The new robotic system HUGO RAS for gynecologic surgery: First European experience from Gemelli Hospital.

OBJECTIVE: To evaluate the safety and feasibility of the new surgical robot HUGO robotic assisted surgery (RAS) in a series of gynecologic surgical procedures. METHODS: Between March and October 2022, 138 patients treated at Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy were enrolled in the study. All patients suitable for a minimally-invasive approach were prospectively included and divided into two groups: Group 1 (78 patients) made up of patients operated on for uterine and/or adnexal pathologies, and Group 2 (60 patients) made up of patients treated for pelvic organ prolapse. RESULTS: In Group 1, median docking time (DT) was 5 min and median console time (CT) was 90 min. In two patients (2.6%) redocking was necessary. In two patients (2.6%), the surgeon continued the surgery laparoscopically. Intraoperative complications occurred in two surgeries (2.6%). In Group 2, median DT was 4 min and median CT was 134.5 min. In three patients (5%), redocking was necessary. In all patients, the surgery was successfully completed robotically without intraoperative complications. CONCLUSIONS: The present study demonstrates that the new HUGO RAS system for gynecologic surgery is safe with good results in terms of surgical efficacy and perioperative outcomes. Further studies are needed to investigate its use in other technical and surgical aspects.

Pelvic floor injury during vaginal birth is life-altering and preventable: what can we do about it?

Pelvic floor disorders after childbirth have distressing lifelong consequences for women, requiring more than 300,000 women to have surgery annually. This represents approximately 10% of the 3 million women who give birth vaginally each year. Vaginal birth is the largest modifiable risk factor for prolapse, the pelvic floor disorder most strongly associated with birth, and is an important contributor to stress incontinence. These disorders require 10 times as many operations as anal sphincter injuries. Imaging shows that injuries of the levator ani muscle, perineal body, and membrane occur in up to 19% of primiparous women. During birth, the levator muscle and birth canal tissues must stretch to more than 3 times their original length; it is this overstretching that is responsible for the muscle tear visible on imaging rather than compression or neuropathy. The injury is present in 55% of women with prolapse later in life, with an odds ratio of 7.3, compared with women with normal support. In addition, levator damage can affect other aspects of hiatal closure, such as the perineal body and membrane. These injuries are associated with an enlarged urogenital hiatus, now known as antedate prolapse, and with prolapse surgery failure. Risk factors for levator injury are multifactorial and include forceps delivery, occiput posterior birth, older maternal age, long second stage of labor, and birthweight of >4000 g. Delivery with a vacuum device is associated with reduced levator damage. Other steps that might logically reduce injuries include manual rotation from occiput posterior to occiput anterior, slow gradual delivery, perineal massage or compresses, and early induction of labor, but these require study to document protection. In addition, teaching women to avoid pushing against a contracted levator muscle would likely decrease injury risk by decreasing tension on the vulnerable muscle origin. Providing care for women who have experienced difficult deliveries can be enhanced with early recognition, physical therapy, and attention to recovery. It is only right that women be made aware of these risks during pregnancy. Educating women on the long-term pelvic floor sequelae of childbirth should be performed antenatally so that they can be empowered to make informed decisions about management decisions during labor.

A unified pelvic floor conceptual model for studying morphological changes with prolapse, age, and parity.

Several 2-dimensional and 3-dimensional measurements have been used to assess changes in pelvic floor structures and shape. These include assessment of urogenital and levator hiatus dimensions, levator injury grade, levator bowl volume, and levator plate shape. We argue that each assessment reflects underlying changes in an individual aspect of the overall changes in muscle and fascial structures. Vaginal delivery, aging, and interindividual variations in anatomy combine to affect pelvic floor structures and their connections in different ways. To date, there is no unifying conceptual model that permits the evaluation of how these many measures relate to one another or that reflects overall pelvic floor structure and function. Therefore, this study aimed to describe a unified pelvic floor conceptual model to better understand how the aforementioned changes to the pelvic floor structures and their biomechanical interactions affect pelvic organ support with vaginal birth, prolapse, and age. In this model, the pelvic floor is composed of 5 key anatomic structures: the (1) pubovisceral, (2) puborectal, and (3) iliococcygeal muscles with their superficial and inferior fascia; (4) the perineal membrane or body; and (5) the anal sphincter complex. Schematically, these structures are considered to originate from pelvic sidewall structures and meet medially at important connection points that include the anal sphincter complex, perineal body, and anococcygeal raphe. The pubovisceral muscle contributes primarily to urogenital hiatus closure, whereas the puborectal muscle is mainly related to levator hiatus closure, although each muscle contributes to the other. Dorsally and laterally, the iliococcygeal muscle forms a shelflike structure in women with normal support that spans the remaining area between these medial muscles and attachments to the pelvic sidewall. Other features include the levator plate, bowl volume, and anorectal angle. The pelvic floor conceptual model integrates existing observations and points out evident knowledge gaps in how parturition, injury, disease, and aging can contribute to changes associated with pelvic floor function caused by the detachment of one or more important connection points or pubovisceral muscle failure.

Robotic docking time with the Hugo™ RAS system in gynecologic surgery: a procedure independent learning curve using the cumulative summation analysis (CUSUM).

Robot-assisted surgery has been proven to offer improvements in term of surgical learning curve and feasibility of minimally invasive surgery, but has often been criticized for its longer operative times compared to conventional laparoscopy. Additional times can be split into time required for system set-up, robotic arms docking and calibration of robotic instruments; secondly, surgeon's learning curve. One of the newest systems recently launched on the market is the Hugo™ RAS (MEDTRONIC Inc, United States). As some of the earliest adopters of the Hugo™ RAS system technology, we present our data on robotic docking learning curve for the first 192 gynecologic robotic cases performed at our institution. Our data indicates that robotic set-up and docking with the new Hugo™ RAS robotic surgical system can be performed time-effectively and that the specific robotic docking learning curve is comparable to preexisting data for other platforms. This preliminary insights into this recently released system may be worthwhile for other centers which may soon adopt this new technology and may need some relevant information on topics such as OR times. Further studies are necessary to assess the different features of the Hugo™ RAS considering other technical and surgical aspects, to fully become familiar with this novel technology.

The first 60 cases of robotic sacrocolpopexy with the novel HUGO RAS system: feasibility, setting and perioperative outcomes.

Introduction: We present the preliminary report of the first 60 cases of robotic sacrocolpopexy (RSCP) performed with a minimally invasive approach by using the new HUGO RAS system (Medtronic) with the aim of assessing its feasibility, safety and efficacy. Methods: Results in terms of operative time, intraoperative blood loss, post-operative pain, length of hospitalisation, intra and post-operative complications were comparable to previously described laparoscopic and robotic techniques. Results: Urogynecological assessment at three months follow up showed surgical anatomic success in 96.7% of patients (<2 POP-Q stage), while subjective cure rate was 98.3%. Conclusions: This is the first series analyzing RSCP outcomes for POP using the new Hugo RAS system. Our results suggest effectiveness both in objective and subjective outcomes, with minimal intra and post-operative complications. Larger series as well as longer follow-up are needed to better define advantages and possible disadvantages of this novel system. Our work may represent the basis of future studies to confirm its safety, efficacy and feasibility, and may provide technical notes for other centres that wish to perform RSCP through this innovative system.

Redo laparoscopic sacrocolpopexy for POP recurrence: Is it the right call?

OBJECTIVES: As Laparoscopic Sacrocolpopexy (LSCP) has proven to be the gold-standard for treating Pelvic Organ Prolapse, management of recurrence after its failure is a challenge with upcoming interest. In these patients, repeat LSCP might represent a suitable surgical choice. STUDY DESIGN: We present a retrospective observational study analysing safety, feasibility and outcomes of Redo LSCP. Data of 20 patients with POP recurrence who underwent previous sacrocolpopexy were recruited, and all successfully underwent a repeat LSCP. RESULTS: Median 24-months follow-up demonstrated a statistically significant improvement of objective and subjective outcome. No intra and postoperative complications were noted. Anatomical cure rate was 95%. Subjective cure rate was 100%, with a statistically significant POP symptoms resolution and improvement of voiding and storage symptoms. We compared perioperative data and outcome of Redo patients to a population who underwent LSCP for a first-time diagnosed POP. The findings demonstrated that surgery did not differ from standard procedure in terms of intra/postoperative complications, hospital stay, blood loss, except for operative time. CONCLUSIONS: Minimally invasive Redo LSCP appears to be a safe and effective procedure in treating recurrent and symptomatic Pelvic Organ Prolapse. Our series shows low recurrence rates, comparable to data from patients who underwent their primary surgery for POP.
