Dealing with insufficient liver remnant: Associating liver partition and portal vein ligation for staged hepatectomy.

Liver resection for colorectal liver metastases has emerged to highly successful treatment in the last decades. Key to this success is complete hepatic tumor removal and systemic disease control by chemotherapy. Associating liver partition and portal vein ligation for staged hepatectomy is the most recent two-stage resection strategy for patients with very small future liver remnant making complete tumor removal possible within 1 to 2 weeks. Oncological outcome data are being collected at the moment and first results from small series reveal promising results.
