Abstract
Endoscopic thyroidectomy is popular among young patients because of its excellent cosmetic outcomes. But it takes a long time to become proficient and competent for surgeons. In addition, collaboration plays a critical role in endoscopic thyroidectomy. Our research aims to evaluate the learning curve of endoscopic thyroidectomy via breast areola approach, provide details of this approach, and demonstrate the importance of collaboration. The authors retrospectively analyzed 100 cases of benign and malignant thyroid disease who underwent endoscopic thyroidectomy via breast areola approach between January 2015 and December 2020, which were performed by the same group of surgeons with little experience of endoscopic thyroidectomy. The learning curve was analyzed by moving average method. The mean operation time, blood loss, tumor size, postoperative complications were used to determine learning curve progression. The learning curve in the first 30 cases were uplifted, stable at 30 to 60 cases and declined in the following cases. The mean operation time and blood loss decreased significant after the first 30 cases and again after the first 60 cases. And there was no difference in postoperative complications. A well-trained surgeon with experience in conventional open thyroidectomy can significantly reduce the total operation time by studying the learning curve. The key steps including establishment of working space and reaching for recurrent laryngeal nerve. A stable level can be achieved after 30 cases. More than 60 cases are required to become proficient. A successful endoscopic thyroid surgery requires a stable team.
