Abstract
Infected hepatic fluid collections (bilomas) are a major infectious complication of liver transplantation. Limited data exist on management and outcome of biloma. We report a cohort study of 57 liver transplant recipients with posttransplantation bilomas undertaken to identify the clinical features of biloma, management strategies, and outcome. Fever (44%) and abdominal pain (40%) were the most common presenting symptoms, but one-third of patients were asymptomatic; 79% had elevated hepatic enzyme levels. Patients without hepatic artery thrombosis (HAT) had the highest rates of resolution with percutaneous drainage and anti-infective therapy (64%). Retransplantation was necessary in 64% of patients with HAT and biloma. Independent predictors of resolution with nonsurgical therapy were absence of HAT (odds ratio [OR] 7.69; P=.01) and absence of Candida (OR, 9.09; P=.02) or enterococcal infection (OR, 7.69; P=.03). Patients with bilomas had significantly greater mortality (Cox proportional hazard ratio [HR], 2.38; P=.008, by log rank test) and graft loss (HR, 4.31; P<.0001). Predictors of mortality by multivariable analysis included renal insufficiency (OR, 12.51; P=.02) or infection with Candida species (OR, 4.93; P=.03) or gram...Continue Reading
