The world's first example!The simplified version of my country's completion process "ischemic" liver transplantation surgery

【Technological frontier】

Our newspaper, Beijing, August 15th (Reporter Jin Zhenya correspondent Zhu Wenhe and Zhou Ruiquan) At 21:00 on the 14th, the liver transplantation center of the China -Japan Friendship Hospital and He Xiaoshun team in the organ transplantation center of the First Affiliated Hospital of Sun Yat -sen University cooperated to successfully complete a 54 -year -old hepatitis B Liver transplantation surgery of male patients with cirrhosis. This surgery is the world's first process simplified version of the "ischemia -free" liver transplantation surgery, which simplifies the vascular sync process. The first time the liver obtaining process is shortened by about 30 minutes.

He Xiaoshun, deputy dean of the Special Professor of China -Japan Friendship Hospital, deputy dean of the First Affiliated Hospital of Sun Yat -sen University, and the leader of the Department of Organ Transplantation, introduced that the traditional liver transplantation surgery, once the liver leaves the donor, experienced in the state of "no blood flow supply", experienced The process of ischemia, cold preservation and re -injection may last for several hours or even tens of hours. Damage of liver function is often difficult to avoid. This is the main reason for affecting the efficacy of transplantation and even the failure of transplantation.

The "ischemia -free" liver transplant technology can effectively solve the problem of long -term liver in the liver. Tan Haidong, director of the liver transplantation center of the China -Japan Friendship Hospital, pointed out that the principle is to pick up the supply organs. The "multi -organ function repair system" of the vascular access to the original blood supply, while the "multi -organ function repair system" is replaced by the human blood supply mechanism. When the liver planting transplantation receptor, the blood vessels of the receptor are connected to the "multi -organ function repair system", and then the hemorrhage system of the receptor "takes care", and finally the liver transplantation is completed. Throughout the process, the blood flow in the liver is non -stop, and the postoperative liver function indicators are also significantly better than traditional liver transplant surgery. The survival rate of patients' perioperative surgery is increased by nearly 10%. Reduce to 5%.

Tan Haidong introduced that as early as 2017, He Xiaoshun's team performed the world's first "ischemia -free" liver transplant surgery. The original surgery was used to match the blood vessels and the arteries of the body, and the "ischemia -free" liver transplant surgery was used directly as the entrance to the entrance of the liver, which performed the door veins and the Y -shaped kiss, which greatly simplified the blood vessel The time to match the process, while ensuring that the liver has no ischemia, the "liver -free" time of the receptor is shortened to about two -thirds of the original, and the time for the obtaining liver is also shortened for about 30 minutes.

"The success of this example marks a new major breakthrough in the" ischemia -free "liver transplant surgery, which will provide a new basic research solution for research organs, organ interaction, organs ionizing treatment, and organ function restoration. It is possible that my country's clinical medical research to achieve multi -disciplinary and multi -level improvement. "Tan Haidong said.
