Reducing Length of Stay Using a Robotic-assisted Approach for Retromuscular Ventral Hernia Repair: A Comparative Analysis From the Americas Hernia Society Quality Collaborative.

OBJECTIVE: The aim of this study was to compare length of stay (LOS) after robotic-assisted and open retromuscular ventral hernia repair (RVHR). BACKGROUND: RVHR has traditionally been performed by open techniques. Robotic-assisted surgery enables surgeons to perform minimally invasive RVHR, but with unknown benefit. Using real-world evidence, this study compared LOS after open (o-RVHR) and robotic-assisted (r-RVHR) approach. METHODS: Multi-institutional data from patients undergoing elective RVHR in the Americas Hernia Society Quality Collaborative between 2013 and 2016 were analyzed. Propensity score matching was used to compare median LOS between o-RVHR and r-RVHR groups. This work was supported by an unrestricted grant from Intuitive Surgical, and all clinical authors have declared direct or indirect relationships with Intuitive Surgical. RESULTS: In all, 333 patients met inclusion criteria for a 2:1 match performed on 111 r-RVHR patients using propensity scores, with 222 o-RVHR patients having similar characteristics as the robotic-assisted group. Median LOS [interquartile range (IQR)] was significantly decreased for r-RVHR patients [2 days (IQR 2)] compared with o-RVHR patients [3 days (IQR 3), P < 0.001]. No differences in 30-day readmissions or surgical site infections were observed. Higher surgical site occurrences were noted with r-RVHR, consisting mostly of seromas not requiring intervention. CONCLUSIONS: Using real-world evidence, a robotic-assisted approach to RVHR offers the clinical benefit of reduced postoperative LOS. Ongoing monitoring of this technique should be employed through continuous quality improvement to determine the long-term effect on hernia recurrence, complications, patient satisfaction, and overall cost.

Robotic-assisted laparoscopic groin hernia repair: observational case-control study on the operative time during the learning curve.

BACKGROUND: Robotic groin hernia repair (r-TAPP) is demonstrating rapid adoption in the US. Barriers in Europe include: low availability of robotic systems to general surgeons, cost of robotic instruments, and the perception of longer operative time. METHODS: Patients undergoing r-TAPP in our start-up period were prospectively entered in the EuraHS database and compared to laparoscopic TAPP (l-TAPP) performed by the same surgeon within the context of two other prospective studies. Operations were performed with the daVinci Xi robot and the primary endpoint was skin-to-skin operative time. RESULTS: Following proctoring in September 2016 by US surgeons, 50 r-TAPP (34 unilateral and 16 bilateral) procedures have been performed up to January 2017. Mean operative time for unilateral r-TAPP was 54 min, with a decrease from 63 min for the first tertile to 44 min for the third tertile. For unilateral l-TAPP, the mean operative time was 45 min. Mean operative time for bilateral r-TAPP was 78 min, with a decrease from 90 min for the first half to 68 min for the second half. For bilateral l-TAPP, the mean operative time was 61 min. There were no intraoperative complications and no conversions to conventional laparoscopy or open surgery. The operation was performed as an outpatient in 67% of cases. Urinary retention requiring urinary catheterization was the only early postoperative complication noted in 5 patients (10.2%). At 4 week follow-up, 7 patients (14.3%) had an asymptomatic seroma, but no other complications were seen. CONCLUSION: Robotic TAPP was associated with a rapid reduction in operative time during our learning curve and afterwards the operative time to perform a robotic TAPP equals the operative time to perform a laparoscopic TAPP, both for unilateral and for bilateral groin hernia repairs. No complications related to the introduction of robotic-assisted laparoscopic groin hernia repair were observed.

Ventral Hernia Management: Expert Consensus Guided by Systematic Review.

OBJECTIVE: To achieve consensus on the best practices in the management of ventral hernias (VH). BACKGROUND: Management patterns for VH are heterogeneous, often with little supporting evidence or correlation with existing evidence. METHODS: A systematic review identified the highest level of evidence available for each topic. A panel of expert hernia-surgeons was assembled. Email questionnaires, evidence review, panel discussion, and iterative voting was performed. Consensus was when all experts agreed on a management strategy. RESULTS: Experts agreed that complications with VH repair (VHR) increase in obese patients (grade A), current smokers (grade A), and patients with glycosylated hemoglobin (HbA1C) ≥ 6.5% (grade B). Elective VHR was not recommended for patients with BMI ≥ 50 kg/m (grade C), current smokers (grade A), or patients with HbA1C ≥ 8.0% (grade B). Patients with BMI= 30-50 kg/m or HbA1C = 6.5-8.0% require individualized interventions to reduce surgical risk (grade C, grade B). Nonoperative management was considered to have a low-risk of short-term morbidity (grade C). Mesh reinforcement was recommended for repair of hernias ≥ 2 cm (grade A). There were several areas where high-quality data were limited, and no consensus could be reached, including mesh type, component separation technique, and management of complex patients. CONCLUSIONS: Although there was consensus, supported by grade A-C evidence, on patient selection, the safety of short-term nonoperative management, and mesh reinforcement, among experts; there was limited evidence and broad variability in practice patterns in all other areas of practice. The lack of strong evidence and expert consensus on these topics has identified gaps in knowledge where there is need of further evidence.

Structured Resident Training in Robotic Surgery: Recommendations of the Robotic Surgery Education Working Group.

OBJECTIVE: A universal resident robotic surgery training pathway that maximizes proficiency and safety has not been defined by a consensus of surgical educators or by surgical societies. The objective of the Robotic Surgery Education Working Group was to develop a universal curriculum pathway and leverage digital tools to support resident education. DESIGN: The two lead authors (JP and YN) contacted potential members of the Working Group. Members were selected based on their authorship of peer-review publications, their experience as minimally invasive and robotic surgeons, their reputations, and their ability to commit the time involved to work collaboratively and efficiently to reach consensus regarding best practices in robotic surgery education. The Group's approach was to reach 100% consensus to provide a transferable curriculum that could be applied to the vast majority of resident programs. SETTING: Virtual and in-person meetings in the United States. PARTICIPANTS: Eight surgeons (2 females and 6 males) from five academic medical institutions (700-1541 beds) and three community teaching hospitals (231-607 beds) in geographically diverse locations comprised the Working Group. They represented highly specialized general surgeons and educators in their mid-to-late careers. All members were experienced minimally invasive surgeons and had national reputations as robotic surgery educators. RESULTS: The surgeons initially developed and agreed upon questions for each member to consider and respond to individually via email. Responses were collated and consolidated to present on an anonymized basis to the Group during an in-person day-long meeting. The surgeons self-facilitated and honed the agreed upon responses of the Group into a 5-level Robotic Surgery Curriculum Pathway, which each member agreed was relevant and expressed their convictions and experience. CONCLUSIONS: The current needs for a universal robotic surgery training curriculum are validated objective and subjective measures of proficiency, access to simulation, and a digital platform that follows a resident from their first day of residency through training and their entire career. Refinement of current digital solutions and continued innovation guided by surgical educators is essential to build and maintain a scalable, multi-institutional supported curriculum.

Robotic-assisted onlay technique: new approach using anterior mesh positioning in ventral hernia repair-an easy way to spread robotic surgery.

There is still a lot of debate about what is the best technique for ventral hernia (VH) repair surgery. Robotic-assisted procedures are an excellent alternative to overcome the technical difficulties of regular laparoscopic surgery. The onlay technique is one of the most performed surgeries worldwide in open ventral hernia surgery, and the anatomy is easily recognized by all surgeons. Introducing the robotic onlay approach, using robotic-assisted surgery to perform ventral hernia repair with a technique is usual for most surgeons. This "new" approach may change the initial concept that minimally invasive abdominal wall surgery requires specific and tedious training and can help standardize ventral hernia repair by robotic surgery and facilitate training, allowing more surgeons to perform minimally invasive abdominal wall surgery. Finally, clinical studies are needed to measure the impact of Robotot implementation in MIS ventral hernia repair and long-term results.

How to report educational videos in robotic surgery: an international multidisciplinary consensus statement.

The swift endorsement of the robotic surgical platform indicates that it might prevail as the preferred technique for many complex abdominal and pelvic operations. Nonetheless, use of the surgical robotic system introduces further layers of complexity into the operating theatre necessitating new training models. Instructive videos with relevant exposition could be optimal for early training in robotic surgery and the aim of this study was to develop consensus guidelines on how to report a robotic surgery video for educational purposes to achieve high quality educational video outputs that could enhance surgical training. A steering group prepared a Delphi survey of 46 statements, which was distributed and voted on utilising an electronic survey tool. The selection of committee members was designed to include representative surgical trainers worldwide across different specialties, including lower and upper gastrointestinal surgery, general surgery, gynaecology and urology. 36 consensus statements were approved and classified in seven categories: author's information and video introduction, case presentation, demonstration of the surgical procedure, outcomes of the procedure, associated educational content, review of surgical videos quality and use of surgical videos in educational curricula. Consensus guidelines on how to report robotic surgery videos for educational purposes have been elaborated utilising Delphi methodology. We recommend that adherence to the guidelines presented could support advancing the educational quality of video outputs when designed for training.
