Abstract
Roux-en-Y cholangiojejunostomy is a standard procedure for biliary reconstruction in pediatric living donor liver transplantation (LDLT). However, there is uncertainty on whether the adult standard of Roux branch limb is suitable for pediatric LDLT and its impact on postoperative biliary complications (BC). This study aimed to explore the effect of the short Roux limb and standard limb on pediatric LDLT biliary reconstruction. According to the length of the Roux limb, 168 LDLT children were divided into the routine limb group (n = 108) and the short limb group (n = 60). The incidences of postoperative biliary tract complications between the 2 groups were compared retrospectively. The mean Roux limb length in the short limb group was significantly shorter than that in the routine limb group group (P < .01). There were significant differences in age, height, and weight between the 2 groups (P < .01). However, there were no significant differences in graft-to-recipient weight ratio, intraoperative blood loss, cold ischemia time, and operation time between the 2 groups (P > .01). Moreover, postoperative BC, including refluxing cholangitis, were similar between the 2 groups (P = .876). Furthermore, the history of Kasai surgery, the history of postoperative RC of Kasai, and whether or not the Roux limb was reconstructed had no significant effect on the occurrence of postoperative RC. There was no significant difference in postoperative BC between the short limb and the routine limb in children with living donor liver transplantation.
