Clinical outcome and neurological development of patients with biliary atresia associated with a bleeding tendency: a single institution experience.

PURPOSE: We compared the clinical features of patients with biliary atresia (BA) associated with a bleeding tendency (BT) at the time of the diagnosis with those of patients without a bleeding tendency (NBT). METHODS: The patients' background characteristics, age in days at the first visit, Kasai portoenterostomy (KPE), and postoperative course were retrospectively analyzed. RESULTS: Nine of the 93 BA patients (9.7%) showed a BT, including 7 with intracranial hemorrhaging (ICH), 1 with gastrointestinal bleeding, and 1 with a prothrombin time (PT) of 0%. The age at the first visit was 62 ± 12 days old for BT patients and 53 ± 27 days old for NBT patients (p = 0.4); the age at KPE was 77 ± 9 days old for BT patients and 65 ± 24 days old for NBT patients (p = 0.2); the time from the first visit to surgery was 13 ± 7 days for BT patients and 11 ± 10 days for NBT patients (p = 0.5); and the native liver survival rate was 56% for BT patients and 58% for NBT patients (p = 1), with no significant difference in any of the parameters. The neurological outcomes of survivors of ICH were favorable. CONCLUSIONS: Appropriate BT correction allowed early KPE even after ICH, resulting in native liver survival rates comparable to those of NBT patients without significant neurological complications.
