Current strategies for fertility preservation rely heavily on assisted reproductive technology and fertility-sparing surgery. Whether seeking to avert loss of fertility associated with excision of adnexal or uterine disease or to preempt gonadal failure resulting from chemotherapy or radiation, each woman is unique in her reproductive endeavor and will benefit from careful consideration of her fertility goals together with a specialist in assisted reproductive technology and reproductive surgery. Because avoidance of laparotomy reduces tissue trauma and adhesion formation, advanced laparoscopic surgery is an indispensable tool for all specialists who provide care for women seeking fertility preservation. Computer-assisted laparoscopy, commonly known as robotic surgery, addresses the practical limitations of conventional laparoscopic surgery and holds the promise of making complex fertility-sparing procedures safe and reproducible in the hands of reproductive specialists. Herein we illustrate the transforming capabilities of robotics in reproductive surgery and highlight the current and future potential of this technology in fertility preservation.

Purpose: Robotic surgical technology has been adopted by surgeons with and without previous standard laparoscopic experience. The necessity or benefit of prior training and experience in laparoscopic surgery is unknown. We hypothesized that laparoscopic training enhances performance in robotic surgery. Materials and Methods: Fourteen medical students with no surgical experience were instructed to incise a spiral using the da Vinci® surgical robot with time to completion and errors recorded. Each student was then trained for one month in standard laparoscopy but with no further robotic exposure. Training included a validated laparoscopic training program including timed and scored parameters. After completion of the month-long training, the students repeated the cutting exercise using the da Vinci® robot as well as with standard laparoscopic instruments and were scored within the same parameters. Results: The mean time to completely incise the spiral robotically prior to training was 16.72 minutes with a mean of 6.21 errors. After one month of validated laparoscopic training, the mean robotic time fell to 9:03 minutes (p=0.0002) with 3.57 errors (p=0.02). Laparoscopic performance after one month of validated laparoscopic training was 13.95 minutes with 6.14 errors, which was no better than pre-training robotic performance (p=0.20) and worse than post-training robotic performance (p=0.01). Conclusions: Formal laparoscopic training improved performance of a complex robotic task. Initial robotic performance without any robotic or laparoscopic training was equivalent to standard laparoscopic performance after extensive training. Additionally, after laparoscopic training the robot allowed significantly superior speed and precision of the task. Laparoscopic training may improve proficiency in operation of the robot. This may explain the perceived ease with which robotics is adopted by laparoscopically trained surgeons and may be important in training future robotic surgeons.

Studies of laparoscopic approaches in colorectal surgery support the use of such methods. Compared with the open approach, laparoscopy reduces rates of postoperative complications and decreases length of stay, while providing equivalent oncologic outcomes. Nevertheless, much of colorectal surgery is still being performed by the open approach. This may be partly due to the technical challenges in performing laparoscopy, particularly when working in narrow spaces such as the pelvis. Moreover, some of the current literature has questioned the oncologic outcomes after laparoscopic surgery for rectal cancer. Robotic surgery has been heralded as the minimally invasive tool that can overcome these challenges. It has the advantages that it provides a three dimensional image, uses wristed instruments, and has a computer interface that allows for fluid and accurate movements. Overall, current evidence suggests that robotics is safe and feasible in colorectal surgery, and that short term and long term outcomes are comparable to those seen for laparoscopic approaches. Studies on the costs of robotic surgery show conflicting results, and this is arguably one of the biggest disadvantages of its use. Because robotic surgery is a relatively new technology, few large high quality studies are available. Most of the published studies in this area consist of retrospective reviews, case matched studies, and national database reviews. Large randomized prospective studies are needed to further support its use.

Laparoscopic surgery and robotic surgery, two forms of minimally invasive surgery (MIS), have recently experienced a large increase in utilization. Prior studies have shown that video game experience (VGE) may be associated with improved laparoscopic surgery skills; however, similar data supporting a link between VGE and proficiency on a robotic skills simulator (RSS) are lacking. The objective of our study is to determine whether volume or timing of VGE had any impact on RSS performance. Pre-clinical medical students completed a comprehensive questionnaire detailing previous VGE across several time periods. Seventy-five subjects were ultimately evaluated in 11 training exercises on the daVinci Si Skills Simulator. RSS skill was measured by overall score, time to completion, economy of motion, average instrument collision, and improvement in Ring Walk 3 score. Using the nonparametric tests and linear regression, these metrics were analyzed for systematic differences between non-users, light, and heavy video game users based on their volume of use in each of the following four time periods: past 3 months, past year, past 3 years, and high school. Univariate analyses revealed significant differences between heavy and non-users in all five performance metrics. These trends disappeared as the period of VGE went further back. Our study showed a positive association between video game experience and robotic skills simulator performance that is stronger for more recent periods of video game use. The findings may have important implications for the evolution of robotic surgery training.

The use of robotic surgery for minimally invasive procedures has increased considerably over the last decade. Robotic surgery has potential advantages compared to laparoscopic surgery but also requires new skills. Using virtual reality (VR) simulation to facilitate the acquisition of these new skills could potentially benefit training of robotic surgical skills and also be a crucial step in developing a robotic surgical training curriculum. The study’s objective was to establish validity evidence for a simulation-based test for procedural competency for the vaginal cuff closure procedure that can be used in a future simulation-based, mastery learning training curriculum.

The removal of obstacles from the surgical field is a crucial aspect of any procedure in gynecological, urological or visceral laparoscopic surgery. Reliable instruments and skilled assistance are essential for the smooth execution of procedures. Blunt forceps are commonly used to keep tissue away from the operating field. The range of existing instruments has been enhanced by the introduction of laparoscopic retractors. However, no laparoscopic retractor can be used without causing tissue damage.

Robotic surgical platforms are now in widespread use in the practice of gynecology all over the world. The introduction of robotic surgery has required some modifications of patient positioning when compared to standard laparoscopic surgery. Optimal patient positioning is likely to be the most essential step of robotic surgery as it provides the technical feasibility to have adequate access to the pelvic structures for performing the surgery. It is prudent to pay attention to preventing patient shifting in Trendelenburg position because of tendency of sliding down toward the direction of the head. Inappropriate patient positioning is associated with inadequate exposure of the operative field as well as detrimental complications that may lead to long-term side effects. These issues can be reduced with use of proper or strategic positioning technique. The purpose of this review is to highlight important points to properly position patient for robot-assisted laparoscopic benign gynecologic surgery and protect patient from position-related injuries.

Laparoscopic surgery for gastric tumor is considered a demanding procedure because of lymph node dissection and reconstruction. Billroth-I (B-I) reconstruction after laparoscopic distal gastrectomy is commonly performed extracorporeally because of the complexity of an intracorporeal procedure. Robotic surgery overcomes some limitations of laparoscopy, allowing to reproduce the basic maneuvers of open surgery. We describe a new technique to perform robotic B-I anastomosis.
