Observations on hepatic superficial lymph flow.

Hepatic superficial lymph flow was studied by injecting patent blue V solution into the liver under peritoneoscopy. This procedure enabled detailed observations of the direction of hepatic lymph flow in superificial lymphatic vessels and migration of lymph from these lymphatic vessels to lymphatic vessels of the gallbladder. Increase in this flow was observed in patients with increased liver fibrosis and lobular distortion.
