Our Summary

The research examines a new way to diagnose lung issues using a tool known as a cryoprobe, which is used along with two other procedures. The study involved 110 patients from April to November 2021 who were having a particular type of lung scan for smaller lung issues (30mm or less).

They found that using the cryoprobe along with the two existing procedures was better at diagnosing these lung issues than using the existing procedures alone. The cryoprobe also gathered larger samples of tissue for testing than the other tools. They found that the cryoprobe was particularly helpful in diagnosing smaller lung issues (22mm or less).

While there were some complications, such as a collapsed lung, infection, and significant bleeding, none of these were life-threatening and occurred in just over 1 in 10 patients.

Overall, the study concludes that using the cryoprobe along with the other tools can help improve diagnosing lung issues without causing serious complications.

Doctor’s Tip

A helpful tip a doctor might tell a patient about lung biopsy is to discuss the procedure thoroughly with your healthcare provider beforehand. Make sure to ask about the risks, benefits, and potential complications associated with the biopsy. It is important to follow any pre-procedure instructions provided by your doctor, such as fasting or medication adjustments. After the biopsy, be sure to follow your doctor’s post-procedure care instructions carefully to promote healing and minimize complications. If you experience any concerning symptoms after the biopsy, such as persistent pain, difficulty breathing, or fever, contact your healthcare provider immediately.

Suitable For

Patients who are typically recommended for a lung biopsy include those with:

  • Suspicious lung nodules or masses
  • Suspected lung cancer
  • Interstitial lung disease
  • Pulmonary infections
  • Lung fibrosis
  • Lung inflammation
  • Lung lesions of unknown origin

The study mentioned above specifically focused on patients with smaller lung issues, but lung biopsies can be recommended for a variety of lung conditions depending on the individual patient’s symptoms and medical history.

Timeline

Before the lung biopsy:

  1. Patient undergoes initial consultation with their healthcare provider to discuss symptoms and potential need for a lung biopsy.
  2. Imaging tests such as X-rays or CT scans are conducted to identify the location and size of the lung issue.
  3. Patient may undergo blood tests and other diagnostic procedures to assess their overall health and suitability for the biopsy.
  4. Patient receives instructions on pre-biopsy preparations such as fasting and medication adjustments.

During the lung biopsy:

  1. Patient is prepped for the procedure and given anesthesia to numb the area.
  2. Biopsy tool, such as a cryoprobe, is inserted through the skin and into the lung to collect tissue samples.
  3. Patient may experience minimal discomfort or pressure during the procedure.
  4. Tissue samples are collected and sent to a lab for analysis.

After the lung biopsy:

  1. Patient is monitored for a period of time to ensure no immediate complications arise.
  2. Patient may experience some pain, soreness, or discomfort at the biopsy site.
  3. Results of the biopsy are typically available within a few days to a week.
  4. Patient follows up with their healthcare provider to discuss the biopsy results and determine further treatment options based on the findings.
