[Comparison of clinical effects of endoscopic thyroidectomy using the modified gasless transsubclavian approach and traditional open surgery for cN0 unilateral papillary thyroid carcinoma].

Objective: To compare the clinical effects of endoscopic thyroidectomy using a modified gasless transsubclavian approach and the traditional neck approach for unilateral papillary thyroid carcinoma (cN0). Methods: The clinical data of 135 patients with cN0 papillary thyroid carcinoma who underwent unilateral thyroidectomy in the Department of Thyroid Surgery, the First Hospital of Jilin University from October 2020 to November 2022 were retrospectively analyzed. There were 37 males and 98 females, aging (43.2±8.8) years (range: 21 to 59 years). There were 51 cases using the modified gasless transsubclavian approach (TS group) and 84 cases using the traditional neck approach (TN group). Comparative analyses were performed between the operative results of the 2 groups by t-test, Wilcoxon rank sum test, and χ2 test. Results: All endoscopic operations were successfully completed without conversion to the traditional neck approach. Compared to the TN group, the TS group had a longer operation time (M(IQR)) (73.5 (22.5) minutes vs. 90.0 (30.0) minutes, Z=-5.831, P<0.01), more postoperative drainage (60 (25) ml vs. 95 (45) ml, Z=-6.275, P<0.01), higher hospitalization costs (22 687 (3 488) yuan vs. 26 652 (2 431) yuan, Z=-6.944, P<0.01), and a higher rate of parathyroid autotransplantation (15.5% (13/84) vs. 60.8% (31/51), χ2=29.651, P<0.01). There was no significant difference in the total exposure rate of the central compartment, postoperative hospitalization time, the number of dissected lymph nodes, the number of metastatic lymph nodes, C-reactive protein ratio before and after operation, and preoperative and postoperative parathyroid hormone (all P>0.05). Conclusion: Endoscopic thyroidectomy using the modified gasless transsubclavian approach is safe for cN0 papillary thyroid carcinoma, with longer operating time, more postoperative drainage, higher hospitalization costs, and more difficulty in preserving the inferior parathyroid gland in situ compared to traditional open surgery.目的： 比较改良免充气经锁骨下入路腔镜手术与传统开放手术治疗cN0期单侧甲状腺乳头状癌的临床效果。 方法： 回顾性分析2020年10月至2022年11月于吉林大学第一医院普通外科中心甲状腺外科接受单侧甲状腺癌根治术的135例cN0期单侧甲状腺乳头状癌患者的资料。男性37例，女性98例，年龄（43.2±8.8）岁（范围：21~59岁）。51例接受改良免充气经锁骨下入路腔镜手术（腔镜组），84例接受传统颈部切口手术（开放组）。采用t检验、Wilcoxon秩和检验和χ2检验比较两组手术结果。 结果： 所有经锁骨下入路腔镜甲状腺手术均顺利完成，无中转开放手术。与开放组相比，腔镜组手术时间［M（IQR）］稍长［73.5（22.5）min比90.0（30.0）min，Z=-5.831，P<0.01］，引流量更多［60（25）ml比95（45）ml，Z=-6.275，P<0.01］，住院费用更高［22 687（3 488）元比26 652（2 431）元，Z=-6.944，P<0.01］，甲状旁腺自体移植率更高［15.5%（13/84）比60.8%（31/51），χ2=29.651，P<0.01］。两组的中央区完全显露率、术后住院时间、清扫淋巴结数目、转移淋巴结数目、手术前后C反应蛋白比值及手术前后甲状旁腺素等差异均无统计学意义（P值均>0.05）。 结论： 改良免充气经锁骨下入路腔镜手术的创伤和安全性与开放手术相当，手术时间稍长，引流量略多，住院费用略高，下位甲状旁腺原位保留难度增加。.
