Some time ago, several young patients with myasthenia gravis came one after another, one of them, a 16-year-old boy from Yiwu, was very shy, his eyelids were drooping and could not open completely, his parents were anxious and helpless. This child, who has had myasthenia gravis for almost ten years, has been taking hormones and bromipyridamole for a long time, and also taking traditional Chinese medicine, and has spent more than 300,000 yuan, but the amount of medicine still has not been reduced. autism, etc. Physiologically, if the symptoms worsen, there will be difficulty swallowing and breathing, and in severe cases, life-threatening tracheal intubation is required. This little boy had difficulty breathing after a cold last New Year’s Eve and went to the hospital to be intubated in the ICU. Indeed, the birth of this disease is very unfortunate, although not a terminal disease, but the pain of which ordinary people can not imagine. The boy’s parents even had the intention of having another child despite his advanced age. The neurology department of our hospital is famous in the province for the treatment of myasthenia gravis, but the internal treatment sometimes has some limitations. Therefore, for some patients who do not heal for a long time or whose medical treatment is not effective, they are recommended to come to our thoracic surgery department for surgical treatment. After I introduced our surgical approach and treatment results to the patient’s parents in detail, they decided to have surgery without any hesitation. Our surgery is a minimally invasive approach: thoracoscopic total thymectomy. Studies have confirmed that there is a strong link between the occurrence of myasthenia gravis and thymic hyperplasia. Removal of the thymus gland can significantly improve the symptoms of myasthenia gravis, and the results can be so good that it can be cured completely without medication. Moreover, the surgery is very invasive, requiring only three small incisions of 0.5-1 cm in the chest wall to perform an enlarged thymectomy. The cost is also very economical because just having a thoracoscope is sufficient, no other materials are needed, and the postoperative recovery is quick. The boy recovered quickly after the surgery and was discharged on the 6th day. Yesterday his parents brought him back for a follow-up appointment. The strength of the boy’s limbs increased significantly, and the biggest change was that his eyelids did not droop anymore, and his face showed a big smile, which his parents said was long overdue. Now one month after surgery, the hormone dosage has been significantly reduced, and in another month the hormone can be completely stopped. The amount of bromipyridamole is also half of the amount before surgery, and it can be stopped in a few months. Minimally invasive extended thymectomy is indeed a boon to patients with myasthenia gravis. Recently, our thoracic surgery department and neurology department have joined hands to cooperate closely in the diagnosis and treatment of myasthenia gravis, including preoperative preparation, perioperative medication and postoperative management and medication reduction, and long-term postoperative outpatient follow-up to ensure good results in the treatment of myasthenia gravis.
