Our Summary
This research study looked at the effectiveness of a new, non-invasive method for diagnosing liver fibrosis, a disease that causes scarring of the liver. The traditional method for diagnosing liver fibrosis is through a liver biopsy, which involves taking a small sample of liver tissue. This new method, called two-dimensional shear wave elastography (2D-SWE), uses an ultrasound system to measure the stiffness of the liver, which can indicate the presence of fibrosis.
The study involved 108 adult patients with chronic liver disease. It found that 2D-SWE was a good method for diagnosing significant and severe fibrosis and excellent for diagnosing cirrhosis (an advanced stage of liver fibrosis). The results were similar to another non-invasive method called transient elastography (TE). This suggests that 2D-SWE could be used as part of the diagnostic process for chronic liver disease.
The study also provided specific values that indicate the presence of significant fibrosis, severe fibrosis, and cirrhosis when using 2D-SWE. This could help doctors in deciding the best course of treatment for their patients.

Doctor’s Tip
A helpful tip a doctor might give a patient about liver biopsy is to inform them about the potential risks and complications associated with the procedure. This could include bleeding, infection, and injury to surrounding organs. It is important for patients to follow any pre-procedure instructions provided by their healthcare provider, such as fasting or stopping certain medications. After the biopsy, patients should follow any post-procedure care instructions, such as avoiding heavy lifting and monitoring for signs of infection. It is also important for patients to communicate any concerns or symptoms they may experience after the biopsy to their healthcare provider.
Suitable For
Patients who are typically recommended for a liver biopsy include those with chronic liver disease, suspected liver fibrosis or cirrhosis, abnormal liver function tests, unexplained liver enzyme elevations, suspected liver tumors or masses, and monitoring of liver transplant recipients. Additionally, liver biopsy may be recommended for patients with autoimmune liver diseases, metabolic liver diseases, and certain viral infections such as hepatitis B or C. It is important for doctors to carefully consider the risks and benefits of a liver biopsy for each individual patient before proceeding with the procedure.
Timeline
Before the liver biopsy, a patient may undergo various tests and evaluations to determine the need for the procedure. This may include blood tests, imaging studies, and a physical examination. The patient may also be instructed to fast for a certain period of time before the procedure.
During the liver biopsy, the patient will be positioned on their back or side, and the healthcare provider will use ultrasound or a CT scan to locate the liver. Local anesthesia will be administered to numb the area where the biopsy needle will be inserted. The patient may feel a brief, sharp pain as the needle is inserted, but the procedure is generally well tolerated.
After the liver biopsy, the patient may be observed for a few hours to monitor for any complications such as bleeding or infection. The patient may experience some soreness or discomfort at the biopsy site, which can usually be managed with over-the-counter pain medication. The healthcare provider will provide specific instructions on how to care for the biopsy site and when to follow up for the results.
Overall, the liver biopsy process can provide valuable information about the extent of liver fibrosis and guide treatment decisions for patients with chronic liver disease. The introduction of non-invasive methods such as 2D-SWE may offer a less invasive alternative for diagnosing liver fibrosis and monitoring disease progression.
