Résumé
OBJECTIVE: Ethanol injection under ultrasound (US) guidance has been proposed as an alternative to surgery in the treatment of recurrent benign thyroid cysts following aspiration. We aimed to set up a new procedure of ethanol sclerotherapy without US guidance for the treatment of pure thyroid cysts in order to make this useful treatment, available to more patients, more particularly when access to centers specialized in thyroid ultrasonography is limited. PATIENTS AND METHODS: Nine patients with recurrent large thyroid cysts following aspiration, and showing symptoms of compression and/or cosmetic complaints were treated by ethanol injection without US guidance and followed for up to 11 years. RESULTS: After ethanol injection, mean cyst volume was significantly reduced (9.9 +/- 13.6 vs. 31.3 +/- 34.1 ml, P=0.007) and the mean percentage volume reduction was 72.7%. A size reduction of the thyroid lesion more than 50% was achieved in eight of the nine patients (89%). Compressive symptoms and cosmetic complaints totally disappeared after sclerotherapy in all patients. During a mean follow-up of 48 months (ranging from 12 to 135 months), no recurrences were observed. The treatment was well tolerated with no major side effects. CONCLUSION: Non-US-guided ethanol sclerotherapy is a safe and "easy-to-use" procedure to treat benign thyroid cysts effectively. Because this new treatment does not need US-guidance, it can be performed by endocrinologists during outpatient visits. This new procedure may be useful in some areas, such as developing countries, where access to US examination is limited.
