A worldwide survey of Live liver donor selection policies at 24 centers with a combined experience of 19 009 adult living donor liver transplants

Background While surgical technique in LDLT has evolved with a focus on donor safety and recipient challenges, the donor selection criteria remain considerably disparate. Methods A questionnaire on donor selection was sent to 41 centers worldwide. 24 centers with a combined experience of 19009 LDLTs responded. Results Centers were categorized into predominantly LDLT (18) or DDLT (6), and high (10) or low volume (14) centers. At the majority of centers, the minimum acceptable GRWR was 1 features of metabolic syndrome. On biopsy, all considered macrovesicular and 50% considered microvesicular steatosis important. Nearly all (92%) rejected donors for early fibrosis, and minority for nonspecific granuloma or mild inflammation. Most anatomical anomalies except portal vein type D/E were acceptable at high volume centers. There was no standard policy for pre or peroperative cholangiogram. Conclusions This first large live liver donor survey provides insight into donor selection practices that may aid standardization between centers, with potential expansion of the donor pool without compromising safety.
