甲状腺单发结节

SOLITARY THYROID NODULE

本文旨在探讨２０２０例甲状腺单发结节术前诊断和治疗方法，术前核素扫描对治疗决策帮助不大。超声检查提示纯性囊性病变，直径小于４ｃｍ者很少是恶性，但囊性与实质性混合型可能是恶性，细针穿刺细胞学检查有助于诊断。１０％～３０％单发结节为恶性，宜作患侧腺叶全切除术，囊性与实质性混合结节可作腺叶大部分切除术或腺叶全切除术，但不宜作摘除术。

2020 operated cases of solitory thyroid nodule were evaluated with special referenceto preoperative diagnosis and treatment.Preoperative scintigraphy gave little useful infor-mation for decisions concerning treatment.Ultrasonography revealed that purely cysticlesions less than 4cm in diameter were scarcely malignant with the exception of thecystic and solid mixed type. Fine needle aspiration biopsy was very useful in preopera- tive diagnosis. Because the 10-30% solitary nodules were malignent,lobectomy was themethod of choic.For cystic and cystic-solid lesions,subtotal or total lobectomyshould be performed,and enucleation was contraindicated
