Evaluation of Clinical Research on Novel Multiport Robotic Platforms for Urological Surgery According to the IDEAL Framework: A Systematic Review of the Literature. EUR UROL SUPPL 2024; 67:7-25. [PMID: 39100226 PMCID: PMC11293526 DOI: 10.1016/j.euros.2024.06.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/24/2024] [Indexed: 08/06/2024] Open
Abstract
Background and objective Several novel multiport robotic systems have been developed and introduced in clinical practice after regulatory approval. The objective of this systematic review was to assess the evolution status of novel robotic platforms approved for clinical use in urological surgery according to the IDEAL framework. Methods A systematic review was conducted using the Medline and Scopus databases according to the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (CRD42024503227). Comparative or noncomparative studies reporting on any urological procedures performed with novel robotic platforms (Hugo RAS; Versius, KangDuo, Senhance, REVO-I, Avatera, Hinotori, Dexter, or Toumai) were selected and included in the analysis. Key findings and limitations Seventy-four eligible studies were included, of which 67 (90.5%) were noncomparative surgical series representing developmental or explorative studies according to the IDEAL criteria. Only one randomised controlled trial (comparing KangDuo vs da Vinci robot-assisted partial nephrectomy) was included. The trial showed comparable perioperative outcomes between the two robotic systems. Four studies assessed clinical outcomes for patients undergoing urological procedures using a REVO-I (1 study), Senhance (2 studies), or Hinotori (1 study) system in comparison to the same procedures performed using a da Vinci system. All studies revealed outcomes comparable to those with the da Vinci system. Limitations include the small sample size in all studies, and assessment of first-generation novel platforms versus the fourth-generation multiarm da Vinci system in most of the comparative studies. Conclusions and clinical implications A few poor-quality studies have compared the use of novel robotic platforms to da Vinci systems in urological surgery and demonstrated comparable results. Most studies can be classified as developmental or explorative, representing the initial steps of clinical research. Large multicentre series are needed to understand whether these novel robots could offer advantages beyond cost reductions over the da Vinci systems. Patient summary We reviewed research on new robotic systems for surgery in urology. Several studies have shown the feasibility and safety of these new robots during the most common procedures. Very few studies have assessed clinical outcomes with the new robots in comparison to the reference standard, which is a fourth-generation da Vinci robot. Large multicentre studies are needed to understand whether the new robots could offer advantages other than cost savings over the da Vinci robot.

Eur J Obstet Gynecol Reprod Biol X 2024; 23:100323. [PMID: 39091980 PMCID: PMC11292541 DOI: 10.1016/j.eurox.2024.100323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 06/08/2024] [Accepted: 06/16/2024] [Indexed: 08/04/2024] Open
Abstract
Objectives Vaginal assisted Natural Orifice Transluminal Endoscopic Surgery (NOTES) combines the benefits of vaginal and endoscopic surgery. This study presents the results of the first vaginal assisted NOTES hysterectomies (VANH) in The Netherlands. Study design A prospective cohort study was performed in two non-academic teaching hospitals in The Netherlands. Data was collected from patients who underwent a VANH for benign indications between August 2019 and April 2023. Baseline characteristics and data of intra- and postoperative surgical outcomes were recorded and analysed. The VANHs were performed by four experienced vaginal and endoscopic gynaecological surgeons. Results A total of 200 patients underwent a VANH. Indications were dysfunctional menstrual bleeding (61 %; n = 122), abnormal cervical cytology (15.5 %; n = 31), abdominal pain (11.5 %; n = 23), post ablation/sterilization pain syndrome (3.5 %; n = 7), uterine fibroids (5.0 %; n = 10), atypical endometrial hyperplasia (2.5 %; n = 5) and Lynch or BRCA gene mutation carriers (1.0 %, n = 2). The mean surgical time was 61.4 min ( ± 22.8 min) with a mean blood loss of 88 mL ( ± 89 mL) and a mean uterine weight of 150 g ( ± 112 g). In 2.0 % (n = 4) of the cases a conversion was necessary. Same day discharge (SDD) was feasible in 80.2 % (n = 105) of the patients planned in day-care. In 2.0 % (n = 4) an intra-operative complication and in 9.0 % (n = 18) a post-operative complication occurred. Conclusion This study shows vNOTES to be a safe and feasible surgical technique and can be safely implemented with appropriate patient selection and skilled surgeons. It highlights the importance of surgeon awareness of the challenges inherent in the initial stages of the implementation of a new surgical technique when performing their first vNOTES procedures. Additional randomized clinical trials are needed to show superiority of vNOTES compared to traditional surgery.

Schaefer GO. If it walks like a duck…: Monitored Emergency Use of Unregistered and Experimental Interventions (MEURI) is research. JOURNAL OF MEDICAL ETHICS 2024; 50:606-611. [PMID: 38050144 DOI: 10.1136/jme-2023-109169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 11/12/2023] [Indexed: 12/06/2023]
Abstract
Monitored Emergency Use of Unregistered and Experimental Interventions (MEURI) is an ethical framework developed by the WHO for using unproven interventions in public health emergencies outside the context of medical research. It is mainly intended for use when medical research would be impracticable, but there is still a need to systematically gather data about unproven interventions. As such, it is designed as something of a middle ground between clinical and research ethical frameworks.However, I argue that MEURI does not truly lie at the intersection of clinical care and research. Due to its intent, structure and oversight requirements, it takes on most of the crucial features of research, to the point that it is best understood as a form of research. As a result, cases where MEURI could practicably be applied should instead make use of existing research frameworks. For those circumstances where research is truly impracticable, a more straightforward oversight system than MEURI is needed. While existing practices of compassionate use have some applicability, proposals to make use of clinical ethics committees to oversee unproven interventions may help achieve the right balance in acting in a patient's best interests when the relevant evidence base is weak.

Abstract
OBJECTIVES The aim of this study is to demonstrate the ability of the Versius surgical system to successfully and safely complete a range of thoracic procedures aligned with Stage 2a (Development) of the Idea, Development, Exploration, Assessment and Long-term follow-up framework for surgical innovation. METHODS This prospective study included the first 30 consecutive patients who underwent robotic surgery with Versius by 2 surgeons without prior robotic experience between 1 April 2023 and 30 December 2023 [25 lung resections (wedge, segmentectomy and lobectomy) and 5 thymectomies]. There were no specific predetermined selection criteria for each case. The primary outcome was safe completion of the procedure without unplanned conversion. Secondary outcomes included intraoperative and postoperative complications, intraoperative device-related outcomes and pathology results. RESULTS Twenty-eight (93.3%) cases were completed without conversion. Both conversions were to thoracoscopy, one due to a 'console alarm' and the other due to pulmonary artery bleeding. In lung resections, median console time was 103 (90-129) min. Five (20%) patients experienced postoperative complications, most frequent was persistent air leak (16%). Median length-of-stay was 3 (2-4) days. Neither readmissions nor mortality was observed. In thymectomies, no intraoperative or postoperative complications, readmissions, reinterventions or mortality were observed. Median console time was 77 (75-89) min and median length of stay was 1 (1-1) day. CONCLUSIONS This phase 2a IDEAL-D study confirms lung resections and thymectomies are feasible with the use of Versius system, laying the foundation for larger phase 2b and 3 clinical studies within the IDEAL-D framework.

Abstract
BACKGROUND Robotics has increased rates of minimally invasive surgery, with distinct advantages over open surgery. However, current commercially available robotic platforms have device and system issues that limit robotic-assisted surgery expansion. OBJECTIVE To demonstrate the safety and efficacy of a novel miniaturized robotic-assisted surgery device in colectomy. DESIGN Prospective, Investigational Device Exemption clinical study following the idea, development, exploration, assessment, and long-term follow-up framework (stage 2b, exploration). SETTINGS Three centers with high-volume robotic colorectal cases and surgeons. PATIENTS Patients scheduled for a right or left colectomy for benign or malignant disease. INTERVENTION Colectomy with the novel miniaturized robotic-assisted surgery device. MAIN OUTCOME MEASURES For safety, intraoperative and device-related adverse events and 30-day morbidity. For efficacy, successful completion of predefined procedural steps without conversion. RESULTS Thirty patients (13 women, 17 men) were analyzed. The mean age was 59.4 (SD 13.4) years. Seventy percent of patients (n = 21) were overweight/obese and 53.3% of patients (n = 16) had prior abdominal surgery. Forty percent of patients had malignant and 60% had benign disease. Cases were 15 right and 15 left colectomies. Overall operative time was a median of 146 (range, 80-309) minutes; console time was 70 (range, 34-174) minutes. There were no conversions to open surgery and no intraoperative or device-related adverse events. In 100% of patients (n = 30), the primary dissection was completed, and hemostasis was maintained with the novel miniaturized robotic-assisted surgery device. The morbidity rate was 26.7% minor and 3.3% major. The median length of stay was 2 days. There were no mortalities. LIMITATIONS Single-arm study, short-term follow-up. CONCLUSIONS This first clinical study of a novel miniaturized robotic-assisted surgery device along the IDEAL framework demonstrated that it was safe and effective. Given this success, further assessment and long-term follow-up of the miniaturized robotic-assisted surgery device are planned for comparative clinical and economic effectiveness in colorectal surgery.

Abstract
Robotic Roux-en-Y gastric bypass (RRYGB) is an innovative alternative to traditional laparoscopic approaches. Literature has been published investigating its safety/efficacy; however, the quality of reporting is uncertain. This systematic review used the Idea, Development, Exploration, Assessment and Long-term follow-up (IDEAL) framework to assess the reporting quality of available literature. A narrative summary was formulated, assessing how comprehensively governance/ethics, patient selection, demographics, surgeon expertise/training, technique description and outcomes were reported. Forty-seven studies published between 2005 and 2024 were included. There was incomplete/inconsistent reporting of governance/ethics, patient selection, surgeon expertise/training and technique description, with heterogenous outcome reporting. RRYGB reporting was poor and did not align with IDEAL guidance. Robust prospective studies reporting findings using IDEAL/other guidance are required to facilitate safe widespread adoption of RRYGB and other surgical innovations.

Abstract
OBJECTIVES The objective of this study was to determine the proportion of all published core outcome set (COS) studies that include an adverse event or harm outcome, to determine the proportion of individual vs pooled harms, and to investigate characteristics that influence their inclusion. METHODS We examined the extent to which a sample of 100 published COS studies (from January 2021 to January 2023) include both pooled and individual harms in the final COS. One investigator extracted the information from the COS studies, which was cross-checked against previous COS investigational research, and where possible verified with COS authors or a pharmacologist. Using Qualtrics™, we conducted a personalized online survey of developers of the 100 COS to ask them about the importance, their experiences, and methodological approaches for dealing with harms within their COS development studies. RESULTS One hundred COS were identified from 91 separate COS studies, the majority of which considered most of the minimum standards for development. Two-thirds (65%) of the COS included at least 1 harm outcome. In total, 1104 core outcomes were identified across the 100 COS, of which 184 (17%) were harm outcomes (154 individual vs 56 pooled). Individual harms were more likely to be included in a final COS if they were developed for single treatment interventions (50%) compared to those being developed for multitreatment modalities (39%). Some COS developers adopted outcome frameworks as part of their COS development process to facilitate the inclusion of harm outcomes in their final COS. A third (33%) of respondents felt that harm outcomes should be included in all COS but over half (56%) thought this would be dependent on some aspect of the scope of the COS and improved methodology and awareness of how to deal with harm outcomes in the COS development process. CONCLUSION Harm outcomes are already included in many COS either as individual or pooled harms. It is evident that there are some challenges with regards to both the methodology and necessity to include harms within a COS (pooled or individual. COS developers should carefully consider the need to include important harms outcomes in relation to the scope of the COS that they are developing.

Abstract
PURPOSE Performing intracorporeal anastomoses in minimally invasive colon surgery appears to provide better short-term outcomes for patients with colon cancer. The aim of the study is to compare surgical aspects and short-term outcomes between intracorporeal and extracorporeal techniques in left colectomies with both laparoscopic and robotic approaches and evaluate advantages and disadvantages of intracorporeal anastomosis according to IDEAL framework (Exploration, stage 2b). METHODS This is a single center, ambispective cohort study comparing total intracorporeal anastomosis (TIA) and standard surgery with extracorporeal anastomosis (EA). Patients with colon cancer treated by left colectomy, sigmoidectomy and high anterior resection by total intracorporeal anastomosis between May 2020 and January 2023 without exclusion criteria were prospectively included in a standardized database. Short-term outcomes in the group undergoing TIA were compared with a historical EA cohort. The main assessment outcomes were intraoperative complications, postoperative morbidity according to the Clavien-Dindo scale and the comparison of pathological. We conducted a preliminary comparative study within the TIA group between approaches, a primary analysis between the two anastomotic techniques, and a propensity score matched analysis including only the laparoscopic approach, between both anastomotic techniques. RESULTS Two hundred and forty-six patients were included: 103 who underwent TIA, 35 of them with laparoscopic approach and 68 with robotic approach, and a comparison group comprising another 103 eligible consecutive patients who underwent laparoscopic EA. There were no statistically significant differences between the two groups in terms of demographic variables. No statistically significant differences were observed in anastomotic dehiscence. Intraoperative complications are fewer in the TIA group, with a higher C-Reactive Protein levels. Relevant anastomotic bleeding and the number of retrieved lymph nodes were higher in EA group. Nevertheless, no differences were observed in terms of overall morbidity. CONCLUSION Minimally invasive left colectomy with intracorporeal resection and anastomosis is technically feasible and safe suing either a laparoscopic or a robotic approach. Clinical data from this cohort demonstrate outcomes comparable to those achieved through the conventional EA procedure in relation to postoperative morbidity and oncological efficacy, with indications suggesting that the utilization of robotic-assisted techniques may play a contributing role in enhancing overall treatment outcomes.

Abstract
Neurosurgery is a field with complex ethical issues. In this article, we aim to provide an overview of key and emerging ethical issues in neurosurgery with a focus on issues relevant to practicing neurosurgeons. These issues include those of informed consent, capacity, clinical trials, emerging neurotechnology, innovation, equity and justice, and emerging bioethics areas including community engagement and organizational ethics. We argue that bioethics can help neurosurgeons think about and address these issues, and, in turn, the field of bioethics can benefit from engagement by neurosurgeons. Several ideas for increasing engagement in bioethics are proposed.

Abstract
BACKGROUND There is much heterogeneity in the instrumentation used for parenchymal transection in minimally invasive liver surgery. Instruments specifically designed for robotic parenchymal transection of the liver are lacking. We aim to gain insight into the safety and effectiveness of the SynchroSeal (Intuitive Surgical, Inc., Sunnyvale, CA), a novel bipolar electrosurgical device, in the context of liver surgery. METHODS The present study is a post-hoc analysis of prospectively collected data from patients undergoing robotic liver resection (RLR) using the SynchroSeal in two high-volume centres. The results of the SynchroSeal were compared with that of the previous generation bipolar-sealer; Vessel Sealer Extend (Intuitive Surgical, Inc., Sunnyvale, CA) using propensity score matching, after excluding the first 25 Vessel Sealer procedures per center. RESULTS During the study period (February 2020-March 2023), 155 RLRs meeting the eligibility criteria were performed with the SynchroSeal (after implementation in June 2021) and 145 RLRs with the Vessel Sealer. Excellent outcomes were achieved when performing parenchymal transection with the SynchroSeal; low conversion rate (n = 1, 0.6%), small amounts of intraoperative blood loss (median 40 mL [IQR 10-100]), short hospital stays (median 3 days [IQR 2-4]), and adequate overall morbidity (19.4%) as well as severe morbidity (11.0%). In a matched comparison (n = 94 vs n = 94), the SynchroSeal was associated with less intraoperative blood loss (48 mL [IQR 10-143] vs 95 mL [IQR 30-200], p = 0.032) compared to the Vessel Sealer. Other perioperative outcomes were similar between the devices. CONCLUSION The SynchroSeal is a safe and effective device for robotic liver parenchymal transection.

Abstract
PURPOSE Prostate-specific membrane antigen (PSMA)-targeted radioguided surgery (RGS) has gained increased interest in prostate cancer (PCa). This analysis aims to evaluate the feasibility, safety, and limitations of RGS with a novel drop-in gamma probe in primary PCa. PATIENTS AND METHODS The data of 13 patients with primary PCa undergoing RGS were analyzed retrospectively. After preoperative administration of 99mTc-PSMA-I&S, a SPECT/CT was conducted and a robotic radical prostatectomy was performed the following day including intraoperative assessment of the lymph node stations using a novel robotic drop-in gamma probe. This was followed by an extended pelvic lymph node dissection (ePLND) with ex vivo control measurement using the drop-in and a conventional rigid gamma probe. RESULTS Eleven patients (median PSA value of 11 ng/mL) had high-risk and 2 patients had intermediate-risk PCa. Overall, a median of 22 ePLND lymph nodes were dissected. In 1 patient, preoperative SPECT/CT imaging showed suspicious lymph nodes, which could be confirmed intraoperatively with the robotic drop-in probe and subsequently in the final histopathological analysis. RGS failed to identify 2 patients with micrometastases (<3 mm) preoperatively and intraoperatively. No postoperative complications related to 99mTc-PSMA-I&S RGS or ePLND occurred. CONCLUSIONS RGS with the novel drop-in gamma probe and 99mTc-PSMA-I&S allows for a reliable intraoperative screening for lymph node metastases in robot-assisted radical prostatectomy for primary PCa with an acceptable safety profile. However, limitations in the detection of micrometastases need to be overcome before omitting extended ePLND in patients at risk for lymphatic spread.

Robotic hepaticojejunostomy training in novices using robotic simulation and dry-lab suturing (ROSIM): randomized controlled crossover trial. Surg Endosc 2024:10.1007/s00464-024-10914-8. [PMID: 38958718 DOI: 10.1007/s00464-024-10914-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 05/05/2024] [Indexed: 07/04/2024]
Abstract
BACKGROUND Robotic suturing training is in increasing demand and can be done using suture-pads or robotic simulation training. Robotic simulation is less cumbersome, whereas a robotic suture-pad approach could be more effective but is more costly. A training curriculum with crossover between both approaches may be a practical solution. However, studies assessing the impact of starting with robotic simulation or suture-pads in robotic suturing training are lacking. METHODS This was a randomized controlled crossover trial conducted with 20 robotic novices from 3 countries who underwent robotic suturing training using an Intuitive Surgical® X and Xi system with the SimNow (robotic simulation) and suture-pads (dry-lab). Participants were randomized to start with robotic simulation (intervention group, n = 10) or suture-pads (control group, n = 10). After the first and second training, all participants completed a robotic hepaticojejunostomy (HJ) in biotissue. Primary endpoint was the objective structured assessment of technical skill (OSATS) score during HJ, scored by two blinded raters. Secondary endpoints were force measurements and a qualitative analysis. After training, participants were surveyed regarding their preferences. RESULTS Overall, 20 robotic novices completed both training sessions and performed 40 robotic HJs. After both trainings, OSATS was scored higher in the robotic simulation-first group (3.3 ± 0.9 vs 2.5 ± 0.8; p = 0.049), whereas the median maximum force (N) (5.0 [3.2-8.0] vs 3.8 [2.3-12.8]; p = 0.739) did not differ significantly between the groups. In the survey, 17/20 (85%) participants recommended to include robotic simulation training, 14/20 (70%) participants preferred to start with robotic simulation, and 20/20 (100%) to include suture-pad training. CONCLUSION Surgical performance during robotic HJ in robotic novices was significantly better after robotic simulation-first training followed by suture-pad training. A robotic suturing curriculum including both robotic simulation and dry-lab suturing should ideally start with robotic simulation.

Abstract
BACKGROUND Minimally invasive transcervical oesophagectomy is a surgical technique that offers radical oesophagectomy without the need for transthoracic access. The aim of this study was to evaluate the safety and feasibility of the minimally invasive transcervical oesophagectomy procedure and to report the refinement of this technique in a Western cohort. METHODS A single-centre prospective cohort study was designed as an IDEAL stage 2A study. Patients with oesophageal cancer (cT1b-4a N0-3 M0) who were scheduled for oesophagectomy with curative intent were eligible for inclusion in the study. The main outcome parameter was the postoperative pulmonary complication rate and the secondary outcomes were the anastomotic leakage, recurrent laryngeal nerve palsy, and R0 resection rates, as well as the lymph node yield. RESULTS In total, 75 patients underwent minimally invasive transcervical oesophagectomy between January 2021 and November 2023. Several modifications to the surgical technique were registered, evaluated, and implemented in the context of IDEAL stage 2A. A total of 12 patients (16%) had postoperative pulmonary complications, including pneumonia (4 patients) and pleural effusion with drainage or aspiration (8 patients). Recurrent laryngeal nerve palsy was observed in 33 of 75 patients (44%), with recovery in 30 of 33 patients (91%). A total of 5 of 75 patients (7%) had anastomotic leakage. The median number of resected lymph nodes was 29 (interquartile range 22-37) and the R0 resection rate was 96% (72 patients). CONCLUSION Introducing minimally invasive transcervical oesophagectomy for oesophageal cancer in a Dutch institution is associated with a low rate of postoperative pulmonary complications and a high rate of temporary recurrent laryngeal nerve palsy.

Abstract
PURPOSE OF REVIEW This review article focuses on bronchoscopic treatment of early-stage peripheral lung cancer. RECENT FINDINGS Bronchoscopic treatment modalities have garnered considerable attention for early-stage lung cancer. Studies using photodynamic therapy, thermal vapor ablation, laser ablation, cryoablation, and intra-tumoral injection have recently been published. However, the evidence supporting these approaches largely derives from single-arm studies with small sample sizes. Based on the IDEAL-D framework, no technology has progressed passed the idea phase (1). The main weakness of these technologies to date is lack of evidence suggesting they can achieve local control. Presently, no bronchoscopic intervention for lung cancer has sufficient data to warrant its use as part of the standard of care. SUMMARY Despite notable progress, current technologies remain suboptimal, and there is insufficient evidence to support their use outside of a research setting.

Abstract
AIMS This review aims to evaluate the feasibility of robot-assisted laparoscopic surgery (RALS) as an alternative to standard laparoscopic surgery (SLS) for the treatment of bowel deep-infiltrative endometriosis. Additionally, it aims to provide guidance for future study design, by gaining insight into the current state of research, in accordance with the IDEAL framework. METHOD A systematic review was conducted to identify relevant studies on RALS for bowel deep infiltrating endometriosis in Medline, Embase, Cochrane Library and PubMed databases up to August 2023 and reported in keeping with PRISMA guidelines. The study was registered with PROSPERO Registration: CRD42022308611 RESULTS: Eleven primary studies were identified, encompassing 364 RALS patients and 83 SLS patients, from which surgical details, operative and postoperative outcomes were extracted. In the RALS group, mean operating time was longer (235 ± 112 min) than in the standard laparoscopy group (171 ± 76 min) (p < 0.01). Patients in the RALS group experienced a shorter hospital stay (5.3 ± 3.5 days vs. 7.3 ± 4.1 days) (p < 0.01), and appeared to have fewer postoperative complications compared to standard laparoscopy. Research evidence for RALS in bowel DE is at an IDEAL Stage 2B of development. CONCLUSION RALS is a safe and feasible alternative to standard laparoscopy for bowel endometriosis treatment, with a shorter overall length of stay despite longer operating times. Further robust randomized trials recommended to delineate other potential advantages of RALS.

Abstract
BACKGROUND Although minimally invasive hepato-pancreato-biliary (MIS HPB) surgery can be performed with good outcomes, there are currently no standardized requirements for centers or surgeons who wish to implement MIS HPB surgery. The aim of this study was to create a consensus statement regarding safe dissemination and implementation of MIS HPB surgical programs. METHODS Sixteen key questions regarding safety in MIS HPB surgery were generated after a focused literature search and iterative review by three field experts. Participants for the working group were then selected using sequential purposive sampling and snowball techniques. Review of the 16 questions took place over a single 2-h meeting. The senior author facilitated the session, and a modified nominal group technique was used. RESULTS Twenty three surgeons were in attendance. All participants agreed or strongly agreed that formal guidelines should exist for both institutions and individual surgeons interested in implementing MIS HPB surgery and that routine monitoring and reporting of institutional and surgeon technical outcomes should be performed. Regarding volume cutoffs, most participants (91%) agreed or strongly agreed that a minimum annual institutional volume cutoff for complex MIS HPB surgery, such as major hepatectomy or pancreaticoduodenectomy, should exist. A smaller proportion (74%) agreed or strongly agreed that a minimum annual surgeon volume requirement should exist. The majority of participants agreed or strongly agreed that surgeons were responsible for defining (100%) and enforcing (78%) guidelines to ensure the overall safety of MIS HPB programs. Finally, formal MIS HPB training, minimum case volume requirements, institutional support and infrastructure, and mandatory collection of outcomes data were all recognized as important aspects of safe implementation of MIS HPB surgery. CONCLUSIONS Safe implementation of MIS HPB surgery requires a thoughtful process that incorporates structured training, sufficient volume and expertise, a proper institutional ecosystem, and monitoring of outcomes.

Abstract
INTRODUCTION There have been concerns around the use of synthetic mesh for stress urinary incontinence (SUI) surgery with a renewed interest in the use of autologous tissues. Recently, an autologous transobturator sling (aTOT) has been described, but the comparative data with synthetic transobturator sling (sTOT) is limited. The objective of this systematic review and meta-analysis was to assess the outcome of aTOT and compare it with sTOT. METHODS A systematic search of PubMed, Scopus, and Web of Science databases was performed and all articles available up to December 31, 2023 were screened. Studies reporting on the outcomes of aTOT and those comparing aTOT with sTOT were included. This review was performed as per Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RESULTS Eleven studies evaluating 323 patients that met the criteria were included in the final analysis, of which 6 were single arm (155 patients) and 5 were comparative. In single-arm studies, the pooled success rate, defined as negative cough stress test at 12 months follow-up was 96.8%, 3.8% had postoperative urinary retention, 6.1% had graft site-related complications and 7.6% required additional intervention for persistent SUI. The overall complication rate was 20.6% and there were no Clavien III-V complications. aTOT had similar success and complication rates when compared with sTOT but had a significantly longer operative time (weighted mean difference: 22.35 min, p < 0.00001) and superior sexual function outcomes. CONCLUSIONS aTOT, at short-term follow-up (12 months), has similar efficacy and complication rates when compared to sTOT. However, given that the data is limited and not of very good quality, and the fact that long-term follow-up is not available, further studies are required to better define the role of aTOT in the management of female patients with SUI.

Abstract
Objective The Global IDEAL Sub-Framework Study aimed to combine the intended effects of the 2009/2019 IDEAL (Idea, Development, Exploration, Assessment, Long-term study) Framework recommendations on evaluating surgical innovation with the vision outlined by the 2015 Lancet Commission on Global Surgery to provide recommendations for evaluating surgical innovation in low-resource environments. Design A mixture of methods including an online global survey and semistructured interviews (SSIs). Quantitative data were summarized with descriptive statistics and qualitative data were analyzed using the Framework Method. Participants Surgeons and surgical researchers from any country. Main outcome measures Findings were used to suggest the nature of adaptations to the IDEAL Framework to address the particular problems of evaluation in low-resource settings. Results The online survey yielded 66 responses representing experience from 40 countries, and nine individual SSIs were conducted. Most respondents (n=49; 74.2%) had experience evaluating surgical technologies across a range of life cycle stages. Innovation was most frequently adopted based on colleague recommendation or clinical evaluation in other countries. Four themes emerged, centered around: frugal innovation in technological development; evaluating the same technology/innovation in different contexts; additional methodologies important in evaluation of surgical innovation in low/middle-income countries; and support for low-income country researchers along the evaluation pathway. Conclusions The Global IDEAL Sub-Framework provides suggestions for modified IDEAL recommendations aimed at dealing with the special problems found in this setting. These will require validation in a stakeholder consensus forum, and qualitative assessment in pilot studies. From assisting researchers with identification of the correct evaluation stage, to providing context-specific recommendations relevant to the whole evaluation pathway, this process will aim to develop a comprehensive and applicable set of guidance that will benefit surgical innovation and patients globally.

Abstract
BACKGROUND Fluorescence-guided precision cancer surgery may improve survival and minimize patient morbidity. Efficient development of promising interventions is however hindered by a lack of common methodology. This methodology review aimed to synthesize descriptions of technique, governance processes, surgical learning and outcome reporting in studies of fluorescence-guided cancer surgery to provide guidance for the harmonized design of future studies. METHODS A systematic search of MEDLINE, EMBASE and CENTRAL databases from 2016-2020 identified studies of all designs describing the use of fluorescence in cancer surgery. Dual screening and data extraction was conducted by two independent teams. RESULTS Of 13,108 screened articles, 426 full text articles were included. The number of publications per year increased from 66 in 2016 to 115 in 2020. Indocyanine green was the most commonly used fluorescence agent (391, 91.8%). The most common reported purpose of fluorescence guided surgery was for lymph node mapping (195, 5%) and non-specific tumour visualization (94, 2%). Reporting about surgical learning and governance processes incomplete. A total of 2,577 verbatim outcomes were identified, with the commonly reported outcome lymph node detection (796, 30%). Measures of recurrence (32, 1.2%), change in operative plan (23, 0.9%), health economics (2, 0.1%), learning curve (2, 0.1%) and quality of life (2, 0.1%) were rarely reported. CONCLUSION There was evidence of methodological heterogeneity that may hinder efficient evaluation of fluorescence surgery. Harmonization of the design of future studies may streamline innovation.

Abstract
OBJECTIVE To report the developmental phase results of posterior rectus sheath hiatal flap augmentation (PoRSHA), a promising surgical innovation for large and recurrent paraesophageal hernias. BACKGROUND Durable hernia repair for large paraesophageal hernias continues to be a surgical challenge. PoRSHA addresses the challenges of current and historical approaches to complex paraesophageal hernias and demonstrates significant promise as a successful alternative approach. METHODS Using the IDEAL framework, we outline the technical modifications made over the first 27 consecutive cases using PoRSHA. Outcomes measured included hernia recurrence on routine imaging at 6 months and 2 years, development of a postoperative abdominal wall eventration and incidence of solid food dysphagia. RESULTS Twenty-seven patients at our single institution with type III (n=12), type IV (n=7), or recurrent (n=8) paraesophageal hernias underwent PoRSHA. Surgery was safely and successfully carried out in all cases. Stability of the technique was reached after 16 cases, resulting in 4 main repair types. At an average follow-up of 11 months, we observed no radiologic recurrences, no abdominal eventrations or hernias at the donor site, and 1 patient with occasional solid food dysphagia that resolved with dilation. CONCLUSIONS PoRSHA can not only be safely added to conventional hiatal hernia repair with appropriate training but also demonstrates excellent short-term outcomes. While the long-term durability with 5-year follow-up is still needed, here we provide cautious optimism that PoRSHA may represent a novel solution to the long-standing high recurrence rates observed with current complex PEH repair.

Orthotopic Robot-assisted Kidney Transplantation: Surgical Technique and Preliminary Results. Eur Urol 2024; 85:556-564. [PMID: 38627151 DOI: 10.1016/j.eururo.2024.03.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 03/05/2024] [Accepted: 03/28/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND AND OBJECTIVE Orthotopic kidney transplantation (KT) has been proposed as an option for patients ineligible for heterotopic KT. In this scenario, orthotopic robot-assisted KT (oRAKT) represents a novel, minimally invasive alternative to the open approach. Here we describe the largest oRAKT series of patients, with a focus on the surgical technique, perioperative surgical outcomes, and functional results. METHODS We queried prospectively maintained databases from three referral centers to identify patients who underwent oRAKT and evaluated surgical and functional outcomes. KEY FINDINGS AND LIMITATIONS Overall, 16 oRAKT procedures were performed between January 2020 and August 2023. These involved four donors after cardiovascular death, five donors after brain death, and seven living donors. All oRAKT procedures were carried out in the left renal fossa. The indication for oRAKT was extensive calcification of the external iliac vessels (100%), frequently associated with prior KT (31%). The median operative time was 295 min (interquartile range [IQR] 268-360) and the median rewarming time 48 min (IQR 40-54). Conversion to open surgery occurred in two cases (12%), and delayed graft function was observed in two cases (12%). Postoperative complications occurred in 11 patients (69%) and three (18%) experienced Clavien-Dindo grade >II complications. At median follow-up of 9 mo (IQR 7-17), 14 patients had a functioning graft and median creatinine of 1.49 mg/dl (IQR 1.36-1.72). CONCLUSIONS AND CLINICAL IMPLICATIONS Although oRAKT is a challenging procedure, it represents a feasible option for individuals ineligible for heterotopic KT and yields favorable perioperative and mid-term functional outcomes. PATIENT SUMMARY We evaluated outcomes of orthotopic robot-assisted kidney transplantation (KT), in which the native kidney is removed and the donor kidney is transplanted into its place, in patients who are not eligible for heterotopic KT, in which the native kidney is left in place and the donor kidney is transplanted into a new location. We found that robot-assisted surgery is a safe and feasible alternative to traditional open surgery for orthotopic KT.

Pilot and feasibility trials in surgery are incompletely reported according to the CONSORT checklist: a meta-research study. J Clin Epidemiol 2024; 170:111335. [PMID: 38548230 DOI: 10.1016/j.jclinepi.2024.111335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/17/2024] [Accepted: 03/20/2024] [Indexed: 04/20/2024]
Abstract
OBJECTIVES Given the key role that pilot and feasibility (PAF) trials play in addressing the challenges of surgical trials, adequate reporting completeness is essential. Our aim was to assess completeness of reporting and evaluate if the items of the Consolidated Standards of Reporting Trials (CONSORT) extension for PAF trials have been reported in surgical PAF trials. STUDY DESIGN This is a metaresearch study reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they were pilot or feasibility randomized trials evaluating a surgical intervention. The primary outcome was overall adherence to the CONSORT statement extension to randomized PAF trials checklist. A Poisson regression was performed to explore the association between research factors and reporting completeness. SETTING MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were searched from January 1-December 31, 2011 and 2021. RESULTS After screening 1991 citations, 38 studies from 2011 to 34 studies from 2021 were included. The mean CONSORT reporting score across all included studies was 21.5 (standard deviation 6.3). After excluding items that were not applicable to all studies, a mean of 20.1 (standard deviation 6.1) of 34 items (0.59) were reported. Studies published in 2021 (vs 2011) did not have a greater number of CONSORT items reported (incidence rate ratio [IRR] 1.01, 95% confidence interval [CI] 0.89-1.15). Studies registered in a clinical trial registry (IRR 1.29, 95% CI 1.12-1.48) and randomizing more than 50 patients (IRR 1.16, 95% CI 1.04-1.30) were associated with more CONSORT items reported. CONCLUSION The reporting completeness of surgical PAF trials is poor and has not improved after the publication of the CONSORT extension.

Abstract
Background Caesarean section (CS) is the most performed major surgery worldwide. Surgical techniques used for CS vary widely and there is no internationally accepted standardization. We conducted an overview of systematic reviews (SR) of randomized controlled trials (RCT) to summarize the evidence on surgical techniques or procedures related to CS. Methods Searches were conducted from database inception to 31 January 2024 in Cochrane Database of Systematic Reviews, PubMed, EMBASE, Lilacs and CINAHL without date or language restrictions. AMSTAR 2 and GRADE were used to assess the methodological quality of the SRs and the certainty of evidence at outcome level, respectively. We classified each procedure-outcome pair into one of eight categories according to effect estimates and certainty of evidence. The overview was registered at PROSPERO (CRD 42023208306). Findings The analysis included 38 SRs (16 Cochrane and 22 non-Cochrane) published between 2004-2024 involving 628 RCT with a total of 190,349 participants. Most reviews were of low or critically low quality (AMSTAR 2). The SRs presented 345 procedure-outcome comparisons (237 procedure versus procedure, 108 procedure versus no treatment/placebo). There was insufficient or inconclusive evidence for 256 comparisons, clear evidence of benefit for 40, possible benefit for 17, no difference of effect for 13, clear evidence of harm for 14, and possible harm for 5. We found no SRs for 7 pre-defined procedures. Skin cleansing with chlorhexidine, Joel-Cohen-based abdominal incision, uterine incision with blunt dissection and cephalad-caudal expansion, cord traction for placental extraction, manual cervical dilatation in pre-labour CS, changing gloves, chromic catgut suture for uterine closure, non-closure of the peritoneum, closure of subcutaneous tissue, and negative pressure wound therapy are procedures associated with benefits for relevant outcomes. Interpretation Current evidence suggests that several CS surgical procedures improve outcomes but also reveals a lack of or inconclusive evidence for many commonly used procedures. There is an urgent need for evidence-based guidelines standardizing techniques for CS, and trials to fill existing knowledge gaps.

Abstract
OBJECTIVES The development of new surgical procedures is fundamental to advancing patient care. The Idea, Developments, Exploration, Assessment and Long-term (IDEAL) framework describes study designs for stages of innovation. It can be difficult to apply due to challenges in defining and identifying innovative procedures. This study examined how the IDEAL framework is operationalised in real-world settings; specifically, the types of innovations evaluated using the framework and how authors justify their choice of IDEAL study design. DESIGN Secondary qualitative analysis of a systematic review. DATA SOURCES Citation searches (Web of Science and Scopus) identified studies following the IDEAL framework and citing any of the ten key IDEAL/IDEAL_D papers. ELIGIBILITY CRITERIA Studies of invasive procedures/devices of any design citing any of the ten key IDEAL/IDEAL_D papers. DATA EXTRACTION AND SYNTHESIS All relevant text was extracted. Three frameworks were developed, namely: (1) type of innovation under evaluation; (2) terminology used to describe stage of innovation and (3) reported rationale for IDEAL stage. RESULTS 48 articles were included. 19/48 described entirely new procedures, including those used for the first time in a different clinical context (n=15/48), reported as IDEAL stage 2a (n=8, 53%). Terminology describing stage of innovation was varied, inconsistent and ambiguous and was not defined. Authors justified their choice of IDEAL study design based on limitations in published evidence (n=36) and unknown feasibility and safety (n=32) outcomes. CONCLUSION Identifying stage of innovation is crucial to inform appropriate study design and governance decisions. Authors' rationale for choice of IDEAL stage related to the existing evidence base or lack of sufficient outcome data for procedures. Stage of innovation was poorly defined with inconsistent descriptions. Further work is needed to develop methods to identify innovation to inform practical application of the IDEAL framework. Defining the concept of innovation in terms of uncertainty, risk and degree of evidence may help to inform decision-making.

Abstract
INTRODUCTION The aim of this methodological review is to evaluate the completeness of reporting of surgical pilot and feasibility randomised trials as per the Consolidated Standards of Reporting Trials (CONSORT) extension to randomised pilot and feasibility trials. Moreover, we aim to assess for the presence of spin reporting and inconsistency between abstract and main text reporting in surgical pilot and feasibility randomised trials. METHODS AND ANALYSIS A comprehensive, electronic search strategy will be used to identify studies indexed in Medline, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) databases. Studies will be included if they are pilot or feasibility randomised trials of surgical interventions. The primary outcome will be overall CONSORT statement extension to randomised pilot and feasibility trials checklist completeness. This will be defined as trials reporting each of the 40 items in the CONSORT statement extension to randomised pilot and feasibility trials checklist. Secondary outcomes will include the reporting of individual studies as per the CONSORT extension to randomised pilot and feasibility trials, the use of spin reporting strategies, trial factors associated with reporting quality and spin strategy use, and consistency between abstract and main text reporting. Poisson and logistic regressions will be performed to explore the association between trial factors and completeness of reporting as measured by the number of reported CONSORT items. ETHICS AND DISSEMINATION This is a methodological survey that has been registered a priori on the International Prospective Register for Systematic Reviews (PROSPERO) (CRD42023475512). Local ethics approval is not required. We plan to disseminate study results through peer-reviewed publication and conference presentations.

Abstract
INTRODUCTION Hysterectomy is one of the most common surgeries performed in women. Minimally invasive methods are on the rise globally as they have been shown to decrease surgical morbidity compared with abdominal hysterectomy. Hysterectomy by vaginal natural orifice transluminal endoscopic surgery (vNOTES) is the latest innovation. It combines the vaginal approach and endoscopy via the vagina. Large pragmatic randomised controlled trials (RCTs) are lacking comparing outcomes after vNOTES, vaginal hysterectomy (VH) and laparoscopic hysterectomy (LH). METHODS Multicentre pragmatic RCT aiming to recruit 1000 women aged 18-75 years undergoing hysterectomy for benign disease. The RCT includes two identical substudies (groups A and B). If VH is considered safe and feasible, the patient will be randomised within group A (VH vs vNOTES). If VH is not considered safe or feasible, patients will be randomised within group B (LH vs vNOTES). ANALYSIS Primary outcome is the proportion of women leaving the hospital within 12 hours after surgery. Secondary outcomes are hospitalisation time, conversion rates, duration of the surgical procedure, intraoperative complications, postoperative complications and readmission. ETHICS AND DISSEMINATION The Ethical Board Committee at Imelda Hospital, Bonheiden, Belgium, has approved the research protocol 230704 (principal investigator). Before including patients, all centres will require local or national ethical approval. The results of the study will be published in international peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT05971875.

Abstract
BACKGROUND Surgical trials are recognised as inherently challenging. Pilot and feasibility studies (PAFS) are increasingly acknowledged as a key method to optimise the design and conduct of randomised trials but remain limited in surgery. We used a mixed methods approach to develop recommendations for how surgical PAFS could be optimised. METHODS The findings from a quantitative analysis of funded surgical PAFS over a 10-year period and in-depth qualitative interviews with surgeons, methodologists and funders were triangulated and synthesised with available methodological guidance on PAFS. RESULTS The synthesis informed the development of an explanatory model describing root causes and compounding challenges that contribute to how and why surgical PAFS is not currently optimised. The four root causes identified include issues relating to (i) understanding the full scope of PAFS; (ii) design and conduct of PAFS; (iii) reporting of PAFS; and (iv) lack of appreciation of the value of PAFS by all stakeholder groups. Compounding challenges relate to both cultural issues and access to and interpretation of available methodological PAFS guidance. The study findings and explanatory model were used to inform the development of a practical guidance tool for surgeons and study teams to improve research practice. CONCLUSIONS Optimisation of PAFS in surgery requires a cultural shift in research practice amongst funders, academic institutions, regulatory bodies and journal editors, as well as amongst surgeons. Our 'Top Tips' guidance tool offers an accessible framework for surgeons designing PAFS. Adoption and utilisation of these recommendations will optimise surgical PAFS, facilitating successful and efficient future surgical trials.

BMJ Open 2024; 14:e082024.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains the most common and serious complication after distal pancreatectomy. Many attempts at lowering fistula rates have led to unrewarding insignificant results as still up to 30% of the patients suffer from clinically relevant POPF. Therefore, the development of new innovative methods and procedures is still a cornerstone of current surgical research.The cavitron ultrasonic surgical aspirator (CUSA) device is a well-known ultrasound-based parenchyma transection method, often used in liver and neurosurgery which has not yet been thoroughly investigated in pancreatic surgery, but the first results seem very promising. METHODS The CUSA-1 trial is a randomised controlled pilot trial with two parallel study groups. This single-centre trial is assessor and patient blinded. A total of 60 patients with an indication for open distal pancreatectomy will be intraoperatively randomised after informed consent. The patients will be randomly assigned to either the control group with conventional pancreas transection (scalpel or stapler) or the experimental group, with transection using the CUSA device. The primary safety endpoint of this trial will be postoperative complications ≥grade 3 according to the Clavien-Dindo classification. The primary endpoint to investigate the effect will be the rate of POPF within 30 days postoperatively according to the ISGPS definition. Further perioperative outcomes, including postpancreatectomy haemorrhage, length of hospital stay and mortality will be analysed as secondary endpoints. DISCUSSION Based on the available literature, CUSA may have a beneficial effect on POPF occurrence after distal pancreatectomy. The rationale of the CUSA-1 pilot trial is to investigate the safety and feasibility of the CUSA device in elective open distal pancreatectomy compared with conventional dissection methods and gather the first data on the effect on POPF occurrence. This data will lay the groundwork for a future confirmatory multicentre randomised controlled trial. ETHICS AND DISSEMINATION The CUSA-1 trial protocol was approved by the ethics committee of the University of Heidelberg (No. S-098/2022). Results will be published in an international peer-reviewed journal and summaries will be provided in lay language to study participants and their relatives. TRIAL REGISTRATION NUMBER DRKS00027474.

Abstract
OBJECTIVE Preclinical validation study to assess the feasibility and accuracy of electromagnetic image-guided systems (EM-IGS) in orbital surgery using high-fidelity physical orbital anatomy simulators. METHODS EM-IGS platform, clinical software, navigation instruments and reference system (StealthStation S8, Medtronic) were evaluated in a mock operating theatre at the Royal Victoria Eye and Ear Hospital, a tertiary academic hospital in Dublin, Ireland. Five high-resolution 3D-printed model skulls were created using CT scans of five anonymised patients with an orbital tumour that previously had a successful orbital biopsy or excision. The ability of ophthalmic surgeons to achieve satisfactory system registration in each model was assessed. Subsequently, navigational accuracy was recorded using defined anatomical landmarks as ground truth. Qualitative feedback on the system was also attained. RESULTS Three independent surgeons participated in the study, one junior trainee, one fellow and one consultant. Across models, more senior participants were able to achieve a smaller system-generated registration error in a fewer number of attempts. When assessing navigational accuracy, submillimetre accuracy was achieved for the majority of points (16 landmarks per model, per participant). Qualitative surgeon feedback suggested acceptability of the technology, although interference from mobile phones near the operative field was noted. CONCLUSION This study suggests the feasibility and accuracy of EM-IGS in a preclinical validation study for orbital surgery using patient specific 3D-printed skulls. This preclinical study provides the foundation for clinical studies to explore the safety and effectiveness of this technology.

Abstract
OBJECTIVE To critically appraise the body of scientific literature supporting the risks and efficacy of nasoalveolar molding (NAM), specifically in contrast to alternative methods of presurgical infant orthopedics (PSIO) or to treatment without PSIO. MAIN OUTCOME MEASURES Five outcome domains were considered: nasolabial aesthetics; dentoalveolar relationship; midfacial growth; cost and burden of care; and number of anesthetic events. DESIGN MEDLINE, Embase, and Scopus were queried for articles from the first description of the Grayson-Santiago NAM technique (1993) through December 13, 2021. After the application of inclusionary and exclusionary criteria, selected articles were critically appraised using a systematic framework that included risk of bias assessment using the Cochrane RoB 2.0 and ROBINS-I tools. RESULTS A total of 88 studies were included. Level-I and -II evidence showed on par or better approximation and alveolar alignment achieved by NAM compared to other PSIO. Level-II and -III evidence showed improved nasolabial aesthetics compared to other PSIOs. Level-II and -III evidence supported no harm to maxillofacial skeletal growth through age 12. Sparse level-III evidence supported a reduced number of labial or nasal revisions following NAM. Level-II and -III evidence showed NAM requiring upfront cost and frequent appointments but reducing caregiver psychosocial burden and reducing long-term costs compared to select alternatives. Many studies carried a high risk of bias. CONCLUSIONS Current evidence supports the overall efficacy of NAM regarding short/mid-term outcomes, with a low risk of negative effects on midfacial growth or dental development. The high risk of bias discovered in many papers underscores the need for robust study design in future research.

Abstract
INTRODUCTION/BACKGROUND Enhanced Recovery After Surgery (ERAS) is a fundamental shift in perioperative care that has consistently demonstrated an improved outcome for a wide variety of surgeries in adults but has only limited evidence in the pediatric population. OBJECTIVE We aimed to assess the success with and barriers to implementation of ERAS in a prospective, multi-center study on patients undergoing complex lower urinary tract reconstruction. STUDY DESIGN Centers were directed to implement an ERAS protocol using a multidisciplinary team and quality improvement methodologies. Providers completed pre- and post-pilot surveys. An audit committee met after enrolling the first 5 patients at each center. Pilot-phase outcomes included enrollment of ≥2 patients in the first 6 months of enrollment, completion of 90 days of follow-up, identification of barriers to implementation, and protocol adherence. RESULTS A total of 40 patients were enrolled across 8 centers. The median age at surgery was 10.3 years (IQR 6.4-12.5). Sixty five percent had a diagnosis of myelomeningocele, and 33 % had a ventriculoperitoneal shunt. A bladder augmentation was performed in 70 %, Mitrofanoff appendicovesicostomy in 52 %, Monti ileovesicostomy in 15 %, and antegrade continence enema channel in 38 %. The most commonly perceived barriers to implementation on the pre-pilot survey were "difficulty initiating and maintaining compliance with care pathway" in 51 % followed by a "lack of time, money, or clinical resources" in 36 %. The pre-pilot study experience, implementation, and pilot-phase outcomes are provided in the Table. All primary and secondary outcomes were achieved. DISCUSSION The findings of the present study were similar to several small comparative studies with regard to the importance of a multidisciplinary team, strong leadership, and continuous audit for successful implementation of ERAS. Similar barriers were also encountered to other studies, which primarily related to a lack of administrative support, leadership, and buy-in from other services. The limitations of the present study included a relatively small heterogeneous cohort and absence of a comparative group, which will be addressed in the larger exploratory phase of the trial. The findings may also not be generaziable due to the need for sustainable processes that were unique to each center as well as an absence of adequate volume or resources at smaller centers. CONCLUSIONS ERAS was successfully implemented for complex lower urinary tract reconstruction across 8 centers through a multidisciplinary team, structured approach based on the local context, and focus on a continuous audit.

Abstract
Procedure-related registries in general surgical practice offer a platform for prospective trials, the pooling of data, and detailed outcome analysis. Recommendations by the Idea, Development, Exploration, Assessment, and Long-term follow-up (IDEAL) collaboration and Outcome4Medicine have further improved the uniform reporting of complications and adverse events.In the pediatric surgical network, disease-specific registries for rare and inherited congenital anomalies are gaining importance, fostering international collaborations on studies of low-incidence diseases. However, to date, reporting of complications in the pediatric surgical registries has been inconsistent. Therefore, the European Reference Network for Rare Inherited and Congenital Anomalies (ERNICA) recently endorsed the validation of the first severity grading system for children. The planned reform of the European Paediatric Surgical Audit (EPSA) registry, which includes the implementation of the Clavien-Madadi classification, represents a further effort to establish uniform outcome reporting.This article provides an overview of experiences with surgical registries and complication reporting, along with the potential application of this knowledge to future pediatric surgical practice.

Abstract
Background The introduction of vaginal natural orifice transluminal endoscopic surgery (vNOTES) to the toolbox of gynecologic surgeons has the potential to reverse the trend of vaginal hysterectomy declines. Methods This review discusses nuances of the vNOTES technique applied to hysterectomy; describes vNOTES hysterectomy, step-by-step (including tips and tricks for low- and high-complexity cases for surgeons who may want to incorporate vNOTES hysterectomy into their surgical repertoires); and examines evidence and research trends in this field. Results The descriptions in the text, figures, tables, and videos all contribute to giving readers a clear understanding of vNOTES, its advantages, limitations, and research potentials. Conclusions vNOTES hysterectomy is a unique blend of vaginal, laparoscopic, and laparoendoscopic single-site surgery (LESS) techniques and is not a new procedure, but rather another tool to use in minimally invasive gynecologic surgery.

Robotic versus open partial pancreatoduodenectomy (EUROPA): a randomised controlled stage 2b trial. THE LANCET REGIONAL HEALTH. EUROPE 2024; 39:100864. [PMID: 38420108 PMCID: PMC10899052 DOI: 10.1016/j.lanepe.2024.100864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 01/22/2024] [Accepted: 01/24/2024] [Indexed: 03/02/2024]
Abstract
Background Open partial pancreatoduodenectomy (OPD) represents the current gold standard of surgical treatment of a wide range of diseases of the pancreatic head but is associated with morbidity in around 40% of cases. Robotic partial pancreatoduodenectomy (RPD) is being used increasingly, yet, no randomised controlled trials (RCTs) of RPD versus OPD have been published, leaving a low level of evidence to support this practice. Methods This investigator-initiated, exploratory RCT with two parallel study arms was conducted at a high-volume pancreatic centre in line with IDEAL recommendations (stage 2b). Patients scheduled for elective partial pancreatoduodenectomy (PD) for any indication were randomised (1:1) to RPD or OPD with a centralised web-based tool. The primary endpoint was postoperative cumulative morbidity within 90 days, assessed via the Comprehensive Complication Index (CCI). Biometricians were blinded to the intervention, but patients and surgeons were not. The trial was registered prospectively (DRKS00020407). Findings Between June 3, 2020 and February 14, 2022, 81 patients were randomly assigned to RPD (n = 41) or OPD (n = 40), of whom 62 patients (RPD: n = 29, OPD: n = 33) were analysed in the modified intention to treat analysis. Four patients in the OPD group were randomised, but did not undergo surgery in our department and one patient was excluded in the RPD group due to other reason. Nine patients in the RPD group and 3 patients in the OPD were excluded from the primary analysis because they did not undergo PD, but rather underwent other types of surgery. The CCI after 90 days was comparable between groups (RPD: 34.02 ± 23.48 versus OPD: 36.45 ± 27.65, difference in means [95% CI]: -2.42 [-15.55; 10.71], p = 0.713). The RPD group had a higher incidence of grade B/C pancreas-specific complications compared to the OPD group (17 (58.6%) versus 11 (33.3%); difference in rates [95% CI]: 25.3% [1.2%; 49.4%], p = 0.046). The only complication that occurred significantly more often in the RPD than in the OPD group was clinically relevant delayed gastric emptying. Procedure-related and overall hospital costs were significantly higher and duration of surgery was longer in the RPD group. Blood loss did not differ significantly between groups. The intraoperative conversion rate of RPD was 23%. Overall 90-day mortality was 4.8% without significant differences between RPD and OPD. Interpretation In the setting of a very high-volume centre, both RPD and OPD can be considered safe techniques. Further confirmatory multicentre RCTs are warranted to uncover potential advantages of RPD in terms of perioperative and long-term outcomes.

European society for trauma and emergency surgery member-identified research priorities in emergency surgery: a roadmap for future clinical research opportunities. Eur J Trauma Emerg Surg 2024; 50:367-382. [PMID: 38411700 PMCID: PMC11035411 DOI: 10.1007/s00068-023-02441-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 12/28/2023] [Indexed: 02/28/2024]
Abstract
BACKGROUND European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature. METHODS Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society. RESULTS Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training. CONCLUSIONS This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.

Abstract
PURPOSE Robot-assisted kidney transplantation (RAKT) is being increasingly performed at selected referral institutions worldwide. Yet, surgical training in RAKT is still unstructured and not grounded into formal credentialing courses including simulation, lab facilities, and modular training with animal models. As such, developing standardized, modular training programs is warranted to provide surgeons with the RAKT-specific skillset needed for a "safe" learning curve. METHODS The 3-day course on RAKT developed at the EAU Skills Center in Orsi Academy was designed as a standardized, modular, step-by-step approach aiming to provide theoretical and practical skills. The course is held by expert proctors with extensive experience in RAKT. To maximize the course's usefulness, a solid knowledge of robotics and transplantation is desirable for participants. RESULTS From January 2016 to July 2023, 87 surgeons from 23 countries (of which 36% from extra-European countries) participated in the RAKT course performed at the EAU Skills Center in Orsi Academy. Of these, 58/87 (67%) were urologists, while 27/87 (31%) were general surgeons and 2/87 (2%) were vascular surgeons. To date, 18 participants (20.6%) are actively involved in RAKT programs at institutions included in the European Association of Urology (EAU) Robotic Urology Section (ERUS)-RAKT network. CONCLUSION Leveraging the potential of simulation, wet-lab training, live porcine models, and experienced proctors, the RAKT course performed at the EAU Skills Center in Orsi Academy represents the first structured teaching effort aiming to offer surgeons a full immersion in RAKT to train the core technical skills.

Abstract
BACKGROUND Introducing new procedures and challenging established paradigms requires well-designed randomised controlled trials (RCT). However, RCT in surgery present unique challenges with much of treatment tailored to the individual patient circumstances, refined by experience and limited by organisational factors. There has been considerable debate over the outcomes of arteriovenous grafts (AVG) compared to AVF, but any differences may reflect differing practice and potential variability. It is essential, therefore, when considering an RCT of a novel surgical procedure or device that quality assurance (QA) is defined for both the new approach and the comparator. The aim of this systematic review was to evaluate the QA standards performed in RCT of AVG using a multi-national, multi-disciplinary approach and propose an approach for future RCT. METHOD The methods of this have been previously registered (PROSPERO: CRD420234284280) and published. In summary, a four-stage review was performed: identification of RCT of AVG, initial review, multidisciplinary appraisal of QA methods and reconciliation. QA measures were sought in four areas - generic, credentialing, standardisation and monitoring, with data abstracted by a multi-national, multi-speciality review body. RESULTS QA in RCT involving AVG in all four domains is highly variable, often sub-optimally described and has not improved over the past three decades. Few RCT established or defined a pre-RCT level of experience, none documented a pre-trial education programme, or had minimal standards of peri-operative management, no study had a defined pre-trial monitoring programme, and none assessed technical performance. CONCLUSION QA in RCT is a relatively new area that is expanding to ensure evidence is reliable and reproducible. This review demonstrates that QA has not previously been detailed, but can be measured in surgical RCT of vascular access, and that a four-domain approach can easily be implemented into future RCT.

Abstract
Background: Advanced diagnostic bronchoscopy targeting the lung periphery has developed at an accelerated pace over the last two decades, whereas evidence to support introduction of innovative technologies has been variable and deficient. A major gap relates to variable reporting of diagnostic yield, in addition to limited comparative studies. Objectives: To develop a research framework to standardize the evaluation of advanced diagnostic bronchoscopy techniques for peripheral lung lesions. Specifically, we aimed for consensus on a robust definition of diagnostic yield, and we propose potential study designs at various stages of technology development. Methods: Panel members were selected for their diverse expertise. Workgroup meetings were conducted in virtual or hybrid format. The cochairs subsequently developed summary statements, with voting proceeding according to a modified Delphi process. The statement was cosponsored by the American Thoracic Society and the American College of Chest Physicians. Results: Consensus was reached on 15 statements on the definition of diagnostic outcomes and study designs. A strict definition of diagnostic yield should be used, and studies should be reported according to the STARD (Standards for Reporting Diagnostic Accuracy Studies) guidelines. Clinical or radiographic follow-up may be incorporated into the reference standard definition but should not be used to calculate diagnostic yield from the procedural encounter. Methodologically robust comparative studies, with incorporation of patient-reported outcomes, are needed to adequately assess and validate minimally invasive diagnostic technologies targeting the lung periphery. Conclusions: This American Thoracic Society/American College of Chest Physicians statement aims to provide a research framework that allows greater standardization of device validation efforts through clearly defined diagnostic outcomes and robust study designs. High-quality studies, both industry and publicly funded, can support subsequent health economic analyses and guide implementation decisions in various healthcare settings.

Abstract
OBJECTIVE The aim of this study was to assess the impact of high-quality evidence supporting surgical treatment of lumbar disc herniation (LDH) on healthcare practice in the Netherlands by examining changes in healthcare utilisation, including the timing of surgery, and the healthcare costs for patients with LDH. DESIGN A retrospective, cross-sectional study was performed using population-based, longitudinal data obtained from the Dutch Healthcare Authority (2007-2020) and NIVEL's primary care (2012-2020) administrative databases. SETTING The study was conducted within the healthcare system of the Netherlands. PARTICIPANTS We included adults (≥18 years) who visited a Dutch hospital or a general practitioner (GP) for lumbar degenerative disc disease. Patients with LDH were identified based on registered diagnosis code, type of surgery (discectomy) and age (<56 years). MAIN OUTCOME MEASURES The primary outcome measure was the difference in the annual number of LDH procedures following the publication of evidence-based guidelines in 2009 (comparing the periods 2007-2009 to 2017-2019). Secondary outcome measures focused on the timing of surgery and associated healthcare costs. To validate the outcomes, secondary outcomes also include the number of discectomies and the number of procedures in the younger age group (discectomies, laminectomies, and fusion surgery). RESULTS The number of patients suffering from LDH increased from 55 581 to 68 997 (+24%) between 2007 and 2019. A decrease was observed in the annual number of LDH procedures (-18%), in the number of discectomies (-22%) and in the number of procedures for patients aged <56 years (-18%). This resulted in lower healthcare costs by €10.5 million annually. In 2012, 31% of all patients <56 years had surgery before 12 weeks from diagnosis at the GP, whereas 20% did in 2019. CONCLUSIONS Healthcare utilisation for LDH changed tremendously in the Netherlands between 2007 and 2020 and seemed to be associated with the publication and implementation of evidence-based guidelines. The observed decrease in the number of procedures has been accompanied by a corresponding reduction in healthcare costs. These findings underscore the importance of adhering to evidence-based guidelines to optimise the management of patients with LDH.

Abstract
PURPOSE To analyze the results of the subscapular sling procedure developed for anterior shoulder instability in patients with less than 10% anterior glenoid bone loss. METHODS Patients were treated surgically with the arthroscopic subscapular sling procedure. A semitendinosus graft was used to reconstruct the anterior labrum and to establish a sling suspension around the upper part of the subscapularis tendon. The patients were followed up with radiographs (at 12 and 24 months). Magnetic resonance imaging (MRI) of the shoulder region and clinical examinations were performed at 3, 12, and 24 months. Recurrent dislocation was the primary endpoint. The Western Ontario Shoulder Instability Index (WOSI) and MRI results were secondary outcome measures. An independent physiotherapist assessed residual instability and range of motion. RESULTS Fifteen patients were included with a dislocation rate of 0% after 24 months follow-up. There was a significant clinical improvement of the WOSI score from 57% (904) at baseline to 88% (241) at 24 months (P < .001). The proportion of patients with an improvement in the WOSI Total score larger than the estimated minimal clinically important difference was 100% both at 12 and 24 months. MRI showed an intact sling in all patients. External rotation was not significantly reduced (52° at baseline vs 47° at 24 months, P = .211). Flexion and abduction were significantly improved from 152° to 174° (P = .001) and 141° to 170° (P < .001) after 24 months. The surgical procedures were completed without any intraoperative complications. CONCLUSIONS The subscapular sling procedure resulted in low recurrent shoulder instability and improved patient-reported outcome measures at 24 months of follow-up. LEVEL OF EVIDENCE Level IV, case series.

Abstract
The aim of awake brain surgery is to perform a maximum resection on the one hand, and to preserve cognitive functions, quality of life and personal autonomy on the other hand. Historically, language and sensorimotor functions were most frequently monitored. Over the years other cognitive functions, including music, have entered the operation theatre. Cases about monitoring musical abilities during awake brain surgery are emerging, and a systematic method how to monitor music would be the next step. According to the IDEAL framework for surgical innovations our study aims to present future recommendation based on a systematic literature search (PRISMA) in combination with lessons learned from three case reports from our own clinical practice with professional musicians (n = 3). We plead for structured procedures including individual tailored tasks. By embracing these recommendations, we can both improve clinical care and unravel music functions in the brain.

Abstract
OBJECTIVE To assess the nationwide long-term uptake and outcomes of minimally invasive distal pancreatectomy (MIDP) after a nationwide training program and randomized trial. BACKGROUND Two randomized trials demonstrated the superiority of MIDP over open distal pancreatectomy (ODP) in terms of functional recovery and hospital stay. Data on implementation of MIDP on a nationwide level are lacking. METHODS Nationwide audit-based study including consecutive patients after MIDP and ODP in 16 centers in the Dutch Pancreatic Cancer Audit (2014 to 2021). The cohort was divided into three periods: early implementation, during the LEOPARD randomized trial, and late implementation. Primary endpoints were MIDP implementation rate and textbook outcome. RESULTS Overall, 1496 patients were included with 848 MIDP (56.5%) and 648 ODP (43.5%). From the early to the late implementation period, the use of MIDP increased from 48.6% to 63.0% and of robotic MIDP from 5.5% to 29.7% ( P <0.001). The overall use of MIDP (45% to 75%) and robotic MIDP (1% to 84%) varied widely between centers ( P <0.001). In the late implementation period, 5/16 centers performed >75% of procedures as MIDP. After MIDP, in-hospital mortality and textbook outcome remained stable over time. In the late implementation period, ODP was more often performed in ASA score III-IV (24.9% vs. 35.7%, P =0.001), pancreatic cancer (24.2% vs. 45.9%, P <0.001), vascular involvement (4.6% vs. 21.9%, P <0.001), and multivisceral involvement (10.5% vs. 25.3%, P <0.001). After MIDP, shorter hospital stay (median 7 vs. 8 d, P <0.001) and less blood loss (median 150 vs. 500 mL, P <0.001), but more grade B/C postoperative pancreatic fistula (24.4% vs. 17.2%, P =0.008) occurred as compared to ODP. CONCLUSION A sustained nationwide implementation of MIDP after a successful training program and randomized trial was obtained with satisfactory outcomes. Future studies should assess the considerable variation in the use of MIDP between centers and, especially, robotic MIDP.

Abstract
INTRODUCTION The Medtronic Hugo™ Robot-assisted Surgery (RAS) system was recently approved for clinical use. We explored the safety and feasibility of this system for endometriosis surgery. The primary outcome was safe case completion without major surgical complications (Clavien-Dindo grade ≤2) and no conversion to open surgery or laparoscopy. MATERIAL AND METHODS Surgeries for endometriosis performed at the Department of Gynecology, Rigshospitalet, on the Medtronic Hugo™ RAS system were included. Two experienced robotic surgeons performed all surgeries with their usual robotic team. The variables included were patient demographics, peri- and postoperative data, complications and 30-day readmission rate. We used the IDEAL framework 1/2a for surgical innovation in this descriptive study. RESULTS The first 12 patients were included. All cases were completed without intraoperative complications or conversion. Four patients experienced Clavien-Dindo grade 1 postoperative complications. No patients were re-admitted within 30 days. Median docking time (17 minutes), console time (87.5 minutes), blood loss (40 mL) and length of hospital stay (1 day) were acceptable compared with previous literature. CONCLUSIONS In this pilot study, we found the Medtronic Hugo™ RAS system safe and feasible for robot-assisted surgery for endometriosis. The advent of new robotic systems is welcomed to accelerate the development of technology that will advance surgical care for patients across the globe.

Prolonged hypothermic machine perfusion enables daytime liver transplantation - an IDEAL stage 2 prospective clinical trial. EClinicalMedicine 2024; 68:102411.

Abstract
Background Liver transplantation is traditionally performed around the clock to minimize organ ischemic time. However, the prospect of prolonging preservation times holds the potential to streamline logistics and transform liver transplantation into a semi-elective procedure, reducing the need for nighttime surgeries. Dual hypothermic oxygenated machine perfusion (DHOPE) of donor livers for 1-2 h mitigates ischemia-reperfusion injury and improves transplant outcomes. Preclinical studies have shown that DHOPE can safely extend the preservation of donor livers for up to 24 h. Methods We conducted an IDEAL stage 2 prospective clinical trial comparing prolonged (≥4 h) DHOPE to conventional (1-2 h) DHOPE for brain-dead donor livers, enabling transplantation the following morning. Liver allocation to each group was based on donor hepatectomy end times. The primary safety endpoint was a composite of all serious adverse events (SAE) within 30 days after transplantation. The primary feasibility endpoint was defined as the number of patients assigned and successfully receiving a prolonged DHOPE-perfused liver graft. Trial registration at: WHO International Clinical Trial Registry Platform, number NL8740. Findings Between November 1, 2020 and July 16, 2022, 24 patients were enrolled. The median preservation time was 14.5 h (interquartile range [IQR], 13.9-15.5) for the prolonged group (n = 12) and 7.9 h (IQR, 7.6-8.6) for the control group (n = 12; p = 0.01). In each group, three patients (25%; 95% CI 3.9-46%, p = 1) experienced a SAE. Markers of ischemia-reperfusion injury and oxidative stress in both perfusate and recipients were consistently low and showed no notable discrepancies between the two groups. All patients assigned to either the prolonged group or control group successfully received a liver graft perfused with either prolonged DHOPE or control DHOPE, respectively. Interpretation This first-in-human clinical trial demonstrates the safety and feasibility of DHOPE in prolonging the preservation time of donor livers to enable daytime transplantation. The ability to extend the preservation window to up to 20 h using hypothermic oxygenated machine preservation at a 10 °C temperature has the potential to reshape the landscape of liver transplantation.

Lesion detection in epilepsy surgery: Lessons from a prospective evaluation of a machine learning algorithm. Dev Med Child Neurol 2024; 66:216-225. [PMID: 37559345 DOI: 10.1111/dmcn.15727] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 06/11/2023] [Accepted: 07/03/2023] [Indexed: 08/11/2023]
Abstract
AIM To evaluate a lesion detection algorithm designed to detect focal cortical dysplasia (FCD) in children undergoing stereoelectroencephalography (SEEG) as part of their presurgical evaluation for drug-resistant epilepsy. METHOD This was a prospective, single-arm, interventional study (Idea, Development, Exploration, Assessment, and Long-Term Follow-Up phase 1/2a). After routine SEEG planning, structural magnetic resonance imaging sequences were run through an FCD lesion detection algorithm to identify putative clusters. If the top three clusters were not already sampled, up to three additional SEEG electrodes were added. The primary outcome measure was the proportion of patients who had additional electrode contacts in the SEEG-defined seizure-onset zone (SOZ). RESULTS Twenty patients (median age 12 years, range 4-18 years) were enrolled, one of whom did not undergo SEEG. Additional electrode contacts were part of the SOZ in 1 out of 19 patients while 3 out of 19 patients had clusters that were part of the SOZ but they were already implanted. A total of 16 additional electrodes were implanted in nine patients and there were no adverse events from the additional electrodes. INTERPRETATION We demonstrate early-stage prospective clinical validation of a machine learning lesion detection algorithm used to aid the identification of the SOZ in children undergoing SEEG. We share key lessons learnt from this evaluation and emphasize the importance of robust prospective evaluation before routine clinical adoption of such algorithms. WHAT THIS PAPER ADDS The focal cortical dysplasia detection algorithm collocated with the seizure-onset zone (SOZ) in 4 out of 19 patients. The algorithm changed the resection boundaries in 1 of 19 patients undergoing stereoelectroencephalography for drug-resistant epilepsy. The patient with an altered resection due to the algorithm was seizure-free 1 year after resective surgery. Overall, the algorithm did not increase the proportion of patients in whom SOZ was identified.
