Recently, “woman to save her ex-husband with liver cancer, liver donation and remarriage”, “three filial sons competing to give their cancer-stricken father a liver donation” and so on, news reports are endless, spreading positive energy at the same time let us familiar with a word “liver transplantation! “LIVER EXCHANGE The so-called liver transplant is a living liver transplant. The people don’t understand what it means, for example, what is a living donor liver transplant? Today, we will lead you to explore the related issues. What are the functions of the liver? Is it possible to replace the liver? Metabolic function: ① sugar metabolism ② protein metabolism ③ fat metabolism ④ vitamin metabolism ⑤ hormone metabolism Immune function: liver is the largest reticuloendothelial phagocytosis system, which can be phagocytosed ﹑ isolation and elimination of invasive and endogenous antigens. Coagulation function: almost all coagulation factors are produced by the liver, and the liver plays an important role in regulating the dynamic balance of coagulation and anticoagulation systems. The severity of liver function destruction is often parallel to the degree of coagulation disorder, and it is common to see some cirrhotic animals bleeding or even dying due to liver function failure. Others: Liver is involved in the regulation of blood volume, heat production and water and electrolyte regulation. If the liver damage to sodium, potassium, iron, phosphorus, and other electrolyte regulation imbalance, commonly water and sodium retention in the body, causing edema, ascites and so on. The liver has so many important functions, can it be exchanged for someone else? A healthy liver has great potential functions. Under normal circumstances, 70% of the liver can be removed without causing liver failure. Moreover, the doctor will choose the most suitable transplantation ratio according to the actual situation before the surgery, and usually the remaining 30% or more is safe for the donor. Meanwhile, liver has strong regeneration ability, although it cannot heal itself in a second like Wolverine, it has been reported in the literature that liver regeneration occurs in living donor liver transplantation between 2 weeks and 1 month after the operation, and the liver can reach 90% of its preoperative volume in 3 months after the operation. Of course, liver regeneration is a proliferation of the remaining portion of the liver, not a regeneration of the resected area, so the shape of the regenerated liver will be different from that of the pre-operative liver. Therefore, “liver transplantation” is possible. Okay, so that’s it. Who can donate a liver? 1. age less than or equal to 50 years old; 2. ABO blood type; 3. liver shape, texture, function is normal, no history of hepatitis and other chronic liver diseases, no fatty liver; sometimes in the extreme lack of liver sources, also have to use the liver does not meet the criteria, such as mild to moderate fatty liver patients, the elderly liver. 4. no other factors that may affect the liver. 4. no other diseases that may affect liver function, such as arteriosclerosis, hypertension, and no history of alcoholism; 5. no malignant tumors, tuberculosis, systemic or localized septic infections, and no viruses or other pathogens, such as HIV and rabies. To summarize, it is possible to continue to live with a part of the liver cut off. If it is good, it can gradually recover to the health condition before donation.
