Abstract
BACKGROUND/PURPOSE
Lung transplantation in Taiwan began in 1991, but the experience was limited and diverse in the early years. We examined the cumulative institutional experience of the largest lung transplant cohort in Taiwan.
METHODS
A retrospective review of lung transplantations performed at a single institution from December 1995 through August 2016 was conducted. For comparative purposes, the cohort was divided into halves, with an early group (undergoing lung transplantation in the first decade) vs a late group (undergoing lung transplantation in the second decade). Standardized donor selection, organ procurement, and preservation protocols for brain-dead donors were applied. The outcomes measured were 30-day mortality and actuarial survival using the Kaplan-Meier method.
RESULTS
The cohort included 50 recipients in the early group and 42 recipients in the late group. Compared with the early group, recipients in the late group were significantly older (38.8 ± 11.6 vs 44.8 ± 13.4 years, p = 0.024) and more of them required mechanical ventilation before transplant (26.0% vs 66.7%, p < 0.001). There were more female donors (12.0% vs 33.3%, p = 0.021) and gender-matched donors (34.0% vs 61.9%, p = 0.012) in the late group. A total of 87 recipients (94.6%) had cardiopulmonary bypass (CPB) or extracorporeal membrane oxygenation (ECMO) support during transplant, and CPB was used significantly less in the late group. Graft procedures (14.0% vs 47.6%, p < 0.001), delayed chest closure (0% vs 21.4%, p < 0.001), and early tracheostomy (24.0% vs 52.4%, p = 0.005) were performed more in the late group. The durations of hospital and ICU stays were comparable in both groups, but the 30-day mortality was significantly lower in the late group (30.0% vs 2.4%, p = 0.001).
CONCLUSION
Although the results were undesirable in the first decade of the transplant program, the cumulative institutional experience led to significantly improved outcomes in the second decade of the transplant program.
