Core Tip
Core tip: Anatomical liver resection (AR) has been widely used for two decades in hepatocellular carcinoma and although many studies have shown the perioperative benefits, long term survival benefit of AR is still debated. For evaluation of benefits of AR, many factors should be considered, such as degree of cirrhosis, anatomical variation and surgical techniques. Moreover, critical review of previous studies considering bias is necessary. In this article, we review the results of several recently published, well-designed comparative studies of AR to investigate whether AR provides real benefits on survival outcomes. We also discuss the potential pitfalls associated with this approach.
