Pulmonary resection is a major surgical procedure that removes damaged or diseased lung tissue, offering hope to patients with conditions ranging from lung cancer to severe infections. Understanding what happens during and after this surgery, including recovery expectations and potential complications, helps patients and their families prepare for the journey ahead.

Understanding Surgical Options for Lung Disease

When lung tissue becomes severely damaged by cancer, infection, or other diseases, removing the affected portion may become necessary to protect overall health. Pulmonary resection, also called lung resection, is a surgical treatment that involves removing part or all of a lung. This procedure serves multiple purposes: it can eliminate cancerous tissue, treat stubborn infections like tuberculosis or abscesses, manage conditions such as emphysema (a disease where air sacs in the lungs are damaged) or bronchiectasis (permanent widening of airways), and even help doctors obtain tissue samples for diagnosis.^[1][2]

The human body is remarkably adaptable when it comes to lung function. You have two lungs, each divided into sections called lobes—three on the right side and two on the left. While pulmonary resection is considered major surgery, many people live full, active lives with only one lung or with a portion of lung tissue removed. The remaining healthy lung tissue often compensates for what was taken, though recovery requires time and careful management.^[1][10]

Healthcare providers most commonly perform pulmonary resection to treat early-stage lung cancer, particularly stages I, II, and sometimes stage III non-small cell lung cancer. The procedure may also address cancer that has spread to the lungs from other organs, non-cancerous lung tumors, lung nodules, and various infectious or inflammatory conditions. In some cases, doctors use the procedure diagnostically, removing tissue samples to identify the exact nature of lung problems when less invasive methods haven’t provided clear answers.^[1][4]

Types of Lung Resection Procedures

Surgeons choose from several types of pulmonary resection depending on how much lung tissue needs removal and where the problem is located. A wedge resection removes only a small, wedge-shaped section of lung tissue—the least extensive option that takes out the affected area with some surrounding healthy tissue. This approach removes less lung tissue than more extensive procedures and may be appropriate for small, localized problems or for obtaining tissue samples.^[1][2]

When a slightly larger area requires removal, surgeons may perform a segmentectomy, which takes out one to four portions of a lobe while preserving the rest. This technique aims to remove diseased tissue without sacrificing excess healthy lung, though it is technically more demanding than simpler approaches.^[1][15]

The most common type of pulmonary resection is lobectomy, where surgeons remove one complete lobe of the lung. This procedure is typically the main treatment for people with early-stage lung cancer, tuberculosis, emphysema, bronchiectasis, fungal infections, and non-cancerous tumors. A specialized version called sleeve resection or sleeve lobectomy involves removing part of the lung along with a section of the main bronchus (the airway leading to that lung section), then reconnecting the remaining healthy bronchus to preserve as much lung function as possible.^[1][2][9]

For more extensive disease affecting multiple lobes on the right side, a bilobectomy removes two lobes. When disease involves the entire lung, surgeons perform a pneumonectomy, removing the complete lung. This most extensive option is reserved for situations where less radical surgery won’t adequately treat the condition, as removing an entire lung carries higher risks and requires the remaining lung to handle all breathing function.^[1][2]

Another specialized procedure, lung volume reduction surgery, removes pockets in the lungs containing trapped air, typically performed for severe emphysema. Each type of resection balances the need to remove all diseased tissue against the goal of preserving as much healthy lung function as possible.^[1]

Surgical Approaches: Minimally Invasive Versus Open Surgery

Surgeons can perform pulmonary resection using two main surgical approaches, each with distinct advantages. Thoracoscopic surgery, including video-assisted thoracoscopic surgery (VATS) and robotic video-assisted thoracoscopic surgery (RVATS), represents the minimally invasive option. During these procedures, surgeons make several small incisions, typically 2 to 3 inches long, and insert a thoracoscope—a thin, lighted tube with a camera—along with specialized surgical instruments. The camera provides clear, magnified views of the surgical area on video monitors, allowing surgeons to work with precision through these smaller openings.^[1][2]

Robotic systems take minimally invasive surgery further by translating the surgeon’s hand and wrist movements into precise movements of miniaturized instruments inside the body. The robotic platform offers enhanced three-dimensional vision and allows surgeons to perform complex maneuvers through very small incisions. Boston Children’s Hospital reports that using robotic technology for lung resection results in less pain, smaller scars, faster recovery, shorter hospital stays, and reduced infection risk compared to traditional open surgery.^[5][9]

The alternative approach, open surgery or thoracotomy, involves making a larger incision, typically 8 to 10 inches long, in the side of the chest between the ribs. The surgeon spreads the ribs apart to directly access the lungs. While more invasive than thoracoscopic methods, open surgery may be necessary for more complex cases or when better access to the surgical area is required. The choice between minimally invasive and open approaches depends on the specific medical condition, tumor location and size, the patient’s overall health, and the surgeon’s expertise.^[1][2]

Research increasingly shows that minimally invasive techniques offer significant benefits. However, pulmonary sleeve resection—a particularly complex lung surgery—remains technically challenging even for experienced surgeons, and only certain specialized centers have the expertise to perform these advanced procedures using minimally invasive methods.^[9]

Preparing for Pulmonary Resection

Thorough preparation helps reduce complications and improves surgical outcomes. Before surgery, your healthcare provider will give you detailed instructions that you should follow closely. You’ll need to inform your medical team about all medications you take, including over-the-counter drugs and supplements, and whether you have any implanted medical devices like joint replacements, artificial heart valves, or pacemakers.^[1][2]

Typical preparation steps include fasting—not eating or drinking anything for a specified period before the procedure, usually after midnight the night before surgery. Your doctor may ask you to stop taking certain medications or adjust your medication schedule, though you should never stop medications without explicit instructions from your healthcare provider. If you smoke, stopping before surgery is crucial, as smoking interferes with healing and increases complication risks. You’ll need to arrange for someone to drive you home and plan to spend several days in the hospital for initial recovery.^[1][8]

Before surgery, your medical team may order various diagnostic tests to assess your condition and surgical readiness. These commonly include blood tests, chest X-rays, computed tomography (CT) scans, magnetic resonance imaging (MRI), tissue biopsies, bronchoscopy (a procedure using a thin tube with a camera to look inside airways), and positron-emission tomography (PET) scans. These tests help doctors determine the extent of disease, plan the surgical approach, and evaluate your lung function and overall health.^[1][2]

On the day of surgery, you’ll change into a hospital gown and receive an intravenous (IV) line in your arm to deliver medications and fluids. The surgical team will administer general anesthesia, meaning you’ll be completely unconscious during the procedure and won’t feel any pain. A breathing tube will be placed in your throat to help you breathe during surgery, managed by specialized equipment and the anesthesia team.^[2][7]

What Happens During the Surgery

The duration of pulmonary resection varies based on the complexity of the procedure, typically taking anywhere from two to six hours. During the surgery, whether performed through minimally invasive or open techniques, the surgeon carefully identifies and removes the diseased lung tissue. For cancer cases, nearby lymph nodes and some surrounding tissue are often removed as well to ensure no cancer cells remain.^[2][4]

During thoracoscopic procedures, surgeons work through small incisions using long, specialized instruments while watching video monitors. The surgical area is carefully examined, blood vessels and airways are sealed and divided, and the diseased tissue is removed through one of the small incisions or through a slightly larger extraction site. For open surgery, the larger incision provides direct visual access to the lungs, allowing the surgeon to work with conventional surgical instruments.^[1][2]

For sleeve resection, the procedure becomes more complex. After removing the diseased portion of lung and the affected section of bronchus, the surgeon must carefully reconnect the remaining healthy bronchus to restore airway continuity. This bronchoplasty (reconstruction of the airway) requires precise surgical technique but allows more lung tissue to be preserved compared to removing an entire lung.^[9]

Once the resection is complete, the surgeon closes the incision with stitches or staples. Before closure, one or more chest tubes (drainage tubes) are typically placed through small openings in the chest wall. These tubes drain air, blood, and fluid from the chest cavity during the initial recovery period, helping the remaining lung re-expand and function properly. The tubes remain in place for several days or about a week after surgery until drainage decreases sufficiently.^[1][8]

Recovery in the Hospital

After surgery, you’ll be moved to a recovery area and then to a hospital room, often spending time in an intensive care unit for close monitoring. Most patients stay in the hospital for approximately three to seven days following pulmonary resection, though the exact length depends on the type of surgery performed and how quickly you recover.^[1][2]

In the immediate postoperative period, you’ll likely feel short of breath and experience chest discomfort. Your chest may be sore, swollen, and painful, especially around the incision site. Healthcare providers will give you pain medications to manage discomfort, and taking these medications as prescribed—at regular intervals rather than waiting until pain becomes severe—helps control pain more effectively.^[8][18]

The chest tubes placed during surgery will drain fluid from your chest, and nurses will monitor the drainage and care for the tubes. You may also have other tubes and monitoring equipment, such as IV lines, oxygen delivery systems, and devices to check blood pressure. At first, you may need supplemental oxygen through a mask or nasal cannula (a thin plastic tube resting just inside the nostrils) to ensure your body receives adequate oxygen while your lungs adjust.^[8][18]

Hospital staff will encourage you to get out of bed and begin walking as soon as possible, often within a day of surgery. Early mobilization helps prevent complications such as blood clots, pneumonia, and muscle weakness. Physical therapists may work with you to regain strength and mobility. The hospital team will also monitor your recovery progress, including checking your incision for signs of infection, assessing your pain levels, monitoring your breathing and oxygen levels, and ensuring you can eat, drink, and perform basic activities before discharge.^[8][21]

Recovering at Home

Once you return home from the hospital, recovery continues for several weeks to months. It’s common to feel tired for six to eight weeks after surgery, and getting adequate sleep supports healing. Your chest may hurt and remain swollen for up to six weeks, and you might experience aching or stiffness for up to three months. You may also feel tightness, itching, numbness, or tingling around the incision site for up to three months as nerves heal.^[8][18]

Your stitches or staples will typically be removed at a follow-up appointment one to two weeks after surgery. Some surgeons use dissolvable stitches that don’t require removal. If you still have chest drainage tubes when you leave the hospital, your doctor will remove them during a follow-up visit, usually about a week after surgery.^[8][18]

Gradually increasing physical activity aids recovery, but you must balance activity with adequate rest. Try to walk a little more each day, incrementally increasing the distance. Walking promotes blood flow and helps prevent pneumonia and constipation. However, avoid strenuous activities such as bicycle riding, jogging, weightlifting, aerobic exercise, swimming, tennis, and golf for six to eight weeks or until your doctor approves them. These activities can strain chest and shoulder muscles that are still healing.^[8][18][19]

For six to eight weeks, avoid lifting anything heavier than about 2 kilograms (roughly 4.5 pounds) or anything that makes you strain. This includes children, heavy grocery bags, briefcases or backpacks, pet food bags, and vacuum cleaners. Your doctor will advise you when you can resume driving, which depends on your pain levels, medication use, and ability to perform necessary movements safely. Most people need one to two months off work, though the exact timeframe depends on the type of work you do and how you feel.^[8][18]

Special precautions apply to activities involving air pressure changes. Don’t fly in airplanes or dive deeply (such as scuba diving) until your doctor confirms it’s safe. These activities can affect the healing lungs and potentially cause complications.^[8][18]

Managing Side Effects and Complications

While pulmonary resection carries relatively low overall risk when performed by experienced surgical teams, certain side effects and potential complications require awareness. Common side effects include discomfort or difficulty breathing, which doctors can manage with appropriate medications and breathing support as you recover. Pain around the incision sites, usually controllable with ibuprofen or other pain medications, is expected. Side effects from anesthesia such as nausea, vomiting, sore throat, headache, or difficulty urinating typically resolve within days. Some swelling around surgical sites is also normal.^[4][7]

More serious complications, though less common, can include air leaks in the lung or inability of the remaining lung to fully re-expand and fill normally with air. Infections can develop at the surgical site or in the lungs, and bleeding may occur during or after surgery. Rarely, injury to the lungs or blood vessels in the lungs can happen during the procedure. Repeated fluid buildup in the lung or the development of empyema (a collection of pus in the space between the lung and chest wall) may require additional treatment.^[4][7]

Research indicates that postoperative pulmonary complications such as pneumonia, empyema, and atelectasis (collapse or incomplete expansion of lung tissue) occur in approximately 10% of lung resection cases in recent studies. Development of these complications is associated with increased hospital length of stay, longer intensive care stays, and increased mortality within 30 and 90 days after surgery. This makes preventing complications through proper care critically important.^[14]

To minimize complications, healthcare teams may use several evidence-based interventions. Appropriate antibiotic prophylaxis (preventive antibiotics given before surgery) helps prevent infections. During surgery, careful ventilatory strategies protect the lungs. After surgery, chest physiotherapy, proper sputum management (helping clear mucus from airways), and sometimes non-invasive ventilatory support assist recovery. Risk assessment tools help identify patients who may be at higher risk for complications so extra precautions can be taken.^[14]

Contact your doctor immediately if you experience warning signs such as fever, increasing redness, swelling, or drainage from your incision, chest pain that worsens or doesn’t improve with prescribed medication, severe shortness of breath or difficulty breathing, coughing up blood, or signs of blood clots such as swelling, pain, or warmth in your legs.^[8][18]

Long-term Outlook and Quality of Life

The long-term outlook for most patients who undergo pulmonary resection is positive, particularly when the surgery successfully removes diseased tissue and the patient follows recovery recommendations. For lung cancer patients specifically, meta-analyses have demonstrated better survival rates and improved quality of life in patients with early-stage locally advanced lung cancer who underwent pulmonary sleeve resection compared to traditional pneumonectomy (complete lung removal). This reflects the benefit of lung-sparing surgical approaches that preserve more healthy lung tissue.^[9]

Recovery of lung function takes time. It typically takes six to twelve months to fully regain pulmonary function after lung resection. During this period, the remaining healthy lung tissue gradually compensates for what was removed, and breathing capacity improves. Many patients eventually return to most or all of their previous activities, though this depends on factors such as the amount of lung removed, the patient’s overall health before surgery, and whether other lung diseases are present.^[19]

For cancer patients, pulmonary resection may be followed by additional treatments such as chemotherapy, radiation therapy, or immunotherapy three to five weeks after surgery, depending on the cancer type and stage. These additional treatments aim to eliminate any remaining cancer cells and reduce recurrence risk. The healthcare team works together to create a comprehensive treatment plan tailored to each patient’s specific situation.^[22]

Nutritional support plays an important role in postoperative recovery and overall well-being. Lung cancer patients particularly require additional nutritional support after surgery to expedite wound healing, reduce postoperative complication risk, and enhance quality of life. Key nutrients such as protein, vitamin C, and zinc are critical during this healing process. However, patients often face challenges including appetite loss, digestive issues, changes in taste and smell perception, and emotional aspects affecting nutrition.^[24]

Developing personalized dietary plans that include easily chewable foods, small frequent meals, avoidance of irritating foods, and consideration of nutritional supplementation while controlling dietary fiber helps support recovery. Close cooperation between patients, healthcare professionals, and dietitians facilitates faster, smoother recovery and improves quality of life. You can eat a normal diet after surgery, though if your stomach is upset, bland, low-fat foods like plain rice, broiled chicken, toast, and yogurt may be easier to tolerate. Ask your doctor about appropriate fluid intake, as staying well-hydrated supports healing.^[8][18][24]
