Lobectomy and Types of Lung Cancer Surgery

A lobectomy is a surgical procedure that removes an entire lobe of the lung. Because the lungs are divided into distinct anatomical sections, or lobes, a lobectomy allows the surgeon to remove the portion of the lung containing a tumor or other significant disease while preserving the remaining healthy lung whenever possible.

At the Institute for Thoracic Surgery in Miami, Florida, Mark R. Dylewski, M.D., specializes in the surgical treatment of lung cancer and other complex pulmonary conditions. When a lobectomy is appropriate, Dr. Dylewski uses advanced minimally invasive techniques whenever technically and oncologically appropriate, including video-assisted thoracoscopic surgery (VATS), robotic-assisted thoracic surgery, and uniportal approaches.

Types of Lung Cancer Surgery

The appropriate operation for lung cancer depends on several factors, including the type and stage of the cancer, tumor size and location, involvement of surrounding structures or lymph nodes, and the patient's overall lung function and health.

Lobectomy

A lobectomy removes the entire lobe containing the lung cancer and is a standard surgical treatment for many patients with localized non-small cell lung cancer. The procedure is designed to completely remove the tumor along with an appropriate margin of surrounding lung tissue and regional lymph nodes while preserving the remaining lung.

Segmentectomy

A segmentectomy removes a smaller anatomical portion of a lung lobe rather than the entire lobe. In appropriately selected patients, particularly those with small, localized tumors or limited pulmonary reserve, a segmentectomy may provide an effective oncologic resection while preserving more functioning lung tissue.

Wedge Resection

A wedge resection removes the tumor along with a surrounding margin of normal lung tissue without removing an entire anatomical segment or lobe. This more limited operation may be appropriate for selected small peripheral tumors or for patients who may not tolerate a larger lung resection.

Pneumonectomy

A pneumonectomy involves removal of an entire lung. This is a more extensive operation and is generally reserved for tumors that cannot be adequately removed with a smaller anatomical resection. Because removing an entire lung has a substantial impact on respiratory reserve, careful evaluation is essential before considering this procedure.

Lymph Node Evaluation and Dissection

Lung cancer surgery frequently includes evaluation or removal of lymph nodes within the chest. Lymph node assessment provides important information about the extent of disease and helps determine the cancer's stage and whether additional treatment, such as chemotherapy, immunotherapy, or radiation therapy, may be appropriate.

Choosing the Appropriate Operation

There is no single operation that is appropriate for every patient with lung cancer. The surgical plan is determined after careful review of imaging, biopsy and pathology results, pulmonary function, overall health, and the anatomical relationship between the tumor and surrounding structures.

Whenever possible, the goal is to completely remove the cancer while preserving as much healthy, functioning lung tissue as possible.

Dr. Dylewski also emphasizes minimally invasive surgery whenever it can safely accomplish the necessary cancer operation. Depending on the individual circumstances, VATS, robotic-assisted, or uniportal surgery may allow the procedure to be performed through small incisions rather than a traditional open thoracotomy.

For patients with early-stage lung cancer, surgery may provide an opportunity for definitive treatment. More advanced lung cancers may require a multidisciplinary, multimodality approach that combines surgery with systemic therapy, immunotherapy, radiation therapy, or other treatments.

At the Institute for Thoracic Surgery, each patient's treatment plan is individualized to the biology and stage of the cancer, the patient's overall health, and the goal of achieving complete cancer treatment while preserving pulmonary function whenever possible.

If you have been diagnosed with lung cancer or have been told that you may require lung surgery, a consultation with a thoracic surgeon can help you understand the available surgical options and determine which approach may be appropriate for your specific condition.

Lobectomy and Advanced Lung Surgery

A lobectomy is an operation in which an entire lobe of the lung is surgically removed. The right lung contains three lobes, while the left lung contains two. When disease is confined to one lobe, removing that portion of the lung can eliminate the affected tissue while preserving the remaining healthy lung.

Lobectomy is one of the most commonly performed anatomical lung resections for appropriately selected patients with localized non-small cell lung cancer. It may also be considered for certain serious or localized noncancerous lung conditions when removing the diseased portion of the lung is necessary to control the disease or prevent further complications.

At the Institute for Thoracic Surgery in Miami, Florida, Mark R. Dylewski, M.D., specializes in advanced pulmonary surgery and uses a personalized approach to determine both the appropriate extent of lung resection and the safest surgical technique. The operation may be performed through a traditional open approach or using minimally invasive video-assisted thoracoscopic surgery (VATS) or robotic-assisted techniques.

The objective is not simply to remove part of the lung. The goal is to achieve complete and appropriate treatment while preserving as much healthy, functioning lung tissue as possible and minimizing surgical trauma whenever safely possible.

When Is a Lobectomy Recommended?

The most common indication for lobectomy is localized lung cancer, particularly when a tumor is confined to one lobe and the patient is an appropriate surgical candidate.

For lung cancer, surgery generally involves removal of the affected lobe together with evaluation or removal of regional lymph nodes. Examination of the lymph nodes provides important information about whether cancer has spread beyond the primary tumor and helps determine the stage of the disease and the need for additional treatment.

A lobectomy may also be considered for selected noncancerous conditions, including:

• Localized bronchiectasis causing recurrent infections or significant symptoms
• Severe localized emphysema in carefully selected patients
• Destructive or chronic localized lung infections
• Certain congenital or structural abnormalities
• Other conditions in which a portion of the lung has become severely damaged or diseased

The decision to remove an entire lobe rather than a smaller portion of the lung depends on the underlying disease, its location and extent, the patient's pulmonary function, and the ability to achieve an appropriate result with a more limited resection.

Different Types of Lung Resection

Lobectomy is only one type of pulmonary resection. Depending on the disease and the amount of lung that needs to be removed, a thoracic surgeon may perform several different operations.

Wedge Resection

A wedge resection removes a small, non-anatomical portion of lung containing a lesion and a surrounding margin of tissue. It may be appropriate for selected small peripheral tumors, diagnostic procedures, metastatic lesions, or patients who may not tolerate a larger lung resection.

Segmentectomy

A segmentectomy removes an anatomical segment of a lung lobe while preserving the remainder of the lobe. For appropriately selected small lung cancers, segmentectomy can provide an oncologically appropriate resection while preserving more lung tissue than a lobectomy.

Lobectomy

A lobectomy removes an entire anatomical lobe. For many patients with localized non-small cell lung cancer, it remains an important standard surgical approach because it allows removal of the tumor and surrounding lung tissue while providing appropriate margins and regional lymph-node evaluation.

Pneumonectomy

A pneumonectomy removes an entire lung. It is a substantially more extensive operation and is generally reserved for tumors or other diseases that cannot be adequately treated with a smaller resection. Because it results in the loss of an entire lung, careful assessment of pulmonary and cardiovascular function is essential.

The appropriate operation is determined by the disease—not by the technology used to perform the operation.

Open Surgery vs. Minimally Invasive Lung Surgery

Thoracic surgeons have several ways to access the lung. The choice between an open operation and minimally invasive surgery depends on the patient's anatomy, the disease being treated, previous operations, the complexity of the procedure, and the surgeon's ability to safely and completely accomplish the necessary operation.

Open Lung Surgery: Thoracotomy

A traditional thoracotomy uses a larger incision between the ribs to provide direct access to the chest. Although many pulmonary procedures can now be performed minimally invasively, open surgery remains an important option.

A thoracotomy may be necessary when a tumor is particularly large or locally advanced, when it involves structures that require extensive reconstruction, when significant bleeding or another complication requires immediate open access, or when previous surgery or complex anatomy makes a minimally invasive approach inappropriate.

Open surgery provides excellent exposure and direct access to the chest, but it generally involves greater disruption of the chest wall than minimally invasive techniques. Patients may experience more postoperative pain and may require a longer recovery.

Video-Assisted Thoracoscopic Surgery (VATS)

VATS was a major advancement in minimally invasive thoracic surgery. Rather than using a large thoracotomy incision, the surgeon operates through several small incisions using a thoracoscopic camera and specialized instruments.

The camera provides magnified visualization of the chest while the instruments allow the surgeon to dissect and remove the diseased portion of the lung.

For appropriately selected patients, VATS can reduce chest-wall disruption compared with an open thoracotomy and may result in less postoperative pain, shorter hospitalization, and a faster recovery.

However, conventional VATS instruments are relatively straight and have limited articulation. This can make certain technically demanding portions of an operation more challenging.

Robotic-Assisted Lung Surgery

Robotic-assisted thoracic surgery represents another evolution in minimally invasive pulmonary surgery. The robotic system does not operate independently. The surgeon remains in complete control of the instruments throughout the procedure.

Robotic technology provides high-definition, three-dimensional visualization and articulated instruments that can move within the chest with greater flexibility than conventional straight thoracoscopic instruments. This can be particularly useful when performing precise dissection around delicate structures such as pulmonary arteries, veins, bronchi, and lymph nodes.

For appropriately selected patients, robotic surgery can allow complex lung resections to be performed through small incisions rather than a traditional thoracotomy.

Multi-Port Robotic Lung Surgery

In multi-port robotic surgery, the surgeon uses several small incisions to introduce the camera and robotic instruments into the chest. Each instrument is positioned through a separate port, allowing the surgeon to triangulate around the operative field.

This configuration provides considerable instrument mobility and allows multiple robotic arms to approach the anatomy from different directions. It has been widely used for complex pulmonary procedures, including lobectomy and other anatomical lung resections.

Multi-port robotic surgery can be particularly useful when the operation requires extensive dissection, multiple angles of access, or the use of several specialized instruments simultaneously.

Single-Port Robotic Lung Surgery

Single-port robotic surgery uses a different strategy. Rather than placing multiple robotic ports throughout the chest, the robotic instruments and camera are introduced through a single incision.

A single-port system is designed to allow multiple articulating instruments and the camera to work through one access point. This approach can reduce the number of chest-wall incisions while maintaining the visualization and instrument articulation associated with robotic surgery.

Single-port robotic surgery may be particularly attractive for procedures in which the necessary anatomy can be effectively reached through one access point. However, it is not automatically appropriate for every patient or every operation. Tumor location, anatomy, disease extent, previous surgery, and the complexity of the procedure all influence whether a single-port approach can safely accomplish the operation.

Multi-Port vs. Single-Port Robotic Surgery

The distinction between these approaches is primarily how the chest is accessed, rather than whether one is inherently superior to the other.

	Multi-Port Robotic	Single-Port Robotic
Access	Several small incisions	One primary incision
Visualization	Three-dimensional robotic visualization	Three-dimensional robotic visualization
Instruments	Multiple robotic ports/instruments	Multiple articulating instruments introduced through one port
Flexibility	Multiple access points and instrument angles	Instruments work through a single access point
Potential advantage	Versatility for complex dissections	Fewer chest-wall access sites
Selection	Depends on anatomy and complexity	Depends on anatomy and ability to safely reach the operative target

The important consideration is not simply whether an operation is performed robotically. The surgical approach must be selected based on the patient's disease and anatomy and the surgeon's ability to perform a complete, safe operation.

Why Minimally Invasive Surgery May Be Preferred

When a lung operation can be performed safely and completely without a thoracotomy, minimally invasive surgery may offer important advantages. Smaller incisions and reduced chest-wall disruption may contribute to less postoperative discomfort, earlier mobilization, shorter hospitalization, and a faster return to normal activities.

The benefits of minimally invasive surgery must always be balanced against the requirements of the operation. A minimally invasive approach should never compromise the ability to obtain adequate margins, appropriately evaluate lymph nodes, control blood vessels, or otherwise accomplish the necessary surgical treatment.

For this reason, the least invasive operation is not necessarily the smallest operation. The appropriate goal is the least invasive approach that can safely and completely achieve the required treatment.

What Happens During a Lobectomy?

A lobectomy is performed under general anesthesia. Depending on the selected approach, Dr. Dylewski accesses the chest through a thoracotomy, several VATS incisions, or a robotic approach using either multiple ports or a single-port technique.

The pulmonary vessels and airway supplying the affected lobe are carefully identified and divided, and the lobe is separated from the remaining lung. When the operation is being performed for lung cancer, regional lymph nodes are typically evaluated or removed for pathological examination.

The remaining lung is then allowed to re-expand. A temporary chest tube is generally placed to drain air and fluid from the chest while the lung heals.

Recovery After Lung Surgery

Following surgery, patients are monitored for lung expansion, air leakage, bleeding, infection, and other potential complications. Pain management, early mobilization, respiratory therapy, and breathing exercises are important components of recovery.

Recovery varies according to the patient's age, pulmonary function, overall health, the extent of the operation, and the surgical approach used. In general, minimally invasive procedures result in less chest-wall disruption than an open thoracotomy and may facilitate an earlier recovery.

Dr. Dylewski provides individualized postoperative instructions regarding activity, wound care, driving, exercise, work, and follow-up.

An Individualized Approach to Lung Surgery

There is no single surgical technique that is appropriate for every patient. The decision regarding what portion of the lung should be removed and how the operation should be performed requires careful consideration of the diagnosis, tumor size and location, cancer stage when applicable, lymph-node involvement, pulmonary reserve, prior operations, and overall health.

At the Institute for Thoracic Surgery, Dr. Dylewski's approach is centered on achieving the necessary surgical and oncologic result while preserving healthy lung tissue and minimizing surgical trauma whenever appropriate.

Whether a patient requires a wedge resection, segmentectomy, lobectomy, pneumonectomy, or another pulmonary procedure, the surgical plan is individualized to the patient's disease. When technically and oncologically appropriate, advanced minimally invasive techniques—including VATS, multi-port robotic surgery, and single-port robotic surgery—may provide an alternative to traditional open thoracotomy.

If you have been diagnosed with lung cancer or another condition requiring lung surgery, a consultation with a specialized thoracic surgeon can help determine which operation and surgical approach are most appropriate for your individual circumstances.
