intramural type measured about 26 £ 23cm2 which is successfully performed the SCH with BS using the da Vinci SP system. Total operative time was 145 minutes and the estimated blood loss was 250 mL. The hospital stay was 2.5 days. No operative or postoperative complications occurred. To the best of our knowledge, this is the largest leiomyoma case of robotic-assisted single port SCH using the da Vinci SP system and we Ò have known the advantage of the da Vinci SP surgical system on the huge intraabdominal mass requiring procedures above the umbilicus level as in this case. Conclusion: The da Vinci SP surgical system enables easy rotation of camera and instruments at once and this make it easy to perform the procedures which are performed above the umbilicus for the huge uterine leiomyoma reaching the diaphragm.
1:20 PM: STATION G 2175 Use of a Mathematical Model for the Prediction of Surgical Time in Robotic Myomectomy Cortes AL,1 Cortes Vazquez A,1,* Gallardo Valencia LE,Sr.1 Gongora Rodriguez A,2 Guzman M3. 1Laparoscopic and Robotic Surgery, Centro M edico Nacional 20 de Noviembre, Mexico City, DF, Mexico; 2 Reproductive Endocrinology, Centro M edico Nacional 20 de Noviembre, Mexico City, DF, Mexico; 3Laparoscopic and Robotic Surgery, Centro M edico Nacional 20 de Noviembre, Mexico City, EM, Mexico *Corresponding author. Study Objective: To evaluate the factors associated with console time during robotic myomectomy. And to incorporate them in a mathematical formula that could predict the surgical time. Design: Prospective and descriptive study. Setting: Centro Medico Nacional 20 de Noviembre. Patients or Participants: All patients who underwent robotic myomectomy. Interventions: All the demographic and surgical information from patients who underwent a robotic myomectomy were collected before and during the procedure. The data collected were age, body mass index, number of myomas, size of the biggest myoma, parity, surgical bleeding, Docking time, console time and surgical time. Using the factors that correlated the most with the console time. A multiple linear regression model was made and a mathematical formula was developed for the prediction of console time. Measurements and Main Results: In robotic myomectomy the only factor that correlates the most with surgical time is the fibroids size. We observed that there is a direct relationship between surgical time and fibroids size. Therefore console time can be predicted as: Surgical time= 84.316 + 13.089 (fibroids size). Conclusion: Surgical time can be predicted with the aforementioned formula. We believe that the utilization of a mathematical model can be used to increase the efficiency in operating rooms.

Virtual Poster Session 4: Robotics (1:20 PM — 1:30 PM) 1:20 PM: STATION I 1885 Robotic-Assisted Hysterectomy and Bilateral Salpingo-Oophorectomy with Uterine Artery Ligation in a Case of Tubo-Ovarian Abscess with Severe Pelvic Adhesion Fang JJ,1,* Liu WM2. 1Taipei Medical University Hospital, Taipei, Taiwan; 2Obstetrics and Gynecology, Taipei Medical University Hospital, Taipei, Taiwan *Corresponding author. Video Objective: Surgeries for tubo-ovarian abscess (TOA) may be very challenging due to severe adhesions from the abscess to the surrounding inflamed tissue. Treatment was often limited to drainage of the abscess due to the difficulty of more extensive surgery. This video demonstrates successful robotic-assisted total hysterectomy with bilateral salpingooophorectomy and uterine artery ligation with adhesiolysis for treatment of a case with tubo-ovarian abscess. Techniques of visualizing surgical anatomy and localizing the uterine artery will also be demonstrated. Setting: A 41 year-old G3P2SA1 female patient presented to our outpatient clinic with lower abdominal pain with fever for 1 month. She had undergone cesarean delivery twice 17 and 18 years ago with no other significant gynecologic history. On pelvic examination, lifting tenderness with moderate odorous discharge was noted. Transvaginal ultrasound showed bialteral adnexal mass, measuring 5 £ 2 cm and 5 £ 3 cm. She was then admitted to our department under the tentative diagnosis of tuboovarian abscess. Interventions: Robotic-assisted total hysterectomy with bilateral salpingo-oophorectomy, uterine artery ligation and adhesiolysis was performed on the second day of hospitalization. Conclusion: Total hysterectomy with bilateral salpingo-oophorectomy may be feasible in the treatment of tubo-ovarian abscess by using roboticassisted instruments. Due to the greater precision, better visualization, and higher dexterity of robotic-assisted surgeries.

Study Objective: To evaluate the concurrent interaction of laparoscopic and robotic-assisted surgery in the initial learning period of endometrial cancer staging. Design: Retrospective cohort study.
Abstracts / Journal of Minimally Invasive Gynecology 26 (2019) S98−S231 Setting: A tertiary care referral hospital. Patients or Participants: The first 44 consecutive patients with endometrial cancer underwent laparoscopic (LSS) or robotic-assisted staging surgery (RSS) from February 2012 to October 2015. Interventions: Quality of surgery was determined by the number of lymph nodes dissected and learning curve was estimated by operative time with respect to chronologic order of operation. Measurements and Main Results: Twenty-four patients received LSS and 20 patients received RSS. RSS required longer operative time, but obtained more total number of lymph nodes compared with LSS (286.9 vs. 201.9 min (p < 0.001); 26.2 vs.20.7 (p < 0.05), respectively. There were no difference in blood loss, number of para-aortic nodes removed, complications and hospital stay between the two types of surgery. An additive model based on tumor grade, body mass index, estimated blood loss and chronological order of operation was constructed to fit operative time of these two types of surgery. Proficiency of achievement was not observed for LSS and was 6 for RSS. Conclusion: Operative time was longer but Lymph node dissection was easier in RSS. Learning curve for LSS to maintain similar surgical quality as RSS was not observed. The concurrent use of robotic platform in the initial practice of minimally invasive staging surgery could optimize surgical technique for LSS.

Video Objective: To describe and demonstrate the feasibility and safety of robotic laparoendoscopic single-site radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. Setting: A university hospital. Interventions: Robotic laparoendoscopic single-site radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. All of the interventions were performed using a da Vinci Si surgical system and all the surgery instrument was conventional robotic instruments. A uterine manipulator and an indwelling catheter (Foley catheter) were used. The patient was in the Trendelenburg position, and the robot was placed between her legs. By adopting the principle of the chopstick technique for R-LESS, a 30˚ robotic lens was placed in the upward configuration to reduce collision and achieve a better view. Conclusion: Our preliminary experience has demonstrated that with experienced laparoscopic skills, R-LESS with the da Vinci Si system is a feasible and safe surgical approach for performance of radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. Further studies with greater number of patients in multiple settings will help us to fully elucidate the role of da Vinci Si surgical system in single-site gynecologic surgery.

S219 Manhasset, NY; 3OBGYN/MFM, Northwell, Manhasset, NY; 4Minimally Invasive Gynecologic Surgery, North Shore University Hospital, Manhasset, NY *Corresponding author. Study Objective: Using a patient’s obstetrical history, symptomatology, and radiologic findings of cesarean scar defects (CSD) to establish criteria to triage patients who require surgical repair. Additionally, to outline surgical technique for successful Robotic-assisted laparoscopic repair of CSDs. Design: Comprehensive overview of diagnosis, radiological findings and repair of CSD. Setting: Two large tertiary care academic medical centers. Patients or Participants: Patients with previous cesarean section who are referred for possible surgical intervention for CSD. Interventions: Robotic-assisted laparoscopic approach after proper multidisciplinary planning with Radiologist, Maternal fetal medicine specialist, and minimally-invasive gynecologic surgeon. Measurements and Main Results: Cesarean scar defects are readily visible on ultrasound evaluation, and is a finding in many patients following cesarean section. Currently, there are no accepted guidelines to aid in the decision for when surgical management is required. The study will combine obstetrical history, symptomatology, and, most importantly, radiologic findings to aid clinicians in designing a treatment plan. Radiologic findings include degree of myometrial thinning and presence/width of the serosal dehiscence. If surgical intervention is necessary, outline the steps to robotic assisted laparoscopic repair of CSD. Included in this analysis are radiographic images of defects and video of surgical repairs. Conclusion: There are numerous reports of the minimally invasive repair of CSD; however, it remains unknown in the obstetrical literature when interventions are required. Patients with minimal myometrial thinning and without evidence of serosal dehiscence may not require repair of the defect. More evidence is needed to observe obstetrical outcomes with or without repair.
