2835 Robot-Assisted Laparoendoscopic Single-Site (Ra-Less) Myomectomy Using Lapsingle Port

Abstract

Study Objective To report our experience with robot-assisted laparoendoscopic single-site (RA-LESS) myomectomy using Lapsingle access, including outcomes & feasibility of this procedure. Design A Retrospective cohort study, from April 2018 to March 2019. Setting Single surgeon, Single medical center, University hospital. Patients or Participants Twenty-five patients with symptomatic subserosal or intramural myomas Interventions RA-LESS myomectomy was performed with the da Vinci Xi Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA, USA) employing 8 mm endoscope and single-site 5 mm instrumentation through a laparoendoscopic single-site (LESS) port (Lapsingle, Sejong Medical, KOREA). Measurements and Main Results The mean age (±SD) and mean BMI were 40.2 ± 7.2 years and and 22.5 ± 2.7 kg/m2. Mean diameter of the largest tumor was 6.8 ± 1.5 cm (median 6.1 cm, range 3.1-9.7 cm), while mean number of tumors removed was 2.2 ± 1.8, ranging from 1 to 5 per surgery. The mean operating time, hemoglobin change, return of bowel activity, and length of hospital stay were 95.2±43.2 min, 1.5±0.7 g/dL, 36.8±9.1 h, and 3.8±0.7 days, respectively. All procedures were successfully performed without conversion to conventional LESS surgery, multi-port laparoscopy or laparotomy. There were no surgical or wound complications in any patient, and the histopathological result was leiomyoma in all the cases Conclusion RA-LESS myomectomy is a safe and feasible surgery with excellent cosmetic and postoperative outcomes in selected patients. Further investigation is needed to define the patient groups that will most benefit from it.
