    Abstract:
    UNLABELLED: Myasthenia gravis (MG) is a chronic autoimmune disease that usually responds positively to treatment with thymectomy. Standard surgical procedures have been shown to result in a favorite outcome. The optimal surgical access, however, is under discussion. PATIENTS AND METHOD: In a prospective study conducted between 8/97 and 4/05, 173 patients with MG underwent thoracoscopic thymectomy, for which a left-sided approach was generally applied. An analysis of the intraoperative and postoperative course was performed in 137 patients (8/97 and 12/03), as well as of the impact of the surgical procedure on further development of the disease. The results obtained were compared with those published in the literature, with particular reference to results obtained with open surgery. In 8 patients, the procedure was converted to an anterolateral thoracotomy or sternotomy, so we examined 129 patients, which were operated thoracoscopically. RESULTS: The patients in this study were 93 females and 36 males, with a mean age of 35.8 (range: 9-83) years. The mean preoperative duration of the disease was 22.9 (range: 1-140) months. The duration of operation was 50 to 85 minutes, the blood loss was lower than 100 ml. The mean follow up was 24.7 (range: 1-57) months. Complete remission was noted in 30 patients (23.3 %), and improvements reflected either in a reduction of the required medication, or a decrease in symptom severity, were seen in a total of 86 patients (66.6 %). CONCLUSION: Complete thoracoscopic thymectomy is a technically feasible operation, and as effective as conventional open surgery. Remissions or symptomatic improvements were observed in more than 89 % of the patients. The low morbidity rate, in combination with excellent cosmetic results, has led to increasing acceptance of the operation both by patients and neurologists. Therefore, thoracoscopic thymectomy represents a new, alternative method for treatment of patients with MG.
