Abstract    Objective    To investigate the surgical anatomical and histological data for the mesopancreas and mesopancreatic excision. Methods    The anatomic structures of the peripancreatic space，the important vessels and the retroperitoneal structures of 5 cadaveric specimens between January and December 2016 in Basic Medicine Faculty of Shanghai Jiao Tong University were observed in the study. The structures of the vessels and retroperitoneum were histological studied. Results    Posterior pancreatic space was an important anatomical plane of mesopancreatic excision. Celiac trunk and superior mesenteric artery were important anatomic landmarks of mesopancreatic excision. The No.16 lymph node was the extra anatomy structure of mesopancreas. There was a natural surgical space between the adventitia and sheath of the artery. There was a great deal of nerve and lymphatic vessel distribution on and outside the arterial sheath of the peripancreatic arteries.  Conclusion    Mesopancreas and mesopancreatic excision have the corresponding basis of surgical anatomy. Arterial sheaths dissection strategy for improving the dissection effect has certain anatomical basis.
