Outcomes of living-donor liver transplantation for acute-on-chronic liver failure based on newly proposed criteria in Japan.

Proper use of the new diagnostic criteria for ACLF in Japan demonstrated that the presence and severity of ACLF, especially the presence of multiple organ failures, leads to morbidity and mortality even in an LDLT setting. Considering that the patients with ACLF Grade 3 do not have the favorable outcomes of LDLT, deceased-donor liver transplantation usage, or LDLT before reaching the severity of Grade 3 may be suitable for further research.
