Introduction: Whilst the use ofrobotics in the management of female pelvic organ prolapse (POP) isincreasing there is a paucity of data concerning efficiency andefficacy. Criticisms of RCT’s include the variance in surgeonexperience resulting in varying outcome measures such as wide rangesin operating time and complication rates.
Objective: Thepurpose of this prospective cohort study is to provide realisticoutcomes measures from different European centres with experiencedrobotic surgeons.
Methods: All consecutive patientsundergoing a Robotic procedure for uterovaginal prolapse from 2008until 2015 in two tertiary referral units in Europe were enrolled(N=501). All surgery was performed with the da Vinci Si-HD® byexperienced robotic laparoscopic urogynaecologists. For thesuspension a polyprolene mesh was used. The primary outcomes of thisstudy were the anatomic cure rates, safety of the procedure andintra-operative variables such as blood loss and operation time. Thesimplified Pelvic Organ Prolapse Quantification (POP-Q)1,was used to describe the anatomical cure after 1 year offollow-up.
Results: In total 501 patients were included.The median follow-up time was 14.0 months [range 8.0-44.4]. 68Patients were lost to follow-up (13.6%). Patient characteristics arelisted in table 1 and the operative data in table 2. Anatomicresults The median simplified POP-Q improved significantlyfor all four anatomic landmarks (table 3; p<0.0005).Intra-operative complications Twenty intra-operativecomplications were identified (4.0%), eight bladder lesions, of whichone resulted in a conversion and one had a concomitant conversion dueto adhesions. There were two small bowel serosa tears, which wererepaired intraoperatively. Eight surgeries were converted; one forbleeding from the presacral venous plexus, one due to ventilationproblems, one after a bladder lesion as above, three due to adhesionsand two for other reasons. One surgery was cancelled because ofventilation problems. The last complication occurred during a surgerywith massive adhesions, mesh placement on the anterior vaginal wallwas impossible; a small anterior wall colpotomy was made.Postoperative complications There were 38 (7.6%) earlypostoperative complications, most being small complications requiringno or a small intervention. Six (1.2%) patients had a severecomplication (Clavien Dindo Classification ≥3; table 4). Atfollow-up nine patients were identified with mesh erosion (1.8%) ofwhich two were exposed sutures (0.4%). Five patients requiredsurgical removal of the mesh or part of the mesh.

Conclusions: Currently thisis the largest prospective study assessing the robotic approach forprolapse. The results show the robot provides a safe, minimallyinvasive approach to apical prolapse, without increasing morbidity ormortality. The anatomic cure rates at one year show a significantimprovement. Furthermore, there is a reduced mesh erosion ratecompared to the vaginal route
