Abstract

Aim: We aimed to analyze the risk factors for early surgical complications requiring relaparotomy and the related impact on overall survival (OS) in HIV-infected patients submitted to liver transplantation. Methods: We performed a retrospective study on a nationwide multicenter cohort of 157 HIV-infected patients submitted to liver transplantation in 6 Italian transplant units between 2004 to 2014. Results: The median preoperative model for end-stage liver disease score was 18 (interquartile range 12-26.5). An early relaparotomy was performed in 24.8% of patients, and the underlying clinical causes were biliary leak (8.2%), bleeding (8.2%), intestinal perforation (4.5%), and suspected vascular complications (3.8%). The OS at 1, 3, and 5 years was 74.3%, 68.0%, and 60.0%, respectively, and an early relaparotomy was not a prognostic factor itself, but an increasing number of relaparotomies was associated with decreased survival (hazard ratio = 1.40, 95% confidence interval [CI] 1.07-1.81, P = .01). In the multivariate analysis, preoperative refractory ascites (odds ratio 3.32, 95% CI 1.18-6.47, P = .02) and Roux-en-Y choledochojejunostomy reconstruction (odds ratio 12.712, 95% CI 2.47-65.38, P ≤ .01) were identified as significant risk factors for early relaparotomy. Conclusions: In HIV-infected liver transplant recipients, an increasing number of early relaparotomies due to surgical complications did negatively affect the OS. Preoperative refractory ascites reflecting a severe portal hypertension and a difficult biliary tract reconstruction requiring a Roux-en-Y choledochojejunostomy were associated with an increased risk of early relaparotomy.
