Objective To investigate the association between preoperative serum TSH concentration and thyroid carcinoma in patients with nodular goiter.Methods Data of 632 patients with nodular goiter from January 2004 to December 2010 were analyzed retrospectively.Results Preoperative serum TSH in nodular goiter with thyroid carcinoma was higher than that without thyroid carcinoma，which was （2.10±1.38）mU/L and （1.51±0.98）mU/L，respectively （P＜0.000 1）.The risk of malignancy increased as serum level of TSH rose in nodular goiter patients （P=0.023 5），the ratios were 9.91% （0.3-0.9mU/L），12.37% （0.9-1.7mU/L）， 20.09% （1.7-4.8mU/L），and 27.27%（＞4.8mU/L）.The TSH level of stageⅢ-Ⅳ patients higher than that stageⅠ-Ⅱ patients （P=0.030 6）.The diameter of tumor ＞4 cm had highest mean TSH level， and which ≤ 2cm had lowest mean TSH level（P=0.018 6）. Conclusion Preoperative serum TSH level perhaps is a risk predictor for nodular goiter with thyroid carcinoma.
目的探讨结节性甲状腺肿合并甲状腺微小癌的临床特征、诊断、治疗原则及预后。方法回顾分析2003年1月至2010年2月期间在我科手术治疗的34例结节性甲状腺肿合并甲状腺微小癌患者的临床资料。结果 病理诊断乳头状癌33例，滤泡状癌1例。行患侧叶全切除术+峡部切除术+对侧叶次全切除术+患侧中央区淋巴结清扫术3例，1例加行患侧改良性颈部淋巴结清扫术; 患侧叶全切除术+峡部切除术+对侧叶次全切除术22例; 患侧叶全切除术+峡部切除术1例; 甲状腺全切除术8例。2例患者出现术后低钙血症，1周后恢复正常，无其他手术相关并发症发生。随访3个月至5年(平均20.2个月)，无一例复发或死亡。结论 甲状腺多发结节有恶性的可能，B超有助于诊断。手术方法多为患侧叶全切除术+峡部切除术+对侧叶次全切除术，预后较好。
目的 探讨甲状腺手术方式和喉返神经损伤（RLN）的关系。 方法 回顾性分析2009年1月至2012年6月期间于笔者所在医院科室接受开放性甲状腺手术的985例患者的临床资料，探讨甲状腺手术方式和RLN损伤的关系。 结果 本组患者术后发生RLN损伤26例（2.6%），未发生RLN损伤959例（97.4%）。logistic回归分析结果显示，年龄、性别、超声刀应用、麻醉方式及肿块良恶性与RLN损伤均无关（P＞0.05），而手术范围（OR=3.726，P=0.007）和显露RLN（OR=0.302，P=0.006）则是RLN损伤的影响因素，行扩大性手术及未显露RLN者的RLN损伤率较高。 结论 在开放性甲状腺手术中，手术范围以及显露RLN是RLN损伤的独立影响因素，术中显露并注意保护RLN，对避免RLN损伤具有重要意义。
Objective To explore the relationship between external branch of superior laryngeal nerve (EBSLN) injury and the approachs of surgery in open thyroidectomy, and to summarize the preventive methods. Methods The clinical data of 985 patients who had consecutively underwent open thyroidectomy from January 2009 to June 2012 were retrospectively analyzed, to explore the relationship between EBSLN injury and the approachs of surgery in open thyroidectomy. Results The overall incidence of EBSLN injury was 2.6% (26/985), and 959 patients (97.4%) didn’t suffered from EBSLN injury. Results of logistic regression showed that the extent of surgery (OR=4.536, P=0.004) and identification of the EBSLN (OR=0.126, P=0.044) were influence factors of EBSLN injury after open thyroidectomy, but age (OR=1.108, P=0.823), gender (OR=0.604, P=0.260), benign or malignant tumor (OR=1.871, P=0.186), anesthesia methods (OR=0.659, P=0.372), and the application of ultrasonic scalpel (OR=0.473, P=0.248) were not associated with EBSLN injury. Conclusion In open thyroidectomy, the extent of surgery and identification of EBSLN are the independent factors of EBSLN injury, which are important to avoid EBSLN injury.
