[Biliary regeneration. Experimental studies in rats (author's transl)]

Cholangiographic and histological examinations after partial hepatectomy in rats have demonstrated the presence of biliary as well as hepatocyte regeneration. Commencing very soon after hepatectomy, biliary degeneration is confirmed by radiological investigation, showing hypertrophy of the intra-hepatic biliary canals, and corroborated histologically by evidence of mitoses in the biliary epithelium. This suggests that intravenous cholangiography can be a simple means of evaluating hepatic regeneration after partial hepatectomy in humans.
