Hand sweating is caused by an abnormal increase in sweating from the palms of the hands due to tension, excitement, stress, or sympathetic hyperactivity during the summer heat. Most patients have a cold sweat on their hands throughout the year, especially when they are emotionally stressed, and the sweat beads are constantly oozing, sometimes so much that they drip. The skin of both hands is often cold and wet, and may be pale or greenish-purple. Patients may be afraid to shake hands or hold hands with others because of wet hands, and they may write and wet paper due to excessive sweating, or they may wet the keyboard when operating a computer. These inconveniences often make the patient feel embarrassed. In severe cases, the patient may suffer from low self-esteem or autism, causing great distress to the patient’s life, study and friendships. Hand sweating can be temporarily relieved by medication, but its effects are short-lived and have side effects that make patients afraid or unwilling to use it for long periods of time. In recent years, television thoracoscopy has been used to treat hand sweating by cutting or clamping the thoracic sympathetic nerve chain, and our hospital has been the first in the region to successfully perform this procedure. The procedure requires only a small incision of 5 mm in each axilla of the patient, and under the precise guidance of the thoracoscope, the thoracic sympathetic nerve chain that causes hand sweating can be cut accurately and quickly in only 30 minutes using the TV surveillance system, thus achieving the purpose of treating hand sweating. The effect of the procedure is immediate, and within minutes after the procedure, the patient’s hand sweating symptoms disappear, and the skin of his or her hands immediately becomes warm and dry, and he or she can be discharged from the hospital 2 days after the procedure. Because of its advantages of small trauma, almost no bleeding, hidden incision, beautiful appearance, fast recovery after surgery, exact efficacy and very low recurrence rate, it has become the most ideal, effective and safe surgical procedure for treating hand sweating at home and abroad, and has been accepted by most patients. The TV thoracoscopic minimally invasive technique easily treats “hand sweating” and helps patients to get rid of the worry and shadow of excessive hand sweating and participate in the modern competitive life with a more positive attitude and confidence.
