Prognostic factors of the outcomes of subtotal thyroid resection in graves disease

Abstract

The long-term results of subtotal resection of thyroid gland on 82 patients with Graves' disease were studied. There was analysed the influence of three factors on outcome at Graves' disease: volume of a thyroid gland before operation, morphological structure of thyroid tissue and volume of thyroid remnant. Outcomes of subtotal resection of thyroid gland were studied on the basis of thyrotropic hormone level of blood in 3, 6, 12 months, 2 and 3 years after operation. Based on research it has been established that the volume of thyroid gland before operation does not influence to outcome of subtotal resection of thyroid gland with Graves' disease. Morphological changes of removed thyroid tissue in the form of colloidal nodules at patients with Graves' disease statistically significantly raise risk of development of postoperative complications after subtotal resection of thyroid gland. The surgeon defining the volume of thyroid rem-nant durng the operation could be mistaken as towards it's increase so towards it's reduction, with an average deviation about 35%. Various outcomes of subtotal resection of thyroid gland at the same volume of thyroid remnant let us conclude that this out-come depends more on intensity of autoimmune process rather than on the volume of thyroid remnant. According modern views to aetiology and patogenesis of Graves' disease, the optimum volume of operation at Graves' disease is thyroidectomy.
