Hand Sweat Disorder, refers to the sweat of the hands obviously seriously affects a person’s normal life, in fact, this is often a pathological state. Because of the serious sweating of the palms of the hands and do not dare to shake hands with others, or ashamed to hold hands with lovers; exams when the sweat of the hands wet the paper; operating the computer when the sweat wet the keyboard; …… where this is the distress of such friends. In recent years with the improvement of people’s living standards and quality of life requirements, the number of people who take the initiative to seek medical treatment for sweaty hands is increasing. Bilateral palms are noticeably sweaty Most cases of hyperhidrosis have no clear cause. Traditional treatments include psychotherapy, sedation, treatment with anticholinergic receptor drugs, Chinese herbal medicine, topical skin astringents, and so on. However, all of these treatments have not had a very definite therapeutic effect. As early as 1920, doctors have known to use “sympathetic ganglionectomy” to treat hand sweating. However, due to the special anatomical location of the sympathetic nerve structure, at that time, the operation could only be accomplished by means of open-heart surgery, which was obviously very traumatic. Therefore, this method was not widely accepted by patients and doctors. It was not until the 1990s that the advent of television thoracoscopy brought a revolutionary breakthrough in this surgical method. Through a small incision of 1cm in the chest wall and the insertion of a TV thoracoscope, the sympathetic nerve chain adjacent to the spine can be clearly visualized, and the sympathetic nerves can be easily severed with some special instruments. The operation of thoracoscopic surgery is described as follows: The patient is hospitalized for a short period of 2-3 days and the necessary tests are done before the operation. General anesthesia is used. The patient sits in an upper body slanting position. First, a small incision of about 01cm is made in a hidden position under the armpit of one side of the chest wall, and a thoracoscope is placed into it, allowing the surgeon to see the inside of the thoracic cavity as well as the sympathetic nerve chain, which is located next to the spine and parallel to the spine, through a TV screen. Then, using special instruments, the surgeon can cut the sympathetic nerve chain in about 5 minutes. After the operation on one side, the other side is operated in the same way. The total operation time is less than half an hour. The patient can go down to the ground in the afternoon of the day after the operation. The patient can be discharged from the hospital the next day. The patient will be able to return to work within a week at the longest. There is virtually no scarring of the chest wall after the stitches are removed. Thoracoscopic visualization of the thoracic sympathetic chain Small incisions under the armpit The improvement rate of hand sweating can reach 98-100%, and since the trauma is very small, the procedure is generally safe. Regarding surgical complications, the most frequent is compensatory sweating in other parts of the body, but less than 10% of patients with this condition are bothered or regret the surgery.
