Visualization of routes of lymphatic drainage of the gallbladder with a carbon particle suspension.

Abstract

These data demonstrate that the right route is a main pathway of lymphatic drainage from the gallbladder, while the left and hilar routes are branch lines. The para-aortic nodes, regarded as final regional nodes for the gallbladder, should be removed during radical surgery for advanced carcinoma of the gallbladder. Drainage along the hilar route may cause metastasis to the liver.
