目的总结Millikan无张力疝修补术治疗腹股沟疝的经验。方法对笔者2008年1月至2010年1月期间完成的Millikan无张力疝修补术患者的临床资料进行总结、分析。结果本组 32例共35侧疝，按国内疝学组分型(2003年)，Ⅰ型2侧，Ⅱ型9侧，Ⅲ型21侧，Ⅳ型3侧。直疝6侧，斜疝29侧。其中行急诊疝修补术2例。术后发生尿潴留2例(6.25%),无切口感染、血肿、睾丸炎等并发症发生； 住院时间3~5 d，平均3.5 d。随访2~24个月，平均18个月，无复发及慢性疼痛者。结论Millikan手术是一种操作简便、安全、符合无张力疝修补原理的术式，适用于Ⅱ~Ⅳ型腹股沟疝的修补。
ObjectiveTo explore the learning curve of endoscopic thyroidectomy using the gasless unilateral axillary approach for papillary thyroid microcarcinoma.MethodsWe retrospectively analyzed the clinical data of 51 patients diagnosed with papillary thyroid microcarcinoma who underwent an endoscopic thyroidectomy using a gasless unilateral axillary approach by the same surgeon from November 2019 to September 2020 in the Department of Thyroid and Parathyroid Surgery, West China Hospital, Sichuan University. The cumulative sum (CUSUM) analysis was used to determine the learning curve of the technology, and the CUSUM learning curve was modeled by the best fit. The operative time, intraoperative blood loss, number of lymph nodes dissected, incidence of complications and postoperative hospital stay in different phases of the learning curve were compared.ResultsThe CUSUM fitting curve reached the top at the 18th case. As a cut-off point, the learning curve was divided into two stages: the learning improvement period and the proficiency period. The operative time of patients in the proficiency stage was significantly shorter than that in the learning improvement stage (P<0.05), and there were no statistically significant differences in other data of patients in the two stages (P>0.05).ConclusionThe CUSUM analysis method is used to accurately analyze the learning curve of endoscopic thyroidectomy using the gasless unilateral axillary approach for papillary thyroid microcarcinoma, indicating that the cumulative number of operations required to master this technique is 18 cases.
