Risk Factors for Abdominal Bleeding After Living-Donor Liver Transplant

摘要

Objectives: The purpose of this study was to identify the incidence, outcomes, and risk factors of postoperative abdominal bleeding after living-donor liver transplant. Materials and Methods: Adult patients who had living-donor liver transplant between 2001 and 2013 were evaluated. Preoperative and intraoperative variables of transplant recipients were analyzed retrospectively with univariate analysis. Cox proportional hazards regression model was used to identify independent factors for postoperative bleeding. Results: There were 241 living-donor liver transplant recipients included in the study. Postoperative abdominal bleeding was observed in 12 recipients (5%). The 3-month cumulative survival was sig-nificantly lower in recipients who had postoperative bleeding (survival, 8 patients [67%]) than recipients who did not have postoperative bleeding (survival, 204 patients [89%]; P = .009). Univariate analysis showed that preoperative albumin level, Child-Pugh class, and intraoperative blood loss were risk factors for postoperative bleeding. In multivariate analysis, intraoperative blood loss and Child-Pugh status were significant risk factors for postoperative bleeding. Conclusions: Living-donor liver transplant recipients who had postoperative bleeding had a poor outcome. Postoperative bleeding was associated with higher intraoperative blood loss and Child-Pugh class.
