I have long been engaged in clinical work in the field of minimally invasive biliary surgery, with particular long-term accumulation of experience in the rational selection of minimally invasive treatment for extrahepatic bile duct stones and the treatment of various benign and malignant biliary strictures. In recent years, I have been committed to the development of single-incision laparoscopic cholecystectomy, laparoscopic cholecystectomy combined with choledochotomy and stone extraction, and same-session general anesthesia endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy and stone extraction combined with laparoscopic cholecystectomy, as well as painless ERCP. I have completed 1 project funded by the Municipal Science and Technology Commission and 2 projects funded by the Municipal Health Bureau. As first author or corresponding author, I have published more than 50 professional papers in domestic core journals and more than 10 SCI papers. I participated in the writing of ten professional books, including Shi Weijin's Biliary Surgery.
