| Abstract: | The epidemiology of infection after liver transplantation for hilar cholangiocarcinoma has not been systematically investigated. In this study of 124 patients, 255 infections occurred in 105 patients during the median follow‐up of 4.2 years. The median time to first infection was 15.1 weeks (IQR 1.6‐62.6). The most common sites were the abdomen, bloodstream, and musculoskeletal system. Risk factors for any post‐transplant infection were pre‐transplant VRE colonization (Hazard Ratio HR] 1.9, P=.002), living donor transplantation (HR 6.6, P<.001), longer cold ischemia time (HR 1.05 per 10 minutes, P<.001), donor CMV seropositivity (HR 2.2, P<.001), hepatic artery thrombosis (HR 2.6, P=.005), biliary stricture (HR 3.8, P=.002), intra‐abdominal fluid collection (HR 4.2, P<.001), and re‐operations within 1 month after transplantation (HR 1.7, P=.020). Abdominal infections were independently associated with hemodialysis requirement within 1 month after transplantation (HR 5.6, P=.006), hepatic artery thrombosis (HR 3.3, P=.007), biliary stricture (HR 5.2, P<.001), and abdominal fluid collection (HR 3.7, P=.0002). Bloodstream infections were independently associated with allograft ischemia (HR 17.8, P<.001), biliary stricture (HR 6.5, P=.005), and recipient VRE colonization (HR 4, P<.001). Abdominal infections (HR 2.3, P=.02) and Clostridium difficile infections (HR 4.6, P=.01) were independently associated with increased mortality. |
