Initial experience and surgical outcomes of robotic‐assisted total hysterectomy using the da Vinci SP surgical system

Abstract

IntroductionThe da Vinci SP surgical system is a surgical platform capable of implementing robotic‐assisted surgery through a single port and was first introduced in Japan at our hospital. In this paper, we describe our experience of the initial introduction of the da Vinci SP surgical system and its surgical outcomes. This is the first report on the surgical outcomes of using da Vinci SP, and its comparison with the conventional system in Japan.MethodsAfter developing an application for a highly difficult new medical technology in‐house, we compared the surgical outcomes (median values) of 15 patients who had undergone total hysterectomy at our hospital using the da Vinci SP (1‐port) system (SP group) for uterine myoma after March 2023 and of 154 patients who underwent total hysterectomy using the conventional da Vinci Xi (four ports) system (Xi group) for uteri weighing <500 g.ResultsThe results of the comparison of the characteristics between 15 patients in the SP group and 154 patients in the Xi group were as follows: uterus weight (g): 230 (90–500) versus 222 (55–496) (p = .35); surgical time (minutes): 199 (171–251) versus 198 (88–387) (p = .63); intraoperative blood loss (mL): 13 (5–82) versus 20 (2–384) (p = .17); and rate of surgical complication (%): 0.0 versus 1.3 (p = .66). The data indicated a comparable weight of the resected uterus, surgical time, intraoperative blood loss, and rate of surgical complications between the two groups.ConclusionRobotic‐assisted total hysterectomy using the da Vinci SP surgical system allowed clinicians to safely perform surgeries according to the conventional systems.

Surgical Outcomes of da Vinci Xi™ and da Vinci SP™ for Early-Stage Endometrial Cancer in Patients Undergoing Hysterectomy

“…Seon et al reported that although da Vinci SP™ had a longer console and total operation time than da Vinci Xi™, robotic endometrial cancer surgical staging using da Vinci SP™ appears to be safe and feasible in terms of intra-and post-operative complications [16]. Miyamura et al investigated the initial results of da Vinci SP™ in benign gynecological diseases, and reported that robotic-assisted total hysterectomy using the da Vinci SP™ allowed clinicians to safely perform surgeries according to the conventional systems [17].…”
