Abstract

Aim: The purpose of this study was to report on 626 cases of successful robotic single-site (RSS) surgeries to address various types of gynecologic disease and to evaluate the outcomes and learning curve inherent to RSS surgery in the gynecology field. Methods: A total of 626 cases of RSS surgeries were performed by 3 gynecologic surgeons at Ewha Womans University Medical Center, Robot Surgery Center from November 2014 to January 2018 were collected retrospectively. All of the patients' charts were reviewed, and the clinical characteristics and surgical variables were analyzed. Results: Among the total of 626 cases, there were 220 cases of RSS myomectomy (RSSM), 182 cases of RSS hysterectomy (RSSH), 195 of RSS adnexectomy, 24 of RSS sacrocolpopexy (RSS SCP) and 5 were classified as other RSS surgeries. The patient's mean age was 38.98 ± 10.07 years. There was 3.99 ± 2.15 min of mean docking time and 117.78 ± 51.18 min of mean operating time. The surgical variables were analyzed annually. The total operating time was seen to decrease significantly according to each period. The docking time declined significantly and gradually after 1 year. We also analyzed each of the surgical types by time. The operating time of RSSH, RSSM, RSS adnexectomy and RSS SCP fell over time. The tendency found was for operating time to decline sharply following the first 10 cases. When we analyzed the data at annual intervals, the operating time was most significantly less and stable following the first year. There were a few intraoperative or perioperative complications in 16 cases (2.6%). Conclusion: Robotic single-site surgery is a feasible and safe procedure for treating various kinds of gynecologic diseases. The learning curve was approximately 10 cases of RSS surgery in gynecologic disease, having a greater amount of experience at performing RSS surgery was revealed to be key to achieving better surgical outcomes.
