Yang G, Tung KLM, Tumtavitikul S, Li MKW. A new groin hernia classification with clinical relevance. Hernia 2024:10.1007/s10029-024-03000-4. [PMID: 38662243 DOI: 10.1007/s10029-024-03000-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 02/20/2024] [Indexed: 04/26/2024]
Abstract
INTRODUCTION Groin hernia is one of the most commonly managed surgical diseases around the world. The typical question asked by patients is "Does my hernia require urgent surgery?". The currently available classifications are insufficient to stratify patients into different groups. We propose a new classification that incorporates diverse clinical elements together with anatomical and other vital information, which allows us to stratify patients into different groups. METHOD A task force was formed by the Hong Kong Hernia Society, working with international expert hernia surgeons. The framework of the classification system was formulated. Clinical elements that are important in groin disease stratification were identified. A comprehensive literature review was conducted using PubMed. Those which dictate the severity of the disease were selected and compiled to form the new proposed classification. Application of this classification model to a single hernia surgeon's registry in The Hong Kong Adventist Hospital Hernia Centre was done for initial evaluation. RESULT This new classification incorporates important clinical characteristics forming a total of nine grades of differentiation, together with the anatomical details and special information. This comprehensive system allows the stratification of patients into different groups based on disease severity. It also enables more accurate data collection for future audits, comparisons of disease progression over time, and the effect of different management strategies for different-stage patients. CONCLUSION This is the first classification system which incorporates essential clinical parameters, which allows the stratification of groin hernia into different stages. Further studies and validation should be performed to evaluate the usefulness and value of this classification in groin hernia management.

Female sex and ipsilateral reoperation risk following mesh-based inguinal hernia repair: a cohort study including 131,626 repairs in adults from an integrated healthcare system over a 10-year period. Hernia 2024; 28:25-31. [PMID: 37682377 DOI: 10.1007/s10029-023-02878-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 08/29/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE We sought to compare females and males for the risk of reoperation following different inguinal hernia repair approaches (open, laparoscopic, and robotic). METHODS We conducted a retrospective cohort study including all patients aged ≥ 18 who underwent first inguinal hernia repair with mesh within a US integrated healthcare system (2010-2020). Data were obtained from the system's integrated electronic health record. Multiple Cox proportional-hazards regression was used to evaluate the association between sex and risk for ipsilateral reoperation during follow-up. Analysis was stratified by surgical approach (open, laparoscopic, and robotic). RESULTS The study cohort was comprised of 110,805 patients who underwent 131,626 inguinal hernia repairs with mesh, 10,079 (7.7%) repairs were in females. After adjustment for confounders, females had a higher risk of reoperation than males following open groin hernia repair (hazard ratio [HR] = 1.98, 95% CI 1.74-2.25), but a lower reoperation risk following laparoscopic repair (HR = 0.70, 95% CI 0.51-0.97). The crude 5-year cumulative reoperation probability following robotic repair was 2.8% in males and no reoperations were observed for females. Of females who had a reoperation, 10.3% (39/378) were for a femoral hernia, while only 0.6% (18/3110) were for femoral hernias in males. CONCLUSION In a large multi-center cohort of mesh-based inguinal hernia repair patients, we found a higher risk for reoperation in females after an open repair approach compared to males. Lower risk was observed for females through a minimally invasive approach (laparoscopic or robotic) and may be due to the ability to identify an occult femoral hernia through these approaches.

Abstract
Gender inequities are present not only in the health status of individuals but also in access to health services. Unplanned hospitalizations can indicate dysfunction in health systems by detecting unmet health problems prior to the health care needs of a person, while planned hospitalizations indicate effective management by the system. Thus, we aim to analyze the association between sex and the probability of unplanned or planned hospitalization for different diseases. A cross-sectional retrospective study was performed with data regarding the 700 447 hospitalizations at all registered centers in the Basque Country from 2016 to 2018. Adjusted odds ratios were carried out to determine the association between sex and admission circumstances for each diagnostic category. Results showed that women had higher odds ratio for unplanned hospitalization for various diseases of the circulatory system and inguinal hernia among others, while men had a higher odds ratio for diseases such as neoplasms, metabolic diseases, and multiple sclerosis. The differences by sex indicate that the odds applied to the circumstance of hospitalization is a sensitive indicator and potentially applicable for detecting diseases likely to generate gender-based inequalities.

Abstract
BACKGROUND A groin hernia is a collective name for inguinal and femoral hernias, which can present acutely with incarceration or strangulation of the hernia sac content, requiring emergency treatment. Timely repair of emergency groin hernias is crucial due to the risk of reduced blood supply and thus damage to the bowel, but the optimal surgical approach is unclear. While mesh repair is the standard treatment for elective hernia surgery, using mesh for emergency groin hernia repair remains controversial due to the risk of surgical site infection. OBJECTIVES To assess the benefits and harms of mesh compared with non-mesh in emergency groin hernia repair in adult patients with an inguinal or femoral hernia. SEARCH METHODS On 5 August 2022, we searched the following databases: CENTRAL, MEDLINE Ovid, and Embase Ovid, as well as two trial registers for ongoing and completed trials. Additionally, we performed forward and backward citation searches for the included trials and relevant review articles. We searched without any language or publication restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing mesh with non-mesh repair in emergency groin hernia surgery in adults. We included any mesh and any non-mesh repairs. All studies fulfilling the study, participant, and intervention criteria were included irrespective of reported outcomes. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. We presented dichotomous data as risk ratios (RR) with 95% confidence intervals (CI). We based missing data analysis on best- and worst-case scenarios. For outcomes with sufficiently low heterogeneity, we performed meta-analyses using the random-effects model. We analysed subgroups when feasible, including the degree of contamination. We used RoB 2 for risk of bias assessment, and summarised the certainty of evidence using GRADE. MAIN RESULTS We included 15 trials randomising 1241 participants undergoing emergency groin hernia surgery with either mesh (626 participants) or non-mesh hernia repair (615 participants). The studies were conducted in China, the Middle East, and South Asia. Most patients were men, and most participants had an inguinal hernia (41 participants had femoral hernias). The mean/median age in the mesh group ranged from 35 to 70 years, and from 41 to 69 years in the non-mesh group. All studies were performed in a hospital emergency setting (tertiary care) and lasted for 11 to 139 months, with a median study duration of 31 months. The majority of the studies only included participants with clean to clean-contaminated surgical fields. For all outcomes, we considered the certainty of the evidence to be very low, mainly downgraded due to high risk of bias (due to deviations from intended intervention and missing outcome data), indirectness, and imprecision. Mesh hernia repair may have no effect on or slightly increase the risk of 30-day surgical site infections (RR 1.66, 95% CI 0.96 to 2.88; I² = 21%; 2 studies, 454 participants) when compared with non-mesh hernia repair, but the evidence is very uncertain. The evidence is also very uncertain about the effect of mesh hernia repair compared with non-mesh hernia repair on 30-day mortality (RR 1.38, 95% CI 0.58 to 3.28; 1 study, 208 participants). In summary, the results showed 70 more (from 5 fewer to 200 more) surgical site infections and 29 more (from 32 fewer to 175 more) deaths within 30 days of mesh hernia repair per 1000 participants compared with non-mesh hernia repair. The evidence is very uncertain about 90-day surgical site infections after mesh versus non-mesh hernia repair (RR 1.00, 95% CI 0.15 to 6.64; 1 study, 60 participants; very low-certainty evidence). No 30-day recurrences were recorded, and mesh hernia repair may not reduce recurrence within one year (RR 0.19, 95% CI 0.04 to 1.03; I² = 0%; 2 studies, 104 participants; very low-certainty evidence). Within 30 days of hernia repair, no meshes were removed from clean to clean-contaminated fields, but 6.7% of meshes (1 study, 208 participants) were removed from contaminated to dirty surgical fields. Among the four studies reporting 90-day mesh removal, no events occurred. We were not able to identify any studies reporting complications classified according to the Clavien-Dindo Classification or reoperation for complications within 30 days of repair. AUTHORS' CONCLUSIONS Our results show that in terms of 30-day surgical site infections, 30-day mortality, and hernia recurrence within one year, the evidence for the use of mesh hernia repair compared with non-mesh hernia repair in emergency groin hernia surgery is very uncertain. Unfortunately, firm conclusions cannot be drawn due to very low-certainty evidence and meta-analyses based on small-sized and low-quality studies. There is a need for future high-quality RCTs or high-quality registry-based studies if RCTs are unfeasible.

Abstract
OBJECTIVE Inguinal hernias are a common disease that may present at all ages. Adolescents are a unique patient population between children and adults. The etiology and the surgical treatment strategies of adolescent indirect hernias are not clear. Specifically, whether these kinds of hernias should be treated by high ligation or mesh repair remains controversial. We aimed to evaluate the efficacy of laparoscopic high hernia sac ligation in adolescent indirect hernia. METHODS The data of adolescent patients who underwent laparoscopic high hernia sac ligation at the The First People's Hospital of Foshan,China, from January 2012 to December 2019 were analyzed retrospectively. Data collected included their age, gender, weight, surgical method, hernia ring diameter, operation time, postoperative recurrence rate and postoperative complications. RESULTS A total of 70 patients were enrolled, including 61 males (87.14%) and 9 females (12.86%),all patients were aged 13-18 years old (mean 14.87 ± 1.56years), weighed 28-92 kg (mean 53.04 ± 10.60 kg). All 70 patients underwent laparoscopic surgery except 2 patients with irreducible hernias who converted to laparotomy.The hernia ring diameter ranged from 0.5 to 3 cm (mean 1.39 ± 0.49 cm), and was ≤ 2 cm in 68 cases (97.14%).The operative length ranged from 12 to 105 min (average 24.96 ± 12.61 min), There were 37(52.9%) right-sided hernias, 32 (45.7%) left-sided hernias, 1 (1.4%) bilateral hernia.There were 67(95.7%)reducible hernias,2(2.9%)irreducible hernias ,and 1(1.4%)incarcerated hernia.Hospital stays ranged from 1 to 5 days (mean 2.37 ± 1.05 days). Follow-ups were performed from 30-119months (mean 74.27 ± 28.14months). There were no cases of recurrence, howere, incision infection occured in 1 patient, who underwent a second operation 6 months after surgery, and 4 (5.7%) patients had complaints of intermittent pain around the ligation incision site, mostly during exercise . CONCLUSION Laparoscopic high hernia sac ligation is feasible for treatment of adolescent indirect hernias with a hernia ring diameter of ≤ 2 cm.

Abstract
BACKGROUND Emergency inguinal and femoral hernia repair can be done by suture or mesh repair, there is still scepticism around using mesh. We aim to evaluate the usage of mesh and the outcome of emergency groin hernia repair after mesh and suture repair. METHODS Retrospective cohort study of adult patients who underwent emergency inguinal and femoral hernia repair from 1st January 2018 to 31st July 2020. Electronic data and case notes were reviewed and outcome data were collected. RESULTS Eighty-nine emergency groin hernia repairs were carried out. Sixty-two were males, 60 inguinal hernia and 29 femoral hernia. Median age was 72 years (range 20-95). 74 (83.1%) were primary hernia and 15 (16.9%) recurrent hernias. 67 (75.3%) mesh and 22 (24.7%) suture repairs were carried out. Eleven cases required bowel resection and of those 10 had suture repair. Inguinal hernia was more likely to have mesh repair as compared to femoral (P-value 0.002). Median length of stay was significantly lower in mesh group 2 days (1-5 IQR) versus 7.5 days (5-11 IQR) in suture repair group (P-value <0.0001). Five cases (6.74%) had wound complications (3 wound infections, 2 haematoma). With median 20 months (range 6-36 months) follow-up, 1 recurrence each in both mesh and suture repair groups, no mesh infection and 2 (2.2%) 30-day mortality recorded. Wound infection, recurrence and reoperation were not statistically different in two groups. CONCLUSION Emergency groin hernia are amenable to mesh repair and in case of bowel resection or gross contamination non- mesh repair is recommended.

Abstract
BACKGROUND Femoral hernia (FH) is traditionally treated by open surgery (OS). Laparoscopic treatment has also shown good results in treating FH. However, there have been few comparative studies of these two techniques. Therefore, our aim was to compare the outcomes of open and laparoscopic surgical FH treatment. METHODS Adult patients with primary unilateral FH undergoing OS or transabdominal preperitoneal (TAPP) hernia repair at our hospital from January 2013 to June 2018 were included in this study. Patients with history of abdominal surgery, contraindications to general anesthesia and those not wishing to receive general anesthesia received OS. Demographics, operation details and complications were compared retrospectively between the two groups. RESULTS A total of 132 patients were recruited to the study, 62 and 70 of whom underwent OS and TAPP, respectively. Compared to OS group, the TAPP group had a significantly shorter hospital stay (3.0 vs. 2.0 days, respectively, P < 0.05) and a lower postoperative pain score (3.0 vs. 1.0, P < 0.05), and took less time to return to normal activities (13.0 vs. 6.0 days, respectively, P < 0.05). The overall complication rates were equivalent between the groups (10 vs. 9.7%, OR = 1.037, 95% CI 0.329-3.270). CONCLUSIONS Both laparoscopic and open surgery appear to be safe and effective in a cohort of patients with femoral hernia and laparoscopic surgery might offer some advantages in reducing length of hospital stay, lower postoperative pain score and quicker return to activities.

Abstract
BACKGROUND Emergency groin hernia repair is associated with increased mortality risk, but the actual risk is unknown. Therefore, this review aimed to investigate 30- and 90-day postoperative mortality in adult patients who had undergone emergency or elective groin hernia repair. METHODS This review was reported following PRISMA 2020 guidelines, and a protocol (CRD42021244412) was registered to PROSPERO. A systematic search was conducted in PubMed, EMBASE, and Cochrane CENTRAL in April 2021. Studies were included if they reported 30- or 90-day mortality following an emergency or elective groin hernia repair. Meta-analyses were conducted when possible, and subgroup analyses were made for bowel resection, sex, and hernia type. According to the study design, the risk of bias was assessed using either the Newcastle-Ottawa Scale or Cochrane Risk of Bias tool. RESULTS Thirty-seven studies with 30,740 patients receiving emergency repair and 457,253 receiving elective repair were included. The 30-day mortality ranged from 0-11.8% to 0-1.7% following emergency and elective repair, respectively. The risk of 30-day mortality following emergency repair was estimated to be 26-fold higher than after elective repair (RR = 26.0, 95% CI 21.6-31.4, I2 = 0%). A subgroup meta-analysis on bowel resection in emergency repair estimated 30-day mortality to be 7.9% (95% CI 6.5-9.3%, I2 = 6.4%). Subgroup analyses on sex and hernia type showed no differences regarding the mortality risk in elective surgery. However, femoral hernia and female sex significantly increased the risk of mortality in emergency surgery, both given by a risk ratio of 1.7. CONCLUSION The overall mortality after emergency groin hernia repair is 26-fold higher than after elective repair, but the increased risk is attributable mostly to female and femoral hernias. TRIAL REGISTRATION PROSPERO protocol (CRD42021244412).

Abstract
PURPOSE Incarcerated inguinal hernias can promote bowel ischemia. Emergent bowel resection is associated with increased postoperative morbidity. Risk factors for bowel resection might identify patients who benefit from elective inguinal hernia repair. METHODS Sixty-five consecutive patients undergoing emergency inguinal hernia repair between 2012 and 2018 at our institution were entered in a prospective database. Data analysis was approved by the local ethics committee. Patient characteristics, surgery data, and postoperative outcomes were compared between patients with and without bowel resection. Risk factors for bowel resection were assessed with univariate and multivariate analysis. RESULTS Patients requiring bowel resection were more often female (87%, P = 0.004) and presented in 67% with a femoral hernia. Postoperative complications occurred more often after hernia reduction and bowel resection compared to no resection (67% vs. 36%, P = 0.035). ASA score 3-4 and femoral herniation were independent predictors of bowel resection (P = 0,046 and P = 0,047, respectively). CONCLUSION Highly comorbid patients can profit from early elective hernia repair to prevent bowel resection.

Abstract
PURPOSE Minimally invasive approach for acute incarcerated groin hernia repair is still debated. To clarify this debate, a literature review was performed. METHODS Search was performed in PubMed, Embase, Scopus, Web of Science, and Cochrane databases, founding 28,183 articles. RESULTS Fifteen articles, and 433 patients were included (16 bilateral hernia, range 3-8). Three hundred and eighty-eight (75.3%) and 103 patients (22.9%) underwent transabdominal preperitoneal and totally extraperitoneal repair, respectively, and in 5 patients, the defect was buttressed with broad ligament (1.1%) (not specified in 3 patients). Herniated structures were resected in 48 cases (range 1-9). Intraoperative complications and conversion occurred in 4 (range 0-1) and 10 (range 0-3) patients, respectively. Mean operative time and hospital stay ranged between 50 and 147 min, and 2 and 7 days, respectively. Postoperative complications ranged between 1 and 19. Five studies compared laparoscopic and open approaches (163 and 235 patients). Herniated structures were resected in 19 (11.7%) and 42 cases (17.9%) for laparoscopic and open approach, respectively (p = 0.1191). Intraoperative complications and conversion occurred in one (0.6%) and 5 (2.1%) patients (p = 0.4077), and in two (1.2%) and 19 (8.1%) patients (p = 0.0023), in case of laparoscopic or open approach, respectively. Mean operative time and hospital stay were 94.4 ± 40.2 and 102.8 ± 43.7 min, and 4.8 ± 2.2 and 11 ± 3.1 days, in laparoscopic or open approach, respectively. Sixteen (9.8%) and 57 (24.3%) postoperative complications occurred. CONCLUSION Laparoscopy seems to be a safe and feasible approach for the treatment of acute incarcerated groin hernia. Further studies are required for definitive conclusions.

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.

[PMID: 33859994 PMCID: PMC8042323 DOI: 10.3389/fsurg.2021.655755] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 03/08/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction: While the proportion of emergency groin hernia repairs in developed countries is 2.5–7.7%, the percentage in developing countries can be as high as 76.9%. The mortality rate for emergency groin hernia repair in developed countries is 1.7–7.0% and can rise to 6–25% if bowel resection is needed. In this present analysis of data from the Herniamed Registry, patients with emergency admission and operation within 24 h are analyzed. Methods: Between 2010 and 2019 a total of 13,028 patients with emergency admission and groin hernia repairs within 24 h were enrolled in the Herniamed Registry. The outcome results were assigned to the year of repair and summarized as curves. The total patient collective is broken down into the subgroups with pre-operative manual reduction (taxis) of the hernia content, operative reduction of the hernia content without bowel resection and with bowel resection. The explorative Fisher's exact test was used for statistical assessment of significant differences with Bonferroni adjustment for multiple testing. Results: The proportion of emergency admissions with groin hernia repair within 24 h was 2.7%. The percentage of women across the years was consistently 33%. The part of femoral hernias was 16%. The proportion of patients with pre-operative reduction (taxis) remained unchanged at around 21% and the share needing bowel resection was around 10%. The proportion of TAPP repairs rose from 21.9% in 2013 to 38.0% in 2019 (p < 0.001). Between the three groups with pre-operative taxis, without bowel resection and with bowel resection, highly significant differences were identified between the patients with regard to the rates of post-operative complications (4% vs. 6.5% vs. 22.7%; p < 0.0001), complication-related reoperations (1.9% vs. 3.8% vs. 17.7%; p < 0.0001), and mortality rate (0.3% vs. 0.9% vs. 7.5%; p < 0.001). In addition to emergency groin hernia repair subgroups female gender and age ≥66 years are unfavorable influencing factors for perioperative outcomes. Conclusion: For patients with emergency groin hernia repair the need for surgical reduction or bowel resection, female gender and age ≥66 years have a highly significantly unfavorable influence on the perioperative outcomes.

Abstract
Background Transcatheter aortic valve implantation (TAVI) via total percutaneous transfemoral approach is an increasingly common technique for aortic stenosis treatment. It is primarily indicated in elderly with serious comorbidities. The epidemiology of these patients tends to overlap with the incidence of femoral hernia (FH). The appearance of hernia sac at the approach site and insufficient preoperational examination can lead to serious complications. We present the first-ever reported case of subsequent femoral hernia repair during transfemoral TAVI. Case presentation This report presents a case of FH/TAVI coincidence and literature review of its epidemiology. Literature review was performed to analyze similarities of femoral hernia and TAVI. The case describes an 84-year old female referred for elective TAVI. Intraoperation incarcerated femoral hernia was noticed and directly repaired. Further TAVI steps were performed on regular basis. A 2-year follow-up reported no local and general complications related to procedures. Conclusions Unsuspected femoral hernia found subsequently with transfemoral TAVI may become a growing problem. The number of TAVI performed rises with indications expansion. Femoral hernia repairs constitute from 2 to 4% of all groin hernia. Both TAVI and FH are connected with elderly. Despite the fact of low FH incidence, growing number of TAVI performed and ageing of population, corresponds with higher possibility of complications. Most of these complications may end up fatal as they would involve high-risk patients. Insufficient attention is paid by cardiologists to the possible hernia appearance in the access site as this issue has been hardly ever presented in literature. Concomitant FH in TAVI patients should always be excluded in order to avoid serious complications. The case we report presents a successful subsequent FH repair during TAVI procedure. Further studies have to be conducted to provide data on how such problems ought to be managed.

Abstract
BACKGROUND The rate of emergent groin hernia repair in developing countries is poorly understood. MATERIALS AND METHODS A retrospective analysis of groin hernia repairs performed at a county hospital in Guatemala [Hospital Nacional de San Benito (HSNB)] was undertaken and compared to a literature review in developed countries. Patients with incarcerated hernias were interviewed to determine factors related to late presentation. RESULTS Twenty-five percent of patients with groin hernias in this analysis presented at HNSB emergently (vs. 2.5-7.7% in developed countries). Most patients were male in their fifth decade of life. Ten percent of hernias were femoral. There was no delay in scheduling patients for surgery presenting for elective repair. Most patients lived within 20 miles of the hospital, but only 50% of patients returned for their follow-up appointment. Most patients with an incarcerated inguinal hernia (56%) did not seek medical attention because of family obligations, but when they did, this decision was influence by their children (66%). None of the patients presenting with an incarcerated hernia had education past secondary school. In fact, most (56%) did not have any form formal education. Nearly 90% of patients who had an incarcerated hernia repaired thought that the hospital provided good-to-excellent care. CONCLUSION A high number of patients present emergently for groin hernia repair at a county hospital in Guatemala compared to developed countries. Our data suggest that emergent hernias are likely the result of patient-related issues rather than health care system limitations.

Abstract
BACKGROUND Black patients and older adults are less likely to receive minimally invasive hernia repair. These differences by race and age may be influenced by surgeon-specific utilization rate of minimally invasive repair. In this study, we explored the association between race, age, and surgeon utilization of minimally invasive surgery (MIS) with the likelihood of receiving MIS inguinal hernia repair. METHODS A retrospective cohort study was performed in patients undergoing elective primary inguinal hernia repair from 2012 to 2016, using data from the Michigan Surgical Quality Collaborative, a 72-hospital clinical registry. Surgeons were stratified by proportion of MIS performed. Using hierarchical logistic regression models, we investigated the association between receiving MIS repair and race, age, and surgeon MIS utilization rate. RESULTS Out of 4667 patients, 1253 (27%) received MIS repair. Out of 190 surgeons, 81 (43%) performed only open repair. Controlling for surgeon MIS utilization, race was not associated with MIS receipt (OR 0.93, p = 0.775), but older patients were less likely to receive MIS repair (OR 0.41, p < 0.001). CONCLUSIONS Race differences were explained by surgeon MIS utilization, implicating access to MIS-performing surgeon as a mediator. Conversely, age disparity was independent of MIS utilization, even after adjusting for comorbidities, indicating some degree of provider bias against performing MIS repair in older patients. Interventions to address disparities should include systematic efforts to improve access, as well as provider and patient education for older adults.

Abstract
Background: To date, there are few studies and no systematic reviews focusing specifically on groin hernia in women. Most of the existing knowledge comes from registry data. Objective: This present review now reports on such findings as are available on groin hernia in women. Materials and Methods: A systematic search of the available literature was performed in September 2018 using Medline, PubMed, Google Scholar, and the Cochrane Library. For the present analysis 80 publications were identified. Results: The lifetime risk of developing a groin hernia in women is 3-5.8%. The proportion of women in the overall collective of operated groin hernias is 8.0-11.5%. In women, the proportion of femoral hernias is 16.7-37%. Risk factors for development of a groin hernia in women of high age and with a positive family history. A groin hernia during pregnancy should not be operated on. The rate of emergency procedures in women, at 14.5-17.0%, is 3 to 4-fold higher than in men and at 40.6% is even higher for femoral hernia. Therefore, watchful waiting is not indicated in women. During surgical repair of groin hernia in females the presence of a femoral hernia should always be excluded and if detected should be repaired using a laparo-endoscopic or open preperitoneal mesh technique. A higher rate of chronic postoperative inguinal pain must be expected in females. Conclusion: Special characteristics must be taken into account for repair of groin hernia in women.

Abstract
BACKGROUND Surgical care is essential to health systems but remains a challenge for low- and middle-income countries (LMICs). Current metrics to assess access and delivery of surgical care focus on the structural components of surgery and are not readily applicable to all settings. This study assesses a new metric for surgical care access and delivery, the ratio of emergent surgery to elective surgery (Ee ratio), which represents the number of emergency surgeries performed for every 100 elective surgeries. METHODS A systematic search of PubMed and Medline was conducted for studies describing surgical volume and acuity published between 2006 and 2016. The relationship between Ee ratio and three national indicators (gross domestic product, per capital healthcare spending, and physician density) was analyzed using weighted Pearson correlation coefficients (r w) and linear regression models. RESULTS A total of 29 studies with 33 datasets were included for analyses. The median Ee ratio was 14.6 (IQR 5.5-62.6), with a range from 1.6 to 557.4. For countries in sub-Saharan Africa the median value was 62.6 (IQR 17.8-111.0), compared to 9.4 (IQR 3.4-13.4) for the United States and 5.5 (IQR 4.4-10.1) for European countries. In multivariable linear regression, the per capita healthcare spending was inversely associated with the Ee ratio, with a 63-point decrease in the Ee ratio for each 1 point increase in the log of the per capita healthcare spending (regression coefficient β = -63.2; 95% CI -119.6 to -6.9; P = 0.036). CONCLUSIONS The Ee ratio appears to be a simple and valid indicator of access to available surgical care. Global health efforts may focus on investment in low-resource settings to improve access to available surgical care.

Abstract
BACKGROUND MIS utilization for inguinal hernia repair is low compared to in other procedures. The impact of low adoption in surgeons is unclear, but may affect regional access to minimally invasive surgery (MIS). We explored the impact of surgeon MIS utilization in inguinal hernia repair across a statewide population. METHODS We analyzed 6723 patients undergoing elective inguinal hernia repair from 2012 to 2016 in the Michigan Surgical Quality Collaborative. The primary outcome was surgeon MIS utilization. The geographic distribution of high MIS-utilizing surgeons was compared across Hospital Referral Regions using Pearson's Chi-squared test. Hierarchical logistic regression was used to identify patient and hospital factors associated with MIS utilization. RESULTS Surgeon MIS utilization varied, with 58% of 540 surgeons performing no MIS repair. For the remaining surgeons, MIS utilization was bimodally distributed. High-utilization surgeons were unevenly distributed across region, with corresponding differences in regional MIS rate ranging from 10 to 48% (p < 0.001). MIS was used in 41% of bilateral and 38% of recurrent hernia. MIS repair was more likely with higher hospital volume and less likely for patients aged 65+ (OR 0.68, p = 0.003), black patients (OR 0.75, p = 0.045), patients with COPD (OR 0.57, p < 0.001), and patients in ASA class > 3 (OR 0.79 p < 0.001). CONCLUSIONS MIS utilization varies between surgeons, likely driving differences in regional MIS rates and leading to guideline-discordant care for patients with bilateral or recurrent hernia. Interventions to reduce this practice gap could include training programs in MIS repair, or regionalization of care to improve MIS access.

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
Hernioscopy is essentially hernia sac laparoscopy. Hernia repair has evolved over the years with better outcomes; however, strangulated inguinal hernias are acute surgical emergencies which require emergent operative intervention. During anesthesia induction and/or after incision, hernia self-reduction is possible, with or without compromised bowel, back into the abdominal cavity. It is pivotal to examine the bowel to decide on further operative course. A simple alternative to unnecessary laparotomy or standard laparoscopy is hernioscopy, which is quite uncommon. We present a case of an acute symptomatic strangulated left-sided inguinal hernia which got self-reduced during anesthesia induction and was successfully repaired after hernioscopy was used to evaluate the incarcerated hernia content. We provide a brief review of literature about hernioscopy and an algorithm to guide surgeons in emergent cases.

Abstract
BACKGROUND Clinical treatment guidelines have suggested that laparoscopic hernia repair should be the preferred approach in both men and women with bilateral or recurrent elective groin hernias. Anecdotal evidence suggests, however, that women are less likely to undergo a laparoscopic repair than men, and therefore, we aimed to delineate if these disparities persisted after controlling for patient factors and comorbidities. MATERIALS AND METHODS The American College of Surgeons National Surgical Quality Improvement Project data were abstracted for all elective groin hernia repairs between 2005 and 2014. Univariate analysis was used to compare rates of laparoscopic surgery between men and women. Multivariable analysis was performed, controlling for patient demographics, preoperative comorbidities, and year of surgery. RESULTS Over the 10-y period, 141,490 patients underwent elective groin hernia repair, of which 13,325 were women (9.4%). The rate of general anesthesia utilization was high in both men (81.3%) and women (77.2%) with 75.1% of open repairs being performed under general anesthesia. Overall, 20.2% of women underwent laparoscopic repair compared with 28.0% of men (P < 0.01). Women tended to be older, had a lesser body mass index, and slightly greater American Anesthesia Association (all P < 0.05). On multivariable regression, women had decreased odds of undergoing a laparoscopic approach compared with men (odds ratio: 0.70; 95% confidence interval, 0.67-0.73, P < 0.01). CONCLUSIONS In the elective setting, women were less likely to undergo laparoscopic repair of groin hernias than men. Although we are unable to ascertain underlying causes for these gender disparities, these data suggest that there remains a disparity in the management of groin hernias in women.

Trends in operation rates for inguinal hernia over five decades in England: database study. Hernia 2014; 19:713-8.

Abstract
PURPOSE We aimed to study trends over time in operation rates for inguinal hernia with and without obstruction over five decades. METHODS Routine hospital statistics were used to analyse trends in National Health Service hospitals in England (1968-2011). RESULTS All-England admission rates for elective repair of unobstructed inguinal hernia in males were 240.8 episodes per 100,000 population [95 % confidence interval (CI) 234.5-247.2] in 1968 and were relatively stable until 2003 after which they declined to 217.1 (215.4-218.8) by 2011. However, the stability of the all ages rates masked a large decline in admission rates in the young (e.g. 425 per 100,000 in 1968-1970 in males under 1 year of age, down to 155 per 100,000 in 2007-2011) and a large increase in the elderly (e.g. 247 in 1968-1970 per 100,000 males aged 75-84, up to 799 per 100,000 in 2007-2011). All-England admission rates for obstructed inguinal hernia in males almost halved, from 19.3 episodes (17.4-21.2) in 1968 to 10.7 episodes (10.3-11.0) per 100,000 population in 2011. Admission rates for females gradually declined over time for both unobstructed and obstructed inguinal hernia. CONCLUSION Hospital admission rates for elective operation on inguinal hernia without obstruction, for all ages combined, have been relatively stable over five decades, but this masked big differences between age groups. Rates of obstructed hernia have declined over time, particularly in the early years covered by the study, and have not shown an increase associated with the recent fall in elective surgery for hernia repair.

Abstract
Observation is an acceptable management strategy for asymptomatic and minimally symptomatic inguinal hernias because it is safe. The rate of hernia accident is very low and is not an indication for surgery. However, patients who present to their physician with a hernia will almost certainly undergo a hernia repair if they live long enough.

Abstract
INTRODUCTION Non-communicable diseases including surgical conditions are gaining attention in developing countries. Despite this there are few metrics for surgical capacity. We hypothesized that (a) the ratio of emergent to total hernia repairs (E/TH) would correlate with per capita health care expenditures for any given country, and (b) the E/TH is easy to obtain in resource-poor settings. METHODS We performed a systematic review to identify the E/TH for as many countries as possible (Prospero registry CRD42013004645). We screened 1285 English language publications since 1990; 23 met inclusion criteria. Primary data was also collected from Kamuzu Central Hospital (KCH) in Lilongwe, Malawi. A total of 13 countries were represented. Regression analysis was used to determine the correlation between per capita health care spending and the E/TH. RESULTS There is a strong correlation between the log values of the ratio emergent to total groin hernias and the per capita health care spending that is robust across country income levels (R(2) = 0.823). Primary data from KCH was easily obtained and demonstrated a similar correlation. CONCLUSIONS The ratio of emergent to total groin hernias is a potential measure of surgical capacity using data that is easily attainable. Further studies should validate this metric against other accepted health care capacity indicators. Systematic review registered with Prospero (CRD42013004645).
