What preparations are needed for ultrasound-guided microwave ablation for liver cancer? Preoperative preparations for ultrasound-guided microwave ablation for liver cancer

In addition to traditional surgical resection and hepatic artery interventional embolization treatments for liver cancer, new methods invented in recent years include minimally invasive treatments represented by microwave, radio frequency, and argon-helium knife, drug targeted therapy represented by sorafenib, as well as biological immunotherapy and liver transplantation.

Among them, the most effective, safest, with the least side effects, the most economical, the simplest to operate and the shortest operation time is the cold circulation microwave ablation treatment technology. Ultrasound-guided percutaneous microwave ablation has great advantages in the treatment of space-occupying organs in the liver or other organs because of its real-time guidance and monitoring, precise positioning, complete ablation, no radiation, immediate inspection during surgery and repeated multiple times in a short period of time. Therefore, in recent years, it has been widely promoted and applied in the fields of liver cancer, kidney cancer, lung cancer, prostate cancer, thyroid cancer, gynecological tumors, etc., and even satisfactory results can be achieved for middle and late stage tumors.

Ultrasound-guided percutaneous microwave ablation has a wide range of indications. It is applicable to patients with primary liver cancer who do not have severe liver and kidney dysfunction or severe coagulation dysfunction, patients with recurrence after liver cancer resection, and patients with liver metastasis. Before undergoing ultrasound-guided microwave ablation for liver cancer, the following two preparations should be made:

1. Before treatment, patients should undergo routine blood tests, complete liver function tests, prothrombin time and activity tests. Patients over 50 years old should undergo electrocardiograms and chest X-rays. Patients with diabetes should have their blood sugar measured. Treatment should be started when these indicators are adjusted to a better state.

2. Patients are prohibited from eating or drinking on the day of treatment. An intravenous access must be established before treatment. It is usually performed under intravenous anesthesia, which requires close cooperation from an anesthesiologist. Small tumors in suitable locations can also be treated under local anesthesia.
