Robotic single-site staging operation for early-stage endometrial cancer: initial experience at a single institution.

Objective: The aims of this study were to introduce surgical guidelines, and to evaluate the feasibility and safety of a robotic single-site staging (RSSS) operation for early-stage endometrial cancer.

Methods: Patients with a preoperative diagnosis of endometrial cancer (International Federation of Gynecology and Obstetrics stages IA to IB) from endometrial curettage and preoperative imaging studies were selected at Dongsan Medical Center from March 2014 to November 2015. All surgical procedures, including hysterectomy, salpingo-oophorectomy, bilateral pelvic node dissection, and cytology aspiration, were performed by robotic single-site instruments (da Vinci Si surgical system; Intuitive Surgical, Sunnyvale, CA, USA).
