【摘要】 目的研究左旋甲状腺素(L-T4)在预防结节性甲状腺肿术后复发作用。方法结节性甲状腺肿术后分服药组(口服L-T4)和未服药组,经3~7年随访,使用B超、CT等检查手段,分析口服L-T4及持续服药时间与术后复发的关系。结果术后服药组较未服药组复发率低,术后服药1年以上组较服药1年以内组复发率低。结论结节性甲状腺肿术后服药1~2年能降低复发率。更多还原

【Abstract】 Objective To study the role of L-T₄ in the prevention of the postoperative recurrence of multinodolar goiter.Methods After surgery,the patients with multinodolar goiter were divided into two groups:L-T₄ group and control group.The patients were followed up for a long time,examined by B-ultrasonic or CT.The relationship between L-T₄ and postoperative recurrence and that between administration duration and the postoperative recurrence was observed.Results After surgery,the recurrence rate in L-T₄ group was lower than control group.The recurrence rate in group of L-T₄ more than one year was lower than group of L-T₄ in one year.Conclusion Postoperative administration of L-T₄ for one to two years can reduce the recurrence rate of multinodolar goiter.更多还原
