摘　　要：目的探讨高分化型甲状腺癌再手术的原因和再手术时肿大淋巴结转移的危险因素。方法回顾性分析昆明医学院第一附属医院普通外科1998-2005年收治的54例行颈淋巴结清扫高分化型甲状腺癌再手术患者的病历资料。结果39例不规范手术后的甲状腺残癌率和淋巴结转移率均显著高于15例根治后的患者（P〈0．05）。再手术时患者年龄〈45岁、首次手术前同侧颈部淋巴结肿大、同侧癌灶残留或复发、原发癌的多中心性和再手术时B超提示淋巴结皮髓质分界不清等是再手术时同侧肿大淋巴结转移的危险因素（P〈0．05）；原发癌的多中心性和对侧癌灶的出现，是再手术时对侧肿大淋巴结转移的危险因素（P〈0．05）。结论首次手术的个体化的规范根治和必要的颈部淋巴结清扫是避免高分化型甲状腺癌复发再手术的关键。再手术时应行全甲状腺切除，对有淋巴结转移危险因素的患者，应行改良性或选择性区域颈淋巴结清扫。Objective To investigate the cause of reoperation for high differentiated thyroid carcinoma and the risk factors of neck lymph node metastasis in reoperation. Methods Retrospectively reviewed the clinical data of 54 high differentiated thyroid cancer patients from 1998 to 2005, who received reoperation and neck lymph node dissection simultaneously. Results The residual thyroid carcinoma rate and lymph node metastasis rate were higher in 39 patients who initially received partial thyroidectomy than in 15 who previousely underwent radical operation （P 〈 0. 05 ）. Age less than 45 years, lymphadenectasis before initial operation, tumor residued or relapsed, multicentficity of primary cancer and blurred boundary between cortex and medulla of lymph node were the risk factors for ipsilateral lymph node metastasis（ P 〈 0. 05 ） , while mul- ticentricity of primary cancer and eontralateral thyroid cancer were the risk factors for contralateral lymph me- tastasis （ P 〈 0. 05 ）. Conclusions Individual standard radical operation and necessary lymph node dissection are important measures to prevent recurrence and reoperation. Completion thyroidectomy and modified or selec- tive neck dissection are recommended for reoperation patients with the risk factors of lymph node metastasis.
