Objective: Explore smal cut half-cut line sternum thymus gland excision treatment and myasthenia gravis the surgical results and impact factors and 52 cases of surgery experience..Methods: 52 cases are made of a smal incision into the chest incision half sternotomy, removal of the thymus and al anterior mediastinal fat tissue, which has foreign invasion performers, the removal of the pleura, pericardium, arterial involvement of the outer membrane, and then typing of clinical symptoms, mirror under pathological type, clinical staging, whether radical resection were classified statistics remission, improvement, no change in the number of cases of deterioration, al eviate and improve as valid, no change and deterioration deemed invalid to valid and invalid cases the number of rows X2 test.Results:The group of 52 cases, the total efficiency of 82.7% (43/52), unchanged in 5 cases, 9.7%, deterioration of four cases, 5.8%, of which 1 died. The mean operative time 89.3 ± 24.7min (53min-176min), intraoperative bleeding 0 cases of vascular injury, al cases of intraoperative blood loss<200ml, postoperative drainage <200ml, 0 mediastinal infection, wound infection in 1 case (1.92 %), mean postoperative hospital stay 6.7 ± 3.8 days. There was no significant difference (P> 0.05) affect the clinical symptoms and microscopic pathology typing typing on the effect of surgery, there is a significant difference (P <0.05) clinical staging and radical surgical resection influence the effect.Conclusion: The clinical symptoms of type has some influence on the surgery, Ⅲ type efficiency decreased, but no statistical y significant difference in the impact analysis of the efficacy, suggesting regardless of clinical type, should be surgery, primary breast cancer is not easy to radical resection, but on surgical resection of myasthenia gravis symptoms, the differences between benign and malignant smal , Masaoka staging and prognosis of thymoma complicated by myasthenia gravis, between ⅰ, Ⅱ period, Ⅲ and Ⅳalso There were significant differences in order ⅱ best. Semi-sternotomy incision line thymus radical resection, shorter operative time, less blood loss, faster recovery, better than the traditional median sternotomy surgery, surgical results and reliable, suitable for primary hospitals.
