Abstract
During the past 8 yr, 37 patients with a noncorrectable type of biliary atresia have undergone hepatic portoenterostomy or portocholecystostomy at the Kobe Children's Hospital. The hepatic portal dissections employed in this series were classified as "supraportal" (9 procedures), "portal" (25 procedures), and "infra-portal" (3 procedures) based on the level at which the fibrous mass at the porta hepatis was transsected as determined by the operative record and the pathologic findings. Successful biliary drainage was achieved in 19 out of 25 patients (76%) with a "portal" type of dissection, while 1 out of 9 with "supra-portal" and none out of 3 with "infra-portal" type dissections were successful in this respect. Of the 19 patients who achieved significant biliary flow, 8 have lived for 2--7 yr without jaundice and 3 others are jaundice-free for shorter intervals.
