[Surgical treatment of myasthenia gravis and its evaluation]

30 cases of myasthenia gravis (MG) were treated with thymectomy. Before and after operation, peripheral blood lymphocyte subpopulation was determined in 10 cases and acetylcholine receptor antibody titer was determined in 6. The results confirmed the efficacy of thymectomy in treating MG. We suggest that application of hormone for regulating immune function of the body and/or plasma exchange for alleviating symptoms in patients with generalized MG before and after the operation. The results of treatment did not correlate with age, sex, length, and course of the disease. Radical operation, proper anaesthesia and appropriate antibiotics may ensure a smooth operation and high curative effect.
