PurposeTo report preliminary experience of single-port robotic surgery using the da Vinci SP surgical system in gynecologic tumors.Materials And MethodsThis was a retrospective study on 100 consecutive patients who underwent da Vinci SP single-port robotic surgery between November 2018 and January 2021. All procedures were performed by an experienced gynecologic surgeon using a single 2.5-cm umbilical incision.ResultsOf the 100 cases, the procedures included myomectomy (n=76), hysterectomy (n=2), endometrial cancer surgical staging (n=14), radical hysterectomy (n=3), radical trachelectomy (n=3), and ovarian cystectomy (n=2). None of the cases was converted to robotic multiport or open surgery. The median docking time was 5.0 minutes [interquartile range (IQR), 3.0-7.0], the median console time was 107.5 minutes (IQR, 78.7-155.8), and the median total operation time was 250.0 minutes (IQR, 215.0-310.0). The median estimated blood loss was 50.0 mL (IQR, 30.0-100.0), and the median change in hemoglobin level was 0.8 g/dL (IQR, 0.3-1.3). The median pain scores rated on a numerical rating scale immediately after and at 6, 12, and 24 hours after surgery were 5, 2, 2, and 2, respectively. The mean duration of postoperative hospitalization was 2.8 days.ConclusionDa Vinci SP single-port robotic surgery was successfully performed in various gynecologic tumors without significant complications. Therefore, this surgical system could be applied in patients who want precise gynecologic surgery while minimizing surgical incision.© Copyright: Yonsei University College of Medicine 2022.
