The Regenerative Capacity of the Donor Liver After Living Donor Liver Transplantation: an Ambidirectional Cohort Study

Sponsor: Erasmus Medical Center

Summary

Rationale: Living donor liver transplantation (LDLT) offers a promising solution to the organ shortage. During living liver donation, a substantial portion of the donor's liver is resected. Fortunately, the liver has a remarkable capacity to regenerate. However, liver regeneration varies among individuals. Previous studies have identified several clinical factors as potential predictors of regenerative capacity. Nevertheless, these studies are outdated and do not reflect current clinical practice or recent advancements. This study aims to investigate the regenerative capacity of the donor liver following LDLT and identify its clinical predictors. It is hypothesized that the liver regenerates to the original size. Objectives: The main objective of this study is to evaluate the regenerative capacity of the donor liver following LDLT. The secondary objective is to identify clinical predictors of the regenerative capacity of the donor liver following LDLT. Study type: This is an ambidirectional, single-center cohort study using medical records. Study population: The population consists of adult living liver donors aged 18-60 years at the Erasmus MC who donate(d) between May 2004 and June 2026 and gave written informed consent. Methods: General, graft weight and liver volumetry data will be extracted from HiX. The study coordinator will register his findings and analyze them. The paired samples t-test will be used to test for differences in mean remnant liver volume and liver volume 12 months post-donation. In addition, subgroup analyses will be performed for sex, age, weight, type of liver graft donation, anatomical variants, liver steatosis, and donor complications. Multiple linear regression analysis will be performed for sex, age, BMI, donor length of stay, remnant liver volume and percentage, and type of liver graft donation.
