What is the main common knowledge of laparoscopic hepatectomy

  Laparoscopic liver microwave curing treatment is the use of high-frequency electromagnetic waves, the energy of microwaves into thermal energy, that is, through the oscillation of polar molecules in the tissue, especially water molecules to heat liver tissue and tumor tissue, causing hyperthermia is the tissue coagulation, necrosis, so as to achieve the purpose of hemostasis.  I. Indications for laparoscopic microwave curettage of liver: 1. Patients with primary hepatocellular carcinoma whose liver function is adjusted to Child-Pugh grade A or B, and whose diagnosis is based on the above-mentioned criteria; 2. The number of tumors does not exceed 3; 3. The largest nodule diameter does not exceed 175px; 4. The lesion is confined to the liver, and there is no vascular cancer embolus, adjacent organ invasion or distant metastasis; 5. Informed consent. Those who voluntarily choose microwave curing treatment; 6. All cases were examined by ultrasound, CT and/or MRI and AFP quantitative detection; 7.  (2) contraindications to laparoscopic microwave curettage of the liver: (1) serious coagulation dysfunction, platelets <40×109/L, prothrombin time >30s, prothrombin activity <40%, no improvement after transfusion, hemostatic drugs and other treatment; (3) combined with other serious underlying diseases, including cardiovascular system diseases, respiratory system diseases, endocrine system diseases and neurological diseases, can not cooperate with the treatment; (4) the combination of other serious underlying diseases (4) Combined with other systemic tumors; (5) Age > 80 years old.  (3) Common complications after laparoscopic microwave curettage of the liver Fewer postoperative complications, more safe and reliable, and less intraoperative bleeding, reducing the damage to liver function after surgery.  Fourth, microwave curing assisted, laparoscopic liver resection advantages 1, effective in reducing bleeding, microwave curing hemostasis with no carbonization, small damage, hemostasis powerful features, can occlude the blood vessels below 0.3 cm. 2, the microwave does not produce smoke, which makes the surgical field more clear and clear, easy to operate. 3, the microwave coagulation band on the resection surface also has a barrier to prevent the spread of tumors. The coagulation zone should be used to prevent tumor cells from contaminating the abdominal cavity or the incision, which also effectively reduces the recurrence of distant cancer. 4. The liver has a special blood supply and is rich in blood flow, so it is routinely necessary to block the blood flow into the liver or the whole liver when cutting the liver, especially for large hepatocellular carcinoma and central hepatocellular carcinoma cases, whose symptoms are more obvious. The safety time of hepatic thermal ischemia is short, and some scholars believe that it is usually 20-30 minutes. If this time is exceeded, it can lead to serious impairment of liver function or even liver failure and surgical failure. As a result, surgery within the safe time sometimes seems to be short, and more difficult operations cannot be completed. Therefore, some liver cancers cannot be removed. After microwave coagulation, the liver section does not require mattress sutures, and the application of microwave curing hemostasis method to cut the liver, in the removal of the curing zone does not need to block the liver blood flow, cut to the depth of the beginning of the step-by-step blocking the blood flow into the liver or the whole liver blood flow to win ample operating time, which greatly shortens the liver ischemia time, not only simplifies the surgical operation and damage to liver tissue, so that the postoperative damage to liver function is reduced, but also can significantly improve the liver tumor resection rate. 5.Multi-center and multiple tumors can be resected at one time, and microwave in-situ curing is feasible if they cannot be resected, which has less damage, faster recovery, less complications, and multiple parts of multiple liver cancers can be resected at one time, making the surgery safer.
