Revision of porto-enterostomy in congenital biliary atresia.

For the patients with insufficient bile flow following porto-enterostomy for congenital biliary atresia, removal or resection of granulation or scar tissue at the porta hepatis has been performed. Of 11 reoperations, constant bile excretion was obtained in four. Sufficient resection of scar tissue at the porta hepatis was most important for revision of porto-enterostomy. For resection of scar tissue, a special scissors devised by us was used.
