IntroductionWorldwide, more than 20 million patients undergo groin hernia repair annually. The many different approaches, treatment indications and a significant array of techniques for groin hernia repair warrant guidelines to standardize care, minimize complications, and improve results. The main goal of these guidelines is to improve patient outcomes, specifically to decrease recurrence rates and reduce chronic pain, the most frequent problems following groin hernia repair. They have been endorsed by all five continental hernia societies, the International Endo Hernia Society and the European Association for Endoscopic Surgery.MethodsAn expert group of international surgeons (the HerniaSurge Group) and one anesthesiologist pain expert was formed. The group consisted of members from all continents with specific experience in hernia-related research. Care was taken to include surgeons who perform different types of repair and had preferably performed research on groin hernia surgery. During the Group’s first meeting, evidence-based medicine (EBM) training occurred and 166 key questions (KQ) were formulated. EBM rules were followed in complete literature searches (including a complete search by The Dutch Cochrane database) to January 1, 2015 and to July 1, 2015 for level 1 publications. The articles were scored by teams of two or three according to Oxford, SIGN and Grade methodologies. During five 2-day meetings, results were discussed with the working group members leading to 136 statements and 88 recommendations. Recommendations were graded as “strong” (recommendations) or “weak” (suggestions) and by consensus in some cases upgraded. In the Results and summary section below, the term “should” refers to a recommendation. The AGREE II instrument was used to validate the guidelines. An external review was performed by three international experts. They recommended the guidelines with high scores.Results and summaryThe risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia. These should be considered when treating IH patients. IH diagnosis can be confirmed by physical examination alone in the vast majority of patients with appropriate signs and symptoms. Rarely, ultrasound is necessary. Less commonly still, a dynamic MRI or CT scan or herniography may be needed. The EHS classification system is suggested to stratify IH patients for tailored treatment, research and audit. Symptomatic groin hernias should be treated surgically. Asymptomatic or minimally symptomatic male IH patients may be managed with “watchful waiting” since their risk of hernia-related emergencies is low. The majority of these individuals will eventually require surgery; therefore, surgical risks and the watchful waiting strategy should be discussed with patients. Surgical treatment s...
Introduction The Accreditation and Certification of Hernia Centers and Surgeons (ACCESS) Group of the European Hernia Society (EHS) recognizes that there is a growing need to train specialist abdominal wall surgeons. The most important and relevant argument for this proposal and statement is the growing acceptance of the increasing complexity of abdominal wall surgery due to newer techniques, more challenging cases and the required 'tailored' approach to such surgery. There is now also an increasing public awareness with social media, whereby optimal treatment results are demanded by patients. However, to date the complexity of abdominal wall surgery has not been properly or adequately defined in the current literature. Methods A systematic search of the available literature was performed in May 2019 using Medline, PubMed, Scopus, Embase, Springer Link, and the Cochrane Library, with 75 publications identified as relevant. In addition, an analysis of data from the Herniamed Hernia Registry was performed. The percentage of patients with hernia-or patient-related characteristics which unfavorably impacted the outcome of inguinal and incisional hernia repair was also calculated. Results All present guidelines for abdominal wall surgery recommend the utilization of a 'tailored' approach. This relies on the prerequisite that any surgical technique used has already been mastered, as well as the recognized learning curves for each of the several techniques that can be used for both inguinal hernia (Lichtenstein, TEP, TAPP, Shouldice) and incisional hernia repairs (laparoscopic IPOM, open sublay, open IPOM, open onlay, open or endoscopic component separation technique).Other hernia-and patient-related characteristics that have recognized complexity include emergency surgery, obesity, recurrent hernias, bilateral inguinal hernias, groin hernia in women, scrotal hernias, large defects, high ASA scores, > 80 years of age, increased medical risk factors and previous lower abdominal surgery. The proportion of patients with at least one of these characteristics in the Herniamed Hernia Registry in the case of both inguinal and incisional hernia is noted to be relatively high at around 70%. In general surgery training approximately 50-100 hernia repairs on average are performed by each trainee, with around only 25 laparo-endoscopic procedures. Conclusion A tailored approach is now employed and seen more so in hernia surgery and this fact is referred to and highlighted in the contemporaneous hernia guidelines published to date. In addition, with the increasing complexity of abdominal wall surgery, the number of procedures actually performed by trainees is no longer considered adequate to overcome any recognized learning curve. Therefore, to supplement general surgery training young surgeons should be offered a clinical fellowship to obtain an additional qualification as an abdominal wall surgeon and thus improve their clinical and operative experience under supervision in this field. Practicing general surgeons with a special int...
Introduction There is a need for hernia centers and specialist hernia surgeons because of the increasing complexity of hernia surgery procedures due to new techniques, more difficult cases and a tailored approach with an increasing public awareness demanding optimal treatment results. Therefore, the requirements for accredited/certified hernia centers and specialist hernia surgeons should be formulated by the international and national hernia societies, while taking account of the respective health care systems. Methods The European Hernia Society (EHS) has appointed a working group composed of 18 hernia experts from all regions of Europe (ACCESS Group—Hernia Accreditation and Certification of Centers and Surgeons—Working Group) to formulate scientifically based requirements for hernia centers and specialist hernia surgeons while taking into consideration different health care systems. A consensus was reached on the key questions by means of a meeting, a telephone conference and the exchange of contributions. The requirements formulated below were deemed implementable by all participating hernia experts in their respective countries. Results The ACCESS Group suggests for an adequately equipped hernia center the following requirements: (a) to be accredited/certified by a national or international hernia society, (b) to perform a higher case volume in all types of hernia surgery compared to an average general surgery department in their country, (c) to be staffed by experienced hernia surgeons who are beyond the learning curve for all types of hernia surgery recommended in the guidelines and are responsible for education and training of hernia surgery in their department, (d) to treat hernia patients according to the current guidelines and scientific recommendations, (e) to document each case prospectively in a registry or quality assurance database (f) to perform follow-up for comparison of their own results with benchmark data for continuous improvement of their treatment results and ensuring contribution to research in hernia treatment. To become a specialist hernia surgeon, the ACCESS Group suggests a general surgeon to master the learning curve of all open and laparo-endoscopic hernia procedures recommended in the guidelines, perform a high caseload and additionally to implement and fulfill the other requirements for a hernia center. Conclusion Based on the above requirements formulated by the European Hernia Society for accredited/certified hernia centers and hernia specialist surgeons, the national and international hernia societies can now develop their own programs, while taking account of their specific health care systems.
Background The literature dealing with abdominal wall surgery is often flawed due to lack of adherence to accepted reporting standards and statistical methodology. Materials and methods The EuraHS Working Group (European Registry of Abdominal Wall Hernias) organised a consensus meeting of surgical experts and researchers with an interest in abdominal wall surgery, including a statistician, the editors of the journal Hernia and scientists experienced in meta-analysis. Detailed discussions took place to identify the basic ground rules necessary to improve the quality of research reports related to abdominal wall reconstruction. Hernia (2013) 17:423-433 DOI 10.1007/s10029-013-1108 Results A list of recommendations was formulated including more general issues on the scientific methodology and statistical approach. Standards and statements are available, each depending on the type of study that is being reported: the CONSORT statement for the Randomised Controlled Trials, the TREND statement for non randomised interventional studies, the STROBE statement for observational studies, the STARLITE statement for literature searches, the MOOSE statement for metaanalyses of observational studies and the PRISMA statement for systematic reviews and meta-analyses. A number of recommendations were made, including the use of previously published standard definitions and classifications relating to hernia variables and treatment; the use of the validated Clavien-Dindo classification to report complications in hernia surgery; the use of ''time-to-event analysis'' to report data on ''freedom-of-recurrence'' rather than the use of recurrence rates, because it is more sensitive and accounts for the patients that are lost to follow-up compared with other reporting methods. Conclusion A set of recommendations for reporting outcome results of abdominal wall surgery was formulated as guidance for researchers. It is anticipated that the use of these recommendations will increase the quality and meaning of abdominal wall surgery research.
IntroductionThe aim of the international CORE project was to explore the databases of the existing hernia registries and compare them in content and outcome variables.MethodsThe CORE project was initiated with representatives from all established hernia registries (Danish Hernia Database, Swedish Hernia Registry, Herniamed, EuraHS, Club Hernie, EVEREG, AHSQC) in March 2015 in Berlin. The following categories were used to compare the registries: initiation and funding, data collection and use for certification of hernia centers, patient data and data protection, operative data, registration of complications and follow-up data.ResultsThe Danish Hernia Database is the only one to qualify as a genuine national registry where participation is compulsory for entry of all procedures by all surgeons performing a hernia operation. All other registries have to be considered as voluntary and completeness of data depends upon the participating hospitals and surgeons. Only the Danish Hernia Database and the Swedish Hernia Registry are publicly funded. All other registries are reliant on financial support from the medical technology industry. As an incentive for voluntary participation in a hernia registry, hospitals or surgeons are issued a certificate confirming that they are taking part in a quality assurance study for hernia surgery. Due to data protection and privacy regulations, most registries are obliged or have chosen to enter their patient data anonymously or coded. The Danish Hernia Database and Swedish Hernia Registry utilize a national personal patient code. In the Herniamed Registry, patient data are saved in a coded and anonymous format after obtaining the patient’s informed consent.ConclusionDespite the differences in the way data are collected for each of the listed hernia registries, the data are indispensable in clinical research.
