Objective To explore the learning curve of endoscopic thyroidectomy using the gasless unilateral axillary approach for papillary thyroid microcarcinoma.Methods We 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.Results The 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).Conclusion The 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.
