As a rare disease, myasthenia gravis is often misdiagnosed and poorly understood by society, many patients lack confidence or even give up treatment, thus missing the best time for recovery. If the disease is detected early, the cause is identified and treated appropriately, about 30% of patients can get rid of the disease and resume a normal life after treatment. This is what the reporter learned from the national conference on new advances in the diagnosis and treatment of thymoma and myasthenia gravis, which was carried out in Tianjin last weekend and hosted by the Department of Thoracic Surgery of Tianjin Medical University General Hospital. According to Professor Zhang Peng, director of thoracic surgery at the General Hospital, myasthenia gravis is an autoimmune disease whose onset is closely related to thymoma or thymic hyperplasia, with a prevalence rate of about 1/5000 and an increasing trend in recent years. The incidence of the disease is higher in women than in men before the age of 40 (male: female 3:7), the incidence of men and women is equal between the ages of 40 and 50, and the incidence of men is slightly higher than that of women after the age of 50 (male: female 3:2). Most people start with eyelid weakness and drooping. Without early and effective treatment, 80% of patients with myasthenia gravis will progress to other muscle groups and the medulla oblongata within a few months or two years, and then transform into generalized myasthenia gravis, which can seriously affect life and work, and even endanger life. ”Early surgical removal of thymic lesions is the most likely treatment to cure myasthenia gravis.” Zhang Peng said, the traditional thymectomy need to “open the chest and break the bone”, the hospital in the city pioneered the thoracoscopic thymectomy minimally invasive surgery, without opening the sternum, trauma, fast recovery, complications greatly reduced.
