What is thoracoscopy?

Thoracoscopy is a procedure that uses a thin tube with a light and camera, called a thoracoscope, inserted through a small incision. This procedure lets your doctor see inside your chest to take biopsies, perform procedures or carry out surgery.

Thoracoscopy is common in the care of lung conditions, especially lung cancer. If you have lung cancer symptoms, this procedure can help your care team take a closer look without the need for more invasive surgery.

Why is a thoracoscopy performed?

​​​​​​​​​​​​​Thoracoscopy helps diagnose and treat conditions in the chest. Sometimes, thoracoscopy is needed as a follow-up procedure when your care team sees an abnormal spot or nodule on an imaging test. By taking samples during a thoracoscopy, your team can determine the cause of any symptoms. If you’ve already been diagnosed, thoracoscopy can also be a minimally invasive option for treatment.

For diagnosis

When the cause of your symptoms isn’t clear, thoracoscopy gives your care team a way to see inside your chest visually. During thoracoscopy, your doctor can also take samples, called biopsies, to diagnose cancers that affect the chest, including mesothelioma, esophageal cancer and lung cancer.

The procedure is also helpful in staging lung cancer. It gives your care team more information about the cancer’s size, location and if it has spread.

For treatment

Thoracoscopy is an option for treating some lung, esophagus, and thymus gland conditions, including cancer or fluid buildup. During thoracoscopy, your doctor can insert additional tools for surgery or other procedures.

  • Treating lung cancer: When lung cancer is still small and localized, it may be treated during a thoracoscopy. Your doctor can remove a wedge of tissue from your lung where the tumor is located or an entire lobe of your lung, called a lobectomy.
  • Drain fluid around your lungs: Excess fluid buildup around your lungs can make it hard to breathe. Your doctor may drain this fluid during a thoracoscopy. Fluid drainage performed without thoracoscopy is called thoracentesis.
  • Help prevent fluid buildup in the chest: When fluid continues to build up around the lungs, your care team can perform pleurodesis. This procedure removes the space between the outer lining around the lungs and the chest wall so fluid can no longer build up.
  • Repair a collapsed lung: Some cases of pneumothorax, or a collapsed lung, are treated using a thoracoscopy procedure.

Video-assisted thoracoscopic surgery (VATS)

Video-assisted thoracoscopic surgery, known as VATS, is a minimally invasive thoracic surgery that uses a few small incisions. A thoracoscope and specialized tools are inserted through these small incisions to perform surgery. This surgery gives your care team an alternative to more invasive procedures and allows them to treat conditions in the chest.

Lung cancer is one of the main conditions treated with VATS. During the procedure, your doctor may take tissue samples in the lungs or nearby lymph nodes or surgically remove the part of the lung affected by cancer. Sometimes, VATS is an option for conditions outside the lungs, including esophagus or thymus cancer.

Thoracoscopy vs thoracotomy

Thoracoscopy is a minimally invasive procedure that uses small incisions, while thoracotomy is a traditional open surgical procedure that uses a larger incision. Your team can use both thoracoscopy and thoracotomy to treat a range of lung, esophagus and chest conditions. However, the right procedure depends on your condition and treatment goals.

Compared to thoracotomy, minimally invasive thoracoscopy offers several benefits, such as faster recovery and less pain.

Preparing for thoracoscopy surgery

Your care team will give you specific steps to prepare for your thoracoscopy. Before your surgery, your doctor will review your medical history, discuss any conditions affecting your care and schedule any needed pre-operative testing. Be sure to ask any questions about preparing for thoracoscopy and let your doctor know about your medical conditions and medications.

Some of the ways you’ll be asked to prepare leading up to your thoracoscopy include:

  • Quitting smoking
  • Stopping specific medications, including blood thinners or non-steroidal anti-inflammatory drugs
  • Adding daily exercise to your routine
  • Practicing deep breathing and using an incentive spirometer (a machine to improve lung strength)
  • Making plans for a caregiver who can drive you home from the hospital

What to expect with a thoracoscopy

​​​​​​​​​​​​​

Thoracoscopy may be either an outpatient procedure—meaning you go home the same day—or an inpatient procedure—when you’ll need to stay in the hospital. The length of time depends on the procedure or surgery your doctor performs. You’ll either have general anesthesia to make you sleep during your thoracoscopy or local anesthesia and medication to help you relax. Most thoracoscopy procedures take anywhere from 60 minutes to several hours.

Before the procedure

Before your procedure, it’s important to eat and drink as directed by your care team. When you arrive for your thoracoscopy, you’ll go to the pre-procedure area, where you’ll get an IV and have monitors placed on your body. You’ll also have a chance to talk with the anesthesiology provider and ask any questions.

During the procedure

If your thoracoscopy requires general anesthesia, you’ll have a breathing tube placed in the operating room. Then, your surgeon will make small incisions between two ribs just below your shoulder blade and near the underarm. A thoracoscope and tools are inserted to allow your surgeon to view the area and perform your specific procedure.

Depending on your procedure, you may have other additional small incisions made, your lung may be temporarily deflated, and a drain may be inserted to drain fluid. Once your procedure or surgery is complete, the small incisions are closed, the breathing tube is removed, and you’ll be moved to the recovery area.

After the procedure

Immediately after your thoracoscopy, you’ll still have several monitors or tubes attached to your body, and you may feel groggy. Your care team will monitor you in the recovery area before you are discharged or moved to your hospital room. It’s also common to have a chest X-ray as a follow-up to your procedure.

You can expect to stay a few days if your procedure requires a hospital stay. During your stay, your care team will work with you to manage pain, get you moving and teach you how to care for yourself when you go home.

Once you are home, be sure to follow your doctor’s instructions about pain management, caring for your incision and activity restrictions. If you had biopsies taken during your thoracoscopy, expect it to take a few days to get the results.

Risks and complications of thoracoscopy surgery

As thoracoscopy is a minimally invasive option, it tends to have fewer risks of complications than more invasive open surgical procedures. However, as with any procedure, there are some possible risks. Before a thoracoscopy, your doctor will help you understand the benefits and the risks of choosing this procedure.

Frequently asked questions

  • What can thoracoscopy detect?

    When used for diagnosis, a thoracoscopy can detect conditions that affect the lungs, esophagus, tissue around the lungs and thymus gland. It’s commonly used to look for signs of cancer and take biopsies to make a cancer diagnosis.

  • How long does it take to recover from a thoracoscopy?

    Most people resume daily activities within one or two weeks after their thoracoscopy. However, it may take up to four to six weeks to return to yourself. As thoracoscopy is a minimally invasive procedure, the recovery is usually shorter than traditional surgery.

  • How long does a thoracoscopy take?

    A thoracoscopy typically takes between 30 to 90 minutes. However, depending on your procedure, it could take several hours. For example, multiple biopsies can add to your procedure time. Your care team will let you know what to expect.

  • Is thoracoscopy painful?

    You may have pain around the incisions used during a thoracoscopy. But this pain typically gets better within a couple of weeks. Your care team will work with you to manage your pain and help you stay comfortable.

  • Is thoracoscopy a major surgery?

    No. Thoracoscopy isn’t a major open surgery. It uses small incisions and a scope, so it’s considered a minimally invasive procedure. While your doctor can perform surgery as a part of your thoracoscopy, some thoracoscopy procedures are used for diagnosis only, not surgery.
