Ms. Li, 32 years old, recently felt discomfort in the liver area all the time, and found a 5*5cm tumor on the diaphragmatic surface of the right liver in the hospital. According to the imaging examination, the preoperative diagnosis was focal nodular hyperplasia of hepatocytes. The surgical incision was 25cm long, the trauma was huge, the recovery was slow, and there were many complications, such as intestinal adhesion, abnormal sensation of the abdominal wall, and decreased abdominal muscle tone. The patient is a young woman who loves beauty and has not married and had children, so this surgery is not a disaster for her, although it can cure her physical disease, but at the same time, it will bring her psychological distress for a long time. So we decided to use laparoscopic minimally invasive surgery, 5 small holes in her abdominal wall, the use of ultrasonic scalpel, the use of titanium clips complete resection of the right liver tumor, through the umbilicus to remove the tumor, the operation was very smooth, bleeding less than 100ml, abdominal wall only a few small holes, 1 day after the operation can get out of bed activities, eating, Ms. Li cried with joy. Mr. Zhang is another patient who benefited from the laparoscopic technique. He is a retired teacher and is 70 years old. He was a retired teacher who was 70 years old and paid close attention to regular medical checkups because he was a Hepatitis B carrier. Recently, he was found to have a 5*5cm liver cancer in the outer lobe of his left liver, and we performed laparoscopic surgery on him, removing the left outer lobe of his liver, with only 3 holes in his abdominal wall and a 5cm long incision (for complete removal of the tumor), which resulted in the rapid recovery of the patient’s health. From these wonderful cases, we can see that laparoscopic technology has successfully landed in liver surgery, transforming the traditional giant invasive liver tumor resection into a minimally invasive surgery, reducing bleeding and common postoperative complications, and patients have gained very great benefits. However, laparoscopic hepatectomy requires a very high level of skill from the surgeon, because to perform this surgery, firstly, the surgeon is required to have a wealth of experience in open liver resection, as well as exquisite laparoscopic techniques, and then laparoscopic hepatectomy is relatively expensive, because the surgery will use more consumables, such as: hair-linking titanium clips, vascular cutting sutures, ultrasonic knives. As a result, this type of surgery is not yet widely available and is only performed in the liver specialties of some large hospitals. Of course, not all liver tumors can be suitable for laparoscopic surgery, if the tumor is located in the left outer lobe, the surface of the right liver section 5 or 6 is the best indication. If the tumor is too large, located in the center or back of the liver, closely related to the hepatic hilum, or with large blood vessel compression or invasion, it is better to choose traditional surgical treatment.
