Hand sweating is a disorder in which the hands are locally sweaty due to abnormal sympathetic excitation. Patients with hand sweating can produce beads of sweat visible to the naked eye at the onset of the disorder, and in severe cases, they can drip down the fingers. The hand sweating disorder has a small impact on the physical health of the person, but it can have a big impact on life, work and social life, such as hand sweating disorder patients are not suitable for playing the piano, driving, bank tellers and other jobs, when shaking hands with others, hugging will also have concerns, and even in the relationship and dating and other aspects of the impact can not be ignored. Mr. Yang, who is just in his early 30s, is an example. Mr. Yang works in a foreign company and has just recently been promoted to manager of the public relations department, and he is both happy and worried after learning the news of the promotion. He was both happy and worried after learning the news of his promotion. He was happy because he finally got what he wanted under his unremitting efforts, but he was worried about the disease that had been plaguing him for 20 years, and whenever he was slightly nervous or excited, his hands would involuntarily break out in wet beads of sweat, and sometimes his hands would even sweat profusely, as if he had just gotten out of the water, which lasted at least 20 minutes each time to relieve. As a result of long-term severe sweaty hands, Mr. Yang was afraid to shake hands with others, affecting his normal work and life. After consulting several tertiary hospitals in Shanghai, Mr. Yang was referred to the thoracic surgery department of Shanghai Xinhua Hospital for treatment and was advised by Dr. Xiao Haibo, the deputy chief physician, to adopt a new minimally invasive surgery method via his belly button. His family was surprised to find that there were no obvious surgical scars on his entire body, and if he hadn’t reminded himself, others wouldn’t have been able to tell that he had had surgery. The traditional treatments for hand sweating include drug therapy, botulinum toxin blocking therapy, iontophoresis, transthoracic sympathectomy, etc. However, the effect of internal conservative treatment is not exact, and hand sweating symptoms tend to recur. At present, transthoracic bilateral sympathectomy is clinically recognized as the best treatment for hand sweating, but it has to be done through a surgical incision in the chest, and some patients will experience chronic pain in the wound after surgery, and although the chest scar is small, it is still difficult to be satisfactory for young patients. The navel is the natural orifice that connects the fetus to the mother during the embryonic period, and after birth it has no physiological function and becomes a natural “scar” that remains on the abdominal wall forever, which usually does not attract much attention. Single-port laparoscopic surgery via the umbilical approach is a scarless abdominal wall surgery technique that uses the umbilicus, the body’s natural “scar”, and local skin folds to cover the surgical scar, reducing incision-related complications, alleviating postoperative pain, and achieving a “scarless “It is the most feasible surgical technique via natural orifice at this stage. At present, the success rate of “transumbilical bilateral sympathectomy” adopted by Dr. Xiao Haibo for the treatment of hand sweating is 100%, and the patient can be cured after only one day of hospitalization. Compared with conventional thoracoscopic surgery, this procedure is less traumatic, less painful and quicker to recover after surgery, and the incision is more concealed and without obvious scar, achieving the perfect combination of minimally invasive and cosmetic. As shown in the picture, there is no scar on the patient’s chest after transumbilical bilateral sympathectomy, and the umbilical wound is very concealed.
