<p><b>OBJECTIVE</b>To study the factors affecting the long-term prognosis of patients with myasthenia gravis (MG) after thymectomy.</p><p><b>METHODS</b>170 MG patients who had undergone thymectomies were studied retrospectively. Among them, 124 patients received long-term follow-up for more than 40 months postoperatively. The COX regression analysis model was used to analyze the factors that may influence the long-term prognosis. These factors included thymus pathology, patient gender, age, duration of disease at the time of surgery, preoperative Osserman classification and medication.</p><p><b>RESULTS</b>The research showed that thymus pathology was the single independent factor that affected the postoperative long-term prognosis. The long-term survival rates differed significantly with thymus pathological types: hyperplasia > benign thymoma > atrophy > malignant thymoma (P < 0.05).</p><p><b>CONCLUSION</b>The different pathological types of the thymus were the important factor affecting long-term survival in MG patients after thymectomy.</p>

Objective: To study the clinical therapeutic characteristics of myasthenia gravis (MG) with hyperthyroidism and the effects of surgical procedures for the patients. Methods:Subtotal thyroidectomy,thymectomy,and simultaneous subtotal thyroidectomy and thymectomywere performed on eleven patients with MG and hyperthyroidism. These patients were followedup after the operation. Results :The neck incisions were infected in two of seven type Ⅱ b patientsdue to trachestomy and the infected incisions were surgically healed. The MG symptoms of threecases (1 cases in type Ⅱ. and 2 cases in type Ⅱ b) relapsed in 3 to 6 months after subtotal thy-roidectomy. The MG symptoms of 2 cases (1 case in type Ⅱa and 1 case in type Ⅱ b) relapsed in 8to 12 months after thymectomy. Among six patients treated by simultaneous subtotal thyroidecto-my and thymectomy,the MG symptoms relapsed in a type I case 3 months after the operation,remitted in three case (1 case in type Ⅱ, and 2 cases in type Ⅱb) and improved in two type Ⅱ bcases since the operations. Conclusion:The simultaneous subtotal thymectomy and thyroidectomyfor patients with MG and hyperthyroidism might have better effects,although infective opportuni-ty of the neck incisions increased owing to trachestomy. However,the prognostic effects were notvery satisfactory whether simple subtotal thyroidectomy or thymectomy for the patients with MGand hyperthyroidism was performed.

Objective:To study the causes that resulted in delayed surgery for bronchial ruptures and the results.Methods:The cases with the bronchial ruptures by the delayed surgery last decade were retrospectively reviewed.The causes and unsatisfactory results were analysed.Results:The severe complications usually occurred after the delayed surgery and the results were not as satisfactory as those by early surgery.Conclusion:The bronchial ruptures ought to be operated in the early stage after being wounded.
