On May 27, the magnet-assisted quick liver transplantation was jointly accomplished by the liver transplantation team of Department of Hepatobiliary Surgery and Surgery Dreamworks led by Professor Lyu Yi of the First Affiliated Hospital of Xi 'an Jiaotong University, in which the "anhepatic phase" of liver transplantation was significantly shortened from the international standard of 30-40 minutes to 9 minutes and 50 seconds, setting a new world record.

On May 14, 19 and 22, the liver transplantation team of Department of Hepatobiliary Surgery in our hospital has successively completed three magnet-assisted quick liver transplantations, which shortened the "anhepatic phase" to 24, 17 and 12 minutes, respectively.

After more than 10 years of unswerving exploration, research and breakthrough, the 4th-generation magnetic ring for vascular anastomosis developed by Surgery Dreamworks has been finally applied in clinical practice. The magnetic ring can be attached to the ends of the three resected veins and the veins of the liver graft. By using the magnetic force, the hepatic vein anastomosis and normal blood circulation can be rapidly achieved. In clinical practice, shortening the anhepatic phase to the greatest extent plays a significant role in reducing the incidence of perioperative complications and improving the prognosis of patients following liver transplantation. Shortening the length of "anhepatic phase" may minimize the harm of liver transplantation to the recipients, and effectively decrease the risk of tumor recurrence after liver transplantation for liver cancer patients.

The anastomosis of major hepatic vessels in the process of liver transplantation is currently being manually accomplished, and even experienced surgeons with high suture skills require approximately 30 minutes to accomplish it. The goal of this ambitious team is to shorten the "anhepatic phase" to 3-5 minutes and to promote the development of liver transplantation across the world.
