A thoracotomy is a surgical incision through the chest wall to access the lungs, heart, esophagus, or other structures inside the chest cavity. It is one of the larger operations in surgery, requiring general anesthesia and a recovery period of several weeks. Surgeons perform thoracotomies when they need direct, hands-on access to organs that can’t be adequately reached through smaller, camera-guided approaches.
Why a Thoracotomy Is Performed
The most common reason for a thoracotomy is lung cancer. When a tumor needs to be removed along with surrounding tissue, an open incision gives the surgeon the widest view and the most room to work. But cancer isn’t the only reason. Thoracotomies are also used to treat a collapsed lung, fluid buildup around the lungs or heart, problems with the diaphragm, esophageal diseases including esophageal cancer, and heart or blood vessel injuries from trauma.
In some cases, a surgeon plans to use a minimally invasive approach but encounters scar tissue or unexpected anatomy that makes the smaller operation unsafe. When that happens, they convert to an open thoracotomy during the procedure.
Types of Thoracotomy Incisions
Not every thoracotomy looks the same. The location and length of the incision depend on which organ the surgeon needs to reach and how much access they need.
A posterolateral thoracotomy is the most traditional approach. The incision curves from the back around to the side of the chest, and you’re positioned lying on your side. This gives the surgeon the broadest access to the lung and surrounding structures, making it the standard choice for major lung resections.
An anterolateral thoracotomy uses an incision on the front and side of the chest. It comes in two variations depending on whether the cut is made above or below the breast. This approach is often used in emergency and trauma settings because it can be performed quickly while you’re lying mostly on your back, with the operated side elevated about 30 to 45 degrees.
A muscle-sparing thoracotomy is designed to minimize damage to the chest wall muscles. Instead of cutting through the large muscles, the surgeon separates and moves them aside. You’re positioned on your side, similar to the posterolateral approach. Because fewer muscles are cut, this version tends to cause less post-operative pain and preserve more shoulder function during recovery.
How to Prepare
If you smoke, you’ll be asked to stop immediately. This isn’t a suggestion. Smoking dramatically increases your risk of breathing complications after chest surgery, and even a few days of abstinence before the operation helps your lungs clear mucus and recover faster afterward.
You’ll have a pre-surgery appointment that includes blood work and other tests to make sure your heart and lungs can handle the procedure. Bring a complete list of every medication you take, including over-the-counter drugs, vitamins, and supplements. Blood thinners typically need to be stopped about five days before surgery. If you develop a cold or flu in the days leading up to your operation, call your surgeon’s office because the procedure may need to be rescheduled.
What Happens During the Procedure
You’ll be under general anesthesia for the entire operation, so you won’t feel or remember anything. In many cases, the anesthesiologist uses a special breathing tube that allows them to deflate the lung being operated on, giving the surgeon a clear field to work in while your other lung keeps you breathing.
Once you’re positioned and asleep, the surgeon makes the incision, spreads the ribs apart using a retractor, and works directly on the affected organ. Depending on the reason for surgery, the procedure could take anywhere from one to several hours. Before closing, the surgeon places one or more chest tubes to drain fluid and air that collect in the chest cavity after the operation.
Recovery After Surgery
Most people spend several days in the hospital after a thoracotomy, often starting in an intensive care unit for close monitoring. The chest tubes stay in place until fluid output drops and any air leaks have stopped. At most centers, tubes are removed once drainage falls below about 350 to 400 milliliters over 24 hours and no significant air leak is detected for at least 12 hours.
Pain management is a major focus of early recovery. The incision cuts through skin, muscle, and the tissue between your ribs, all of which are rich in nerves. You’ll likely have an epidural catheter or nerve block in addition to other pain medications for the first few days. Breathing deeply and coughing will hurt, but it’s essential. A respiratory therapist will work with you on breathing exercises and incentive spirometry to keep your lungs expanding fully and prevent mucus from settling in your airways.
Once home, most people need six to eight weeks before they can return to normal activities. Lifting, pushing, and pulling are restricted during that time to protect the healing incision and ribs. Walking is encouraged early and often, starting in the hospital, because it helps prevent blood clots and keeps your lungs working well.
Risks and Complications
Thoracotomy is a major operation, and complications are not uncommon. Respiratory problems, including areas of collapsed lung tissue, pneumonia, and breathing difficulty, occur in 15 to 20% of patients. These complications account for most of the expected 3 to 4% mortality rate associated with the procedure. Bronchospasm, where the airways tighten and cause wheezing and shortness of breath, can also happen in the days after surgery.
Heart-related complications, mostly irregular heart rhythms, affect 10 to 15% of thoracic surgery patients. Blood clots in the legs or lungs are less common but potentially serious, occurring in roughly 1 to 2% of patients undergoing thoracic surgery for lung disease.
One of the rarer but most dangerous complications is fluid buildup in the remaining lung tissue after a portion of lung has been removed. This form of non-cardiac pulmonary edema carries a mortality rate above 50% when it occurs, though it is uncommon.
Chronic Pain After Thoracotomy
Pain that lingers long after the incision has healed is common enough to have its own name: post-thoracotomy pain syndrome. About 29% of patients report ongoing chest wall pain months or years after surgery. For most, the pain is mild. Roughly 13% rate their pain above a 3 on a 10-point scale, and fewer than 5% experience pain above a 5. The pain is often neuropathic, meaning it comes from nerve damage sustained during the operation rather than from ongoing tissue injury. It can feel like burning, tingling, or shooting sensations along the incision or between the ribs.
Thoracotomy vs. Minimally Invasive Surgery
For many of the same conditions treated by thoracotomy, surgeons now offer video-assisted thoracoscopic surgery (VATS). Instead of a large incision, VATS uses a few small cuts and a camera to guide the operation. Compared to open thoracotomy, VATS results in smaller incisions, less post-operative pain, fewer complications, and shorter hospital stays.
Not everyone is a candidate for the minimally invasive route, though. Large tumors, tumors in difficult locations, extensive scarring from previous surgeries or infections, and emergency situations all favor an open thoracotomy. The decision between the two depends on the specific problem being treated, the anatomy involved, and the surgeon’s experience with each approach.
