Midterm results of robot-assisted sacrocolpopexy

Robotic-assisted repair of pelvic organ prolapse: a scoping review of the literature

The purpose of this article is to perform a scoping review of the medical literature regarding the efficacy, safety, and cost of robotic-assisted procedures for repair of pelvic organ prolapse in females. Sacrocolpopexy is the “gold standard” repair for apical prolapse for those who desire to maintain their sexual function, and minimally-invasive approaches offer similar efficacy with fewer risks than open techniques. The introduction of robotic technology has significantly impacted the field, converting what would have been a large number of open abdominal sacrocolpopexy (ASC) procedures to a minimally-invasive approach in the United States. Newer techniques such as nerve-sparing dissection at the sacral promontory, use of the iliopectineal ligaments and natural orifice vaginal sacrocolpopexy may improve patient outcomes. Prolapse recurrence is consistently noted in at least 10% of patients regardless of route of mesh placement. Ancillary factors including pre-operative prolapse stage, retention of the cervix, type of mesh implant, and genital hiatus (GH) size all adversely affect surgical efficacy, while trainees do not. Minimally-invasive apical repair procedures are suited to early recovery after surgery protocols but may not be appropriate for all patients. Studies evaluating longer-term outcomes of robotic sacrocolpopexies are needed to understand the relative risk/benefit ratio of this technique. With several emerging robotic platforms with improved features and a focus on decreasing costs, the future of robotics seems bright.

Role of robotic surgery on pelvic floor reconstruction

Over the past two decades, minimally invasive surgery (MIS) abdominal surgery has increasingly been used to treat pelvic organ prolapse. Besides the several advantages associated with minimal invasiveness, this approach bridged the gap between the benefits of vaginal surgery and the surgical success rates of open abdominal procedures. The most commonly performed procedure for suspension of the vaginal apex for postoperative vaginal prolapse by robotic-assisted laparoscopy is the sacrocolpopexy. Conventional laparoscopic application of this procedure was first reported in 1994 by Nezhat et al. and had not gained widespread adoption due to lengthy learning curve associated with laparoscopic suturing. Since FDA approval of the da Vinci® robot for gynecologic surgery in 2005, minimally invasive abdominal surgery for pelvic organ prolapse has become increasingly popular, as robotic-assisted laparoscopic sacrocolpopexy is an option for those surgeons without experience or training in the conventional route. Robotic surgery has made its way into the armamentarium of POP treatment and has allowed pelvic surgeons to adapt the "gold standard" technique of abdominal sacrocolpopexy to a minimally invasive approach with improved intraoperative morbidity and decreased convalescence. In fact, repair of pelvic organ prolapse can be performed robotically, and sometimes surgeons can feel suturing and dissection during the procedures less challenging with the assistance of the robot. However, even if robotic surgery may confer many benefits over conventional laparoscopy, these advantages should continue to be weighed against the cost of the technology. To date, as long-term outcomes, evidence about robotic sacrocolpopexy for a repair of pelvic organ prolapse are not conclusive, and much more investigations are needed to evaluate subjective and objective outcomes, perioperative and postoperative adverse events, and costs associated with these procedures. It is plausible to think that the main advantage is that robotics may lead to a widespread adoption of minimally invasive techniques in the field of pelvic floor reconstructive surgery. The following review will address the development and current state of robotic assistance in treating pelvic floor reconstruction discussing available data about the techniques of robotic prolapse repair as well as morbidity, costs and clinical outcomes.

Long-term outcomes of robotic mesh sacrocolpopexy

The aim of the study is to evaluate anatomic and functional late-term outcomes of robotic mesh sacrocolpopexy (RMS) at a single tertiary-care institution. Following IRB approval, a retrospective chart review of a prospectively collected database on consecutive patients who underwent RMS for symptomatic pelvic organ prolapse and had 3 year minimum follow-up was performed. Data collected included physical examination, validated questionnaires including Urogenital Distress Inventory, Incontinence Impact Questionnaire, and global Quality of Life (QOL). The primary outcome was failure defined as the need for re-operation and/or prolapse recurrence by examination. Those with office follow-up < 36 months underwent structured phone interviews. Between 12/2007 and 2/2012, 56 women underwent RMS. Thirty women had follow-up ≥ 3 years (median 64 (IQR 48-85) months). Mean C-point went from - 2.33 (range 0 to - 5) to - 9.00 (0 to - 12) (p < 0.01), and mean QOL score from 3.93 (0-10) to 1.93 (0-8) (p < 0.01). Two developed recurrent vault prolapse later on at 26 and 34 months, respectively. Four women (13%) required surgery for secondary prolapses, with three for anterior compartment and one for posterior compartment. Sixteen of twenty six were contacted via structured phone interviews, with 14 doing well, one deceased, and one who underwent a secondary posterior compartment prolapse 6 years later at an outside facility. This long-term study indicates durability for RMS in the management of symptomatic pelvic organ prolapse.
