About
The extent of thyroid resection in Graves' disease remains controversial. The aim of this study was to evaluate long-term results of bilateral subtotal thyroidectomy versus total thyroidectomy in patients with Graves' ophthalmopathy.
Full description
Graves' disease was first described in 1835. It is an autoimmune disorder caused by antibodies which bind to thyroid-stimulating hormone (TSH) receptors on the thyroid cell membrane. The overt clinical manifestation of this disease is usually characterised by presence of hyperthyroidism, thyroid associated ophthalmopathy and thyroid dermopathy.
Treatment alternatives of Graves' disease include antithyroid medication, radioiodine therapy or thyroidectomy. The antithyroid medication is often used as the initial treatment for patients with newly diagnosed Graves disease in much of the world including Europe, Japan and South America. However, the use of radioiodine is the most common first-line treatment modality in the United States. Thyroidectomy should be considered in special circumstances such as in children and young adults, pregnant women, in the setting of ophthalmopathy, in the presence of thyroid nodules or big goitre, particularly when compressive symptoms, or substernal thyroid extension is diagnosed, as well as in cases of failed hyperthyroidism remission after antithyroid medication in patients refusing possible radioiodine treatment.
The surgical management of Graves' disease remains controversial. Some authors support total thyroidectomy while others prefer various subtotal procedures. Most low-volume surgeons avoid performing total thyroidectomies for Graves' disease owing to the assumed higher complication rates. On the other hand, an increasing number of total thyroidectomies are currently performed in high-volume endocrine surgery units, and the indications for this procedure include not only high-risk thyroid cancer, but also Graves's disease and multinodular goiter. It has been shown that total thyroidectomy for Graves' disease lowers to almost zero the disease recurrence rate. However, other issues like unclear benefit for natural course of Graves' ophthalmopathy balanced against assumed higher risk of morbidity following more radical thyroid resections need to be clarified.
We hypothesized that total thyroidectomy is superior to bilateral subtotal thyroidectomy for long-term control of Graves' disease. The aim of this study was to evaluate long-term results of bilateral subtotal thyroidectomy versus total thyroidectomy in patients with mild and active Graves' ophthalmopathy.
