Abstract
Hepatectomy is widely regarded as the primary treatment for hepatic malignancies; yet, postoperative liver failure remains a major cause of perioperative mortality, severely impacting patient outcomes. In a robust hepatic environment, the future liver remnant (FLR) must exceed 25%, and in cases of cirrhosis, this requirement increases to over 40%. The inadequacy of FLR is currently a major obstacle in the progression of hepatic surgery. Traditional methods to enhance FLR hypertrophy mainly focus on portal vein embolization (PVE), but its effectiveness is considerably limited. In recent years, there have been numerous reports on a novel biphasic hepatectomy method involving hepatic partitioning and portal vein ligation, known as associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). ALPPS surpasses PVE in efficiently and considerably inducing FLR hypertrophy. However, the detailed mechanisms driving ALPPS-facilitated hepatic regeneration are not fully understood. Thus, replicating ALPPS in animal models is crucial to thoroughly investigate the molecular mechanisms of hepatic regeneration, offering valuable theoretical and practical insights.
