BACKGROUND/AIMS: The present study examined the impact of portoenterostomy on the morbidity and mortality of patients who later underwent living donor liver transplantation for biliary atresia. METHODOLOGY: Sixty-one consecutive patients from January 1996 to May 2001 were analyzed. They were divided into two groups according to the number of previous portoenterostomies: once (group A, n=26) and twice or more (group B, n=35). Preoperative status, mortality, morbidity, hospital duration and survival were examined and compared between the groups. RESULTS: Preoperative parameters regarding liver function and urgency status were comparable between the groups. The operation duration tended to be longer in group B than in group A (p=0.07). The blood loss and transfusion volumes in group B were greater than those in group A (p=0.03 for both comparisons). Vascular complications tended to be more frequent in group B patients. However, this difference was not significant (12% vs. 29%, p=0.06). The duration of hospitalization was longer in group B (p=0.04). Survival rates were comparable between the groups. CONCLUSIONS: Our surgical results suggest that multiple previous portoenterostomies might have negative short-term effects in patients who undergo living donor liver transplantation for biliary atresia.
