1. The metabolic fate of the substituted cinnamic acid ester, Ro 03-6037, has been examined in rat, mouse, baboon, dog, marmoset, rabbit and man. 2. All species are capable of reducing the cinnamate double bond, but the subsequent one-carbon fragment loss can be carried out only by rat, dog, rabbit and marmoset. 3. The inability of man, as well as baboon and mouse, to perform this terminal metabolic step, which results in formation of the active anti-inflammatory agent, renders the compound unsuitable as a drug for humans. 4. Reduction of the double bond is not carried out by gut flora. 5. An h.p.l.c. analytical method is described for estimation of the metabolites in biological fluids.

A high proportion of an oral dose of 14C-debrisoquine sulfate is excreted in the urine by rat and man. The urinary radioactivity consists of a mixture of unchanged drug and polar, water-soluble metabolites which cannot be extracted into organic solvents. Treatment of methanolic extracts of the freeze dried urine with acetylacetone incorporates the amidino group of debrisoquine and these metabolites into a 4,6-dimethylpyrimidine ring, and yields derivatives which can be readily extracted from aqueous solution. Gas-liquid chromatographic-mass spectrometric studies of these extracts have shown that in both species: 1) the major metabolite is formed by 4-hydroxylation of debrisoquine; 2) a significant proportion of the dose is excreted as acidic metabolites, formed by opening the tetrahydroisoquinoline ring; 3) trace amounts of phenolic metabolites (5-, 6-, 7-, and 8-hydroxydebrisoquines) are also excreted.

- Abstract
Clinical guidelines are evidence-based recommendations developed by healthcare organizations or expert panels to assist healthcare providers and patients in making appropriate and reliable decisions regarding specific health conditions, aiming to enhance the quality of healthcare by promoting best practices, reducing variations in care, and at the same time, allowing tailored clinical decision-making. European Hernia Society (EHS) guidelines aim to provide surgeons a reliable set of answers to their pertinent clinical questions and a tool to base their activity as experts in the management of abdominal wall defects. The traditional approach to guideline production is based on gathering key opinion leader in a particular field, to address a number of key questions, appraising papers, presenting evidence and produce final recommendations based on the literature and consensus. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) method offers a transparent and structured process for developing and presenting evidence summaries and for carrying out the steps involved in developing recommendations. Its main strength lies in guiding complex judgments that balance the need for simplicity with the requirement for complete and transparent consideration of all important issues. EHS guidelines are of overall good quality but the application of GRADE method, began with EHS guidelines on open abdomen, and the increasing adherence to the process, has greatly improved the reliability of our guidelines. Currently, the need to application of this methodology and the creation of stable and dedicated group of researchers interested in following GRADE in the production of guidelines has been outlined in the literature. Considering that the production of clinical guidelines is a complex process, this paper aim to highlights the primary features of guideline production, GRADE methodology, the challenges associated with their adoption in the field of hernia surgery and the project of the EHS to establish a stable guidelines committee to provide technical and methodological support in update of previously published guideline or the creation of new ones., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Stabilini, Antoniou, Berrevoet, Boermeester, Bracale, de Beaux, East, Gök, Lopez Cano, Muysoms, Capoccia Giovannini and Simons.)

- Abstract
Background: Abdominal wall surgery (AWS) is characterised by the increasing caseload and the complexity of the surgical procedures. The introduction of a tailored approach to AWS utilising laparoendoscopic, robotic and/or open techniques requires the surgeon to master several surgical techniques. All of which have an associated learning curve, and the necessary knowledge/experience to know which operation is the right one for the individual patient. However, the reality in general surgery training shows that training in just a limited number of procedures is not enough. By the end of general surgery training, many chief residents do not feel they are yet ready to carry out surgery independently. Therefore, hernia surgery experts and societies have called for the introduction of a Fellowship in Abdominal Wall Surgery. Methods: The UEMS (Union Européenne des Médecins Spécialistes, European Union of Medical Specialists) in collaboration with the European Hernia Society (EHS) introduced a fellowship by examination in 2019. As a prerequisite, candidates must complete further training of at least 2 years with a special focus on abdominal wall surgery after having completed their training in general surgery. To be eligible for the examination, candidates must provide evidence of having performed 300 hernia procedures. In addition, candidates must have accrued sufficient "knowledge points" by attending abdominal wall surgery congresses, courses and clinical visitations, and engaged in scientific activities. On meeting the requirements, a candidate may be admitted to the written and oral examination. Results: To date, three examinations have been held on the occasion of the Annual Congress of the European Hernia Society in Copenhagen (2021), Manchester (2022) and Barcelona (2023). Having met the requirements, 48 surgeons passed the written and oral examination and were awarded the Fellow European Board of Surgery - Abdominal Wall Surgery certificate. During this time period, a further 25 surgeons applied to sit the examination but did not fulfil all the criteria to be eligible for the examination. Fifty experienced abdominal wall surgeons applied to become an Honorary Fellow European Board of Surgery - Abdominal Wall Surgery . Fourty eight were successful in their application. Conclusion: The Fellowship of the European Board of Surgery - Abdominal Wall Surgery by examination has been successfully introduced at European level by the joint work of the UEMS and the EHS. The examination is also open to surgeons who work outside the European area, if they can fulfil the eligibility criteria., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Köckerling, Morales-Conde, Simons, Casanova, East, de Beaux, Henriksen, Roka and Felice.)

- Abstract
Background: There is a reasonable body of evidence around oral/dental health and implant infection in orthopaedic and cardiovascular surgery. Another large area of surgical practice associated with a permanent implant is mesh hernia repair. This study aimed to review the evidence around oral/dental health and mesh infection., Methods: The research protocol was registered in PROSPERO (CRD42022334530). A systematic review of the literature was undertaken according to the PRISMA 2020 statement. The initial search identified 582 publications. A further four papers were identified from references. After a review by title and abstract, 40 papers were read in full text. Fourteen publications were included in the final review, and a total of 47,486 patients were included., Results: There is no published evidence investigating the state of oral hygiene/health and the risk of mesh infection or other infections in hernia surgery. Improvement in oral hygiene/health can reduce surgical site infection and implant infection in colorectal, gastric, liver, orthopaedic and cardiovascular surgery. Poor oral hygiene/health is associated with a large increase in oral bacteria and bacteraemia in everyday activities such as when chewing or brushing teeth. Antibiotic prophylaxis does not appear to be necessary before invasive dental care in patients with an implant., Conclusion: Good oral hygiene and oral health is a strong public health message. The effect of poor oral hygiene on mesh infection and other complications of mesh hernia repair is unknown. While research is clearly needed in this area, extrapolating from evidence in other areas of surgery where implants are used, good oral hygiene/health should be encouraged amongst hernia patients both prior to and after their surgery., (© 2023.

- Abstract
Introduction: Hernia Basecamp is an online learning platform hosted within the WebSurg website. One of the drivers of its development was to cover the syllabus of the UEMS AWS examination, but it is a learning resource in its own right. There are currently 205 video lectures, with a number of them selected to create 10 modules of 3 h each with UEMS CME accreditation. The aim of this study was to review the Hernia Basecamp usage since launch in June 2021. Methods: The Hernia Basecamp WebSurg platform was interrogated using Matomo Analytics in January 2023 (19 month period since launch). Data on the number of visits, pages looked at and time spent on the platform per visit, along with the number of CME modules taken and passed were collected. Results: Users from 146 countries visited the Hernia Basecamp site 17,171 times (6,586 times, 38.4% in first 9 months). The top 5 countries by visitors were the United Kingdom, Mexico, Spain, United States and Germany (accounting for 29.4% of the visits). The average time spent per visit was 11 min 37 s (range: 47 s-49 min 4 s), and the number of pages/videos viewed per visit was 8.1 (range: 2-21). The number of UEMS CME modules taken was 675, and 326 (48%) of these tests were passed. Conclusion: In the first 19 months from launch, Hernia Basecamp provided over 3,000 h of hernia education. The UEMS approved CME accreditation tests were commonly used., Competing Interests: BE and AdB received payment from Medtronic to develop Hernia Basecamp. BE is Secretary for Quality on the European Hernia Society Board and Co-secretary on the UEMS Executive Committee. AdB is General Secretary on the European Hernia Society Board and Co-treasurer on the UEMS Executive Committee. SB, TP, and GT are employees of IRCAD, CA and RK are employees of Medtronic., (Copyright © 2023 de Beaux, Becker, Parent, Temporal, Kummer, Allouard and East.)

- Abstract
Background: Groin hernia repair is one of the most common operations performed globally, with more than 20 million procedures per year. The last guidelines on groin hernia management were published in 2018 by the HerniaSurge Group. The aim of this project was to assess new evidence and update the guidelines. The guideline is intended for general and abdominal wall surgeons treating adult patients with groin hernias., Method: A working group of 30 international groin hernia experts and all involved stakeholders was formed and examined all new literature on groin hernia management, available until April 2022. Articles were screened for eligibility and assessed according to GRADE methodologies. New evidence was included, and chapters were rewritten. Statements and recommendations were updated or newly formulated as necessary., Results: Ten chapters of the original HerniaSurge inguinal hernia guidelines were updated. In total, 39 new statements and 32 recommendations were formulated (16 strong recommendations). A modified Delphi method was used to reach consensus on all statements and recommendations among the groin hernia experts and at the European Hernia Society meeting in Manchester on October 21, 2022., Conclusion: The HerniaSurge Collaboration has updated the international guidelines for groin hernia management. The updated guidelines provide an overview of the best available evidence on groin hernia management and include evidence-based statements and recommendations for daily practice. Future guideline development will change according to emerging guideline methodology., (© The Author(s) 2023. Published by Oxford University Press on behalf of BJS Society Ltd.)

- Abstract
Background: There is an increasing number of patients following hernia surgery with implanted mesh reporting symptoms that could indicate autoimmune or allergic reactions to mesh. 'Allergy' to metals, various drugs, and chemicals is well recognised. However, hypersensitivity, allergy or autoimmunity caused by surgical mesh has not been proven by a scientific method to date. The aim of this study was twofold: to describe the pathophysiology of autoimmunity and foreign body reaction and to undertake a systematic review of surgical mesh implanted at the time of hernia repair and the subsequent development of autoimmune disease., Methods: A systematic review using the PRISMA guidelines was undertaken. Pubmed (Medline), Google Scholar and Cochrane databases were searched for all English-written peer-reviewed articles published between 2000 and 2021. The search was performed using the keywords "hernia", "mesh", "autoimmunity", "ASIA", "immune response", "autoimmune response"., Results: Seven papers were included in the final analysis-three systematic reviews, three cohort studies and one case report. Much of the current data regarding the association of hernia mesh and autoimmunity relies on retrospective cohort studies and/or case reports with limited availability of cofounding factor data linked to autoimmune disease such as smoking status or indeed a detailed medical history of patients. Three systematic reviews have discussed this topic, each with a slightly different approach and none of them has identified causality between the use of mesh and the subsequent development of autoimmune disease., Conclusion: There is little evidence that the use of polypropylene mesh can lead to autoimmunity. A large number of potential triggers of autoimmunity along with the genetic predisposition to autoimmune disease and the commonality of hernia, make a cause and effect difficult to unravel at present. Biomaterials cause foreign body reactions, but a chronic foreign body reaction does not indicate autoimmunity, a common misunderstanding in the literature., (© 2023. The Author(s).)

- Abstract
The recently emerged novel coronavirus, "severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)," caused a highly contagious disease called coronavirus disease 2019 (COVID-19). It has severely damaged the world's most developed countries and has turned into a major threat for low- and middle-income countries. Since its emergence in late 2019, medical interventions have been substantial, and most countries relied on public health measures collectively known as nonpharmaceutical interventions (NPIs). We aimed to centralize the accumulative knowledge of NPIs against COVID-19 for each country under one worldwide consortium. International COVID-19 Research Network collaborators developed a cross-sectional online survey to assess the implications of NPIs and sanitary supply on the incidence and mortality of COVID-19. The survey was conducted between January 1 and February 1, 2021, and participants from 92 countries/territories completed it. The association between NPIs, sanitation supplies, and incidence and mortality were examined by multivariate regression, with the log-transformed value of population as an offset value. The majority of countries/territories applied several preventive strategies, including social distancing (100.0%), quarantine (100.0%), isolation (98.9%), and school closure (97.8%). Individual-level preventive measures such as personal hygiene (100.0%) and wearing facial masks (94.6% at hospitals; 93.5% at mass transportation; 91.3% in mass gathering facilities) were also frequently applied. Quarantine at a designated place was negatively associated with incidence and mortality compared to home quarantine. Isolation at a designated place was also associated with reduced mortality compared to home isolation. Recommendations to use sanitizer for personal hygiene reduced incidence compared to the recommendation to use soap. Deprivation of masks was associated with increased incidence. Higher incidence and mortality were found in countries/territories with higher economic levels. Mask deprivation was pervasive regardless of economic level. NPIs against COVID-19 such as using sanitizer, quarantine, and isolation can decrease the incidence and mortality of COVID-19., (© 2022 Wiley Periodicals LLC.)

- Abstract
Introduction: Chronic pain is a distressing complication that can occur after inguinal hernia repair, affecting between 5% and 20% of patients as reported in literature. There are several reasons for chronic pain, including peripheral nerve irritation caused by surgical mesh or stitches. Preoperative pain is a risk factor for chronic pain., Case Report: We present the case of a 59-year-old man who experienced chronic inguinal pain following Lichtenstein hernia repair. Conservative therapy was ineffective, and he subsequently underwent triple neurectomy without removal of the original polypropylene mesh. The patient experienced significant pain relief immediately after the surgery. There was no reported pain 1 month and 1 year post-surgery., Conclusion: The management of patients with chronic pain following hernia repair should be comprehensive and, ideally, centralized. Conservative procedures should be attempted first, but neurectomy and mesh removal may be necessary in cases where conservative measures are unsuccessful.

127. Thoughts on Trocar Site Hernia Prevention. A Narrative Review.
- Author
-
de Beaux AC and East B
- Abstract
Background: Laparoscopic and robot-assisted surgery is now common place, and each trocar site is a potential incisional hernia site. A number of factors increase the risk of trocar site hernia (TSH) at any given trocar site. The aim of this paper is to explore the literature and identify the patients and the trocar sites at risk, which may allow target prevention strategies to minimise TSH. Methods: A pub med literature review was undertaken using the MeSH terms of "trocar" OR "port-site" AND "hernia." No qualifying criteria were applied to this initial search. All abstracts were reviewed by the two authors to identify papers for full text review to inform this narrative review. Results: 961 abstracts were identified by the search. A reasonable quality systematic review was published in 2012, and 44 additional more recent publications were identified as informative. A number of patient factors, pre-operative, intra-operative and post-operative factors were identified as possibly or likely increasing the risk of TSH. Their careful management alone and more likely in combination may help reduce the incidence of TSH. Conclusion: Clinically symptomatic TSH is uncommon, in relation to the many trocars inserted every day for "keyhole" surgery, although it is a not uncommon hernia to repair in general surgical practice. There are patients inherently at risk of TSH, especially at the umbilical location. It is likely, that a multi-factored approach to surgery, will have a cumulative effect at reducing the overall risk of TSH at any trocar site, including choice of trocar type and size, method of insertion, events during the operation, and decisions around the need for fascial closure and how this is performed following trocar removal., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 de Beaux and East.)

- Abstract
Background: Robot assisted laparoscopic abdominal wall surgery (RAWS) has seen a rapid adoption in recent years. The safe introduction of the robot platform in the treatment of abdominal wall hernias is important to safeguard the patient from harm during the learning curve. The scope of this paper is to describe the current European training curriculum in RAWS. Methods and Analysis: The pathway to competence in RAWS will depend on the robot platform, experience in other abdominal procedures (novice to expert) and experience in the abdominal wall repair techniques. An overview of the learning curve effect in the initial case series of several early adopters in RAWS was reviewed. In European centres, current training for surgeons wanting to adopt RAWS is managed by the specific technology-based training organized by the company providing the robot. It consists of four phases where phases I and II are preclinical, while phases III and IV focus on the introduction of the robotic platform into surgical practice. Conclusion: On behalf of the Robotic Surgery Task Force of the European Hernia Society (EHS) we believe that the EHS should play an important role in the clinical phases III and IV training. Courses organized in collaboration with the robot provider on relevant surgical anatomy of the abdominal wall and procedural steps in complex abdominal wall reconstruction like transversus abdominis release are essential. Whereas the robot provider should be responsible for the preclinical phases I and II to gain familiarity in the specific robot platform., Competing Interests: MV reports future participation in the Advisory Board of Medtronic.

- Abstract
Aim The coronavirus disease 2019 (COVID-19) pandemic resulted in a lockdown in South East Scotland on 23 March 2020. This had an impact on the volume of benign elective surgery able to be undertaken. The degree to which this reduced hernia surgery was unknown. The aim of this study was to review the hernia surgery workload in the Lothian region of Scotland and assess the impact of COVID-19 on hernia surgery. Methods The Lothian Surgical Audit database was used to identify all elective and emergency hernia operations over a six-month period from 23 March 2020 and for the same time period in 2019. Data were collected on age, gender, anatomical location of the hernia, hernia repair technique, and whether elective or emergency operation. Statistical analysis was performed using the chi-squared test in R-Studio, with a p-value of <0.05 accepted as statistically significant. Results The total number of hernia repairs reduced considerably between 2019 and 2020 (570 vs 149). The majority of this can be explained by a decrease in elective operating (488 vs 87), with the percentage of elective repairs reducing significantly from 85.6% to 58.4% (p<0.001). The inguinal hernia subgroup had a 24% rise in emergency operations from 21 to 26 operations, despite a reduction from 270 to 84 total inguinal repairs. There were just two elective hernia repairs carried out in the first three months of the 2020 study period (5.6% of all operations for April-June) compared to 265 (87.7%) for the same period in 2019 (p<0.001). No statistically significant differences were observed in the rates of laparoscopic versus open operating techniques across the two study periods on any analysis. The age and gender of the patients were similar over the two time periods. Conclusion The COVID-19 pandemic led to a marked reduction in the number of elective hernia repairs (especially incisional hernia surgery), with the effect most pronounced over the first three months of lockdown. Despite an overall reduction in total emergency operative figures, possibly due to more widespread use of non-operative strategies, there was still an increase in emergency inguinal hernia repairs during the lockdown. Further studies are needed to evaluate if the delays to elective operating will result in a long-term increase in the rates of emergency presentation., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Ewing et al.)

- Abstract
Background: Ventral hernia repair is one of the most commonly performed surgical procedures worldwide. To reduce the risk of complications, pre- and intra-operative strategies have received increasing focus in recent years. To assess possible preventive surgical strategies, this European Hernia Society endorsed project was launched. The aim of this review was to evaluate the current literature focusing on pre- and intra-operative strategies for surgical site occurrences (SSO) and specifically surgical site infection (SSI) in ventral hernia repair., Methods: A systematic review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases used were Pubmed and Web of Science. Original retrospective or prospective human adult studies describing at least one intra-operative intervention to reduce SSO after ventral hernia repair were considered eligible., Results: From a total of 4775 results, a total of 18 papers were considered suitable after full text reading. Prehospital chlorhexidine gluconate (CHG) scrub appears to increase the risk of SSO in patients undergoing ventral hernia repair, while there is no association between any type of surgical hat worn and the incidence of postoperative wound events. Intraoperative measures as prophylactic negative pressure therapy, surgical drain placement and the use of quilt sutures seem beneficial for decreasing the incidence of SSO and/or SSI. No positive effect has been shown for antibiotic soaking of a synthetic mesh, nor for the use of fibrin sealants., Conclusion: This review identified a limited amount of literature describing specific preventive measures and techniques during ventral hernia repair. An advantage of prophylactic negative pressure therapy in prevention of SSI was observed, but different tools to decrease SSIs and SSOs continuously further need our full attention to improve patient outcomes and to lower overall costs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Wouters, Cavallaro, Jensen, East, Jíšová, Jorgensen, López-Cano, Rodrigues-Gonçalves, Stabilini and Berrevoet.)

- Abstract
Background: Ventral hernia repair is one of the most commonly performed surgical procedures worldwide. To reduce the risk of complications, patient prehabilitation has received increasing focus in recent years. To assess prehabilitation measures, this European Hernia Society endorsed project was launched. The aim of this systematic review was to evaluate the current literature on patient prehabilitation prior to ventral hernia repair., Methods: The strategies examined were optimization of renal disease, obesity, nutrition, physical exercise, COPD, diabetes and smoking cessation. For each topic, a separate literature search was conducted, allowing for seven different sub-reviews., Results: A limited amount of well-conducted research studies evaluating prehabilitation prior to ventral hernia surgery was found. The primary findings showed that smoking cessation and weight loss for obese patients led to reduced risks of complications after abdominal wall reconstruction., Conclusion: Prehabilitation prior to ventral hernia repair may be widely used; however, the literature supporting its use is limited. Future studies evaluating the impact of prehabilitation before ventral hernia surgery are warranted., (© 2022.

- Abstract
Background: Abdominal wall hernia repair is one of the most commonly performed surgical procedures worldwide, yet despite this, there remains a lack of high-quality evidence to support best management. The aim of the study was to use a modified Delphi process to determine future research priorities in this field., Methods: Stakeholders were invited by email, using British Hernia Society membership details or Twitter, to submit individual research questions via an online survey. In addition, questions obtained from a patient focus group (PFG) were collated to form Phase I. Two rounds of prioritization by stakeholders (phases II and III) were then completed to determine a final list of research questions. All questions were analyzed on an anonymized basis., Results: A total of 266 questions, 19 from the PFG, were submitted by 113 stakeholders in Phase I. Of these, 64 questions were taken forward for prioritization in Phase II, which was completed by 107 stakeholders. Following Phase II analysis, 97 stakeholders prioritized 36 questions in Phase III. This resulted in a final list of 14 research questions, 3 of which were from the PFG. Stakeholders included patients and healthcare professionals (consultant surgeons, trainee surgeons and other multidisciplinary members) from over 27 countries during the 3 phases., Conclusion: The study has identified 14 key research priorities pertaining to abdominal wall hernia surgery. Uniquely, these priorities have been determined from participation by both healthcare professionals and patients. These priorities should now be addressed by well-designed, high-quality international collaborative research., (© 2021. The Author(s).)

- Abstract
Background: Surgical mesh is widely used not only to treat but also to prevent incisional hernia formation. Despite much effort by material engineers, the 'ideal' mesh mechanically, biologically and surgically easy to use remains elusive. Advances in tissue engineering and nanomedicine have allowed new concepts to be tested with promising results in both small and large animals. Abandoning the concept of a pre-formed mesh completely for a 'pour in liquid mesh' has never been tested before., Materials and Methods: Thirty rabbits underwent midline laparotomy with closure using an absorbable suture and small stitch small bites technique. In addition, their abdominal wall closure was reinforced by a liquid nanofibrous scaffold composed of a fibrin sealant and nanofibres of poly-ε-caprolactone with or without hyaluronic acid or the sealant alone, poured in as an 'onlay' over the closed abdominal wall. The animals were killed at 6 weeks and their abdominal wall was subjected to histological and biomechanical evaluations., Results: All the animals survived the study period with no major complication. Histological evaluation showed an eosinophilic infiltration in all groups and foreign body reaction more pronounced in the groups with nanofibres. Biomechanical testing demonstrated that groups treated with nanofibres developed a scar with higher tensile yield strength., Conclusion: The use of nanofibres in a liquid form applied to the closed abdominal wall is easy to use and improves the biomechanical properties of healing fascia at 6 weeks after midline laparotomy in a rabbit model., (© 2022.

- Abstract
Background: Digital and Social Media (#SoMe) platforms have revolutionized the way information is shared, classified and accessed among medical professionals worldwide. The aim of this study was to review the hashtags used on Twitter by @EuroHerniaS to provide a practical roadmap for easier social media utilization for hernia surgery stakeholders. Methods: The hashtags used in tweets and retweets of the @EuroHerniaS Twitter feed were collated since its foundation in November 2016. Results: The first hashtag used was #HerniaSurgery. Since foundation to July 2021, the @EuroHerniaS Twitter feed has used 90 separate hashtags. The number of new hashtags per year was increasing leading to the development of an online library. The increasing diversity of hernia related hashtags allows for the more detailed posting and searching of hernia related information on the #SoMe platform Twitter. Conclusion: The more detailed use of hashtags on Twitter is to be encouraged. Hernia surgeons can make use of them both when posting and reviewing posts to aid the categorization of posts., Competing Interests: EP is the owner of Pendar Management Consulting and Business Development.

- Abstract
Introduction: Hernias are one of the most common surgical diagnoses, and general surgical operations are performed. The involvement of patients in the decision making can be limited. The aim of this study was to explore the perspectives of patients around their hernia and its management, to aid future planning of hernia services to maximise patient experience, and good outcomes for the patient. Methods: A SurveyMonkey questionnaire was developed by patient advocates with some advice from surgeons. It was promoted on Twitter and Facebook, such as all found "hernia help" groups on these platforms over a 6-week period during the summer of 2020. Demographics, the reasons for seeking a hernia repair, decision making around the choice of surgeon, hospital, mesh type, pre-habilitation, complications, and participation in a hernia registry were collected. Results: In total, 397 questionnaires were completed in the study period. The majority of cases were from English speaking countries. There was a strong request for hernia specialists to perform the surgery, to have detailed knowledge about all aspects of hernia disease and its management, such as no operation and non-mesh options. Chronic pain was the most feared complication. The desire for knowledge about the effect of the hernia and surgery on the sexual function in all age groups was a notable finding. Pre-habilitation and a hernia registry participation were well-supported. Conclusions: Hernia repair is a quality of life surgery. Whether awaiting surgery or having had surgery with a good or bad outcome, patients want information about their condition and treatment, such as the effect on aspects of life, such as sex, and they wish greater involvement in their management decisions. Patients want their surgery by surgeons who can also manage complications of such surgery or recommend further treatment. A large group of "hernia surgery injured" patients feel abandoned by their general surgeon when complications ensue., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 East, Hill, Dames, Blackwell, Laidlaw, Gök, Stabilini and de Beaux.)

- Abstract
Background: An acute inguinal hernia remains a common emergency surgical condition worldwide. While emergency surgery has a major role to play in treatment of acute hernias, not all patients are fit for emergency surgery, nor are facilities for such surgery always available. Taxis is the manual reduction of incarcerated tissues from the hernia sack to its natural compartment, and can help delay the need for surgery from days to months. The aim of this study was to prepare a safe algorithm for performing manual reduction of incarcerated inguinal hernias in adults., Methods: Medline, Scopus, Ovid and Embase were searched for papers related to emergency inguinal hernias and manual reduction. In addition, the British National Formulary and Safe Sedation Practice for Healthcare Procedures: Standards and Guidance were reviewed., Results: A safe technique of manual reduction of an acute inguinal hernia, called GPS (Gentle, Prepared and Safe) Taxis, is described. It should be performed within 24 h from the onset of a painful irreducible lump in groin, and when concomitant symptoms and signs of bowel strangulation are absent. Conscious sedation guidelines should be followed. The most popular drug combination is of intravenous morphine and short-acting benzodiazepine, both titrated carefully for optimal and safe effect. The dose of drugs must be individualised, and the smallest effective dosage should be used to avoid oversedation. Following successful taxis, the patient should undergo a short period of observation. Urgent surgery can be undertaken during the same admission or up to several weeks later., Conclusions: Taxis is a benign/non-invasive method for patients with an acute, non-strangulated inguinal hernias. It likely reduces the risk and complications of anaesthesia and surgery in the emergency settings. GPS Taxis should be considered as first line treatment in the majority of patients presenting with an acute inguinal hernia when existing bowel infarction is unlikely., (© 2021.

- Abstract
Background: Primary and incisional ventral hernia trials collect unstandardized inconsistent data, limiting data interpretation and comparison. This study aimed to create two minimum data sets for primary and incisional ventral hernia interventional trials to standardize data collection and improve trial comparison. To support these data sets, standardized patient-reported outcome measures and trial methodology criteria were created., Methods: To construct these data sets, nominal group technique methodology was employed, involving 15 internationally recognized abdominal wall surgeons and two patient representatives. Initially a maximum data set was created from previous systematic and panellist reviews. Thereafter, three stages of voting took place: stage 1, selection of the number of variables for data set inclusion; stage 2, selection of variables to be included; and stage 3, selection of variable definitions and detection methods. A steering committee interpreted and analysed the data., Results: The maximum data set contained 245 variables. The three stages of voting commenced in October 2019 and had been completed by July 2020. The final primary ventral hernia data set included 32 variables, the incisional ventral hernia data set included 40 variables, the patient-reported outcome measures tool contained 25 questions, and 40 methodological criteria were chosen. The best known variable definitions were selected for accurate variable description. CT was selected as the optimal preoperative descriptor of hernia morphology. Standardized follow-up at 30 days, 1 year, and 5 years was selected., Conclusion: These minimum data sets, patient-reported outcome measures, and methodological criteria have allowed creation of a manual for investigators aiming to undertake primary ventral hernia or incisional ventral hernia interventional trials. Adopting these data sets will improve trial methods and comparisons., (© The Author(s) 2021. Published by Oxford University Press on behalf of BJS Society Ltd. All rights reserved.

- Abstract
Background: Acute IH is a common surgical presentation. Despite new guidelines being published recently, a number of important questions remained unanswered including the role of taxis, as initial non-operative management. This is particularly relevant now due to the possibility of a lack of immediate surgical care as a result of COVID-19. The aim of this review is to assess the role of taxis in the management of emergency inguinal hernias., Methods: A review of the literature was undertaken. Available literature published until March 2019 was obtained and reviewed. 32,021 papers were identified, only 9 were of sufficient value to be used., Results: There was a large discrepancy in the terminology of incarcerated/strangulated used. Taxis can be safely attempted early after the onset of symptoms and is effective in about 70% of patients. The possibility of reduction en-mass should be kept in mind. Definitive surgery to repair the hernia can be delayed by weeks until such time as surgery can be safely arranged., Conclusions: The use of taxis in emergency inguinal hernia is a useful first line of treatment in areas or situations where surgical care is not immediately available, including the COVID-19 pandemic. Emergency surgery remains the mainstay of management in the strangulated hernia setting.

- Abstract
Background: Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management., Methods: The guideline group consisted of surgeons from the European and Americas Hernia Societies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used in formulating the recommendations. The Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists were used to evaluate the quality of full-text papers. A systematic literature search was performed on 1 May 2018 and updated 1 February 2019. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was followed., Results: Literature was limited in quantity and quality. A majority of the recommendations were graded as weak, based on low quality of evidence. In patients with cirrhosis or on dialysis, a preperitoneal mesh repair is suggested. Subsequent pregnancy is a risk factor for recurrence. Repair should be postponed until after the last pregnancy. For patients with a concomitant rectus diastasis or those with a Spigelian or lumbar hernia, no recommendation could be made for treatment strategy owing to lack of evidence., Conclusion: This is the first European and American guideline on the treatment of umbilical and epigastric hernias in patients with special conditions, including Spigelian and lumbar hernias. All recommendations were weak owing to a lack of evidence. Further studies are needed on patients with rectus diastasis, Spigelian and lumbar hernias., (© 2020 The Authors.

- Abstract
Tipping point dynamics are fundamental drivers for sustainable transition pathways of social-ecological systems (SES). Current research predominantly analyzes how crossing tipping points causes regime shifts, however, the analysis of potential transition pathways from these social and ecological tipping points is often overlooked. In this paper, we analyze transition pathways and the potential outcomes that these may lead to via a stylized model of a system composed of interacting agents exploiting resources and, by extension, the overall ecosystem. Interactions between the social and the ecological system are based on a perception-exploitation framework. We show that the presence of tipping points in SES may yield counter-intuitive social-ecological transition pathways. For example, the high perception of an alarming ecological state among agents can provide short-term ecological benefits, but can be less effective in the long term, compared to a low-perception condition. This work also highlights how understanding non-linear interactions is critical for defining suitable transition pathways of any SES.

- Abstract
Background: Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short- and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias., Methods: The guideline group consisted of surgeons from Europe and North America including members from the European Hernia Society and the Americas Hernia Society. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists, and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done on 1 May 2018, and updated on 1 February 2019., Results: Literature reporting specifically on umbilical and epigastric hernias was limited in quantity and quality, resulting in a majority of the recommendations being graded as weak, based on low-quality evidence. The main recommendation was to use mesh for repair of umbilical and epigastric hernias to reduce the recurrence rate. Most umbilical and epigastric hernias may be repaired by an open approach with a preperitoneal flat mesh. A laparoscopic approach may be considered if the hernia defect is large, or if the patient has an increased risk of wound morbidity., Conclusion: This is the first European and American guideline on the treatment of umbilical and epigastric hernias. It is recommended that symptomatic umbilical and epigastric hernias are repaired by an open approach with a preperitoneal flat mesh., (© 2020 BJS Society Ltd Published by John Wiley & Sons Ltd.)

- Abstract
Fascioliasis occurs on all inhabited continents. It is caused by Fasciola hepatica and Fasciola gigantica, trematode parasites with complex life cycles, and primarily affects domestic livestock. Humans become infected after ingestion of contaminated food (typically wild aquatic vegetables) or water. Fascioliasis may be difficult to diagnose as many symptoms are non-specific (e.g. fever, abdominal pain and anorexia). Treatment options are limited, with older effective therapies such as emetine and bithionol no longer used due to safety issues and unavailability, and most common anthelminthics having poor efficacy. Clinical trials conducted over a 25-year period, together with numerous case reports, demonstrated that triclabendazole has high efficacy in the treatment of human fascioliasis in adults and children and in all stages and forms of infection. Triclabendazole was approved for human use in Egypt in 1997 and in France in 2002 and a donation program for the treatment of fascioliasis in endemic countries was subsequently established by the manufacturer and administered by the World Health Organization. Here the published data on triclabendazole in the treatment of human fascioliasis are reviewed, with a focus on more recent data, in light of the 2019 US Food and Drug Administration approval of the drug for use in human infections., (© The Author(s) 2019.

- Abstract
Purpose: Incisional hernia is the most common complication following abdominal surgery. While mesh repair is common, none of the current meshes mimic the physiology of the abdominal wall. This study compares suture only repair with polypropylene mesh and a prototype of a novel implant (poly-epsilon-caprolactone nanofibers) and their influence on the physiology of an abdominal wall in an animal model., Methods: 27 Chinchilla rabbits were divided into six groups based on the type of the implant. Midline abdominal incision was repaired using one of the compared materials with suture alone serving as the control. 6 weeks post-surgery animals were killed and their explanted abdominal wall subjected to biomechanical testing., Results: Both-hysteresis and maximum strength curves showed high elasticity and strength in groups where the novel implant was used. Polypropylene mesh proved as stiff and fragile compared to other groups., Conclusion: Poly-epsilon-caprolactone nanofiber scaffold is able to improve the dynamic properties of healing fascia with no loss of maximum tensile strength when compared to polypropylene mesh in an animal model.
