Clinical Outcome and Future Liver Remnant Regenerative Response in Laparoscopic Versus Open ALPPS

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a surgical procedure that induces rapid liver regeneration in patients with small liver remnant planning for major liver resection. It is a two-staged operation with stage I including portal vein ligation and splitting the right liver away from the left liver. After stage I, the left liver will undergo rapid liver regeneration and the stage II operation can be performed at 7-10 days after stage I operation when the liver remnant reaches an adequate size. In stage II operation, the right liver that contains the tumor is then removed.
