lung biopsy is a surgical procedure to extract a small amount of lung tissue for examination under a microscope, which is held in the case kakih-libo pathological changes in the lungs, near the light, orchest.Most often, the procedure is performed to eliminate lung cancer.Usually biopsy is appointed only after the pathology detected on chest radiograph or CT scan.
Today biopsy can be done in 4 ways.The choice of the method used depends on the overall health of the patient and the area for biopsy.
How to prepare for lung biopsy
Before lung needle biopsy, patients are usually recommended to abstain from the consumption of food and liquids for 6-12 hours before the procedure.Also, it is recommended for some time to refrain from biopsy nonsteroidal anti-inflammatory drugs such as ibuprofen and blood thinning drugs such as warfarin or aspirin.
You should inform your doctor:
- If you are pregnant
- You are allergic to any drugs
- You have a bleeding disorder
- You should tell the doctor about all medications that are taking (including any herbal preparations).
Before biopsy can be performed X-ray or CT scan of the chest, the doctor may prescribe a complete blood count.
Sometimes sedative before the procedure appointed sedation, the patient can relax.
During the biopsy is important to remain as still as possible and to avoid coughing.
clinics usually practiced by the signing of the patient informed consent form, which means that you are familiar with all the possible risks and complications that may arise during the procedure.
biopsy may be performed during bronchoscopy or mediastinoscopy.This method is used in cases of suspected communicable diseases and location of abnormal lung tissue near the bronchi.
During bronchoscopy a narrow tube - a bronchoscope inserted through the mouth or nose into the respiratory tract.Bronchoscopy is also used for diagnostics, such as pulmonary cancer, and for assessing pulmonary symptoms such as chronic cough, hemoptysis.
During bronchoscopy, doctors can visualize the surface of the respiratory tract, as well as to take a biopsy of any area where the detected abnormal tissue.
Bronchoscopy using a bronchoscope usually takes 30 to 60 minutes.After the procedure, the patient needs is likely to remain in the recovery room 1 - 2 hours.
After treatment, the patient may experience some dry mouth for several hours as well as sore throat and hoarseness light.Lozenges or gargle with warm salt water can help eliminate help help alleviate this state very quickly.
Percutaneous needle biopsy (or transthoracic needle aspiration biopsy)
lung needle biopsy of lung - sighting puncture the lung tissue pathological section in order to obtain cell samples of lung tissue.It is performed by means of a long needle introduced through the thorax.This method is used when the pathological lung tissue located close to the chest wall.
puncture lung biopsy performed under ultrasound or x-ray control, it can also be used chest CT.
If a biopsy is performed under CT guidance, the patient lies during the procedure.procedure is performed in a sitting position in all other cases.Under the skin is injected local anesthetic drug (anesthetic).
patient should try to sit still, not to cough during the biopsy, and hold your breath for a while.The doctor makes a small (about 4 mm) incision and the needle punctures the tumor or abnormal lung tissue, then removed a small piece of cloth, and sent to a laboratory for analysis.Place the cut is pressed to stop the bleeding and it imposed tight bandage.
very important not to move and not to cough during the procedure.
Immediately after biopsy do chest X-ray.The procedure usually takes 30 - 60 minutes, then you will need to stay in the recovery room 1 - 2 h.
Laboratory analysis usually takes a few days.
What do you feel during the biopsy
As already mentioned, you will make the injection of anesthetic before the biopsy.During the injection you will feel a sense of light burning for a moment.
During the procedure you will have a feeling of light pressure, and you'll feel a short sharp pain when the needle for light.
open lung biopsy
open lung biopsy - surgery, during which the removal of a small piece of tissue from the lungs through an incision in the lungs.The sample is then examined for cancer, infections and lung disease.
This method is used if necessary for the diagnosis of most of the lung tissue.Also, this procedure can help diagnose a number of different diseases, such as:
- Rheumatoid lung disease
- Wegener's granulomatosis.
open lung biopsy is performed in a hospital operating room under general anesthesia, ie,you sleep and not feel pain.Through the mouth into the airway tube is placed, which leads to the lungs.
After treatment of the skin, the surgeon makes an incision between the ribs in the chest, and removes a small piece of lung tissue.The incision may be left chest tube for 1-2 days to prevent the light from being destroyed.It is removed when the drainage stops, the stitches are removed after 7 - 14 days.On the wound closed with stitches.
The entire procedure usually takes about an hour, after which the patient is left in the recovery room for about 1-2 hours.
What do you feel during the procedure
When you wake up after the procedure, you will be drowsy for several hours.You may have a slight sore throat from the tube.You will feel some pain and discomfort at the biopsy site, as well as fatigue within 1-2 days, muscle pain or sore throat.
lozenges or throat by gargling with warm salt water can help relieve the pain.
Today, most centers use a technique called Videothoracoscopy.It is performed using a tiny camera and instruments to biopsy the lung.
Using this method is only 2 small incision.The patient feels much less pain and recovery is much faster.
Explanation biopsy indicators
normal rate of lung tissue:
- lungs and lung tissue normally
- No growth of bacteria, viruses and fungi.
- symptoms of infection, inflammation or cancer have been identified.
abnormal rates of lung tissue are:
- The presence of bacterial, viral or fungal infection in the lungs
- Cancerous cells (lung cancer, mesothelioma)
- Outbreaks pneumonia
tumors - Diseases of the lungs (fibrosis)
- lung Cancer: causes, symptoms, stages, treatment
- Bronchitis: causes, symptoms, diagnosis, treatment, prevention
- complex of therapeutic exercises in bronchial asthma
- complex of therapeutic exercises with emphysema, bronchitis, chronic pneumonia
- transplant (transplant) light
Risks and complications after
biopsy after biopsy Sometimes it may be a collapsed lung (pneumothorax).To check this, you need to make an X-ray light.
Signs of lung collapse include:
- Blue skin
- Chest pain
- Increased heart rate (pulse)
- Shortness of breath
If there is any of these symptoms, report them immediately to the doctor.
Typically, a collapsed lung after a biopsy does not need treatment.However, if the pneumothorax is extensive and there are improvements in chest drainage tube is inserted through which air escapes, and easy crushes.
In rare cases, pneumothorax can be life-threatening, if the air leaves the lungs and does not find a way out of his chest, he falls into the trap, and begins to put pressure on the lungs or heart.
increases the risk of you have certain lung diseases such as emphysema.
Whenever biopsy have the risk of excessive bleeding (hemorrhage).Minor bleeding is common during the procedure, and the physician should monitor blood loss.The extensive and life-threatening bleeding events are rare.
Contraindications to lung biopsy
biopsy should not be performed if other tests show that you have:
- Any violation
clotting - Emphysema
- Cysts light
- Pulmonary hypertension
- Severe hypoxia(low oxygen content in the blood)
- Heart failure.
