[Microcirculatory changes in patients with chronic diseases of the biliary tract]

Condition was studied of the microcirculatory bed in 80 patients with chronic noncalculous cholecystitis and 38 patients with calculous cholecystitis with the aid of biomicroscopy of bulbar conjunctiva and histological examination of removed gallbladders. Changes in microcirculation were characterized by enhancement of arteriole-venous shunting, diminution of the number of the functioning capillaries, appearance of signs of venous congestion, lowering of microvessel reactivity in an acute nitroglycerin test, which fact may suggest their systemic character.
