[Are various theoretical models of membrane anatomy mutually exclusive or inclusive?].

The theory of membrane anatomy is now widely accepted due to the observation of fine anatomical structure with the help of laparoscopic magnifying effect. From the perspective of systematic anatomy, the mesentery is considered as an integral organ in the theory of mesenteric anatomy. Interfascial anatomy belongs to regional anatomy, which focuses on the guiding significance of fascial space for operation. The theory of membrane anatomy belongs to surgical anatomy or applied anatomy, which emphasizes the anatomy of membrane and mesangial bed, and reveals the existence of 'metastasis V' in the mesentery. It is considered that the essence of membrane anatomy operation is to prevent cancer leakage. Various theories of membrane anatomy seek common ground while reserving differences, complement each other, and upgrade iteratively. They help to explain the structure and function of membrane from different perspectives and they are of great benefit to improve the quality of operations. Thus, they should be treated in an eclectic manner.
