Bilioenteric Reconstruction Techniques in Pediatric Living Donor Liver Transplantation.

ABSTRACT

Biliary complications (BCs) are still a major cause of morbidity following liver transplantation despite the advancements in the surgical technique. Although Roux-en-Y (RY) hepaticojejunostomy has been the standard technique for years in pediatric patients, there is a limited number of reports on the feasibility of duct-to-duct (DD) anastomosis, and those reports have controversial outcomes. With the largest number of patients ever reported on the topic, this study aims to discuss the feasibility of the DD biliary reconstruction technique in pediatric living donor liver transplantation (LDLT). After the exclusion of the patients with biliary atresia, patients who received either deceased donor or right lobe grafts, and retransplantation patients, data from 154 pediatric LDLTs were retrospectively analyzed. Patients were grouped according to the applied biliary reconstruction technique, and the groups were compared using BCs as the outcome. The overall BC rate was 13% (n = 20), and the groups showed no significant difference (P = 0.6). Stricture was more frequent in the DD reconstruction group; however, this was not statistically significant (P = 0.6). The rate of bile leak was also similar in both groups (P = 0.6). The results show that the DD reconstruction technique can achieve similar outcomes when compared with RY anastomosis. Because DD reconstruction is a more physiological way of establishing bilioenteric integrity, it can safely be applied.
