摘　　要：目的探讨无充气腋窝入路腔镜甲状腺系膜切除术的学习曲线。方法回顾性分析由同一手术团队2020年5月~2022年12月行无充气腋窝入路腔镜甲状腺系膜切除术44例资料。以手术时间为指标,应用累积和分析法研究该手术的学习曲线,将学习曲线的拐点作为学习提高期和成熟稳定期的分界线,比较2个阶段患者的一般资料、手术时间、术中出血量、住院时间、淋巴结清扫数目、术后并发症的差异。结果44例均顺利完成手术,无中转开放手术。学习曲线拐点在21例,以此为界分为学习提高期和成熟稳定期。两阶段一般资料无统计学意义(P>0.05);学习提高期的手术时间显著长于成熟稳定期[(124.5±9.9)min vs.(82.0±8.8)min,t=15.166,P=0.000],术后胸锁乳突肌肿胀僵硬发生率高,但差异无统计学意义[6例(28.6%)vs.1例(4.3%),χ^(2)=3.174,P=0.075];2个阶段术中出血量、住院时间、淋巴结清扫数目、术后其他并发症等方面差异无统计学意义(均P>0.05)。结论熟练掌握无充气腋窝入路腔镜甲状腺系膜切除术需要完成21例。Objective To explore the learning curve of endoscopic mesothyroid excision via gasless axillary approach.Methods Clinical data of 44 patients who underwent endoscopic mesothyroid excision via gasless axillary approach between May 2020 and December 2022 by the same surgical team were retrospectively analyzed.Taking operation time as index,the learning curve of the operation was studied with the cumulative sum method(CUSUM).The cut-off value of the learning curve was regarded as the dividing line of different stages.The general data,operation time,intraoperative blood loss,hospital stay,number of lymph node dissection,and postoperative complications were compared between the different phases of the learning curve.Results The operations were successfully completed in all the 44 patients without conversion to open surgery.The cumulative sum fitting curve reached the top at the 21 st case,which was used as the boundary to divide the learning curve into learning improvement stage and mature stable period.There was no statistically significant difference between the two stages in general data(P>0.05).The operation time in the learning improvement stage was significantly longer than in the mature stable period[(124.5±9.9)min vs.(82.0±8.8)min,t=15.166,P=0.000].The incidence of postoperative sternocleidomastoid muscle swelling and stiffness in patients in the learning improvement stage was higher than that in the mature stable period,but the difference was not statistically significant[6 cases(28.6%)vs.1 case(4.3%),χ^(2)=3.174,P=0.075].There was no significant difference between the two groups in terms of intraoperative bleeding,hospital stay,number of lymph node dissection,and other postoperative complications(all P>0.05).Conclusion To proficiently master the endoscopic mesothyroid excision via the gasless axillary approach,21 cases need to be completed.
