Liver transplantation is a highly complex and challenging field of clinical practice. Although it was originally developed in western countries, it has been further advanced in Asian countries through the use of living donor liver transplantation. This method of transplantation is the only available option in many countries in the Asia-Pacific region due to the lack of deceased organ donation. As a result of this clinical situation, there is a growing need for guidelines that are specific to the Asia-Pacific region. These guidelines provide comprehensive recommendations for evidence-based management throughout the entire process of liver transplantation, covering both deceased and living donor liver transplantation. In addition, the development of these guidelines has been a collaborative effort between medical professionals from various countries in the region. This has allowed for the inclusion of diverse perspectives and experiences, leading to a more comprehensive and effective set of guidelines.

In a study on high-model end-stage liver disease (MELD) (score ≥ 30) LDLT recipients with ACLF (n = 190), defined by the World Congress of Gastroenterology [70], the 5-year survival rate was 72.1% [71]. In a study of 117 LDLT recipients who had ACLF, as defined by the EASL-CLIF definition, post-transplant survival after LDLT was 92.9%, 85.4%, and 75.6% at 1 year, while mortality rate without LT was 28.5%, 77.7%, and 93.4% at 90 days, for ACLF grades 1, 2, and 3, respectively [72]. These data indicate that LDLT can be a life-saving treatment option for patients with ACLF.LDLT differs significantly from DDLT, as the timing of LDLT can be determined by the transplant team. There are advantages and disadvantages of LDLT in the setting of ACLF. The benefit of LDLT in patients with ACLF is its ability to provide rapid transplantation to critically ill patients [73], without waiting for deceased donor allocation. The ideal time for LT can be selected by transplant team when willing living donor is available. If ideal time for LT can be selected in the dynamic course of ACLF, this may improve post-LT outcome. The disadvantages of LDLT include the need for healthy, willing liver donor, and the use of partial grafts for critically ill patients. A graft-to-recipient weight ratio (GRWR) is a factor associated with post-LT outcomes in LDLT [74]. The donor risk index is a factor associated with post-LT outcomes for patients with ACLF who received DDLT [66,75]. This indicates that DDLT, which uses whole liver grafts, might be a better compared to LDLT, which uses partial grafts, in ACLF. In addition, there are uncertainties regarding the criteria for living donor graft quality that is required for critically ill patients with ACLF. In studies that reported...
