The optimal method of partial hepatectomy for pediatric transplants remains debated to this day: either <em>in situ</em> (<em>i.e.</em> occurring before liver removal from the donor) or <em>ex situ</em> (<em>i.e.</em> taking place after liver removal). In 2007, our tertiary academic center changed its surgical protocol from <em>ex situ</em> to <em>in situ</em> partial hepatectomy in deceased donor mainly to decrease bleeding complication risk among other amendments.

High short-term mortality for patients with ACLF admitted in ICU is a reason to ethically propose a liver transplantation as a curative treatment despite the existence of multi-organ failures. However, caution is advised for patients with grade-3 ACLF as they have to be attentively selected by a multidisciplinary approach, carefully evaluated and may benefit from an early transplant with a low-risk donor graft.
