Abstract

This study aimed to evaluate the association of postoperative thrombocytopenia with outcome following adult living donor liver transplantation (LDLT) for end-stage liver disease (ESLD). It was a prospective study of 120 consecutive adult LDLT from September 2012 to May 2015. Preoperative platelet counts (PLTs) and postoperative PLTs were recorded at regular intervals till 3 months after LDLT. Univariate and multivariate analyses were performed. The median pretransplant PLT was 61 × 10(9) /l. The lowest median PLT after LDLT was observed on POD 3. Patients were stratified into low platelet group (n = 83) with PLT <30 × 10(9) /l and high platelet group (n = 37) with PLT ≥30 × 10(9) /l. Patients with PLT <30 × 10(9) /l had statistically significant higher grade III/IV complication (P = 0.001), early graft dysfunction (P = 0.01), sepsis (P = 0.001), and prolonged ascites drainage (P = 0.002). On multivariate analysis, PLT<30 × 10(9) /l was identified as an independent risk factor for grade III/IV complications (P = 0.005). Overall, patients survival was significantly different between two groups (P = 0.04), but this predictive value was lost in patients who survived more than 90 days (P = 0.37). Postoperative PLT of <30 × 10(9) /l was a strong predictor of major postoperative complications and is associated with early graft dysfunction, prolonged ascites drainage, and sepsis. The perioperative mortality rate was high in the thrombocytopenia group.
