Comparison of Long-Term Outcomes in Early-Stage Endometrial Cancer: Robotic Single-Site vs. Multiport Laparoscopic Surgery

Abstract

The purpose of this study was to establish the noninferiority of robotic single-site (RSS) surgery compared with multiport laparoscopic (MPL) surgery in surgical outcomes and overall survival for early endometrial cancer. This study was conducted retrospectively in a single center and included 421 patients who underwent either RSS (n = 146) or MPL (n = 275) surgery between 2014 and 2022. In terms of perioperative outcomes, the RSS group had a longer operating time than the MPL surgery group (mean (standard deviation [SD]) RSS 97.55 [29.79] vs. MPL 85.56 [26.13], p p = 0.196 and p = 0.080, respectively). The patients in the RSS group were discharged earlier than those in the MPL group (mean [SD]): 4.06 [3.24] vs. 9.39 [4.76], p p = 0.27) and overall survival rates (p = 0.5) either. In conclusion, this study suggests that RSS and MPL surgery are both safe and effective options for staging operations in patients with early-stage endometrial cancer.
