How exactly does minimally invasive surgery work? The operation is usually performed by puncturing the first hole below the navel (one finger below the umbilicus) and filling it with carbon dioxide to form a pneumoperitoneum to expand the operating space. After the laparoscope is connected, the liver lobe is observed, and then the auxiliary operating holes are punctured at the subcostal margin of the glabella and the left or right midclavicular line. It is through these holes that the operating instruments enter the abdominal cavity and complete the delicate operation. The entire procedure can be observed and handled in real time by the surgeon through the screen. What are the advantages of minimally invasive surgery? Compared with open surgery, laparoscopic hepatic hemangioma resection is a treatment option worth taking, and the specific advantages are as follows: 1. 2. High clarity of intraoperative vision ensures successful separation and fast hemostasis, which provides conditions for rapid recovery. 3. Postoperative infection is less likely to occur and hospitalization time is significantly shortened, which can reduce the treatment cost and burden of patients. Since there are many advantages of minimally invasive treatment, is it possible for every patient to use minimally invasive treatment? The requirements for minimally invasive treatment include the following: 1. Good general condition, able to tolerate surgery, and no history of abdominal surgery. 2. The location of the hemangioma is superficial and easy to operate, such as tumors located in segments II, III, IVB, V and VI of the liver. The main contraindications are: huge tumor, liver hemangioma combined with cirrhosis, abnormal coagulation function and history of abdominal surgery with serious abdominal adhesions. Patients can choose according to their own situation and doctor’s recommendation as appropriate.
