Abstract
BACKGROUND: Preoperative anemia was reportedly associated with increased morbidity and mortality after various types of surgeries. However, its impact on the outcomes after liver transplantation has not been thoroughly investigated. METHODS: We retrospectively investigated the clinical outcome of 216 consecutive adult patients who underwent living donor liver transplantation at our institute between January 2010 and June 2017 and stratified them according to the hemoglobin level before transplant. Risk factors for 90-day patient mortality, especially infection-related mortality and early graft loss, were evaluated. RESULTS: We found that patients with preoperative hemoglobin below 10 g/dl required more intraoperative packed red blood cell transfusions (p = 0.002) and had significantly higher early 90-day postoperative mortality rate (p = 0.007), particularly infection-related mortality (p = 0.002), lower overall graft, and patient survival rates (p = 0.007, p = 0.013, respectively). Preoperative hemoglobin below 10 g/dl was an independent risk factor for increased post-transplant 90-day patient mortality (OR 2.92, p = 0.02), infection-related mortality (OR 6.81, p = 0.02), and early graft loss (OR 3.26, p = 0.01). CONCLUSION: Preoperative hemoglobin level below 10 g/dl is associated with poorer short-term outcomes after liver transplantation and should be corrected preoperatively if possible through safe and effective treatment modalities.
