Incidence of groin hernia repairs in women and parity: a population-based cohort study among women born in Sweden between 1956 and 1983. Hernia 2024:10.1007/s10029-024-03011-1. [PMID: 38520614 DOI: 10.1007/s10029-024-03011-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Accepted: 03/03/2024] [Indexed: 03/25/2024]
Abstract
INTRODUCTION The aim of this study was to evaluate the association between parity and the incidence rate of groin hernia repair in women. METHOD This study was based on two Swedish national registers, the Medical Birth Register (MBR), and the Swedish Hernia Register (SHR). The cohort constituted of women born between 1956 and 1983. Data on vaginal and cesarean deliveries were retrieved from the MBR. The birth and hernia registers were cross matched to identify hernia repairs carried out after deliveries. RESULTS A total of 1,535,379 women were born between 1956 and 1983. Among these, 1,417,237 (92.3%) were registered for at least one birth. The incidence rate for Inguinal Hernia Repair (IHR) and Femoral Hernia Repair (FHR) was 10.7 per 100,000 person-year and 2.6 per 100,000 person-year, respectively. Compared with women registered for one delivery, the incidence rate ratio for IHR was 1.31 (95% Confidence Interval: 1.23-1.40) among women registered for two deliveries, 1.70 (1.58-1.82) among women registered for ≥ 3 deliveries. Additionally, the incidence rate ratios were higher 1.30 (1.14-1.49) and 1.70 (1.49-1.95) for FHR among women with two and ≥ 3 registered deliveries, respectively. CONCLUSION In the present cohort, higher parity was associated with a higher incidence of inguinal as well as FHRs.

Abstract
BACKGROUND Hernia repairs are a commonly performed surgical procedure and the Shouldice Repair of inguinal hernias has been well described before in terms of its outcomes. However, the purpose of this paper was to understand what experts from Shouldice Hospital consider to be the essential steps to the Shouldice Method. METHODS Utilizing a Delphi Methodology, surgeons at Shouldice Hospital who are considered content experts, provided their answers on what is essential to the Shouldice Method. The median, interquartile range, and percent agreement from the responses as well as the Delphi's overall Cronbach's Alpha were determined. All Delphi items were ranked on a five-point Likert scale and consensus was reached when Cronbach's Alpha was ≥ 0.8. The items from the survey that ranked as 5-completely agree or 4-partially agree by ≥ 80% of participants on the five-point Likert scale were included in the final framework. RESULTS The final consensus for the Shouldice Method included 39 items with 7 overarching steps: preoperative preparation of the patient, anesthetic component, incision and nerve identification, treatment of the cremasteric muscles, hernia identification and treatment, reconstruction of the posterior wall, and post-operative management of patients. CONCLUSION The results of this consensus provide a step-by-step approach to the Shouldice Method, as well as information that is timely and can be utilized by surgeons incorporating non-mesh hernia repairs into their practice.

Abstract
BACKGROUND The purpose of this study is to evaluate the diagnostic performance of imaging techniques for the identification of groin hernias based on the type of hernia and to demonstrate the efficacy of an algorithm based on the surgeon and surgical technique. MATERIALS AND METHODS Medical records of 561 patients who were operated on for groin hernia were retrospectively analyzed. A total of 102 patients who had both pelvic computed tomography (CT) and ultrasonography (USG) recordings preoperatively and underwent transabdominal preperitoneal repair were included in the study. RESULTS A contralateral asymptomatic occult groin hernia was detected in 25.5% of all patients. The overall sensitivity of USG and CT on contralateral asymptomatic occult hernia was 42.3% and 65.4%, respectively. The sensitivity of USG according to the contralateral occult hernia type was 66.7%, 35.7%, 33.3%, and 50% for direct, indirect, femoral, and pantaloon hernias, respectively. The sensitivity of CT according to the contralateral occult hernia type was 0%, 57.1%, 100%, and 100% for direct, indirect, femoral, and pantaloon hernias, respectively. CONCLUSIONS The handicap created by the variability in the diagnostic sensitivity of imaging modalities can be overcome with the choice of transabdominal preperitoneal repair in the surgical technique.

Abstract
Abdominopelvic hernias are common clinical entities composed of a wide variety of congenital, traumatic, and iatrogenic etiologies. Any weakness in the body wall may result in hernia of cavity contents with concomitant risks of morbidity and mortality. Presentations may be specific, palpable body wall mass/bulge, or vague, nonspecific pain through bowel obstruction. This document focuses on initial imaging of the adult population with signs of symptoms prompting suspicion of abdominopelvic hernia. Imaging of the abdomen and pelvis to evaluate defects is essential for prompt diagnosis and treatment. Often CT and ultrasound are the first-line modalities to quickly evaluate the abdomen and pelvis, providing for accurate diagnoses and management of patients. MRI protocols may be useful as first-line imaging studies, especially in patients with orthopedic instrumentation. Although often performed, abdominal radiographs and fluorographic procedures may provide indirect evidence of hernias but are usually not indicated for initial diagnosis of hernia. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
Objectives To determine the clinical utility of preoperative ultrasound imaging for predicting an inguinal hernia in need of surgery. In addition, we aimed to identify factors associated with false positive (FP) ultrasound examinations. Methods In this retrospective pilot study, we included all 175 patients who underwent inguinal hernia surgery in our hospital in 2019 and of whom a positive preoperative ultrasound examination of the groin area was available. The positive predictive value (PPV) of the ultrasound examination was determined using inguinal hernia detected during surgery (yes/no) as golden standard. To identify possible predictive factors, we compared the characteristics of patients with a FP ultrasound with patients with a true positive (TP) ultrasound.
Results PPV of ultrasound examinations to identify an inguinal hernia in need of surgery correctly was 90.9% (159/175). The patients with a FP ultrasound examination had a significantly higher body mass index (BMI) than the patients with a TP ultrasound examination (27.6 ± 4.2 vs 25.8 ± 2.3, p = 0.043).
Conclusions With a false positive percentage of 9.1%, there is still room for improvement of preoperative diagnostic imaging. Studies with larger cohorts are necessary to establish prediction models that have the potential to reduce FP ultrasound results.

Abstract
Introduction Symptomatic, clinically occult, radiologically evident inguinal hernias (SCORE-IH) are challenging due to diagnostic uncertainty and a lack of treatment consensus. This study explores current practice among surgeons treating SCORE-IH. Methods A trainee-led research collaborative (STEER) disseminated a validated online survey among UK and international consultants. Collated responses were analysed to determine surgeons’ experience and approach to the management of SCORE-IH. Results A total of 73 responses were received. Overall, 26% of respondents performed more than 100 IH repairs annually. Nearly two-thirds (62%) were unaware of SCORE-IH guidelines. Surgeons chose ultrasonography (31.5%) or ultrasonography with magnetic resonance imaging (24.6%) to manage SCORE-IH. Surgeons managed SCORE-IH conservatively or operatively in 31% and 36% of cases, respectively. Surgeons’ experience and laparoscopic capacity did not correlate with their approach to SCORE-IH management. Conclusions There is heterogeneity in SCORE-IH management, likely due to an absence of adequate guidelines. The results highlight that further SCORE-IH research is needed to achieve consensus.

Abstract
Ultrasound is very effective in performing procedures and assessment of complications in peritoneal dialysis. The ultrasound examination can be applied for preoperative assessment, during the peritoneal catheter placement, for the detection and monitoring of infection, as well as for the evaluation of the catheter malfunction. Despite being not only a cost- and time-saving technique but also a bedside procedure, ultrasonography remains an underrated clinical tool in the field of peritoneal dialysis. This publication wants to explain and reinforce the clinical utility of US in PD and to expand the diagnostic equipment for the clinician.

Abstract
Inguinal hernias are very common. Well-established diagnostic criteria including examination and imaging are available. Ultrasound, herniography, CT, and MR imaging can provide additional diagnostic information when examination alone is not deemed sufficient. However, decision making should not be overly dependent on imaging but must factor in all relevant information. Described here is a case that would have been a missed diagnosis and an example of unconventional documentation that facilitated the patient getting their care.

Abstract
ObjectivesThis study estimated the frequency of ultrasounds ordered for clinically obvious inguinal hernias in patients referred to surgeons and evaluated the clinical value of ultrasonography for this patient population.
MethodsThe present study was a prospective diagnostic and therapeutic impact study conducted in district, rural and tertiary referral hospitals in Sydney, Hawkesbury and Wagga Wagga, Australia. The study included adult patients (≥18 years of age) who had been referred to one of the participating surgeons for an elective inguinal hernia repair. The study determined the proportion of: (1) patients who underwent an inguinal hernia repair for a clinically obvious hernia and also had an ultrasound; (2) ultrasounds ordered by general practitioners (GPs); and (3) these ultrasounds that altered diagnosis and consequent surgical management from the surgeon’s perspective.
ResultsIn all, 144 participants were included in this study. Of these patients, 134 had a clinically apparent inguinal hernia on physical examination, and 63 of 133 patients (47%; 95% confidence interval (CI) 39–56%) underwent an ultrasound (information was missing for one patient). Overall 68 ultrasounds were ordered, with 63 ordered by GPs. Following the ultrasound, surgeons reported that one patient (1%; 95% CI 0–8 patients) had an altered diagnosis, and five patients (8%; 95% CI 3–17 patients) had altered management.
ConclusionThis study found that almost one in two patients referred to a surgeon with a clinically obvious inguinal hernia also underwent a groin ultrasound. These studies represent an unnecessary waste of limited healthcare resources and low-value medical care because they rarely affect the final diagnosis or surgical management.
What is known about the topic?Inguinal hernias are one of the most common presenting complaints to surgeons in Australia. Currently, there are no accepted Australian guidelines for the diagnosis of inguinal hernias. Ultrasound investigation has been shown to aid diagnosis when there is uncertainty after physical examination. There is increasing concern regarding low-value medical care that contributes to a significant waste of healthcare resources within Australia. The use of ultrasounds for the diagnosis of clinically apparent inguinal hernias is a potential area of concern.
What does this paper add?This paper is the first to estimate the frequency of ultrasounds being ordered for clinically apparent inguinal hernias. The study shows that approximately one in two patients who present to surgeons with a clinically obvious inguinal hernia have an ultrasound. GPs were the major referral source for these ultrasounds. Finally, these ultrasounds rarely altered final diagnosis or management for patients who presented to surgeons for definitive management.
What are the implications for practitioners?This study confirms that ultrasounds for clinically obvious inguinal hernias represent low-value medical care. Based on the results of this study, it is estimated that the cost to Medicare for unnecessary ultrasounds is approximately A$2.5 million per annum. Although it is beyond the scope of the present study to comment on the reasons for the apparent overinvestigation of ultrasounds for inguinal hernias, the findings suggest that clinical guidelines may help address this problem.

Abstract
BACKGROUND The treatment of inguinoscrotal hernias (ISH) represents one of the most challenging areas in surgical pathology. Although these hernias could be repaired through a minimally invasive approach, open repair is still considered to be the technique of choice for most surgeons. The purpose of this study is to evaluate our new combined [open+transabdominal preperitoneal (TAPP)/total preperitoneal (TEP)] method of ISH repair. PATIENTS AND METHODS The authors reviewed the charts of 124 patients with ISH who underwent hernia repair in different modifications: open, TAPP, TEP, and new combined method with a minimal follow-up of 3 months. RESULTS New combined (open+TAPP/TEP) method repair was successful in all 38 patients. Average case duration was 68.8 minutes (62 to 106 min). No recurrence was observed for the 13 months follow-up. Two patients had intraoperative serosal bowel injury, 1 patient developed postoperative seroma, and 2 patients developed several pain. CONCLUSIONS Combined (open+TAPP/TEP) method for ISH repair allows to minimize surgical trauma and reduce both the procedure time and the postoperative length of stay. Implementation of this method results in statistically significantly fewer wound-related postoperative complications compared with traditional methods.

Abstract
PURPOSE The aim of the study was to determine which diagnostic modality [Computerized Tomography (CT), Magnetic Resonance Imaging (MRI), or ultrasound (US)] is more precise in terms of sensitivity and specificity in diagnosing inguinal hernia and sub-type of inguinal hernia (direct or indirect). METHODS This systematic review was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and a search for relevant articles was undertaken in PubMed, Embase, and the Cochrane Library. Inclusion criteria were original studies that preoperatively diagnosed patients suspected of inguinal hernia by either CT, MRI, or US and compared diagnostic findings with operative findings or definitive follow-up. The main outcomes were the diagnostic certainty of inguinal hernia and type of hernia by sensitivity and specificity. All eligible studies were searched in the Retraction Watch database to ensure that all included studies were suitable for inclusion. RESULTS Bubble charts depicting the size of each patient cohort and percentual range for both sensitivity and specificity showed that US was better than CT and MRI in diagnosing inguinal hernia. Bubble charts for US and CT depicted high values within the studies that reported sensitivity and specificity in diagnosing type of hernia. CONCLUSIONS We found that US had the highest sensitivity and specificity. However, it must be taken into consideration that performance is highly dependent on the operator's level of expertise. Based on this systematic review, ultrasound may be the preferred imaging modality when physical examination is inconclusive, given that local expertise in performing US examination for hernia disease is adequate.

Abstract
INTRODUCTION Synthetic non-resorbable mesh is almost standard in hernia surgery. However, several studies have showed negative effects of permanent implants such as chronic inflammation and complications involving different organs bordering the mesh. Such complications can raise the risk of chronic post-operative pain (CPP). Recently promising results regarding CPP have been published in patients with Lateral Inguinal Hernia (LIH) using a slowly resorbable mesh in Lichtenstein technique. For this reason the aim of the present study was to find the effect of a slowly resorbable implant on the long-term rate of hernia recurrence and chronic post-operative pain in patients with LIH repaired with TEP procedure. METHODS Prospective pilot study of TEP repair using TIGR® Matrix Surgical Mesh in 35 primary LIH. At 3-year follow-up the Visual Analogue Scale (VAS) and the Inguinal Pain Questionnaire were employed to assess pain. Recurrence was determined by ultrasound and clinical examination. RESULTS All patients completed the pain questionnaires but one patient did not attend the planned clinical examination for the 3-year follow-up. No patients had CPP, as defined in the World Guidelines for Groin Hernia Management. Almost all patients had lower VAS score in any activity 3 years following surgery in comparison to the preoperative period. Three patients (8.8%) suffered symptomatic recurrence during the 3-year follow-up. CONCLUSION TEP repair in patients with LIH using a synthetic long-term resorbable mesh was found to be encouraging respecting chronic post-operative pain at 3-year follow-up but at the cost of an increased risk of recurrence.

Abstract
BACKGROUND General surgeons frequently see patients with groin lumps and pain. However, in the absence of a lump, an ultrasound scan identified groin hernia is a diagnostic and management challenge. Some surgeons recommend inguinal hernia surgery while others do not. The outcome of non-operative management is uncertain. METHODS This study represents a minimum 3-year follow-up of all non-operatively managed patients seen in general surgical outpatient clinic over a 12-month period. To be included, patients needed to meet all four criteria: groin pain, no clinical hernia, groin hernia identified on ultrasound scan requested by the general practitioner and non-operative management. Patients were interviewed via a standardised telephone survey. Primary outcome measure was groin pain which was assessed with the Sheffield Pain score. RESULTS From July 2014 to June 2015, 67 patients met the inclusion criteria. 42 participated (37 men and 5 women). Two-thirds were pain free (68%). Only 2 patients underwent hernia surgery. Women were more likely to describe developing a lump (60% vs 14%; p = 0.013), to see a surgeon (40% vs 8%; p = 0.039) and undergo hernia surgery (20% vs 3% p = 0.088). CONCLUSION At least in the medium term, non-operative management of men who present with groin pain (with an ultrasound scan reporting a hernia but no lump) is reasonable.

Abstract
OBJECTIVES This study aims to compare ultrasonography for ventral hernias with surgical findings and establish its accuracy in equivocal cases. Comparison is also made against groin hernia ultrasound scanning, which has a positive predictive value ranging from 71-100%. METHODS A retrospective review of all patients who underwent an ultrasound scan between June 2011 and June 2015 was performed. The word "hernia" in the referral information was the sole inclusioncriterion. Patients who were found to have a clinically evident ventral hernia, unrelated hernia in aseparate location or had a known hernia were excluded. Thus, only patients with a clinically suspected ventral hernia and equivocal clinical assessment were included. These patients were followed up for at least 12 months and subsequent operation notes, if any, were also analysed. RESULTS 348 scans were included (F = 198, M = 150, F:M ratio = 1.32:1). The mean age was 53.4 years (range = 16-97 years). 101 scans were positive for hernias (29.0%), 190 were negative (54.3%), and 57 had other findings (e.g. seroma, lipoma; 16.3%). 54 patients were taken to surgery (15.5%), including 5 who were found to be negative on ultrasound. Of these, 45 were truepositives, 4 true-negatives, 4 false-negatives, and 1 false-positive, giving a sensitivity of 91.8% and positive predictive value of 97.8%. CONCLUSION This study confirms that ultrasound scans are effective in the diagnosis of equivocal ventral hernias. Advances in knowledge: The accuracy of ultrasound scanning specifically for ventral hernias is quantified, and are comparable to that of groin hernias.

Abstract
BACKGROUND Increasingly, abdominal wall hernias are being diagnosed incidentally through radiographic imaging. Such hernias are referred to as occult. However, the clinical significance of occult hernias is unknown. The objective of this study is to determine the prevalence of occult hernias and to assess the abdominal wall quality of life (AW-QOL) among patients with occult hernias. MATERIALS AND METHODS A blinded, observational, cross-sectional study, October-December 2016, of patients presenting to single academic institution's general surgery clinics was performed. Inclusion criteria included all patients with a computed tomography scan of the abdomen or pelvis within the last year with no intervening abdominal or pelvic surgery. Patients were administered a validated AW-QOL survey and underwent a standardized clinical examination. Computed tomography scans were reviewed. Primary outcomes were prevalence and AW-QOL measured by the modified Activities Assessment Scale. AW-QOL of patients with no hernias was compared to that of those with occult hernias and clinically apparent hernias using Mann-Whitney U test. RESULTS A total of 250 patients were enrolled of whom 97 (38.8%) had a hernia noted on clinical examination and 132 (52.8%) had a hernia noted on radiographic imaging. The prevalence of occult hernias was 38 (15.2%). Patients with no hernia had a median (interquartile range) AW-QOL of 82.5 (55.0-95.3), patients with clinically apparent hernias had AW-QOL of 47.7 (31.2-81.6; P < 0.001), and patients with occult hernias had AW-QOL of 72.4 (38.5-97.2; P = 0.36). CONCLUSIONS Both clinically apparent and occult hernias are prevalent. However, only patients with clinically apparent hernias had differences in AW-QOL when compared to patients with no hernias. Prospective trials are needed to assess the outcomes of patients with occult hernias managed with and without surgical repair.

Abstract
Background Current recommendations for hernia treatment suggest applying techniques aimed at reducing postoperative pain in patients experiencing intense preoperative pain. However, there is still no reliable stratification method of preoperative pain, its circumstances, intensity and frequency, and the current assessments of hernia symptoms are performed by means of a subjective evaluation. The aim of this work is to discuss preoperative pain before hernia repair and determine its nature depending on the type and length of hernia persistence and the patient’s age. Materials and methods The data from 1647 patients before inguinal hernia repairs (2010–2017) were registered prospectively in the National Hernia Repair Register (demographic data, pain score and influence on everyday activities). Results The most common symptom upon admission was pain (949 patients at rest; 57.6% and 1561 at physical activity; 94.8%). A significant influence of hernia persistence on the pain occurrence and intensity was not observed between patients with hernia < 12-months (60.8%;VAS5.0) and > 5-years (58.3%;VAS5.4) (p = 0.068). The occurrence and intensity of pain was significantly higher patients < 40-years (63.7%;VAS5.4) than patients > 60-years (54.3%;VAS4.8) (p = 0.008). Conclusions While pain at rest is not a significant problem, undertaking physical activities may intensify pain and increase the number of patients suffering from it. Preoperative assessment of pain may help determine the group of younger patients who could benefit the most from inguinal hernia repair. New indications for prompter admission for treatment should be planned in future studies of patients showing pain at rest for possible prevention of postoperative neuropathy.

Abstract
INTRODUCTION Worldwide, 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. METHODS An 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. The 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 should be tailored to the surgeon's expertise, patient- and hernia-related characteristics and local/national resources. Furthermore, patient health-related, life style and social factors should all influence the shared decision-making process leading up to hernia management. Mesh repair is recommended as first choice, either by an open procedure or a laparo-endoscopic repair technique. One standard repair technique for all groin hernias does not exist. It is recommended that surgeons/surgical services provide both anterior and posterior approach options. Lichtenstein and laparo-endoscopic repair are best evaluated. Many other techniques need further evaluation. Provided that resources and expertise are available, laparo-endoscopic techniques have faster recovery times, lower chronic pain risk and are cost effective. There is discussion concerning laparo-endoscopic management of potential bilateral hernias (occult hernia issue). After patient consent, during TAPP, the contra-lateral side should be inspected. This is not suggested during unilateral TEP repair. After appropriate discussions with patients concerning results tissue repair (first choice is the Shouldice technique) can be offered. Day surgery is recommended for the majority of groin hernia repair provided aftercare is organized. Surgeons should be aware of the intrinsic characteristics of the meshes they use. Use of so-called low-weight mesh may have slight short-term benefits like reduced postoperative pain and shorter convalescence, but are not associated with better longer-term outcomes like recurrence and chronic pain. Mesh selection on weight alone is not recommended. The incidence of erosion seems higher with plug versus flat mesh. It is suggested not to use plug repair techniques. The use of other implants to replace the standard flat mesh in the Lichtenstein technique is currently not recommended. In almost all cases, mesh fixation in TEP is unnecessary. In both TEP and TAPP it is recommended to fix mesh in M3 hernias (large medial) to reduce recurrence risk. Antibiotic prophylaxis in average-risk patients in low-risk environments is not recommended in open surgery. In laparo-endoscopic repair it is never recommended. Local anesthesia in open repair has many advantages, and its use is recommended provided the surgeon is experienced in this technique. General anesthesia is suggested over regional in patients aged 65 and older as it might be associated with fewer complications like myocardial infarction, pneumonia and thromboembolism. Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair. Patients are recommended to resume normal activities without restrictions as soon as they feel comfortable. Provided expertise is available, it is suggested that women with groin hernias undergo laparo-endoscopic repair in order to decrease the risk of chronic pain and avoid missing a femoral hernia. Watchful waiting is suggested in pregnant women as groin swelling most often consists of self-limited round ligament varicosities. Timely mesh repair by a laparo-endoscopic approach is suggested for femoral hernias provided expertise is available. All complications of groin hernia management are discussed in an extensive chapter on the topic. Overall, the incidence of clinically significant chronic pain is in the 10-12% range, decreasing over time. Debilitating chronic pain affecting normal daily activities or work ranges from 0.5 to 6%. Chronic postoperative inguinal pain (CPIP) is defined as bothersome moderate pain impacting daily activities lasting at least 3 months postoperatively and decreasing over time. CPIP risk factors include: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia and open repair. For CPIP the focus should be on nerve recognition in open surgery and, in selected cases, prophylactic pragmatic nerve resection (planned resection is not suggested). It is suggested that CPIP management be performed by multi-disciplinary teams. It is also suggested that CPIP be managed by a combination of pharmacological and interventional measures and, if this is unsuccessful, followed by, in selected cases (triple) neurectomy and (in selected cases) mesh removal. For recurrent hernia after anterior repair, posterior repair is recommended. If recurrence occurs after a posterior repair, an anterior repair is recommended. After a failed anterior and posterior approach, management by a specialist hernia surgeon is recommended. Risk factors for hernia incarceration/strangulation include: female gender, femoral hernia and a history of hospitalization related to groin hernia. It is suggested that treatment of emergencies be tailored according to patient- and hernia-related factors, local expertise and resources. Learning curves vary between different techniques. Probably about 100 supervised laparo-endoscopic repairs are needed to achieve the same results as open mesh surgery like Lichtenstein. It is suggested that case load per surgeon is more important than center volume. It is recommended that minimum requirements be developed to certify individuals as expert hernia surgeon. The same is true for the designation "Hernia Center". From a cost-effectiveness perspective, day-case laparoscopic IH repair with minimal use of disposables is recommended. The development and implementation of national groin hernia registries in every country (or region, in the case of small country populations) is suggested. They should include patient follow-up data and account for local healthcare structures. A dissemination and implementation plan of the guidelines will be developed by global (HerniaSurge), regional (international societies) and local (national chapters) initiatives through internet websites, social media and smartphone apps. An overarching plan to improve access to safe IH surgery in low-resource settings (LRSs) is needed. It is suggested that this plan contains simple guidelines and a sustainability strategy, independent of international aid. It is suggested that in LRSs the focus be on performing high-volume Lichtenstein repair under local anesthesia using low-cost mesh. Three chapters discuss future research, guidelines for general practitioners and guidelines for patients. CONCLUSIONS The HerniaSurge Group has developed these extensive and inclusive guidelines for the management of adult groin hernia patients. It is hoped that they will lead to better outcomes for groin hernia patients wherever they live. More knowledge, better training, national audit and specialization in groin hernia management will standardize care for these patients, lead to more effective and efficient healthcare and provide direction for future research.

Abstract
PURPOSE Although clinical examination is the gold standard for the diagnosis of groin hernia, imaging procedures can improve the detection of femoral hernias, incipient hernias, and less-common types of hernias (e.g., an obturator hernia). The aim of this study is to evaluate the sensitivity and specificity of dynamic inguinal ultrasound (DIUS). MATERIALS AND METHODS Between July 2010 and June 2015, 4951 clinical and ultrasound examinations of the groin area were conducted at the Hanse-Hernienzentrum in Hamburg, Germany. The ultrasonographic findings were prospectively evaluated to determine the number of inguinal and femoral hernia diagnoses that were ultrasonically confirmed and also to consider cases in which clinical examination overlooked these diagnoses. The results were compared with the intraoperative findings. RESULTS The results show that standardized ultrasound examination of the groin area with high-frequency, small-part linear transducers also serves to accurately display femoral and small or occult groin hernias. The high-level specificity (0.9980) and sensitivity (0.9758) are proof of the procedure's quality. CONCLUSIONS To ensure high-quality hernia treatment, regular use of standardized ultrasound examinations is recommended.

Abstract
BACKGROUND To evaluate the accuracy of ultrasound (US) in diagnosing the the presence and type of groin hernia. METHODS We retrospectively studied the results of 172 US examinations of the groin in 151 patients (101 men and 50 women; mean age, 59 years) who had undergone US examination for suspected groin hernia. In total, 119 of the groin hernias had been diagnosed on US, and 108 (91%) had required subsequent surgery. All patients who had had positive results for hernia on US and did not undergo surgery (n = 11) and most of the patients whose US results had been negative for hernia (n = 48) underwent limited MRI or CT scanning. We determined the sensitivity, specificity, and accuracy of US in diagnosing the presence and type of groin hernia. To identify any change in the accuracy of US over time at our institution, we compared the sensitivity, specificity, and accuracy of its use from January 2002 through December 2010 (n = 54 groins) with those from January 2011 through December 2012 (n = 118 groins). RESULTS The overall rates of sensitivity and specificity of US for diagnosing the presence of groin hernia were 96% and 96%. These rates reflect improvements from 92% and 88% prior to 2011 to 98% and 100% beginning in 2011. In addition, the overall accuracy of US for diagnosing the type of groin hernia was 96%. This also improved over time at our center from 91% prior to 2011 to 98% beginning in 2011. CONCLUSIONS US is highly accurate at diagnosing the presence and type of groin hernia.

Abstract
OBJECTIVES This study explored the diagnostic values of an automated breast volume scanner (ABVS) for abdominal external hernias. METHODS Conventional sonograms and ABVS images from 128 abdominal external hernias in 104 patients (98 male and 6 female; age range, 41-79 years; mean age ± SD, 68.0 ± 14.6 years) were analyzed. The results were identified by surgical outcomes. The hernia type, hernial ring position, hernial sac size, hernia content, and hernia structure were evaluated by both sonographic modalities. RESULTS The sensitivity and accuracy differences between the ABVS and conventional sonography for diagnosis of abdominal hernias and hernia size measurements were compared. The hernia types, as confirmed by surgery, included 45 indirect inguinal hernias (30 reducible and 15 irreducible), 12 reducible direct inguinal hernias, 5 femoral hernias, 62 incisional hernias (42 isolated and 20 multiple), and 4 umbilical hernias. The sensitivity of the ABVS was higher than that of conventional sonography for incisional hernias (P < .01), whereas there were no statistical differences in sensitivity for other types of hernias. The ABVS hernial sac number detection rate for both isolated and multiple incisional hernias was significantly higher compared with that of conventional sonography (both P < .01). The ABVS measurements correlated well with surgical results (length, P = .47; width, P = .31). CONCLUSIONS Automated breast volume scanner images have the outstanding advantage of displaying the entire scope of the internal structure and the relationship with adjacent tissues of abdominal hernias. Therefore, an ABVS has good application prospects for diagnosis of abdominal external hernias and merits further research.

Abstract
Inguinal hernia is the most common surgical repair performed in England with more than 73,000 cases in 2007. The majority of inguinal hernias are diagnosed clinically, but ultrasound is fast becoming the imaging modality of choice for diagnosing occult hernia, due to its non-invasive nature and lack of radiation. At the Norfolk and Norwich University Hospitals NHS Foundation Trust, ultrasound of the groin was performed only by radiologists, but recently sonographers have also begun examining patients for inguinal hernia. This study investigates the accuracy of ultrasound diagnosis of hernia and compares the performances of radiologists and sonographers over a nine-month period involving 124 patients. Our results indicate that both professional groups have a high detection rate and that there is no significant difference in accuracy. An incidental finding was that many general practitioner referrals diagnosed with an inguinal hernia did not proceed to surgery. Since many ultrasound departments are experiencing demand versus capacity issues, it may be that further investigation into the value of diagnosis when surgery is unlikely is warranted.

Abstract
Groin hernias are common conditions, and there is a need for accurate imaging when the clinical diagnosis is not clear. A meta-analysis was undertaken to investigate the diagnostic accuracy of sonography in the diagnosis of inguinal hernias. After review of literature searches, 9 original articles were included. Data were pooled and statistically analyzed. In the studies included, sensitivity ranged from 92.7% to 100%; specificity ranged from 22.2% to 100%; the positive predictive value ranged from 83.3 to 100%; and the negative predictive value ranged from 40 to 100%. Sonography has overall sensitivity of 96.6 %, specificity of 84.8%, and a positive predictive value of 92.6%. In cases of diagnostic uncertainty, sonography offers value as an initial imaging modality. It has advantages over other radiologic methods, as it is inexpensive and has minimal complications. When the clinical diagnosis of an inguinal hernia is uncertain, sonographic findings should be interpreted in conjunction with clinical judgment, as its diagnostic accuracy is reduced in the absence of any clinically palpable hernia.

Abstract
Individually, inguinal hernias and acute appendicitis are common, but the combination of the two, acute appendicitis within an inguinal hernia or Amyand hernia (AH), is rare. The overwhelming majority of AH cases are in males and discovered during surgery. To date, only three case reports in the literature of this pathology have been diagnosed with sonography. This is a report of an AH diagnosed in a woman with sonography.
