Lung Biopsy

A lung biopsy is a medical procedure that involves removing a small sample of tissue from the lungs for examination under a microscope. The purpose of the procedure is to diagnose and identify various lung conditions, such as lung cancer, infections, or inflammatory diseases.

Types of Lung Biopsy

• Open Lung Biopsy: This type of biopsy involves making an incision in the chest wall to access the lungs. It is usually performed under general anesthesia and requires a hospital stay.
• Video-Assisted Thoracic Surgery (VATS) Lung Biopsy: This minimally invasive procedure uses a small camera and surgical instruments inserted through tiny incisions in the chest wall to visualize and remove lung tissue.
• Needle Lung Biopsy: Also known as percutaneous needle biopsy, this procedure involves inserting a thin needle through the skin and into the lungs to collect tissue samples. It is usually performed under local anesthesia or sedation.
• Transbronchial Lung Biopsy: This type of biopsy involves passing a flexible tube with a camera and biopsy forceps through the mouth or nose and into the lungs to collect tissue samples.

Preparation for Lung Biopsy

Prior to the procedure, patients may be required to:

• Undergo imaging tests such as chest X-rays or CT scans to locate the area of interest in the lungs
• Stop taking certain medications that may increase bleeding risk, such as blood thinners
• Fast for a specified period before the procedure
• Remove any jewelry or metal objects that may interfere with medical equipment

Risks and Complications of Lung Biopsy

As with any invasive medical procedure, lung biopsy carries potential risks and complications, including:

• Bleeding or hemorrhage
• Infection
• Pneumothorax (collapsed lung)
• Air leaks from the lungs
• Damage to surrounding tissues or organs

Aftercare and Recovery

Following a lung biopsy, patients may experience:

• Chest pain or discomfort
• Shortness of breath
• Fatigue
• Bruising or swelling at the incision site (if applicable)

Patient recovery and aftercare instructions may include:

• Resting for a specified period
• Avoiding strenuous activities
• Taking pain medication as directed
• Following up with the doctor to review biopsy results and discuss further treatment options

Biopsy Results

The tissue samples collected during a lung biopsy are sent to a laboratory for examination under a microscope. The pathologist's report may take several days to several weeks to complete, depending on the complexity of the case.

The results may indicate:

• Benign (non-cancerous) conditions such as inflammation or infection
• Malignant (cancerous) tumors, including lung cancer subtypes
• Other conditions such as interstitial lung disease or pulmonary fibrosis
