Abstract
R0 resection of colorectal liver metastases is the main curative treatment option; however, 85% of patients are considered initially unresectable, either due to number, size and location of metastases or insufficient future liver remnant. ALPPS is a complex surgical technique, which allows, in two operative times, the resection of extensive portions of liver parenchyma after a period of volumetric remnant increase, which reaches 80% in 9 days, far exceeding other techniques as well as preoperative portal embolization / ligation. Despite initial doubts regarding the associated morbidity and mortality, the significant gain in hepatocellular mass achieved with ALPPS has allowed the successful treatment of patients with high hepatic metastatic tumor burden, questioning fundamental principles classically considered for safely performing major hepatectomies. The aim of this article is to show the initial experience with the ALPPS technique application taken to the extreme of leaving a liver remnant made up of a single segment.
