The professor studies cardiac surgery and vascular surgery. Frankfurt University Hospital; Studying endocrinology surgery with a professor. Rochel, etc. 200 1, he went to teach. John Fung is a senior visiting scholar in Pittsburgh who studies liver transplantation, living-related partial liver transplantation and small intestine transplantation. Professor studies pancreas transplantation, combined pancreas-kidney transplantation and islet transplantation. University of Minnesota at Sutherland. At present, he is the vice chairman of Liaoning Surgical Society of Chinese Medical Association, the consultant of Liaoning Vascular Surgery Society, the member of academic committee of China Medical University, and the editorial board of China Journal of Practical Surgery.

He is good at pancreatic surgery, liver surgery, biliary surgery, endocrine surgery, digestive tract surgery, vascular surgery and organ transplantation surgery. For many years, he is famous for his expertise in solving difficult and severe surgical operations. (1) Major in Pancreatic Surgery: Studying and researching in domestic pancreatic surgery centers. ① Extensive experience in radical operation of periampullary carcinoma. Pancreatoduodenectomy has been completed in nearly 1 000 cases, and the resection rate is over 99.6%. Up to now, he still holds the world record of the number of times and success rate of this kind of surgery by a single person, and he has completed more than 1 000 cases every year, which is constantly being refreshed. ② Pancreatoduodenectomy (PPPD) with pylorus preservation was carried out, with a large number of cases (more than 360 cases), ranking first in China. ③ The separation technology of bile and pancreatic juice was pioneered, which effectively prevented pancreatic leakage and greatly improved the recovery rate and safety after operation. ④ Start the bridge-type internal drainage of the main pancreatic duct to treat the leakage of pancreaticojejunostomy and preserve the residual pancreatic tissue. ⑤ The success rate of radical resection of pancreatic body and tail cancer is high (100%), and the postoperative effect is good. ⑥ Early decompression, focus clearance, drainage and other surgical treatments are advocated for acute severe pancreatitis, and postoperative support treatment is strengthened. The curative effect has reached the domestic advanced level. ⑦ Because of his outstanding achievements in pancreatic surgery, he won the third prize of scientific and technological progress in Liaoning Province in 2004. (2) Proficient in liver surgery: He skillfully combined liver surgery techniques (including Ken Takasaki Glisson's pedicled transverse hepatectomy) with vascular surgery techniques and liver transplantation techniques, which made the level and ability of liver surgery leap and the resection rate of liver tumors increased significantly. Many times in the so-called forbidden zone (I, VIII), huge liver tumor resection and difficult liver tumor resection were successfully performed, and about 60-70 cases of benign and malignant liver tumors were operated every year. Liver surgery technology is at the advanced level in China. (3) Good at biliary surgery: ① Rich experience in the treatment of hilar cholangiocarcinoma, including gallbladder carcinoma, hilar cholangiocarcinoma (Klatskin tumor), middle cholangiocarcinoma and lower common bile duct carcinoma.

The postoperative effect was good. ② Solve iatrogenic bile duct injury, and handle complicated bile duct operation problems for other hospitals and others for many times. ③ He is good at small incision cholecystectomy (more than 2,000 cases), which is both safe and beautiful.

(4) Good at vascular surgery: ① He has rich experience in the diagnosis and treatment of abdominal aortic aneurysm, arteriosclerosis obliterans, arterial embolism and venous vascular diseases for more than 25 years, and skillfully applies vascular surgery technology to surgery. ② The surgical treatment of portal hypertension is exquisite, and it is good at splenectomy and pericardial devascularization, which has formed the standardization of devascularization. ③ The shunt technique is improved, and various shunt operations can be completed. Limiting the diameter of splenic vein is the first choice to prevent encephalopathy and myelopathy after shunt, and the effect is good. ④ Small-caliber artificial blood vessel transplantation of spleen and kidney vein was performed at the same time in China. ⑤ advocate the combined surgical treatment of disconnection and shunt. 5] He is good at digestive tract surgery, and he is more skilled in related lymph node dissection on the basis of digestive tract tumor resection. [6] Good at endocrine surgery and breast surgery. I have studied and worked in endocrinology surgery in Germany for half a year, and endocrinology surgery is exquisite and unique. Once, many cases of liver transplantation were done. Master techniques of pancreas transplantation, kidney transplantation, small intestine transplantation and islet transplantation.
