Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for pediatric mesenchymal hamartoma: A case report.

The case involves a one-year-old male with a mesenchymal hamartoma involving the right hepatic lobe. The tumor-free segments comprised 17% of the liver volume, which placed the patient at risk for post-resection liver failure. A staged approach, the associating liver partition with portal vein ligation for staged hepatectomy, was employed.
