Percutaneous ethanol injection in treatment of benign nonfunctional and hyperfunctional thyroid nodules.
In recent years a new method of treatment of thyroid disorders, percutaneous ethanol injection (PEI), has been successfully used as an alternative to surgery for the management of benign nodules. In this study 103 females and 5 males (34.4 +/- 11.3 yrs) with nonfunctional cystic (23) or solid (38) nodules, and also 47 with hyperfunctional solid nodules, were treated with single or repeated ethanol injections. In all patients, the cytological studies, ultrasound evaluation and the levels of free triiodothyronine (fT3), free thyroxine (fT4), and thyrotropin or thyroids-stimulating hormone (TSH) before and after ethanol administration, were determined. The patients were followed up for 12-36 months. The size of the benign nonfunctional nodules was totally reduced in 49.9% of cases with solid and in 60.9% of patients with cystic nodules. Hyperthyroidism was cured in 91.5% of patients. The PEI procedure was connected with a few significant complications only, in relation to the localization of nodules. It was cheap, possible on an outpatient basis, easy to perform and acceptable to patients. Since the cost of thyroidectomy is high and the complication rate significant, PEI is a suitable substitute treatment especially for some patients with small toxic benign nodules of the thyroid gland.
