What is the difference between minimally invasive rotary excision and minimally invasive ablation of breast nodules?

At present, minimally invasive surgery for breast nodules has two techniques: rotary cutting and thermal ablation.

Both minimally invasive rotary excision and minimally invasive ablation of breast nodules are performed under the supervision and guidance of ultrasonic instruments, so as to achieve real precision and minimally invasive.

Minimally invasive rotary excision of breast nodules requires a small incision of about 4 mm on the skin. The key consumable used is a rotary needle with a thickness of about 4 mm. Under the guidance of ultrasound, the rotary needle is placed behind the nodule, and the needle groove at the front end of the rotary needle is opened to cut the nodule and a small amount of glandular tissue around it into strips, which are sucked out of the body through negative pressure suction. After operation, the local elastic bandage was pressed for 48 hours, and heavy physical labor was not allowed for two weeks.

The key consumables for minimally invasive ablation of breast nodules are ablation needles. At present, there are mainly three types: RF, microwave and laser. RF ablation needles are widely used, with a thickness of about 1 mm, and the three ablation principles are similar. They all use a thin ablation needle to pierce the nodule through the skin. The needle tip can heat the surrounding tissues and cauterize the nodules with heat. There is no incision in the skin, and there is no need for local compression after operation. After being burned, the nodules will gradually shrink or even disappear completely.

At present, minimally invasive breast rotary ablation is mainly used for benign breast nodules. For breast malignant nodules, surgical resection is usually used. Of course, some scholars are exploring the application of rotary resection and ablation in breast malignant nodules. Some studies believe that ablation can be directly used to inactivate tumors for smaller breast cancers. Or the tumor can be ablated first, and then the tumor can be removed by rotary resection, which can reduce the probability of distant metastasis caused by surgery.
