Laparoscopic hepatectomy used to be regarded as a kind of highly difficult surgery, but along with the development of laparoscopic technology and various liver-cutting instruments, it has been gradually promoted in the past ten years, and has been widely used in the resection of hepatocellular carcinoma in all parts of the body, and for hepatocellular carcinoma located in the left outer lobe, laparoscopic resection, as the gold standard of its treatment, has been recognized by experts in the field. However, for many patients and their families, when doctors tell them that laparoscopic surgery or minimally invasive treatment is possible, whether minimally invasive surgery or open surgery, it is a means of treatment, and our main goal is to completely remove the tumor to achieve the goal of radical treatment. Cutting the tumor cleanly is the first requirement and the primary goal of minimally invasive surgery, otherwise we have to switch to open surgery. From the available reports, the recurrence rate of laparoscopic surgery patients is comparable to that of open surgery, in other words, laparoscopic surgery can achieve the same radical effect as open surgery.
