Liver biopsy
Liver Biopsy
A Liver Biopsy (/ˈlaɪvər baɪˈɒpsi/) is a medical procedure that involves the removal of a small piece of liver tissue, which is then examined under a microscope to detect any abnormalities or diseases.
Etymology
The term "Liver Biopsy" is derived from the Greek words "hepar" or "hepato-" meaning liver, and "opsis" meaning view or sight. The term "biopsy" was first used in the 19th century and is a combination of the Greek words "bios" (life) and "opsis" (view).
Procedure
A Liver Biopsy is usually performed by a hepatologist or a radiologist. The procedure involves inserting a needle through the skin and into the liver to extract a small tissue sample. This sample is then sent to a pathology lab for examination.
There are three main types of Liver Biopsy procedures: percutaneous, transjugular, and laparoscopic.
- Percutaneous Liver Biopsy: This is the most common type of liver biopsy. The doctor inserts a needle through the skin and into the liver to remove a small piece of tissue.
- Transjugular Liver Biopsy: In this procedure, the doctor inserts a needle into a vein in the neck and guides it to the liver. This method is used when patients have blood clotting problems or excess fluid in the abdomen.
- Laparoscopic Liver Biopsy: This procedure involves making a small incision in the abdomen and inserting a special instrument called a laparoscope to remove the liver tissue.
Risks and Complications
Like any medical procedure, a Liver Biopsy carries some risks. These may include pain, bleeding, infection, and injury to other organs. In rare cases, a liver biopsy can lead to life-threatening complications.
