Thyroid disease! Treatment and examination depend on "it"

Thyroid thermal ablation, ultrasound combined with radiofrequency ablation or sea knife are the mainstream of minimally invasive surgery at present.

Thyroid nodule refers to a lump in the thyroid gland, which can move up and down with swallowing. It is a common clinical disease, and the incidence rate of women is higher than that of men. When the patient is suspected to have thyroid nodules, an ultrasound examination will be arranged. The doctor pointed out that with the progress of medical technology, ultrasound has developed from physical examination to an effective tool for treating tumors. It can be combined with other minimally invasive interventional treatments to make tumor treatment completely non-invasive, which is an important role in treating thyroid nodules.

Prevention of tumor metastasis by thermal ablation of thyroid gland

Wang, the attending physician of the Department of Otolaryngology, Guotai General Hospital, said that thyroid thermal ablation is a noninvasive treatment of thyroid nodules under ultrasound guidance, mainly including microwave ablation, radio frequency ablation and laser ablation. Among them, the basic principle of radiofrequency ablation is to destroy tumor tissue by using heat energy, and the ions and polar macromolecules in the surrounding tissue oscillate and collide with each other to generate heat, heating the tumor area to the effective therapeutic temperature range and maintaining it for a certain time to kill tumor cells; At the same time, the thermal effect of radio frequency can also coagulate blood vessels in surrounding tissues, making them unable to supply blood to tumors and preventing tumor metastasis.

Ultrasound combined with radiofrequency ablation in the treatment of tumor

Nowadays, high-resolution ultrasound can clearly display thyroid nodules with a diameter of 2 mm Dr. Wang Hongwen introduced that during radiofrequency ablation, under the guidance of ultrasound, we can clearly see the irregular echo enhancement changes at the needle tip, and we can roughly judge the final range of tissue coagulation and necrosis to confirm the scope of surgery; In addition, the RF needle is very slender and will not leave scars on the neck, which is simple and time-saving. However, for the tumor close to the thyroid capsule, because it is close to the carotid artery, recurrent laryngeal nerve and parathyroid gland, the operation is often cautious and the treatment is easy to be incomplete.

At present, more than 50 cases have been successfully treated without serious complications, and the average volume can be reduced by 6 1% in the first 6 months.

Ultrasound cauterization of tumor with sea knife has little trauma.

Another important role in the treatment of thyroid tumors is HIFU. Dr. Wang pointed out that ultrasound will be used to locate the lesion first, and then the expected cauterization path will be calculated by the computer, and then the machine can automatically perform the operation. The machine will increase the intensity of ultrasound for examination, focus on the location of the tumor, and burn the lesions in turn on the same plane. By constantly changing the burning position, the whole three-dimensional lesion can be treated to complete the operation. Dr. Wang shared that haifu knife treatment will not leave any wounds on the body, nor will it destroy normal tissues outside the focus; In addition, it is also used abroad to treat parathyroid hyperplasia and tumors, which will be a great boon for renal dialysis patients.
