Introduction: Liver transplantation (LT) is a complex and demanding procedure associated with significant perioperative challenges and risks. Concerns have arisen regarding LT outcomes in low-volume centers. We implemented an integrated training and surgical team network to address these concerns within the Catholic Medical Center (CMC) network. This study presents a comprehensive review of our 9-year LT experience within the CMC medical network.
Method: A retrospective study of LT procedures conducted between January 2013 and August 2021 in 6 CMC-affiliated hospitals was performed. One center was categorized as a high-volume center, conducting over 60 cases annually, and the remaining 5 were considered small-volume centers. The primary endpoints assessed were 1-year and 5-year survival rates.
Results: A total of 793 LTs were performed during the study period. The high-volume center performed 411 living donor LT (LDLT) cases and 127 deceased donor LT (DDLT) cases. Also, 146 LDLT cases and 109 DDLT cases were performed in 5 small-volume centers. One-year and 5-year patient survival for LDLT recipients was 88.3% and 78.8% in the high-volume center and 85.6% and 80.6% in the low-volume center. Five-year survival was not significantly different in small-volume centers (P = .903). For DDLT recipients, 1-year and 5-year patient survival was 80.3% and 70.6% in the high-volume center and 76.1% and 67.6% in the low-volume center. In DDLT cases, 5-year survival was not significantly different in small-volume centers (P = .445).
Conclusion: In conclusion, comparable outcomes for liver transplantation can be obtained in a small-volume center with a high level of integrated training systems and networks.
