How Is Thoracic Surgery with the da Vinci Xi Surgical Robot Beneficial?

WIPHUT KOCHARUNJITT,M.D.

Thoracic diseases are a group of diseases involving important organs such as the lungs, bronchi, and thymus gland. In many cases, they may not show symptoms in the early stage but can progress to severe conditions if not diagnosed and treated promptly, especially lung masses or lung cancer, for which surgery is the main treatment approach.

At present, medical technology has continuously advanced, particularly surgery using the da Vinci Xi surgical robot, which plays a role in increasing precision, allowing surgeons to access complex locations within the thoracic cavity more effectively through small surgical incisions, resulting in more effective and safer treatment.

What Is the da Vinci Xi Surgical Robot Technology?

The da Vinci Xi surgical robot is a minimally invasive surgical technology designed to allow surgeons to precisely control surgery through a console system. It is equipped with intelligent robotic arms that move freely like the human wrist, enabling the instruments to efficiently access complex or difficult-to-reach locations within the thoracic cavity.

The system is equipped with a high-definition 3D camera, allowing surgeons to see internal structures more clearly and with greater depth, enabling more precise dissection of tissues and blood vessels.

Although minimally invasive surgery (MIS) can also be performed through small incisions, in some locations, such as beneath the ribs, irritation from the surgical instruments may occur. The da Vinci Xi robot is designed with a stable pivot point at the chest wall, helping reduce unnecessary movement, thereby reducing tissue irritation and helping patients experience less postoperative pain.

Why Is Surgery Important for Thoracic Diseases?

Surgery is important in the treatment of thoracic diseases, especially lung masses, which are often found as "lung nodules" and require close follow-up and evaluation. If there are additional indications, the physician will perform endoscopy to obtain a tissue sample for diagnosis. If lung cancer is confirmed, surgery remains the current standard treatment.

Robotic surgical technology is therefore used to improve efficiency by combining the advantages of open surgery and minimally invasive surgery. It allows for small incisions while providing more precise control in grasping and dissecting tissues and blood vessels. It also provides magnified 3D images, allowing small structures to be seen clearly, resulting in safer surgery.

Thoracic Diseases That Can Be Treated with the da Vinci Xi Surgical Robot

Lung Cancer / Lung Nodules

This is the main group of diseases commonly found, especially in patients whose health check-up reveals "lung nodules," which require follow-up or further diagnosis. If cancer is confirmed, surgery is the standard treatment, and the surgical robot helps provide more precise access to the tumor and lymph nodes.

Thymoma

It is commonly found in the anterior chest and may not show symptoms in the early stage. As the tumor enlarges, it may compress adjacent organs. Surgery is the main treatment approach, and the surgical robot helps surgeons perform surgery more precisely in difficult-to-access areas.

Myasthenia Gravis

In some patients, there is an indication for thymectomy. The use of the surgical robot increases surgical precision and reduces trauma to surrounding tissues.

What Are the Advantages of the da Vinci Xi Surgical Robot for Thoracic Diseases?

Small surgical incisions, shorter recovery period, reduced hospital stay
Less blood loss than open surgery
Better access to the surgical site
Clearer 3D visualization during surgery, even in complex locations, helping reduce the chance of injury or side effects during surgery
7 Degrees of Freedom The robotic arms can rotate and articulate freely like the human wrist, allowing better access to complex or confined locations compared with conventional straight laparoscopic instruments, resulting in more delicate and precise surgery.
Tremor Filtration Helps reduce tremors from the surgeon's hands, allowing dissection or separation of important tissues, such as pulmonary blood vessels, to be performed more steadily and safely, reducing the risk of injury to surrounding tissues.
The surgeon can sit and control the surgery through the console system, allowing continuous and more efficient control during long procedures.

Who Is Suitable for Thoracic Surgery with the da Vinci Xi Surgical Robot?

Patients with tumors or masses in the thoracic cavity
Patients with small to medium-sized masses
Patients whom the physician has assessed as physically ready for robotic surgery
Patients with physical fitness suitable for surgery, such as adequate lung function, because the main limitation is not the robotic technology but the patient's physical ability to undergo surgery.

The choice of surgical method depends primarily on the physician's assessment. The surgical robot helps increase precision and is particularly suitable for complex cases.

Preparation Before Thoracic Surgery with the da Vinci Xi Surgical Robot

1. Inform your physician of your medical history in detail, such as drug allergies, food allergies, and underlying diseases.

2. Inform your physician of any previous thoracic surgery or procedures, such as chest tube insertion or previous chest infection, as these may cause adhesions and affect the difficulty of the surgery.

However, due to the advantages of the da Vinci Xi surgical robot in providing precise movement control and better access to confined spaces, surgery in some cases with adhesions may be easier than minimally invasive surgery.

3. Assess physical readiness before surgery, such as pulmonary function testing, to determine whether surgery can be performed safely.

4. Stop certain medications before surgery, especially those that affect blood clotting, such as anticoagulants (e.g., Warfarin), which are generally discontinued approximately 3–5 days in advance. Some medications may need to be stopped 5–7 days in advance, depending on the physician's recommendation.

5. Discontinue certain dietary supplements and vitamins, such as ginkgo, lingzhi mushroom, or certain vitamins that may increase the risk of bleeding. They are generally recommended to be stopped approximately two weeks before surgery.

Preparation before robotic surgery follows principles similar to those of general surgery, and the physician will assess suitability on an individual basis.

Self-Care After Thoracic Surgery with the da Vinci Xi Surgical Robot

Do not smoke before or after surgery.

People who continue smoking have a higher risk of postoperative complications, such as pneumonia, lung infection, or the need for mechanical ventilation, due to reduced function of the airway mucus clearance system.

Practice breathing exercises and lung rehabilitation continuously.

Breathing exercises before and after surgery help the lungs recover better. They should be continued after surgery to help the lungs fully expand and reduce mucus retention.

Cough and clear mucus properly.

Because the lung is collapsed during surgery, mucus retention may occur. Practicing coughing and mucus clearance helps reduce the risk of lung infection.

Strengthen the respiratory muscles.

The intercostal muscles and diaphragm play important roles in breathing. After surgery, stronger muscles help speed recovery.

Attend follow-up appointments and take medications as prescribed by the physician.

Postoperative follow-up is important to assess recovery and prevent complications.

Observe for abnormal symptoms after surgery, such as difficulty breathing, excessive coughing, or fever, and seek medical attention immediately.

Overall, postoperative care follows principles similar to those of general surgery, but continuous lung rehabilitation during the first 1–3 months after surgery is an important factor in improving recovery.

Frequently Asked Questions About Thoracic Surgery with the da Vinci Xi Surgical Robot

1. What are the risks or complications of surgery with the da Vinci Xi surgical robot?

Complications such as wound infection, bleeding, or air leakage from the lung may occur. These are uncommon, and the physician will monitor them closely.

2. Does thoracic surgery with the da Vinci Xi surgical robot require a long hospital stay?

In general, after surgery, patients remain in the hospital for approximately 1–2 days for observation and close monitoring of complications before being considered for discharge.
