The standardized residency training has become a necessary way to improve the overall professional quality of doctors. At present, a single teaching model can't meet the needs of the standardized residency training. This study explores the application of problem-based learning (PBL) combined with multidisciplinary treatment (MDT) model in the general surgery teaching of standardized residency training, so that the residents can use their theoretical knowledge to think deeply about the problems in the cases. By consulting the literature review, the cases are analyzed from multiple levels and angles, such as pathogenic causes, pathogenesis and clinical manifestations, then the clinic diagnosis and therapeutic schedule can be obtained. This kind of teaching model not only stimulates the group's more interest in learning, and improves the ability of autonomous learning, independent analysis, problem solving and language expression, but also significantly improves teaching satisfaction and has obvious teaching advantages.
