The liver has an excellent characteristic: it is the only human organ capable of "re-growing." This is of great benefit, for example in case of cancerous activity. However, how much of the liver can be removed without risking liver failure depends on the functioning of organ. With the liver function test, the hepatic function can be tested, and the operation planned precisely.
In which diseases is a partial removal of the liver necessary?
The most common cause is liver metastasis, i.e., offspring of a tumor in the liver. Less common are primary forms of cancer that originate from the liver, namely bile duct cancer and hepatocellular carcinoma. They usually occur in organs that are already damaged, often by chronic liver cell inflammation (hepatitis) or long-term alcohol consumption.
Also, there are benign diseases such as liver cysts or hemangiomas. These can become so large that they press on surrounding organs such as the stomach and need to be operated on. To get rid of them, one must know about LFT test cost to spend a healthy lifestyle.
Why is it essential to test their function before partial liver removal?
In contrast to the large intestine, where it is less critical to remove 5 centimeters, more or less, one can remove too much from a liver. If this is the case, the patient has hepatic hypofunction and often needs to know about Liver Function Test cost in Delhi.
How much liver does a person need?
That depends on their functionality, which makes the use of the test so exciting and useful. About 75 percent can be removed from a completely healthy liver. Hepatic cells show specific pathological changes, be it a slight fatty degeneration, liver inflammation, liver fibrosis (remodeling of liver tissue in connective tissue) or even liver cirrhosis (liver shrinkage). The sicker the liver is, the less it performs and the less the surgeon may remove. LFT Test cost in Delhi can help you in determining the severity of the disease.
How does the test work?
The patient is injected with a volume-adjusted amount of the drug 13C-methacetin via a vein. This remedy then "floats" on the liver, which metabolizes it. Functioning liver cells convert this drug into paracetamol and 13CO2 relatively quickly. The 13CO2 is released and measured again via the breathing air. The device displays this on a graph. Once the maximum is reached, the test can be stopped. The test usually takes 30 to 40 minutes. With cirrhosis of the liver, it can last up to an hour, and the curve can be quite flat, as the liver has far more trouble metabolizing the drug.
In which cases do you have high liver function values?
In metastasis surgery, this often applies, that is, if it is offspring of another tumor in the liver. Often the liver function is still so intact that you can remove about three-quarters of the liver. By contrast, in primary liver cancer, the role of the liver is usually so limited that surgery is no longer possible and only drug therapies or alternative therapies can be used.
