RESUMEN
BACKGROUND: The so-called grafts or donors with extended criteria are a risk factor for the development of liver transplant activity. One source comes from controlled donation after circulatory death (cDCD). The hypothesis was to verify the improvement in results by comparing DCD liver transplants performed with postmortem normothermic regional perfusion (NRP) vs super-rapid recovery (SRR), the current standard for cDCD. A prospective study comparing both techniques was carried out. METHODS: A total of 42 transplants were performed with cDCD, 22 of which were with SRR and 23 with NRP from April 2014 to September 2019. RESULTS: Differences were found in early allograft dysfunction (68.1% in the SRR group vs 25% in the NRP group; P < .01) and biliary complications (22.7% vs 5%, respectively; P = .04). Differences were also found, although not statistically significant, in ischemic cholangiopathy (13.6% in the SRR group vs 5% in the NRP group; P = .09), and retransplant rate (9.1% vs 0%, respectively; P = .3). CONCLUSIONS: With the use of NRP machines, results are similar to the standard donation with donors in brain death in terms of rate of early allograft dysfunction and survival of the patient and graft attempted, reducing the rate of ischemic cholangiopathy compared with SRR.

BACKGROUND: Sarcopenia (SP) and preoperative muscle mass are independent predictive factors for short- and long-term outcome of liver transplantation. OBJECTIVE: To assess the influence of muscle mass index (MMI) and preoperative SP on the prognosis of patients who underwent liver transplantation in our hospital. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
