Abstract

Aim: This study retrospectively evaluated the effects of treatment of benign mixed-type and spongy-type thyroid nodules with microwave ablation (MWA) and ethanol ablation (EA) therapies. The changes in volume obtained by ultrasonography and cosmetic scores were examined. The efficiency of both treatment methods was also compared by statistical analyses.

Methods: Between July 2015 and July 2020, archive scanning was performed for patients who underwent MWA and EA in the radiology clinic. As a result, 57 MWA and 55 EA patients were included in the study. Nodule volumes from before the treatment, 3 months, and 6 months after ablation treatment were noted for each case. Cosmetic scores for all patients were also examined.

Results: A statistically significant difference was found in the mean nodule volume at 6 months between MWA and EA, with MWA being more successful (p<0.05). The MWA technique also resulted in significantly higher mean cosmetic score reduction (p<0.05).

Conclusion: Minimally invasive approaches are increasingly adopted in the treat¬ment of benign thyroid nodules, and both MWA and EA are effective and safe treat¬ments techniques. The results show that MWA treatment leads to better cosmetic scores and nodule volume changes in patients with benign mixed-type and spongy-type thyroid nodules.

Mikrodalga Ablasyon ve Etanol Ablasyon Tedavisi Uygulanan Benign Tiroid Nodüllerinin Tedaviden Sonra Hacimsel ve Kozmetik Skorlama Değişikliklerinin Karşılaştırması

Abstract

Amaç: Bu çalışma geriye dönük olarak benign mikst-tip ve süngerimsi-tip tiroid nodüllerinin mikrodalga ablasyon (MWA) ve etanol ablasyon (EA) terapileri ve tedavi etkinliğini değerlendirmiştir. Ultrasonografi ve kozmetik skorlarla elde edilen hacim değişiklikleri incelendi. Her iki tedavi yönteminin etkinliği de istatistiksel analizlerle karşılaştırıldı.

Yöntem: Temmuz 2015 ile Temmuz 2020 tarihleri arasında radyoloji kliniğinde MWA ve EA yapılan hastalara arşiv taraması yapıldı. Sonuç olarak 57 MWA ve 55 EA hastası çalışmaya dahil edildi. Her vaka için tedavi öncesi, ablasyon tedavisinden 3 ay ve 6 ay sonraki nodül hacimleri not edildi. Tüm hastalar için kozmetik skorlar da incelendi.

Bulgular: MWA ile EA arasında 6. ayda ortalama nodül hacminde istatistiksel olarak anlamlı bir fark bulunmuş olup, MWA daha başarılıydı (p<0.05). Ayrıca MWA tekniği, anlamlı olarak daha yüksek ortalama kozmetik skor azalmasıyla sonuçlanmıştır (p<0.05).

Sonuç: Minimal invaziv yaklaşımlar, benign tiroid nodüllerinin tedavisinde gider-ek daha fazla benimsenmektedir ve hem MWA hem de EA etkili ve güvenli teda-vi teknikleridir. Sonuçlar, MWA tedavisinin benign mikst-tip ve süngerimsi-tip tiroid nodülleri olan hastalarda daha iyi kozmetik skorlara ve nodül hacim değişikliğine yol açtığını göstermektedir.
