Comparison between Robotic Single-Port Myomectomy Using New da Vinci SP® Surgical System and Robotic Multi-Site Myomectomy

Abstract

<h3>Study Objective</h3> To compare the perioperative outcomes of the robotic single-port myomectomy (RSPM) using the new da Vinci SP® surgical system with those of the robotic multi-site myomectomy (RM) using the da Vinci Xi® surgical system. <h3>Design</h3> Multicenter retrospective case-controlled study. <h3>Setting</h3> A university tertiary care hospital. <h3>Patients or Participants</h3> A total of 101 patients were enrolled. 67 patients underwent RSPM and 34 patients underwent RM at November 2018 to May 2020 were included. <h3>Interventions</h3> All patients underwent robotic myomectomy who diagnosed uterine myoma with target size that the instrument could operate by entering the umbilicus. The choice of surgical modality was not influenced by the patient's history of previous abdominal surgery, body mass index, uterus size, location or type of myoma, or myoma size. <h3>Measurements and Main Results</h3> RSPM vs. RM patients demographics had no difference significantly in mean age, BMI, maximal diameter of myoma and total number of myomas. In terms of surgical outcomes, RSPM and RM has comparable in EBL (50 mL vs. 150 mL, p <0.05), Hemoglobin change (2.2±0.8 g/dl vs. 2.6±1.1 g/dl, p=0.046), operative time (105 min vs. 110 min, p = 0.001). Post-operative complication, conversion to laparotomy rate, tranfusion rate were similar between the two groups. <h3>Conclusion</h3> Robotic single-port myomectomy using new da Vinci SP® surgical system is feasible surgical modality as like as multi-site myomectomy. Further studies are needed to confirm these preliminary results and to determine the proper indications for the surgery.
