Abstract: The deficiency of future liver remnant (FLR) is one of the important reasons that restrict radical surgery in some patients with liver cancer. Two-step hepatectomy is a gradually developed surgical method in the treatment of liver cancer patients, which can rapidly increase FLR in a short time-time period so that some patients can achieve surgical conditions, to obtain long-term survival. At present, there are a variety of two-step hepatectomy methods to increase FLR, and each has advantages and disadvantages.

摘要： 剩余肝脏体积（FLR）不足是制约部分肝癌病人行根治性手术的重要原因之一。二步肝切除术是在治疗肝癌病人的过程中逐渐发展的手术方式，能够在短期内快速增加FLR，使部分病人达到手术条件，以期获得长期生存。目前，增加FLR的二步肝切除术术式多样，且各有利弊。
