The liver had a complicated pipeline system, which included the hepatic artery, portal vein, inferior vena cava, and biliary system.
Any doctor who could play with any of these systems would be able to make a name for himself in a regional hospital.
Of course, to be world-class or even second-class, it was definitely not enough to just play with one system. One system had to be world-class. Other systems also had second-class standards, only then could they fly around the world. Otherwise, if they went to a few hospitals and the local doctors did not give them face, they would not be able to continue playing transnational medical treatment.
Among them, the reconstruction of the hepatic portal vein could be said to be complicated and complicated. Naturally, people like Stephen or NARRAPAT could also do it, but if they wanted to do it, they would definitely have to think twice and make preparations before doing it seriously.
