Effect and Mechanism of ALPPS Operation on Liver Regeneration

In recent years, Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) provides new hope for the solution of large/unresectable hepatobiliary malignancies. This technique promotes the rapid proliferation and regeneration of the remaining liver by separating the liver and ligation of the portal vein, so that the patients whose original liver function is not enough to tolerate large-scale liver resection can complete liver regeneration in a short time, so as to perform secondary resection. Compared with traditional two-stage hepatectomy, ALPPS significantly speeds up the rate of liver regeneration, shortens the waiting time for a second surgery, and provides a safer radical treatment for tumors in high-risk patients.
