Résumé
With the development of fine anatomy,the concept of mesopancreas has been proposed,and total mesopancreatic excision continues to be used in clinical practice.This method has become the best surgical method of pancreatic head cancer.But due to deep position of pancreas and mesopancreas,the surrounding adjacent organs and complexs tructure and other factors,experts are concerned about at the presence or absence of the mesopancreas.So the scope of clinical surgical resection structural reservations are also controversial.This article reviewed the development of embryonic development of the pancreas and the research progress in order to provide theoretical support for the study of the fine anatomy of the pancreas and the precise operation of pancreatic diseases.
