Endocrine changes following partial hepatectomy

Subtotal hepatectomy and all the paraoperative actions induce a condition of stress characterized by the intensification of catabolic processes and overproduction of hormones with glycogenolytic and lypolytic action: catecholamines, T3, T4, ensuring the conditions required by some energy-dependent processes (mitoses and proteosyntheses) assuring the regeneration of the operated liver. The latter presents a depletion of dehydrogenases, of PAS + materials and fatty loading of the liver cells. In the conditions of liver distress, the muscles are those which supply the glucose, ensuring an as rapid as possible return of glycemia to normal values.
