Abstract
in English, Chinese

Objective:A prospective randomized controlled study of patients with thyroid papillary carcinoma requiring lateral neck dissection was conducted to investigate the thoroughness, safety and cosmetic features of endoscope-assisted lateral neck dissection. Method:Patients who underwent total thyroidectomy, bilateral central lymph node dissection and unilateral lateral neck dissection for papillary thyroid cancer were randomly divided into two groups: endoscopic assisted group and open group, 18 cases in each group. The clinical characteristics, operation conditions, postoperative complications and aesthetic satisfaction of the two groups were compared. Result:There were no statistically significant differences between the endoscopic group and the open group in age, gender, tumor size, dissection side, operation time, postoperative hospital stay, number of lymph nodes to be dissected, number of metastatic lymph nodes, postoperative hoarseness, and hypoparathyroidism（P>0.05）; No hematoma or lymphatic leakage occurred in the two groups after surgery, and no tumor recurrence or residual was found in the ultrasound review at 6 months after surgery. Serum Tg level in the endoscopic group was higher than that in the open group at 6 months after surgery, but the difference between the two groups was not statistically significant（P>0.05）; The neck pain score at day 3 after operation, the neck numbness and discomfort score at month 1 after operation, and the aesthetic satisfaction score at 3 months after operation in the endoscope assisted group were better than that in the open group（P<0.05）. Conclusion:Endoscope-assisted lateral neck dissection is safe, feasible and with excellent cosmetic effect for the treatment of lymph node metastasis in the lateral cervical region of papillary thyroid carcinoma.

目的：对甲状腺乳头状癌（PTC）需行侧颈淋巴结清扫的患者进行前瞻性随机对照研究，以探讨腔镜辅助侧颈清扫的彻底性、安全性及美容性。 方法：选取因PTC行甲状腺全切、双侧中央区及单侧侧颈淋巴结清扫的患者36例，并将其随机分为腔镜辅助组（18例）和开放组（18例），比较2组临床特征、手术情况、术后并发症及美容满意程度。 结果：2组年龄、性别、肿瘤大小、清扫侧别、手术时间、术后住院时间、清扫淋巴结数量、转移淋巴结数量、术后声嘶及甲状旁腺功能减退方面比较差异均无统计学意义（P>0.05）；术后2组均无血肿、淋巴漏发生，术后6个月复查未见复发或残留，腔镜辅助组术后6个月血清Tg高于开放组，但差异无统计学意义（P>0.05）；腔镜辅助组术后3 d疼痛、术后1个月颈部麻木不适评分及术后3个月美容满意度评分均优于开放组（P<0.05）。 结论：腔镜辅助侧颈淋巴结清扫治疗PTC颈侧区淋巴结转移安全可行，美容效果极佳。.
