[Surgical classification of liver local lesions]

There is a variety of liver focal lesions (LFL) and every clinical case should be considered carefully in deciding the problem of indications to surgical treatment. The existing classifications, including the TNM classification, are limited by the peculiar features of liver anatomy. The authors propose an original surgical classification of LFL that combines TNM principles and segmental characteristics of volume of lesion. The classification takes into account intraorganic and extraorganic location of LFL, and marks it by special letter indices. The indication of nosology of LFL in combination with letter and a B digital indices provides the universality of classification. The authors recommend to use the classification in evaluation of malignant and benign liver lesions, as well as alveococcosis and liver trauma.
