摘要目的:探讨经双侧腋窝乳晕入路（bilateral axillo-breast approach, BABA）机器人甲状腺手术行双侧颈侧区淋巴结清扫（lymph node dissection, LND）的安全性和有效性。方法:回顾性分析解放军联勤保障部队第九六〇医院（原济南军区总医院）甲状腺乳腺外科2014年1月至2023年1月收治的37例甲状腺癌伴双侧颈侧区淋巴结转移（lymph node metastasis, LNM）患者，行经BABA机器人下甲状腺全切+双侧中央区+双侧颈侧区LND的临床资料。女24例，男13例，年龄（33.22±10.53）岁。记录肿瘤直径、中央区和侧区LND个数及转移个数、手术时长、住院天数、并发症、术后美容效果评分等，应用SPSS 25.0软件行统计分析，计量资料用均数±标准差（ ± s）表示，计数资料用百分比和数字表示。 结果:37例均顺利完成经BABA机器人下甲状腺全切+双侧中央区+双侧颈侧区LND。病理类型均为甲状腺乳头状癌（papillary thyroid carcinoma ,PTC），肿瘤最大径为（1.47±0.85）cm，中央区LND数目为（19.46±8.84）枚，转移数目为（10.24±5.95）枚；双侧颈侧区LND数目为（38.92±14.21）枚，转移为（7.92±5.84）枚。手术时长为（288.05±77.09）min，住院时间为（10.76±3.92）d，术后住院时间为（8.03±2.08）d。37例均未发生永久性甲状旁腺功能减退（hypoparathyroidism，HPT）和永久性喉返神经损伤，且未发生感染、副神经及膈神经损伤。15例术后出现暂时性HPT，1例发生暂时性喉返神经损伤，2例发生乳糜漏。术后1个月美容评分为（9.51±0.69）分。术后随访时间为（27.81±15.10）个月，2例分别于术后10个月、15个月发生颈部淋巴结复发，均再次行经BABA颈部LND，经术后随访，患者均无复发征象。结论:对严格挑选的甲状腺癌伴双侧颈侧区LNM的患者行经BABA机器人下双侧颈侧区LND是安全可行，并可取得良好美容效果。

abstractsObjective:To research the efficacy and safety of robotic thyroidectomy and bilateral modified radical neck dissection through bilateral axillo-breast approach (BABA) .Methods:We retrospectively analyzed the clinical data of 37 patients with thyroid cancer who received bilateral modified radical neck dissection through the BABA at the Department of Thyroid and Breast Surgery of the 960th Hospital of the People’s Liberation Army from Jan. 2014 to Jan. 2023. There were 24 females and 13 males, and the average age of the patients was (33,22±10.53) years old. The tumor diameter, number of lymph node dissection and metastasis in the central and lateral regions, average operation time, average hospital stay, complications, and aesthetic score were recorded. SPSS 25.0 software was used for statistical analysis, and the measurement data was calculated using mean ± standard deviation ( ± s), and the counting data was expressed in percentages and numbers. Results:A total of 37 thyroid cancer patients underwent robotic bilateral regional lymph node dissection. The 37 patients received total thyroidectomy, bilateral central compartment and cervical lateral regional lymph node dissection. All the pathological types were papillary carcinoma, with a maximal tumor diameter of (1.47±0.85) cm. The average number of central lymph nodes dissected was 19.46±8.84, and there were (10.24±5.95) metastases; The average number of lymph nodes removed from the bilateral cervical region was 38.92±14.21, and there were (7.92±5.84) metastases. The average operation time was (288.05±77.09) min, the average length of stay in the hospital was (10.76±3.92) days, and the average length of stay in the hospital following surgery was (8.03±2.08) days. These patients had no permanent hypoparathyroidism, permanent recurrent laryngeal nerve palsy, infection, accessory nerve injury and phrenic nerve injury after operation. Transient hypoparathyroidism occurred in 15 patients, transient recurrent laryngeal nerve palsy occurred in 1 patient, and chyle leak occurred in 2 patients. One month after surgery, the aesthetic score was 9.51±0.69.Two patients were found lymph node metastases during the (27.81±15.10) months of follow-up, and received robotic cervical lymph node dissection with BABA.Conclusion:For carefully chosen thyroid cancer patients with bilateral lateral cervical region lymph node metastases, robotic bilateral cervical lymph node regional dissection via BABA is safe and feasible, and good cosmetic results can be obtained.
