Résumé
The impact of increasing recipient age on morbidity and mortality following living donor liver transplantation (LDLT) remains controversial. The study aims to analyze the impact of recipient age on outcomes following LDLT. Data on adult LDLTs performed between November 2009 and February 2020 were retrieved from a prospectively maintained database. Patients were stratified into 2 groups based on recipient age: 18 to 65 years (younger adults) and >65 years (older adults). Propensity score matching (PSM) using nearest-neighbor matching was used to match each older recipient with up to 2 younger adult recipients using multiple preoperative parameters. Outcomes evaluated were duration of ventilation, need for reintubation, tracheostomy, intensive care unit (ICU) readmission, length of ICU and hospital stays, postoperative complications, reoperation within 90 days, and patient survival. A total of 801 adult LDLT recipients were included in the study; 751 (93.7%) were younger adults, and 50 (6.3%) were older adults. Older recipients were more likely to be diabetic (60.0% versus 39.7%) and hypertensive (44.0% versus 20.4%) with preexisting cardiac disease (28.0% versus 11.2%). However, their pretransplant Model for End-Stage Liver Disease score was significantly lower (14.5 versus 17.7), and they were more likely to receive a transplant because of hepatocellular carcinoma (38.0% versus 17.7%). Older recipients had longer durations of ventilation after LT both before (3.7 versus 1.9 days) and after PSM (4.0 versus 1.5 days). After PSM, the 30-day (13.0% versus 2.4%), 90-day (15.2% and 2.4%), and overall mortality rates (21.7% versus 7.1%) were significantly higher for older recipients when compared with younger recipients. There was no difference between the younger and older recipients with respect to other postoperative outcomes. This propensity score-matched study shows that the older LDLT recipients have higher 30-day, 90-day, 1-year, and 5-year mortality rates when compared with matched younger counterparts.
