[The pathomorphological changes of the retroperitoneum in acute pancreatitis].

Attention is focused on the development of a news idea. A comparative assessment of the body tissue tegmina--peritoneum and skin--is performed using a precise measuring unit--the square centimeter. Rating of pathological changes in the retroperitoneum in acute pancreatitis, similar to the one in thermal or chemical burns of skin, expressed in percents corresponding to the square centimeters of pathologically altered surface, is proposed.
