Robot-assisted Transvaginal Single-site Sacrocolpopexy for Pelvic Organ Prolapse

Study Objective To demonstrate stepwise techniques for the successful use of the laparoscopic single-site technique for safely performing transvaginal sacrocolpopexy for pelvic organ prolapse. Design Stepwise demonstration with narrated video footage (Canadian Task Force classification III). Setting Academic tertiary care hospital. The patient, aged 69 years gravida 2 para 2-0-0-2 with a history of SVD × 2, presented with symptomatic stage II anterior vaginal prolapse (Aa +1) and stage II posterior vaginal prolapse (Ap −1). The preoperative vaginal length was measured at 9 cm. Interventions Laparoscopic transvaginal single-site sacrocolpopexy has been demonstrated to be feasible and safe in the surgical management of pelvic organ prolapse. However, the retroperitoneal dissection or suturing/knot tying can be technically challenging to perform, especially in the event of an anatomic variation of a deeply angled S1 vertebra. Wristed robotic instrumentation may overcome some of these obstacles and result in easier suturing and knot tying. Integration of a robotic platform for sacrocolpopexy is a novel alternative minimally invasive approach that is more cosmetic, safer, and effective. Several helpful techniques in robot-assisted transvaginal single-site include the following: (1)The use of a 30°-angled scope alternating between “facing up” and “facing down” depending on the need for dissection or suturing. (2) The use of 3-dimensional visualization with a robotic camera that can highlight the depth of the surgical anatomy, therefore facilitating easier identification in the dissection of a surgical pedicle. (3) The use of wristed instruments that permit increased articulation and triangulation that are lacking in traditional laparoscopic single-site surgery, allowing for much easier and proficient suturing and knot tying. (4) Integration of the robotic platform that stabilizes the fine motor movement in a surgeon's hands improving the precision of the suturing and knot tying. The procedure was successfully performed in approximately 227 minutes with a measured postoperative vaginal length of 7 cm. The patient's postoperative pelvic organ prolapse quantification was stage 0. Conclusion Robot-assisted transvaginal single-site sacrocolpopexy for pelvic organ prolapse is feasible, effective, and safe in patients with pelvic organ prolapse. Patients experience improved cosmesis, decreased postoperative pain, and faster recovery compared with abdominal sacrocolpopexy.
