Surgical treatment of liver pathology can be successful only if sufficient knowledge of the anatomical and topographic features of the organ, its blood supply and bile flow. The liver begins to differentiate at the 3rd week of embryonic development from the protrusion (diverticulum) of the primary intestinal tube. Peritoneum and liver ligaments. The diverticulum spreads to the right hypochondrium between the two layers of the mesoderm, and therefore the liver is almost completely covered by the peritoneum, coming from neighboring organs and forming connections with them in the form of ligaments.
