甲状腺肿瘤外科手术2228例临床分析

目的探讨甲状腺肿瘤外科治疗效果，总结甲状腺肿瘤的诊疗经验。方法回顾性分析1992年-2004年间2228例甲状腺肿瘤(2072例甲状腺良性肿瘤，156例甲状腺癌)的临床资料及随访结果。结果2072例甲状腺良性肿瘤中，术后喉返神经损伤4例，永久性喉返神经损伤率是0．1％，暂时性喉返神经损伤率为0．1％；55例复发行二次手术，复发率为2．6％。术后无甲状旁腺功能低下和出血。甲状腺癌156例，8例复发，3例死亡，直接法统计5年生存率为95．50k，(64／67)，Kaplan-Meier法统计5年生存率为98．0％。60例微小癌中无1例复发或转移，5年生存率为100．0％。156例甲状腺癌中1例喉返神经损伤，发生率为0．6％，术后无出血和甲状旁腺功能低下。结论遵循甲状腺肿瘤正确外科治疗原则能有效降低甲状腺疾病患者手术并发症、复发率等，并改善预后。

Clinical research on 2228 cases of thyroid gland tumors

Objective To discuss outcome of thyroid tumor patients treated with surgery. Methods~Total number of patients was 2228.These patients of thyroid tumors from 1992-2004(2072 cases of benign thyroid diseases and 156 cases of thyroid carcinoma) were recruited. The clinical and follow-up datum were retrospective analyzed. Results (1) Benign thyroid tumors with near-total thyroidectomy including 1761 thyroid adenoma ,207 nodular goiter and 104 Hashimotos thyroiditis, the incidence of recurrent laryngeal nerve paralysis was 0.2%, 55 cases(2.6%) received secondary surgery .All the patients have no hypocalcemia or hemorrhage after operation. (2) Eighty-one cases of papillary carcinoma of the thyroid (>1 cm) and 60 cases of microcarcinoma. Unilateral thyroidectomy, contralateral near-total thyroidectomy and ipsilateral modified neck dissection were performed in unilateral papillary carcinoma of thyroid. Among the 9 cases of follicular carcinoma of thyroid, 7 were performed of near-total thyroidectomy without neck dissection, others were the same as papillary carcinoma . Bilateral total thyroidectomy and bilateral modified neck dissection were performed in 2 cases of the medullary thyroid cancer and 1 case of the undifferentiated thyroid cancer. By direct method the 5-year survival was 95.5% (64/67), and by Kaplan-Meier method, it was 98.0%.The treatment of microcarcinoma are multiple. There is no relapse or metastases in 60 cases of papillary thyroid microcarcinoma. The 5-year survival was 100.0%, 1 cases occurred recurrent laryngeal nerve paralysis in thyroid cancer. No hypocalcemia or hemorrhage. Eight case relapsed in 156 cases of thyroid carcinoma,3 cases died. Conclusion The correct surgical management for the patients with thyroid tumor should benefit for the prognosis and reduce the complications and the recurrence of the operation.
