Liver malignancies are the fifth most common cause of death worldwide. Surgical intervention with curative intent is the treatment of choice for liver tumors as it provides long-term survival. However, only 20% of patients with metastatic liver lesions can be managed by curative liver resection. In most of the cases, hepatectomy is not feasible because of insufficient future liver remnant (FLR). Two-stage hepatectomy is advocated to achieve liver resection in a patient who is considered to not be a candidate for resection. Procedures of staged hepatectomy include conventional two-stage hepatectomy, portal vein embolization, and associating liver partition and portal vein ligation for a staged hepatectomy. Technical success is high for each of these procedures but variable between them. All the procedures have been reported as being effective in achieving a satisfactory FLR and completing the second-stage resection. Moreover, the overall survival and disease-free survival rates have improved significantly for patients who were otherwise considered nonresectable; yet, an increase in the morbidity and mortality rates has been observed. We suggest that this type of procedure should be carried out in high-flow centers and through a multidisciplinary approach. An experienced surgeon is key to the success of those interventions.
Core tip: Surgical intervention with curative intent is the treatment of choice for liver tumors. A variety of techniques have been established to increase the possibility for resectability. Two-staged hepatectomy, with its distinguishing beneficial procedures, is one of the techniques that have been proposed to overcome this clinical challenge. In spite of higher perioperative morbidity and mortality associated with this procedure, the overall survival and disease-free survival rates have increased significantly. Patient selection through consensus by a multidisciplinary board panel is the mainstay to successful performance of this procedure.
