Thymus is an important immune organ in human body, which is related to many immune diseases such as dry syndrome and systemic lupus erythematosus, but few people know its importance. The day before yesterday, the second national continuing education course on new advances in the diagnosis and treatment of thymoma, sponsored by the Department of Thoracic Surgery of the General Hospital of Tianjin Medical University and the Thoracic Surgeon Branch of the Tianjin Medical Association, was held in Tianjin, and experts on the spot answered various questions about the thymus. ”Tumors of thymic origin, called thymomas, are more common in Asians.” Experts from the hospital’s thoracic surgery department introduced that thymoma often has no obvious symptoms in its early stages, but can lead to a variety of autoimmune diseases such as myasthenia gravis, pure red blood cell aplastic anemia, systemic lupus erythematosus and dry syndrome. How can thymoma be detected early? In addition to regular checkups, if there are pressure symptoms such as breath-holding, heartburn, facial edema, chest discomfort, etc., you should pay attention to them and seek medical attention as soon as possible. As for the treatment of thymoma, experts say that compared to the traditional “open-heart surgery”, nowadays minimally invasive thoracoscopic surgery can be done with only 3 incisions of less than two centimeters in the lateral chest, which not only has a short operation time and less bleeding, but also is less painful and has fewer postoperative complications. Usually, patients can be discharged within 1 week after surgery, and the results are remarkable.
