Abstract
Objective To investigate the correlation between the remnants of extrahepatic bilie duct with the prognosis of biliary atresia after Kasai operation. Methods From Sep.2005 to Sep.2011, 93 cases of biliary atresia [51 boys and 42 girls, ages at operation: 61 days(40-121 days)] in Tongji Hospital Affiliated of Tongji Medical College of Huazhong University of Science and Technology were operated with Kasai procedure, and the diagnosis of type Ⅲ biliary atresia was based on the cholangiography and the intraoperative findings.According to whether there was fibrotic remnant plates of porta hepatis or not, type Ⅲ biliary atresia cases were grouped into 2 subtypes: subtype A, in which there was fibrotic remnant plates of porta hepatis(n=80); subtype B, in which there was no fibrotic remnant plates, but solid cords structure like hepatic duct was observed(n=13). Specimens of the remnants were colleted in operation and pathologic section detected the degree of bile ductular proliferation in the remnants.Postoperatively, all of the patients were followed up.The contents included the cholangitis occurrence rate, the jaundice disappearance rate and survival rate during postoperative 2 years. Results The patients had more bile ductular proliferation in subtype A(χ2 =18.49, P 0.05). The jaundice disappearance rate in postoperative 6 months of subtype A was higher than the rate of subtype B(χ2 =9.19, P<0.05). The survival rate during postoperative 2 years of subtype A was higher than the rate of subtype B(χ2 =4.49, P<0.05). Conclusions There are higher jaundice disappearance rate and 2 years survival rate in type Ⅲ biliary atresia with the fibrotic remnant plates of porta hepatis, which suggest that there is more bile ductular proliferation in the extrahepatic remnants which is good for biliary drainage in subtype A after Kasai operation, and it can slow down hepatic injury and have a long-term good life quality. Key words: Biliary atresia; Kasai operation; Fibrotic plate; Prognosis
