Lung surgery is a critical procedure that helps treat various respiratory diseases and conditions. Among the range of lung surgeries performed, lobectomy is considered the most common. A lobectomy involves the removal of one of the lobes of the lung. This procedure is typically used to treat lung cancer, infections, or other conditions that impair lung function.
Given the essential role of the lungs in oxygenating the body, any surgery involving them requires careful planning, expert medical intervention, and a well-executed post-operative care plan.In this article, we will delve deeper into lobectomy as the most common lung surgery, examining the conditions it treats, the procedure itself, recovery, and other surgical options that might be considered depending on the patient’s condition.

Conditions Requiring Lung Surgery
There are several conditions that may require lung surgery, with lung cancer being one of the most common reasons. Other conditions, such as chronic infections, emphysema, or even congenital abnormalities, may also necessitate surgical intervention.
Lung Cancer
Lung cancer is the leading cause of death from cancer worldwide, and it is one of the primary reasons people undergo lung surgery. There are two main types of lung cancer:
- Non-small cell lung cancer (NSCLC): The more common type, which is less aggressive than small cell lung cancer.
- Small cell lung cancer (SCLC): A rarer, more aggressive form of cancer that tends to spread more quickly.
When lung cancer is detected early, surgery may be the best option to remove the tumour and prevent further spread. The extent of surgery depends on the tumour’s size, location, and whether the cancer has spread to surrounding tissues or lymph nodes.
Infections
Chronic infections, such as tuberculosis or bacterial pneumonia, can lead to significant damage in the lungs, causing the destruction of lung tissue and impaired function. In cases where infections are resistant to antibiotics or are causing severe complications, a surgeon may opt for a lobectomy to remove the infected part of the lung.
Emphysema And Chronic Obstructive Pulmonary Disease (COPD)
Emphysema is a form of chronic obstructive pulmonary disease (COPD) characterised by damage to the alveoli, or air sacs, in the lungs. As the condition worsens, parts of the lung become irreversibly damaged, and the lung loses its ability to expand and contract effectively.
In some severe cases of emphysema, a surgery called lung volume reduction surgery (LVRS) may be performed, which involves removing the damaged parts of the lungs to improve breathing function.
Pulmonary Fibrosis
Pulmonary fibrosis refers to the scarring or thickening of lung tissue, which makes it difficult for the lungs to work properly. In severe cases of pulmonary fibrosis, when the scarring has significantly affected lung function, a lung transplant or a lobectomy may be considered to remove the damaged tissue and improve overall respiratory function.
Lobectomy: The Most Common Lung Surgery
Among the various surgical options for treating lung conditions, lobectomy remains the most commonly performed procedure. It is often used to treat lung cancer, but it can also be employed for other diseases or abnormalities.
What Is Lobectomy?
A lobectomy is a surgical procedure where one lobe of the lung is removed. This surgery may be performed to treat a tumour, chronic infections, or other lung diseases that have caused significant damage to the lung tissue. Depending on the extent of the disease, a wedge resection (removal of only a small section of lung tissue) or a pneumonectomy (removal of the entire lung) may also be necessary, although these are less common than a lobectomy.
Types Of Lobectomy
- VATS Lobectomy (Video-Assisted Thoracoscopic Surgery): VATS is a minimally invasive technique where the surgeon uses small incisions and a video camera to guide the procedure. This approach reduces recovery time and complications compared to traditional open surgery.
- Open Lobectomy: This involves a larger incision in the chest to allow the surgeon full access to the lung. Open lobectomy is generally performed when the tumour is larger or in a location that is difficult to reach with VATS.
- Robotic-Assisted Lobectomy: A newer technique that uses robotic arms to enhance the precision of the surgery. This approach combines the benefits of minimally invasive surgery with advanced technology to improve outcomes.
The Procedure: How Is A Lobectomy Performed?
Lobectomy, whether performed via VATS or open surgery, generally follows a similar set of steps:
- Anaesthesia: The patient is put under general anaesthesia to ensure they are unconscious and pain-free during the surgery.
- Incision: For VATS, a small incision is made on the side of the chest, through which a tiny camera (thoracoscope) is inserted to guide the surgeon. In open lobectomy, a larger incision is made to give the surgeon more direct access to the lung.
- Removal of the Lobe: The surgeon isolates the affected lobe, cutting through blood vessels and airways connecting it to the rest of the lung. The lobe is then removed, and any remaining lung tissue is sealed off to prevent air leaks.
- Closure: Once the procedure is complete, the incisions are closed, and a drainage tube may be inserted temporarily to remove any excess fluid or air from the chest cavity.
- Recovery: After the surgery, the patient is closely monitored in a recovery room for a few hours. They are typically kept in the hospital for several days for observation and to manage pain and any complications.
Recovery After Lobectomy
Recovery after a lobectomy can vary depending on the type of surgery performed (VATS vs. open lobectomy), the patient’s overall health, and the reason for the surgery. Generally, the recovery process involves the following:
- Hospital Stay: Most patients stay in the hospital for 3-7 days, during which they are monitored for complications such as infections or bleeding.
- Pain Management: Pain after lobectomy is common, but it can be managed with medications. Patients are usually given painkillers to keep them comfortable during recovery.
- Breathing Exercises: After surgery, patients are encouraged to perform deep breathing exercises to help expand the lungs and prevent complications like pneumonia.
- Physical Activity: Physical activity should be gradually increased after surgery, as exercise helps promote lung function and overall recovery. However, patients should avoid heavy lifting or strenuous activities for several weeks.
- Follow-up Care: Regular follow-up appointments with the surgeon are crucial to ensure that healing is progressing and to detect any signs of complications, such as infections or recurrence of cancer.
Risks And Complications
As with any surgery, lobectomy carries certain risks, including:
- Infection: Any surgery carries the risk of infection, especially since the lungs are directly involved.
- Air Leaks: A potential complication where air leaks from the lung into the chest cavity, which may require additional treatment.
- Bleeding: While rare, significant bleeding can occur during surgery.
- Pneumonia: Pneumonia can develop after surgery, particularly if the patient has a weakened immune system.
- Recurrence of Disease: In the case of cancer, there is always the possibility that the disease could return after surgery, which requires further treatment or intervention.
Conclusion
Lung surgery, specifically lobectomy, plays a vital role in the treatment of lung diseases, particularly lung cancer. By removing the diseased portion of the lung, doctors aim to improve the patient’s lung function, quality of life, and survival chances. While lobectomy is a common and generally safe procedure, it carries risks, and recovery can be challenging.
However, with modern surgical techniques such as VATS and robotic-assisted surgery, recovery times have been reduced, and patient outcomes have improved. If you’re considering or undergoing lung surgery, it’s essential to discuss all available options with your doctor. They can provide guidance based on your specific condition, ensuring the best possible care and outcome.
Frequently Ask Question
Why Is A Lobectomy Performed?
A lobectomy is primarily performed to treat lung cancer when the tumour is confined to one lobe of the lung and has not spread to other areas. It may also be used in cases of severe lung infections, like tuberculosis, or in patients with chronic obstructive pulmonary disease (COPD), where a portion of the lung is damaged. The surgery is intended to improve the patient’s lung function by removing the damaged or diseased tissue. A lobectomy can also help prevent the disease from spreading to other parts of the lung or body.
What Are The Risks Of Lung Surgery?
As with any major surgery, lung surgery carries risks, including bleeding, infection, and complications related to anaesthesia. Specific risks for lung surgery include damage to surrounding organs, such as the heart or diaphragm, and the possibility of air leaks from the lung. There is also the risk of lung collapse, which may require further medical intervention. After surgery, some patients may experience shortness of breath or reduced lung function, but these effects often improve over time with rehabilitation and breathing exercises.
How Is A Lobectomy Performed?
A lobectomy can be performed using either traditional open surgery or minimally invasive techniques. In traditional surgery, a large incision is made in the chest to access the lung. In minimally invasive surgery, a series of smaller incisions are made, and a camera and specialised tools are used to remove the lobe of the lung. The choice of technique depends on the size, location of the tumour, and the patient’s overall health. The surgeon will also decide the best approach based on the potential risks and benefits for the patient.
