Outcome of duct-to-duct vs. Roux-en-Y hepaticojejunostomy biliary anastomoses in below 15-kg pediatric liver transplant recipients.

ABSTRACT

The best type of biliary anastomosis to use in lower weight pediatric liver transplant recipients is debatable. In this study, we share a single center's experience comparing the rate of anastomotic biliary complications based on the type of biliary anastomosis performed in this population of patients. A retrospective review of pediatric liver transplants for recipients weighing <15 kg from 11/2003 till 12/2011 was performed. Patients were grouped based on the type of biliary anastomosis into two groups duct-to-duct (d-d) and Roux-en-Y hepaticojejunostomy (h-j) anastomoses. A total of 24 patients (12 males, 12 females) with a mean age of 26 ± 20 months and a mean weight of 9.27 ± 2.63 kg (range = 5.3-13.9 kg) were studied. All anastomotic complications occurred in patients who received left lateral segments. No statistical differences were found in the post-operative biliary (p = 0.86) or vascular (p = 0.99) complications between the two groups. Acknowledging the limited sample size, our data suggest that duct-to-duct anastomosis can be performed safely in pediatric liver transplantation recipients weighing below 15 kg.
