RESUMO
In 2014 the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias". Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. METHODS: For the development of the original guidelines all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based-Medicine. For the present update all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne) the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. RESULTS: Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques-minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite still insufficient evidence with respect to these new techniques it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. CONCLUSION: Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initially guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

Guidelines are increasingly determining the decision process in day-to-day clinical work. Guidelines describe the current best possible standard in diagnostics and therapy. They should be developed by an international panel of experts, whereby alongside individual experience, above all, the results of comparative studies are decisive. According to the results of high-ranking scientific studies published in peer-reviewed journals, statements and recommendations are formulated, and these are graded strictly according to the criteria of evidence-based medicine. Guidelines can therefore be valuable in helping particularly the young surgeon in his or her day-to-day work to find the best decision for the patient when confronted with a wide and confusing range of options. However, even experienced surgeons benefit because by virtue of a heavy workload and commitment, they often find it difficult to keep up with the ever-increasing published literature. All guidelines require regular updating, usually every 3 years, in line with progress in the field. The current Guidelines focus on technique and perioperative management of laparoscopic ventral hernia repair and constitute the first comprehensive guidelines on this topic. In this issue of Surgical Endoscopy, the first part of the Guidelines is published including sections on basics, indication for surgery, perioperative management, and key points of technique. The next part (Part 2) of the Guidelines will address complications and comparisons between open and laparoscopic techniques. Part 3 will cover mesh technology, hernia prophylaxis, technique-related issues, new technologic developments, lumbar and other unusual hernias, and training/education.

Inguinal hernia operations represent the most frequent operations overall with 300,000 interventions annually in Germany, Austria and Switzerland (DACH region). Despite the announced political willingness and the increasing pressure from the legislator to avoid costly inpatient treatment by carrying out as many outpatient operations as possible, outpatient treatment has so far played a subordinate role in the DACH region. The Boards of the specialist societies the German Hernia Society (DHG), the Surgical Working Group Hernia (CAH of the DHG), the Austrian Hernia Society (ÖHG) and the Swiss Working Group Hernia Surgery (SAHC) make inroads into this problem, describe the initial position and assess the current situation.

INTRODUCTION: Groin hernia repair is performed increasingly more often as an outpatient procedure across the world. However, the rates are extremely different and vary between below 10% and above 90%. The outpatient procedure appears to negatively impact the proportion of laparo-endoscopic repairs. To date, only very few studies have compared inpatient vs outpatient groin hernia repair. METHODS: All outpatient and inpatient primary elective unilateral groin hernia repairs performed between 2010 and 2019 were identified in the Herniamed Registry and their treatment and outcomes compared. RESULTS: The 737 participating hospitals/surgeons performed a total of 342,072 primary elective unilateral groin hernia repairs from 2010 to 2019. The proportion of outpatient repairs was 20.2% in 2013 and 14.3% in 2019. Whereas the proportion of laparo-endoscopic repairs among the inpatient cases was 71.9% in 2019, the last year for which data are available, it was only 34.3%.for outpatient repairs. In outpatient groin hernia repairs, the rates of patients aged ≥ 60 years, with ASA score III and IV and risk factors were highly significantly lower. Given this rigorous patient selection for outpatient groin hernia repair, a more favorable perioperative outcome was achieved. At 1-year follow-up there were no significant differences in the pain and recurrence rates. CONCLUSION: With an appropriate patient selection, outpatient primary elective unilateral groin hernia repair can be performed with acceptable risks and good outcomes. Since to date no studies have compared inpatient vs outpatient groin hernia repair, the impact of a higher rate of outpatient groin hernia repair cannot currently be evaluated.

INTRODUCTION: Rectus abdominis diastasis (RAD) ± concomitant hernia is a complex hernia entity of growing significance in everyday clinical practice. Due to a multitude of described surgical techniques, a so far missing universally accepted classification and hardly existing comparative studies, there are no clear recommendations in guidelines. Therefore, "RAD ± concomitant hernia" will be documented as a separate hernia entity in the Herniamed Registry in the future. For this purpose, an appropriate case report form will be developed on the basis of the existing literature. METHODS: A systematic search of the available literature was performed in March 2021 using Medline, PubMed, Google Scholar, Scopus, Embase, Springer Link, and the Cochrane Library. 93 publications were identified as relevant for this topic. RESULTS: In total 45 different surgical techniques for the repair of RAD ± concomitant hernia were identified in the surgical literature. RAD ± concomitant hernia is predominantly repaired by plastic but also by general surgeons. Classification of RAD ± concomitant hernia is based on a proposal of the German Hernia Society and the International Endohernia Society. Surgical techniques are summarized as groups subject to certain aspects: Techniques with abdominoplasty, open techniques, mini-less-open and endoscopic sublay techniques, mini-less-open and endoscopic subcutaneous/preaponeurotic techniques and laparoscopic techniques. Additional data impacting the outcome are also recorded as is the case for other hernia entities. Despite the complexity of this topic, documentation of RAD ± concomitant hernia has not proved to be any more cumbersome than for any of the other hernia entities when using this classification. CONCLUSION: Using the case report form described here, the complex hernia entity RAD ± concomitant hernia can be recorded in a registry for proper analysis of comparative treatment options.

PURPOSE: In 2009, the European Hernia Society published the EHS Guidelines for the Treatment of Inguinal Hernia in Adult Patients. The Guidelines contain recommendations for the treatment of inguinal hernia from diagnosis till aftercare. The guidelines expired January 1, 2012. To keep them updated, a revision of the guidelines was planned including new level 1 evidence. METHODS: The original Oxford Centre for Evidence-Based Medicine ranking was used. All relevant level 1A and level 1B literature from May 2008 to June 2010 was searched (Medline and Cochrane) by the Working Group members. All chapters were attributed to the two responsible authors in the initial guidelines document. One new chapter on fixation techniques was added. The quality was assessed by the Working Group members during a 2-day meeting and the data were analysed, especially with respect to any change in the level and/or text of any of the conclusions or recommendations of the initial guidelines. In the end, all relevant references published until January 1, 2013 were included. The final text was approved by all Working Group members. RESULTS: For the following topics, the conclusions and/or recommendations have been changed: indications for treatment, treatment of inguinal hernia, day surgery, antibiotic prophylaxis, training, postoperative pain control and chronic pain. The addendum contains all current level 1 conclusions, Grade A recommendations and new Grade B recommendations based on new level 1 evidence (with the changes in bold). CONCLUSIONS: Despite the fact that the Working Group responsible for it tried to represent most kinds of surgeons treating inguinal hernias, such general guidelines inevitably must be fitted to the daily practice of every individual surgeon treating his/her patients. There is no doubt that the future of guideline implementation will strongly depend on the development of easy to use decision support algorithms tailored to the individual patient and on evaluating the effect of guideline implementation on surgical outcome. At the 35th International Congress of the EHS in Gdansk, Poland (May 12-15, 2013), it was decided that the EHS, IEHS and EAES will collaborate from now on with the final goal to publish new joint guidelines, most likely in 2015.

INTRODUCTION: In adult patients, most inguinal hernias are treated by implanting a prosthetic mesh. To prevent mesh dislocation and thus recurrence, different types of fixation have been proposed. In contrast to penetrating fixation known to cause acute chronic pain, adhesive fixation is becoming increasingly popular as it reduces markedly the risk of injury and chronic pain. Apart from the biological sealants (e.g., fibrin glue), surgical adhesives include a group of synthetic glues and genetically engineered protein glues. For example, cyanoacrylate is used in various medical and veterinary indications due to its fast action, excellent bonding strength and low price. OBJECTIVE: The main objective of this paper was to communicate positive results obtained using n-butyl-cyanoacrylate glue to fix prosthetic meshes in over 1,300 TAPP repairs of primary and recurrent inguinal hernias. The secondary objective was to highlight the rationale (e.g., safety) for using non-fibrin based glue in this type of procedure. METHOD: We present the in vitro and in vivo data necessary for the approval of n-butyl cyanoacrylate Histoacryl(®) glue. We use an equivalent glue, Glubran-2(®), to fix prosthetic meshes in 1,336 laparoscopic TAPP repairs. RESULTS: Standardized tests to detect sensitization, irritation, genotoxicity or systemic toxicity demonstrated the safety and biocompatibility of Histoacryl(®), which met all requirements, including those of ISO 10993. Histological long-term studies in rabbits yielded results comparable to routine suture fixations, with full integration of the mesh into the abdominal wall. The clinical results showed the following advantages: fast application of the glue, reduced postoperative pain, 0.0% infection rate, continuously low recurrence rate and shorter hospital stay. No adverse effects and no complaints were recorded. CONCLUSION: The experimental and clinical data demonstrate the safe use and the excellent cost-benefit ratio of n-butyl cyanoacrylate compared with other techniques of mesh fixation.

The European Hernia Society (EHS) is proud to present the EHS Guidelines for the Treatment of Inguinal Hernia in Adult Patients. The Guidelines contain recommendations for the treatment of inguinal hernia from diagnosis till aftercare. They have been developed by a Working Group consisting of expert surgeons with representatives of 14 country members of the EHS. They are evidence-based and, when necessary, a consensus was reached among all members. The Guidelines have been reviewed by a Steering Committee. Before finalisation, feedback from different national hernia societies was obtained. The Appraisal of Guidelines for REsearch and Evaluation (AGREE) instrument was used by the Cochrane Association to validate the Guidelines. The Guidelines can be used to adjust local protocols, for training purposes and quality control. They will be revised in 2012 in order to keep them updated. In between revisions, it is the intention of the Working Group to provide every year, during the EHS annual congress, a short update of new high-level evidence (randomised controlled trials [RCTs] and meta-analyses). Developing guidelines leads to questions that remain to be answered by specific research. Therefore, we provide recommendations for further research that can be performed to raise the level of evidence concerning certain aspects of inguinal hernia treatment. In addition, a short summary, specifically for the general practitioner, is given. In order to increase the practical use of the Guidelines by consultants and residents, more details on the most important surgical techniques, local infiltration anaesthesia and a patient information sheet is provided. The most important challenge now will be the implementation of the Guidelines in daily surgical practice. This remains an important task for the EHS. The establishment of an EHS school for teaching inguinal hernia repair surgical techniques, including tips and tricks from experts to overcome the learning curve (especially in endoscopic repair), will be the next step. Working together on this project was a great learning experience, and it was worthwhile and fun. Cultural differences between members were easily overcome by educating each other, respecting different views and always coming back to the principles of evidence-based medicine. The members of the Working Group would like to thank the EHS board for their support and especially Ethicon for sponsoring the many meetings that were needed to finalise such an ambitious project.
