Quick Answer: What is thoracic surgery?

Thoracic surgery is any operation on organs inside the chest, including the heart, lungs, esophagus, trachea, diaphragm, chest wall and the space between the lungs. Surgeons use open incisions or minimally invasive tools to treat conditions such as lung cancer, coronary artery disease and hiatal hernia. Hospital stays usually last 3 to 10 days. [1]

What the research says

• Keyhole lung surgery means fewer complications than open surgery. Across 10 studies with 1,514 lung cancer patients, video-assisted (VATS) surgery cut the odds of complications by almost half (odds ratio 0.54) and shortened the hospital stay by about 1.5 days compared with muscle-sparing open surgery. (Wang et al., BMC Surgery, 2019) [4]

• Robotic and video-assisted surgery are similarly safe. A review of 26 studies and 45,733 lung cancer patients found no difference in overall complications or 5-year survival; the robotic group had less blood loss, fewer switches to open surgery and shorter hospital stays. (Zhang et al., Frontiers in Oncology, 2022) [5]

• Exercising before lung surgery helps recovery. In 11 trials with 717 lung cancer patients, preoperative exercise reduced complications by about 50% and shortened the hospital stay by 2.5 days. (Steffens et al., Anesthesia & Analgesia, 2025) [6]

Key takeaways

• Thoracic surgery covers every organ in the chest, not only the heart and lungs.

• The two most common thoracic operations are heart bypass (CABG) and lobectomy.

• Surgery is done through a larger open incision or several small keyhole cuts.

• Most people stay in hospital 3 to 10 days and need a month or more to fully recover.

• Chest pain, shortness of breath, fever or incision problems after surgery need prompt medical attention.

What is thoracic surgery?

Thoracic surgery is surgery on any organ or structure inside the thorax, the part of the body between the neck and the abdomen. [1]

It includes operations on the heart, lungs, esophagus (food pipe), trachea (windpipe), diaphragm and chest wall. It also covers the mediastinum, the space between the lungs that holds the thymus and other structures. [1]

Many thoracic operations are major procedures. A team of specialists plans and coordinates your care before, during and after the operation. [1]

What areas does thoracic surgery treat?

Thoracic surgery treats seven main areas of the chest, and each one has its own group of conditions. [1]

Chest area	Examples of conditions treated
Heart	Coronary artery disease, heart valve disease, arrhythmias, heart failure, congenital heart defects
Major blood vessels	Aneurysms
Lungs	Lung cancer, lung transplant
Esophagus	Esophageal tumors, GERD, Barrett's esophagus, swallowing problems (dysphagia)
Diaphragm	Hiatal hernia
Mediastinum	Thymus tumors
Heart and lungs together	Heart and lung transplants

What are the most common types of thoracic surgery?

The two most common thoracic operations are coronary artery bypass grafting (CABG) and lobectomy. [1][3]

CABG reroutes blood around a blocked heart artery. About 200,000 bypass operations are done in the U.S. each year. [1] Read more in our guide to coronary revascularization with PCI and CABG.

Lobectomy removes one lobe (section) of a lung, most often to treat lung cancer. More than 13,000 lobectomies were performed in the U.S. in 2019. [1][2]

Other thoracic procedures include:

• Heart valve repair or replacement, such as aortic valve replacement or mitral valve commissurotomy

• Aneurysm repair, including TEVAR for thoracic aortic aneurysm

• Surgery for heart rhythm problems

• Heart and lung transplants

• Removal of esophageal or thymus tumors

• Repair of a hiatal hernia or anti-reflux surgery for GERD

How do open and minimally invasive thoracic surgery differ?

Open thoracic surgery uses one larger incision, while minimally invasive surgery uses several small cuts, a tiny video camera and long, thin instruments. [1]

Feature	Open surgery	Minimally invasive surgery
Incision	One larger cut	Several small cuts
Access	Through the breastbone (sternotomy) or between the ribs (thoracotomy)	Camera and thin tools through small openings (VATS)
Robotic option	No	Yes; the surgeon controls the robotic arms at all times
Typical hospital stay	About a week	About 3 to 4 days
Full recovery	A month or more	A month or more

Some operations can be done with robotic assistance. The robot does not operate on its own; the surgeon guides every movement from a console. [1]

Your surgeon chooses the approach based on your condition, your overall health and the type of operation you need. [1]

How do you prepare for thoracic surgery?

Preparing for thoracic surgery starts with tests that show how well your heart and lungs work and how safely you can go through the operation. [1]

Common tests before surgery include:

Test	What it checks
Blood tests	General health, blood count, organ function
Heart imaging and rhythm tests	Heart structure, rhythm and pumping function
Chest imaging	The lungs and the area to be treated
Pulmonary function tests	How much air your lungs hold and move
Walking test	Your fitness level and risk of complications

Your care team will also ask you to:

• List every medicine you take, including over-the-counter drugs and supplements.

• Stop certain medicines (such as blood thinners) only as instructed.

• Quit tobacco at least one month before lung surgery.

• Follow the fasting instructions before the operation.

• Arrange a ride home and someone to help you for a few days.

• Prepare meals ahead so you can rest after discharge.

[1]

Staying active before surgery may also help. Exercise programs before lung surgery have been linked to fewer complications and shorter hospital stays. [6]

What happens during thoracic surgery?

During thoracic surgery, you are fully asleep under general anesthesia while the surgeon repairs, removes or replaces the affected part of the chest. [1]

The main steps are:

1. Anesthesia: Medicine is given through an IV line, and a breathing tube is placed.

2. Heart-lung machine (some operations): This machine takes over pumping and breathing during certain heart surgeries.

3. Access: The surgeon opens the chest through the breastbone, between the ribs, or through small keyhole cuts.

4. Repair: The diseased tissue is repaired, removed or replaced.

5. Closing: The surgeon checks for bleeding and closes the incisions.

[1]

What is recovery like after thoracic surgery?

Recovery after thoracic surgery usually means a hospital stay of 3 to 10 days, followed by a month or more of healing at home. [1]

Stage	What to expect
Right after surgery	You wake up in a recovery room or ICU; the breathing tube is removed
First hours to days	Chest drainage tubes and a urine catheter may stay in place for a short time
First days	Assisted walking and breathing exercises help re-expand the lungs
Day 3 to 10	Discharge home, depending on the operation
About 1 month	Driving may be allowed again; most people need a month or more to recover fully
About 6 weeks	Heavy-lifting limits usually end

[1]

Minimally invasive surgery often shortens the hospital stay to about 3 to 4 days. [1] Studies also link keyhole lung surgery to fewer complications than open surgery. [4][5]

What are the risks and benefits of thoracic surgery?

Thoracic surgery can save or extend life and improve how your heart, lungs or esophagus work, but like any major operation it carries risks. [1]

Benefits	Possible risks
Can save or extend life	Infection, including pneumonia
Improves heart function	Collapsed lung
Improves lung function	Blood clots
Eases daily problems such as swallowing	Abnormal heart rhythms
Removes tumors	Heart failure
	Fluid in the lungs (pulmonary edema)
	Depression

[1]

Your surgical team takes steps to lower these risks, such as early walking, breathing exercises and close monitoring. If a blood clot does form, treatments such as an embolectomy may be needed.

When should you call a doctor after thoracic surgery?

You should call your doctor or seek urgent care after thoracic surgery if you notice any of these signs: [1]

• Chest pain

• Shortness of breath

• Bleeding

• Fever

• Redness, swelling, drainage or opening at the incision

If chest pain or breathing trouble is severe or sudden, call your local emergency number right away.

Conclusion

Thoracic surgery covers a wide range of operations on the heart, lungs, esophagus and other chest organs. Modern keyhole and robotic techniques have made many of these operations easier to recover from, and preparing well, including staying active and quitting smoking, can make a real difference.

If you or a loved one is facing chest surgery, bring your questions to your surgeon and ask which approach fits your case. Read our related guides on coronary revascularization and aortic valve replacement, and learn how to check a thoracic surgeon's board certification before your consultation.
