Background: The objective was to evaluate the learning curve for performing a robotic hysterectomy to treat benign gynaecological disease. Methods: Thirty-six patients underwent robotic hysterectomy for benign indications. A systematic chart review of consecutive cases was conducted. The collected data included age BMI operating time set-up time docking time uterine weight blood loss intraoperative complications postoperative complications conversions to laparotomy and length of hospital stay. Results: The mean operating set-up and docking times were 169±54.5 52.9±12.4 and 7.8±7.6min respectively. The learning curve analysis revealed a decrease in both docking and operating times with both curves plateauing after case 9. Conclusions: The learning curve analysis revealed a decrease in docking time and operating time after case 9 suggesting that there might be a fast learning curve for experienced laparoscopic surgeons to master robotic hysterectomy and that the docking process does not have a significant negative influence on the overall operating time. © 2022 Elsevier B.V.

Learning Curve Analysis of Intracorporeal Cuff Suturing During Robotic Single-Site Total Hysterectomy
(ELSEVIER SCIENCE INC, 2015) Ali Akdemir; Burak Zeybek; Banu Ozgurel; Mehmet Kemal Oztekin; Fatih Sendag; Akdemir, Ali; Ozgurel, Banu; Zeybek, Burak; Oztekin, Mehmet Kemal; Sendag, Fatih
Study Objective: To analyze the learning curve of intracorporeal cuff suturing during robotic single-site total hysterectomy. Design: Retrospective study (Canadian Task Force classification Setting: University hospital. Patients: Twenty-four patients with benign indications for hysterectomy. Interventions: Twenty-four patients who underwent robotic single-site total hysterectomy to treat benign indications were included in the study. Surgical procedures were performed by a single surgeon with extensive experience in laparoscopy using the single-site platform of the da Vinci Surgical System. All vaginal cuffs were closed intracorporeally using semi-rigid single-site instruments. Measurements and Main Results: An exponential learning curve technique was used to analyze the learning curve. The overall mean (SD) vaginal cuff closure time was 23.2 (7) minutes. Learning curve analysis revealed a decrease in vaginal closure time after 14 procedures. Conclusions: An experienced robotic surgeon requires approximately 14 procedures to achieve proficiency in intracorporeal cuff suturing during robotic single-site total hysterectomy. Novel instruments that create perfect triangulation are needed to overcome the current challenges of suturing and to shorten operative time. (C) 2015 AAGL. All rights reserved.

Which Should Be the Preferred Technique during Laparoscopic Ovarian Cystectomy: Hemostatic Sutures or Bipolar Electrocoagulation? A Randomized Controlled Prospective Study of Long-Term Ovarian Reserve
(SAGE Publications Inc. claims@sagepub.com, 2017) Cagdas Sahin; Ali Osman Akdemir; Ahmet Mete Ergenoǧlu; Banu Ozgurel; Ahmet Özgür Yeniel; Dilek Taşkiran; Fatih Şendaǧ; Ergenoglu, Ahmet Mete; Sahin, Cagdas; Akdemir, Ali; Yeniel, Ahmet Ozgur; Ozgurel, Banu; Taskiran, Dilek; Sendag, Fatih
The aim of the present study was to determine the long-term effects of different laparoscopic hemostatic techniques on ovarian reserve after ovarian cystectomy. Ninety patients with unilateral ovarian cysts were recruited and randomly distributed into 2 groups. Laparoscopic stripping cystectomy was performed in all patients. Afterward cystectomy hemostasis was achieved via hemostatic suture or bipolar electrocoagulation. Serum levels of anti-Müllerian hormone (AMH) were determined preoperatively and postoperatively at 1 3 and 12 months and patients were evaluated for residual ovarian volume antral follicle count and pregnancy. The statistical difference was determined between the 2 groups in terms of AMH levels at 3 months (hemostatic suture group = 3.17 ± 3.40 vs bipolar electrocoagulation group = 2.38 ± 2.57 P =.006) and 12 months (hemostatic suture group = 3.71 ± 3.09 vs bipolar electrocoagulation group = 2.78 ± 2.85 P =.005). In addition in the hemostatic suture group there was no statistically significant difference between preoperative and postoperative AMH levels (P =.165) and between the postoperative antral follicle count (P =.779) and the residual ovarian volume (P =.248) whereas in the bipolar electrocoagulation group postoperative AMH levels were lower than preoperative levels (P =.028) and postoperative residual ovarian volumes at 3 and 12 months were lower than those at 1 month (P =.001). Nonetheless pregnancy rates were not significantly different (P =.546). Bipolar electrocoagulation is more destructive compared with hemostatic suture. However the ovarian reserve does not decrease further during the follow-up period. © 2017 Elsevier B.V. All rights reserved.
