Risk factors and prevention of biliary anastomotic complications in adult living donor liver transplantation

AIM: To evaluate risk factors of biliary anastomotic complications (BACs) and outcomes according to type of biliary reconstruction. METHODS: A total of 33 consecutive adult living donor liver transplantation (LDLT) were reviewed, 17 of which had undergone Duct-to-Duct anastomosis (D-D). The remaining 16 patients received Roux-en-Y anastomosis (R-Y). The perioperative factors, such as the type of graft and the number of graft bile ducts, were analyzed retrospectively. RESULTS: The overall incidence of BACs was 39.4%. The incidence of BACs was significantly higher in the patients with than without neoadjuvant chemotherapy (71.4% vs 10%, P = 0.050). There was no signifi cant difference in the incidence of biliary leakage in patients with D-D vs those with R-Y. The incidence of biliary strictures following the healing of biliary leakage was significantly higher in D-D (60%) than in R-Y (0%) (P = 0.026). However, the incidence of BACs related bacteremia was signifi cantly higher in R-Y than in D-D (71.4% vs 0%, P = 0.008). In D-D, use of T-tube stent remarkably reduced the incidence of BACs, compared with straight tube stent (0% vs 50%, P = 0.049). CONCLUSION: Our experience showed an increase of BACs related bacteremia in the patients with R-Y. Therefore, D-D might be a preferred biliary reconstruction. However, the surgical refi nement of D-D should be required because of the high incidence of biliary strictures. Use of the T-tube stent might lead to a signifi cant reduction of BACs in D-D.
