Our Summary

This study evaluates a new technique for performing liver biopsies, specifically in patients for whom the procedure might be risky due to issues with blood clotting or fluid in the abdomen. Liver biopsies can sometimes lead to bleeding in about 10.9% cases. The new method involves using N-butyl cyanoacrylate, a type of glue that can quickly stop bleeding, even in critical situations.

The researchers tested this technique on 86 patients from 2014 to 2020, including 21 who were considered high-risk for traditional biopsy. The procedure involved first taking a liver sample with a needle, then injecting the N-butyl cyanoacrylate to seal the puncture route and prevent bleeding. They found that the new method was successful in all cases, with no complications, and the biopsies provided adequate samples for diagnosis.

It took an average of about 53 seconds to seal the puncture route, and the amount of radiation exposure to the skin was well below the level that might cause temporary redness. These findings suggest that this new technique could be a safer option for liver biopsies, particularly for high-risk patients.

Doctor’s Tip

A helpful tip a doctor might tell a patient about liver biopsy is to make sure to follow all pre-procedure instructions, such as fasting before the biopsy and avoiding certain medications that can increase the risk of bleeding. It is also important to inform the doctor of any allergies or medical conditions that may affect the procedure. After the biopsy, it is important to rest and avoid strenuous activities to allow the liver to heal properly. If any unusual symptoms such as severe pain, fever, or excessive bleeding occur after the biopsy, it is important to contact the doctor immediately.

Suitable For

Patients who are typically recommended for liver biopsy include those with:

  1. Liver disease, such as hepatitis or cirrhosis, to determine the extent of liver damage and guide treatment.
  2. Abnormal liver function tests, to diagnose the underlying cause of liver dysfunction.
  3. Suspicion of liver cancer, to confirm the diagnosis and determine the stage of the cancer.
  4. Evaluation of liver transplant candidates, to assess the health of the liver and determine if a transplant is necessary.
  5. Monitoring the progression of liver disease or the effectiveness of treatment.
  6. Unexplained liver abnormalities, such as jaundice or abnormal liver imaging findings.
  7. Suspected liver infections, such as hepatitis B or C, to confirm the diagnosis and guide treatment.
  8. Autoimmune liver diseases, such as autoimmune hepatitis or primary biliary cholangitis, to guide treatment.
  9. Suspected liver toxicity from medications or other substances, to confirm the diagnosis and guide management.
  10. Monitoring for potential complications of liver disease, such as liver fibrosis or cirrhosis.

Overall, liver biopsy is a valuable diagnostic tool that can provide important information about the health of the liver and guide treatment decisions.

Timeline

Before the liver biopsy:

  • Patient will undergo a physical examination and medical history review
  • Blood tests and imaging studies may be conducted to assess liver function and identify any abnormalities
  • Patient may be instructed to avoid food and drink for a certain period of time before the procedure
  • Patient may receive sedation or anesthesia to help relax and numb the area where the biopsy will be performed

During and after the liver biopsy:

  • The liver biopsy procedure involves inserting a thin needle into the liver to collect a small tissue sample
  • The patient may experience some discomfort or pain during the procedure
  • After the biopsy, the patient will be monitored for a period of time to check for any signs of bleeding or other complications
  • Patient may be advised to take it easy for a day or two following the procedure
  • Results of the biopsy will typically be available within a few days to a week, and the patient will meet with their healthcare provider to discuss the findings and any further treatment options.
