China is a “big country of liver cancer”, and the incidence of both primary and metastatic liver cancer remains high. Surgery is the most important means to treat liver tumors. However, liver surgery is traditionally regarded as a “huge invasive” surgery, with huge incision, long time and heavy bleeding, which leads to slow recovery and prolonged hospitalization, and creates great fear for many patients. In recent years, laparoscopic hepatectomy has developed rapidly in some large medical centers. Laparoscopic hepatectomy is “minimally invasive”, which can minimize intraoperative trauma and reduce the impact on liver function. Compared with open surgery, laparoscopic liver surgery has the advantages of shorter operation time, less intraoperative bleeding, less postoperative pain, etc., and there is no difference in perioperative complication rate and postoperative survival rate. In 2008, the world’s top liver surgeons held a meeting in Louisville, USA, and pointed out that the best indications for laparoscopic hepatectomy are: tumors in superficial parts of the liver, such as liver segments II-VI, and tumors with a diameter of less than 5 cm, because it is difficult to reveal tumors located in other segments of the liver, and the risk of tumor spread increases with a large diameter of tumors and tumor rupture during the operation. The risk of tumor dissemination increases. However, in recent years, with the application of advanced hemostatic devices such as energy platforms, intraoperative bleeding has been significantly reduced; supplemented by real-time ultrasound positioning and fluorescence imaging during the operation, tumors can be accurately localized and tumor margins can be effectively ensured, which makes laparoscopic liver surgery almost no “forbidden zone”. Therefore, in 2014, the world’s top liver surgeons held another meeting in Morioka, Japan, and published the “Expert Consensus on Laparoscopic Hepatic Resection” on the current status of laparoscopic liver surgery, technical points, and therapeutic efficacy. The consensus pointed out that globally, 31 hospitals have already completed more than 100 laparoscopic liver surgeries annually, and the proportion of laparoscopy has reached 10% to 40%; for experienced medical centers, the location and diameter of liver tumors are no longer the determining factors for laparoscopic surgery.
