Morphological speculation of the MHPD and related clinical projections.

Objective: The concept of mesopancreas has been brought into focus nowadays. Studies on membrane morphology of pancreas are clinically significant in determining an ideal surgical route for a "holy plane". In this paper, we aimed to observe the structure of the peripancreatic membranes and its interactions with adjacent tissues; tentatively put forward the proposition of mesohepatopancreaticoduodenum (MHPD) and explore in depth in surgical local resection.
