ALPPS
Pronunciation: AL-ps
Also written as: ALPPS — Associating Liver Partition and Portal vein ligation for Staged hepatectomy
Two-stage surgical procedure for extensive liver resection involving portal vein ligation followed by hepatectomy.
Full Definition
Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) is a novel two-stage surgical technique developed to enable curative resection in patients with extensive liver tumors. The first stage involves transection of the liver parenchyma along the intended resection line and ligation of the portal vein branches to the diseased segments. This induces rapid hypertrophy of the future liver remnant. The second stage, performed 1-2 weeks later, completes the hepatectomy by removing the prepared segments.
Usage
Usage note: Always capitalize as acronym; refer to individual stages as 'ALPPS stage I' and 'ALPPS stage II'.
