Professor Yu is an academic leader in the Department of Gastroenterology. Below is his personal information, but it is difficult to hang up his clinic. Judging from the patient's situation described above, you don't need to hang up his number directly. You can go to the Friendship Hospital first and sign the expert number (any one) for further diagnosis.

Professor Yu has been engaged in gastroenterology for more than 40 years. He has a profound understanding of endoscopic diagnosis and treatment of digestive system diseases and rich clinical experience. He is good at treating esophageal varices, gastrointestinal polyps and early cancer. In the treatment of primary liver cancer, good cases with survival time of 10 year, 8 years and 5 years were obtained, and the pain of a large number of patients was relieved. He was closely linked with the clinic, actively innovated and developed, and took the lead in carrying out biliary drainage in the study of digestive endoscopy, which reduced the mortality rate of severe complications of obstructive jaundice from 1 1.3% to zero, and took the lead in carrying out percutaneous cholangiography and internal and external drainage in China. Interventional therapy for liver cancer is the earliest, and the one-year survival rate has reached 60%. The longest survivor has lived 1 1 year. For the first time, the sclerotherapy of liver cyst guided by B-ultrasound was carried out, which made the cyst closure rate reach 80%, and the recurrence after surgical window opening also achieved the closure effect. The mortality rate of esophageal variceal bleeding is extremely high, and the direct injection method under endoscope has many complications, which is difficult to popularize. First, use ST-

E 1 tube treated with thrombin sclerosing agent, and later ligation method, made the treatment extremely safe and accurate, and quickly popularized in China; An esophageal variceal ligation device suitable for domestic use has been designed, which has been adopted by hundreds of hospitals in China, providing a means for the prevention and treatment of esophageal variceal bleeding due to liver cirrhosis and obtaining a national patent. The application of integrated traditional Chinese and western medicine proves that Brucea javanica oil emulsion is a good protective agent for gastric mucosa, which can not only reduce the thickness of inflammatory infiltration of gastric mucosa, but also increase endogenous prostaglandin and reduce the damage of oxygen free radicals to gastric mucosa. Compared with Mei Wei, Thailand, it is a rare protective agent for gastric mucosa. In order to actively promote and popularize endoscopic diagnosis and treatment technology and improve domestic academic level, Professor Yu organized a large-scale national academic exchange meeting, exchanged endoscopic diagnosis and treatment technology in grass-roots hospitals, and founded the Beijing Digestive Endoscopy Reading Club. In order to promote international communication and improve the international status of digestive endoscopy in China, Professor Yu presided over an international academic and operational demonstration conference on digestive endoscopy every two years, and invited world-renowned digestive endoscopy experts to give reports and demonstrations, which improved and developed the level of digestive endoscopy in China.
