Indication of liver transplantation
**Core Concept**
Liver transplantation is a life-saving surgical procedure for patients with end-stage liver disease. It involves replacing the diseased liver with a healthy one, either from a donor or through a living donor. The indication for liver transplantation is crucial in selecting patients who will benefit from this procedure.
**Why the Correct Answer is Right**
Liver transplantation is indicated in patients with end-stage liver disease, such as those with cirrhosis, liver failure, or hepatocellular carcinoma. The liver's inability to perform its primary functions, including detoxification, protein synthesis, and metabolism, leads to the accumulation of toxins, coagulopathy, and other complications. Liver transplantation restores liver function, improves survival, and enhances quality of life. The Model for End-Stage Liver Disease (MELD) score is used to prioritize patients for liver transplantation based on the severity of their liver disease.
**Why Each Wrong Option is Incorrect**
**Option A:** Acute liver failure due to viral hepatitis is a possible indication for liver transplantation, but it is not the only option. **Option B:** Metabolic disorders, such as Wilson's disease or primary biliary cholangitis, may require liver transplantation, but they are not the primary indication. **Option C:** Liver cancer, such as hepatocellular carcinoma, is a common indication for liver transplantation, especially in patients with cirrhosis.
**Clinical Pearl / High-Yield Fact**
It is essential to note that liver transplantation is not a cure for liver disease, but rather a treatment to replace the diseased liver. The success of liver transplantation depends on various factors, including the patient's overall health, the availability of a suitable donor organ, and the absence of contraindications.
**Correct Answer:** C.
