摘要目的:探讨利用机器人手术系统行双侧腋窝乳晕入路甲状腺手术的安全性和有效性。方法:回顾性分析联勤保障部队第九六〇医院甲乳外科2014年2月至2019年5月连续1 000例应用机器人手术系统行双侧腋窝乳晕入路甲状腺手术患者的临床资料。男性216例，女性784例，年龄（42.3±11.5）岁（范围：7~75岁）。甲状腺良性肿瘤270例；恶性肿瘤730例，肿瘤最大径（7.9±6.7）mm（范围：0.1~60.0 mm）。结果:999例患者成功完成机器人甲状腺手术，1例中转开放手术。术后住院时间（7.5±2.5）d（范围：2~30 d）。730例甲状腺癌患者中，乳头状癌725例，微小乳头状癌占79.3%（579/730）。清扫中央区淋巴结（11.2±6.1）枚（范围：1~44枚），清扫颈侧区淋巴结（14.0±8.8）枚（范围：1~52枚），颈部淋巴结阳性比例50.8%（371/730）。术后暂时性甲状旁腺功能减退和喉返神经损伤发生率分别为24.70%（247/1 000）和5.60%（56/1 000），术后永久性甲状旁腺功能减退和喉返神经损伤发生率均为0.20%（20/1 000）。随访（35.4±15.2）个月（范围：10.4~76.2个月），4例患者发生局部淋巴结复发。所有患者均对术后美容效果满意。结论:对于甲状腺良性肿瘤、合并中央区或颈侧区淋巴结转移的早期甲状腺癌患者，利用机器人手术系统行经双侧腋窝乳晕入路甲状腺手术安全有效，具有理想的美容效果。

abstractsObjective:To examine the surgical outcome, completeness and safety of robotic thyroidectomy by bilateral axillo-breast approach (BABA).Methods:From February 2014 to May 2019, 1 000 cases of robotic thyroidectomy via BABA at the Department of Thyroid and Breast Surgery, the 960 th Hospital of People′s Liberation Army were performed. The clinicopathologic characteristics, operation times, perioperative complications, and oncologic outcomes of patients underwent robotic thyroidectomy were collected and reviewed retrospectively. There were 216 males and 784 females, aging (42.3±11.5) years (range: 7 to 75 years). There were 270 cases with benign tumors, and 730 cases with malignant cancers (the tumor diameter was (7.9±6.7) mm (range: 0.1 to 60.0 mm)). Results:There were 999 patients received robotic thyroidectomy using BABA approach successfully, while only 1 case conversed to open operation. The postoperative hospital stay was (7.5±2.5) days (range: 2 to 30 days). Among the 730 patients with thyroid cancers, 725 cases (99.3%) were papillary thyroid carcinoma, 579(79.3%) cases were with papillary thyroid microcarcinoma. Lymph node metastasis was observed in 371(50.8%) cases. The retrieved central lymph node number was 11.2±6.1 (range: 1 to 44),and the retrieved lateral lymph node number was 14.0±8.8 (range: 1 to 52). Postoperative transient hypoparathyroidism and vocal cord palsy occurred in 247(24.70%) and 56(5.60%) cases. Both of permanent hypoparathyroidism and vocal cord palsy occurred in 2 (0.20%) cases. Other surgical complications included chyle leakage (6.1%, 28/460), trachea injury (0.40%, 4/1 000), carotid artery injury (0.10%, 1/1 000). Local regional lymph node recurrence was developed in 4 patients. All patients were satisfied with the postoperative cosmetic outcomes.Conclusions:Robotic thyroidectomy by BABA is safe and effective, suitable for large benign tumors and early thyroid cancers with central or lateral lymph node metastasis. It could obtain superior cosmetic results.
