[Anatomopathologic repercussions of segmental liver resection].
We present an experimental study of the anatomopathologic repercussions of segmental liver resection. Sixty rats were used, distributed into 3 groups of 18 animals each one with 6, group I, as follows: 1) anesthesia and laparotomy; 2) 30% liver resection; 3) 50% liver resection, and 4) 80% liver resection. The three resection groups were distributed into three subgroups according to parameters studied at 24 hours, 72 hours and 10 days, respectively. The data studied were: 1. Inflammation: activation of Kupffer cells, state of the lobule and portal spaces. 2. Degeneration: steatosis, necrotic foci, infarction and eosinophilic degeneration. 3. Regeneration: hepatocytic hypertrophy, mitosis, binucleation and trabeculation. The results confirm that the resected liver undergoes regenerative processes that condition the adaptation of the animal after hepatic exeresis.
