holding a small award they had made for her. A paper certificate that said, in a child's handwriting: 'Our favourite teacher, back again.'

Robotic thoracic surgery did not just remove a tumour from her lung. It gave her a future that felt whole. That is what this technology is really about. Not the robot. Not the console. Not the 3D camera or the 7-degree wrists. It is about patients leaving the hospital feeling like human beings, not like they have just survived a war.

Here is a quick summary of what we covered:

• The Da Vinci system gives surgeons 10x magnified 3D vision and 7-degree flexible instruments through tiny incisions.
• The chest is one of the best anatomical spaces for robotic surgery because of its rigid, stable structure.
• Robotic surgery reduces blood loss by 41%, hospital stays by several days, and recovery time by weeks compared to open surgery.
• ICG fluorescence imaging allows surgeons to see blood supply and lymph nodes in real time, improving safety and precision.
• Robotic surgery has limitations, and an honest surgeon will tell you when it is not the right choice for you.
• Surgeon experience matters far more than the machine. Always ask about training, certification, and procedure volume.
