Impact of Total Parenteral Nutrition on Preoperative Management of Pediatric Living-Donor Liver Transplantation for Biliary Atresia Under 2 Years Old.

Background: Liver failure and gastrointestinal bleeding occur in the end-stage of biliary atresia (BA). Living-donor liver transplantation (LDLT) is a standard treatment in Japan. Our program actively provides pre-transplant total parenteral nutrition (TPN) for such patients, and here we report its efficiency and safety.

Methods: Patients with BA for whom LDLT was indicated were identified. Those with a long-term external central venous catheter and TPN, longer than 4 weeks before LDLT, were analyzed. Ascites was controlled with diuretics. TPN indications, efficacy, and complications were assessed along with patient growth, biochemical markers, and gastrointestinal bleeding.

Results: Fourteen patients were included in the study, of whom 8 were girls and 6 were boys. The median age at LDLT was 0.9 years. Body weight (BW) at TPN initiation averaged 6799 g, and the median serum total bilirubin was 9.5 mg per dL. The median catheterization duration was 54 days, and 1 patient received home TPN. Indications for TPN were gastrointestinal bleeding and/or massive esophageal varices in 4 patients and poor nutritional status in 10 patients. No complications were observed except for 1 catheter infection and 1 catheter occlusion. The median final body weight before LDLT was 7906 g. The mean rate of BW gain was significantly higher after TPN than before (149 vs 32 g/wk, respectively, P = .0002). Mean prothrombin time and levels of albumin, cholinesterase, and total bilirubin were not significantly different at the start and end of TPN.

Conclusions: Pre-transplant TPN was safe and effective for patients with end-stage BA.
