I have long been engaged in clinical work in the field of minimally invasive biliary surgery, with particular long-term accumulation in the rational selection of minimally invasive treatment for extrahepatic biliary 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, simultaneous endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic papillary balloon dilation or sphincterotomy under general anesthesia combined with laparoscopic cholecystectomy, and 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 have participated in the compilation of more than ten professional books, including "Shi Weijin Biliary Surgery."
