The relationship between the number of well-developed bile canaliculi and patient prognosis was studied.Results The survival rate for 13 patients with well-developed intrahepatic biliary canaliculi and 12 patients with poorly-developed intrahepatic biliary canaliculi were 92.3% (12/13) and 33.3% (4/12) respectively. The difference between two groups was statistically significant (P<0.05).Conclusions Intrahepatic biliary canaliculi ultrastructure could be used as one of the prognostic factors in congenital biliary atresia.展开更多
