Description
Summary:Sarcopenia (SP) and preoperative muscle mass are independent predictive factors for short- and long-term outcome of liver transplantation. To assess the influence of muscle mass index (MMI) and preoperative SP on the prognosis of patients who underwent liver transplantation in our hospital. Ninety-seven patients who underwent liver transplantation in the Regional University Hospital of Málaga from September 2013 to March 2016 were analyzed. SP was determined based on the MMI, as assessed by psoas muscle area at the L4 level measured by computed tomography (CT), with adjustment for patient sex. Two cohorts were differentiated: 54 patients without SP and 42 patients with SP. Postoperative complications, graft survival, and patient survival were assessed. A 3-year follow-up was carried out. Recipient characteristics were similar in both cohorts, except for MMI ± SD (group without SP: 94.03 ± 15.43 cm2/m2 vs group with SP: 56.99 ± 13.59 cm2/m2; P = .001). The incidence of postoperative complications (Clavien ≥ 3) in patients with and without SP was 39.5% and 24.1%, respectively (P = .08). SP was not associated with poorer long-term graft or patient survival. SP, determined by preoperative measurement of MMI, was identified as a predictive factor associated with a higher incidence of postoperative complications. Since MMI can be easily determined by CT, it should be assessed in all candidates for liver transplantation.
