  Xie Wanying thought that the leader was going to ask Dr. Song, and as a student, she had to work hard to answer the question, so she quickly and accurately found out the knowledge points in her mind:

   "The function of the liver lies in hepatocytes, and hepatocytes have a very rapid reproduction ability after partial hepatectomy. Half of the liver can be grown in three months. Therefore, the liver can be divided into eight parts as independent donors."

   Hmm, everyone listened to her and found that she became more and more fluent, a bit like a repeater.

"The division standard of the eight parts is the Couinaud segmentation method, which is marked clockwise according to the portal system, specifically the caudate lobe of segment I, the upper left lateral lobe of segment II, the lower left lateral lobe of segment III, and the left inner lobe of segment IV. , the lower right anterior lobe of segment V, the lower right posterior lobe of segment VI, the upper right posterior lobe of segment VII, and the upper right anterior segment of segment VIII. In addition to guiding surgery, it is also used to guide CT imaging diagnosis. In terms of practical operation, it is impossible to do To the eight segments used alone, surgeons often use segments I-IV of the left hepatic lobe, segments II-III of the left lateral lobe, and segments V-VIII of the right hepatic lobe."

   Xie Wanying answered in one breath, effortlessly.

   Obviously, her repeater is an excellent textbook example, with a clear voice and precise articulation, just like a teacher in a classroom.

  Teacher listened to her voice, her ears were like a spring breeze, and she enjoyed hearing it very much. So Deputy Director Xue continued to ask her: "Tell me again, this patient is a patient with liver cirrhosis who is undergoing liver transplantation, and there are patients with liver cancer in our department. Can they do liver transplantation?"

This question is more realistic, Xie Wanying thought quickly and answered the teacher: "First of all, it should be noted that most of our Asians have hepatocellular carcinoma referred to as HCC, and most of them have the background of hepatitis and liver cirrhosis. From this point of view, Rather than waiting for liver cancer before treatment, it is better to prevent and treat hepatitis first and slow down the development of cirrhosis, and it is better to do liver transplantation from the stage of cirrhosis when necessary.

   Yes, the answer immediately fits the question and cuts into the clinical focus. It is not just a scholar-like general talk that turns into a castle in the air. Listening to it makes the eyes of the old professor shine.

   She is right. The domestic doctors basically perform operations on domestic patients. Of course, domestic patients are patients with Asian characteristics. To be a clinical surgeon is to start from the actual situation and discuss the problems from the existing clinical cases around you. It seems that this female medical student has a very clinical sense of consciousness, not just talking about it on paper.

   Deputy Director Xue looked back at her, as if to remember her appearance in his mind. After all, medical students like her are rare.

   "Tell me again, under what circumstances can liver transplantation be done for liver cancer?"

Xie Wanying replied: "Small liver cancer can be done, that is, liver cancer with a tumor diameter of less than five centimeters. The five-year survival rate of such patients after liver transplantation can reach 70 to 80 percent. Compared with traditional resection, it has certain advantages. Because HCC Less than 20 percent of the patients who underwent liver tumor resection were cured.”

   "What about other patients?"

"For patients with advanced liver cancer and portal vein tumor thrombus, the recurrence rate after transplantation is too high, and most of them live less than a year. Domestic liver sources are scarce, so it is best to implement liver transplantation adaptation to liver cancer according to the Milan standard proposed internationally. disease."
