Techniques, Indications, Contraindications, and Complications of Liver Biopsy

Techniques, Indications, Contraindications, and Complications of Liver Biopsy

Percutaneous liver biopsy is a technique whereby a needle is inserted through the skin, into the liver, to obtain a sample of tissue for histopathological examination in order to diagnose and grade any liver abnormality. The sample is usually obtained under the guidance of ultrasonography, CT scan, or MRI. Liver biopsy can also be taken via laparoscopy; however, percutaneous route is less invasive and less costly. Indications of liver biopsy are: -further evaluation of abnormal liver function test -to distinguish between non-alcoholic fatty liver disease and non-alcoholic steatohepatitis -fever of unknown origin to rule out possible cause such as tuberculosis and histoplasmosis -autoimmune hepatitis -drug-induced liver injury -post-liver transplant rejection -grading of chronic hepatitis B and C -fibrosis -hemochromatosis Liver biopsy is contraindicated in certain conditions. These are: -non-compliant patient -thrombocytopenia or coagulopathy -suspected vascular tumor -NSAID use within last 7 days -ascites -extrahepatic biliary obstruction Liver biopsy is generally a safe procedure. Rare complications are: -hypotension secondary to hemorrhage or vasovagal response -hemobilia -hemothorax -pneumothorax -portal vein thrombosis -transient bacteremia -biliary peritonitis -subphrenic abscess -death Reference: https://www.ncbi.nlm.nih.gov/books/NBK553146/ Video courtesy: https://www.youtube.com/watch?v=bFlJVosYfXM

I was diagnosed as a Hepatitis B carrier in 2015, with early signs of liver fibrosis. At first, antiviral medications helped control the virus but over time, resistance developed, and the effectiveness faded. I began to lose hope. In 2021, I discovered NaturePath Herbal Clinic despite my skepticism, I decided to give their herbal treatment a try.To my surprise, after just six months, my blood tests came back negative for the virus.It was nothing short of life-changing.I never expected such incredible results from a natural treatment. But it not only cleared the virus it restored my hope, my health, and my peace of mind.If you or someone you know is battling Hepatitis B, I truly encourage you to explore the natural healing path offered by NaturePath Herbal Clinic. It gave me a second chance and it might do the same for you.www.naturepathherbalclinic.com info@naturepathherbalclinic.com
