Minimally Invasive & Robotic Thoracic Surgery
Minimally invasive thoracic surgery allows many chest procedures to be performed through small incisions rather than a traditional open thoracotomy. At Saint John’s Health Center, thoracic surgeons use video-assisted thoracoscopic surgery (VATS), robot-assisted thoracic surgery (RATS), and open surgical approaches according to the condition being treated, the complexity of the operation, and the individual needs of the patient.
The goal is not simply to use the smallest incision, but to choose the surgical approach that allows safe, effective treatment while minimizing unnecessary trauma. For appropriately selected patients, minimally invasive techniques can reduce postoperative pain and shorten recovery compared with open surgery while maintaining the surgical and oncologic goals of the operation.
What Is Minimally Invasive Thoracic Surgery?
Minimally invasive thoracic surgery uses small incisions and specialized instruments to reach structures inside the chest without widely spreading the ribs. The two principal approaches are video-assisted thoracoscopic surgery (VATS) and robot-assisted thoracic surgery (RATS).
Both techniques allow surgeons to perform operations involving the lungs, mediastinum, diaphragm, esophagus, chest wall, and other thoracic structures. The choice between VATS, robotic surgery, and an open approach depends on the diagnosis, anatomy, extent of disease, complexity of the operation, and the experience of the surgical team.
Video-Assisted Thoracoscopic Surgery (VATS)
VATS uses a small camera called a thoracoscope and surgical instruments inserted through small incisions in the chest. The camera provides a magnified view of the operative field, allowing the surgeon to perform many thoracic procedures without a large open incision or routine rib spreading.
VATS is well established for procedures such as lung resection, pleural surgery, treatment of pneumothorax, mediastinal surgery, and selected esophageal and diaphragm operations.
Robot-Assisted Thoracic Surgery (RATS)
Robot-assisted thoracic surgery uses a surgical robotic system controlled entirely by the surgeon. The system provides a high-definition three-dimensional view of the operative field and articulated instruments that can move with a greater range of motion than conventional straight thoracoscopic instruments.
The robotic system does not perform the operation independently. The surgeon controls the instruments from a console while members of the surgical team assist at the operating table. Robotic surgery can be particularly useful when precise dissection and instrument mobility are important within confined areas of the chest.
What Are the Potential Benefits of Minimally Invasive Thoracic Surgery?
Compared with traditional open thoracic surgery, minimally invasive approaches can reduce the physical impact of an operation in appropriately selected patients. Potential advantages may include:
- Smaller surgical incisions.
- Less postoperative pain.
- Reduced disruption of the chest wall and surrounding tissues.
- Shorter hospital stays for many procedures.
- Earlier return to normal activities.
- Less visible scarring.
These benefits vary according to the specific operation and the patient’s overall health. Minimally invasive surgery does not eliminate surgical risk, and an open procedure may sometimes provide the safest or most effective approach.
How Does Robotic Surgery Assist the Thoracic Surgeon?
Robotic systems are designed to extend the surgeon’s visual and technical capabilities during minimally invasive procedures. Three-dimensional magnified imaging can help surgeons identify important anatomical structures, while wristed instruments allow controlled movements within confined areas of the chest.
These features can be useful during complex dissections around blood vessels, airways, nerves, lymph nodes, and other structures. However, the technology is a surgical tool rather than a substitute for surgical judgment. Outcomes depend on appropriate patient selection, the operation being performed, and the experience of the surgical team.
Current evidence supports both robotic and video-assisted thoracic surgery as effective minimally invasive approaches. For lung cancer surgery, recent randomized and observational evidence generally shows comparable oncologic results between RATS and VATS, although robotic surgery may offer advantages in selected complex operations or reduce conversion to open surgery in some patient groups.
Conditions and Procedures Treated with Minimally Invasive Thoracic Surgery
VATS and robotic techniques can be used for a wide range of thoracic conditions. Whether a minimally invasive approach is appropriate depends on the diagnosis and the extent and location of disease.
Lung Cancer and Pulmonary Nodules
Minimally invasive techniques can be used for wedge resection, segmentectomy, lobectomy, and selected more complex lung resections. For lung cancer, the surgical approach must still allow complete tumor removal and appropriate lymph node evaluation. Learn more about lung cancer treatment.
Mediastinal Tumors and Thymectomy
VATS and robotic surgery can be used to remove selected thymic tumors, cysts, neurogenic tumors, and other mediastinal masses. Robotic approaches can be particularly useful when operating within the confined mediastinum, although larger or invasive tumors may require open surgery. Learn more about treatment for mediastinal tumors.
For selected mediastinal tumors, minimally invasive surgery can offer favorable perioperative outcomes, although patient selection, tumor characteristics, and the ability to perform a safe and complete resection remain important.
Thoracic Outlet Syndrome
Selected patients undergoing first-rib resection and thoracic outlet decompression may be treated using minimally invasive approaches. The operative technique is determined by the type of thoracic outlet syndrome and the anatomy requiring decompression. Learn more about treatment for thoracic outlet syndrome.
Diaphragm Surgery
Minimally invasive techniques may be used for diaphragm plication in selected patients with symptomatic diaphragm paralysis. The procedure stabilizes the affected diaphragm to improve respiratory mechanics. Learn more about treatment for paralyzed diaphragm.
Spontaneous Pneumothorax
Minimally invasive thoracic surgery may be used for recurrent spontaneous pneumothorax, persistent air leaks, or when preventing another episode is particularly important. VATS can be used to treat blebs or bullae and may be combined with pleurodesis to reduce the risk of recurrence. Learn more about treatment for spontaneous pneumothorax.
Esophageal and Other Thoracic Procedures
Minimally invasive approaches may also be used for selected esophageal procedures, pleural surgery, and other thoracic conditions. Some complex operations may combine minimally invasive techniques with other surgical approaches.
When Is Open Thoracic Surgery Still Needed?
Open surgery remains an important part of modern thoracic care. A thoracotomy or sternotomy may be the safest and most effective approach for very large tumors, extensive disease, invasion of major blood vessels or other structures, complex reconstruction, significant scar tissue from previous treatment, or unexpected findings during surgery.
A minimally invasive operation may also need to be converted to an open procedure if the surgeon determines that greater access is necessary to complete the operation safely. Conversion is a surgical decision made to protect the patient and should not be viewed as a failure of minimally invasive treatment.
Choosing the Right Surgical Approach
There is no single surgical technique that is best for every thoracic condition. Treatment planning considers the diagnosis, tumor or disease location, extent of involvement, previous treatments, lung function, overall health, and the technical requirements of the operation.
At Saint John’s, the goal is to use the least invasive approach that can safely accomplish the intended treatment. For some patients that may be VATS or robotic surgery; for others, an open operation may provide the best result.
Advanced Minimally Invasive Thoracic Care
The Pulmonary and Thoracic team at Providence Saint John’s Health Center uses video-assisted, robotic, and open surgical techniques to treat a broad range of thoracic conditions. Each approach is selected according to the patient’s diagnosis, anatomy, health, and the requirements of the operation.
Our thoracic surgeons combine minimally invasive technology with careful surgical planning to reduce unnecessary tissue trauma while maintaining the goals of safe and effective treatment.
If you need thoracic surgery, our specialists can help determine whether a minimally invasive, robotic, or open approach is most appropriate for you.
