BACKGROUND: Donor safety is essential in living donor liver transplantation. In this study we assessed the association among perioperative factors, liver dysfunction, and complications in 251 consecutives right hepatectomies for living donation.
METHODS: Retrospectively collected data from a prospectively assembled cohort of 251 consecutive living donors who underwent right hepatectomy between 1999 and 2020 were evaluated.
RESULTS: Median age was 36 years; 54% were men. There was a statistically significant relationship between standardized liver volume by body surface area and the volumes calculated by imaging, weighting, and volume displacement. (r2 = 0.40, r2 = 0.34, and r2 = 0.34, respectively), with the relationship between standardized liver volume and liver volume by imaging being the strongest. The median remnant liver volume was 35%. Fifty-eight donors (23%) developed postoperative hepatic dysfunction, which was associated with increased length of stay (P = .04), and complications (P < .01). Men had a 2.5 times higher chance of developing postoperative hepatic dysfunction. Age >50 years was an independent predictor of increased bilirubin at postoperative day 4 (P < .01), and remnant liver volume was inversely associated with higher peak international normalized ratio (P < .01). Eighty-one donors (32%) experienced complications. Postoperative hepatic dysfunction was associated with 2.4 times higher chances of complications (odds ratio = 2.4, P < .01).
CONCLUSION: Early postoperative hepatic dysfunction is associated with the development of post-live liver donor complications. A thoughtful balancing of preoperative risk factors for postoperative hepatic dysfunction may indeed and by association reduce postoperative complications.
