Comparison of learning curves for laparoendoscopic single-site myomectomy performed by 2 surgeons

We aimed to compare the learning curves of 2 surgeons with different endoscopic bases when performing laparoendoscopic single-site myomectomy (LESS-M). We retrospectively analyzed and compared 2 groups of patients who underwent LESS-M performed by 2 surgeons with different bases in multi-port laparoscopic surgery (MLS) from October 2019 to December 2020 at West China Second Hospital of Sichuan University. Patients' characteristics and related surgical indicators were compared, and surgeons' learning curves were analyzed using a cumulative sum analysis. All of the patients completed LESS-M without converting to MLS or laparotomy, despite Surgeon A being MLS-unqualified and Surgeon B being MLS-qualified. There were no significant differences in patients' characteristics or surgical indicators between the 2 groups (P > 0.05 for all). Surgeons A and B crossed the learning curve after 21 and 18 cases, respectively. LESS-M is safe and feasible. Approximately 20 cases are required for surgeons to achieve LESS-M proficiency, and surgeons without MLS experience can still master LESS-M.
