With over 30 years of clinical experience in general surgery, I specialize in the comprehensive surgical treatment of various general surgical diseases, particularly gastrointestinal tumors, and have accumulated experience from thousands of gastric and colorectal cancer surgeries. I also have extensive clinical experience in the diagnosis and treatment of various complex diseases in general surgery. Additionally, I have been dedicated to basic and clinical research on gastrointestinal tumors for more than 20 years, and have authored applications for and participated in multiple research projects, including the Shanghai Municipal Science and Technology Commission's Clinical Medicine Key Discipline Project. I have published numerous related papers in core journals and have assisted in the supervision and training of 5 master's students.
