British researchers reported on March 15 that they developed a device that mimics the living environment of the liver in which the liver can survive for 24 hours. This result has won more time for liver transplant surgery and helps to improve the success rate of transplantation.
Researchers at the University of Oxford said at the press conference that day that the new device they developed would provide the liver with an environment similar to the survival of the body, including infusing it with oxygenated red blood cells, providing various nutrients and maintaining close to body temperature. The temperature and so on. After 30 seconds of switching on the device, the liver removed from the donor began to return to normal color, and the functions of secreting bile remained normal. Experiments have shown that the liver can survive in new devices for up to 24 hours.
According to reports, in the liver transplantation process, the liver can only be cooled by ice to reduce its metabolism, but this process often causes liver damage and can only be stored for several hours. Since the liver to be transplanted has to undergo various examination tests, a certain treatment is required for the patient undergoing transplantation to enter the state of accepting the new liver, so it is important to extend the preservation time after the liver is taken out, which is very important for successful transplantation.
The King's College Hospital used the new device in two liver transplants in February this year, and the two patients undergoing surgery are currently recovering well. Nigel Heath, director of the transplant surgery at the hospital, said that winning time for transplants means that the chances of survival after surgery are increased. If the new device is widely used in liver transplants, it will bring this field Positive change.
In an interview with Xinhua News Agency, one of the inventors of the new installation, Professor Konstantin Cosios of Oxford University, said that this is the first automatic device to prolong the survival time in vitro by simulating the living environment of the liver. More livers are suitable for transplant surgery, and there have been no major technological breakthroughs in liver transplant surgery for decades.
According to reports, in Europe and the United States, about 30,000 patients await liver transplantation each year, and about a quarter of them die because they cannot wait for a suitable liver. At the same time, about 2,000 livers are damaged each year during the transplant process and cannot be used.
