Perioperative Risk Factors for Persistent Postsurgical Pain After Inguinal Hernia Repair: Systematic Review and Meta-Analysis. THE JOURNAL OF PAIN 2024; 25:104532. [PMID: 38599265 DOI: 10.1016/j.jpain.2024.104532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 04/04/2024] [Accepted: 04/04/2024] [Indexed: 04/12/2024]
Abstract
Persistent postsurgical pain (PPSP) is one of the most bothersome and disabling long-term complications after inguinal hernia repair surgery. Understanding perioperative risk factors that contribute to PPSP can help identify high-risk patients and develop risk-mitigation approaches. The objective of this study was to systematically review and meta-analyze risk factors that contribute to PPSP after inguinal hernia repair. The literature search resulted in 303 papers included in this review, 140 of which were used for meta-analyses. Our results suggest that younger age, female sex, preoperative pain, recurrent hernia, postoperative complications, and postoperative pain are associated with a higher risk of PPSP. Laparoscopic techniques reduce the PPSP occurrence compared to anterior techniques such as Lichtenstein repair, and tissue-suture techniques such as Shouldice repair. The use of fibrin glue for mesh fixation was consistently associated with lower PPSP rates compared to tacks, staples, and sutures. Considerable variability was observed with PPSP assessment and reporting methodology in terms of study design, follow-up timing, clarity of pain definition, as well as pain intensity or interference threshold. High or moderate risk of bias in at least one domain was noted in >75% of studies. These may limit the generalizability of our results. Future studies should assess and report comprehensive preoperative and perioperative risk factors for PPSP adjusted for confounding factors, and develop risk-prediction models to drive stratified PPSP-mitigation trials and personalized clinical decision-making. PERSPECTIVE: This systematic review and meta-analysis summarizes the current evidence on risk factors for persistent pain after inguinal hernia repair. The findings can help identify patients at risk and test personalized risk-mitigation approaches to prevent pain.

Deveci CD, Öberg S, Rosenberg J. Definition of Mesh Weight and Pore Size in Groin Hernia Repair: A Systematic Scoping Review of Randomised Controlled Trials. JOURNAL OF ABDOMINAL WALL SURGERY : JAWS 2023; 2:11179. [PMID: 38312405 PMCID: PMC10831688 DOI: 10.3389/jaws.2023.11179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 03/28/2023] [Indexed: 02/06/2024]
Abstract
Introduction: Groin hernia literature often uses the terms light- and heavyweight and small or large pores to describe meshes. There is no universal definition of these terms, and the aim of this scoping review was to assess how mesh weight and pore sizes are defined in the groin hernia literature. Methods: In this systematic scoping review, we searched PubMed, Embase, and Cochrane CENTRAL. We included randomised controlled trials with adults undergoing groin hernia repair with the Lichtenstein or laparoscopic techniques using a flat permanent polypropylene or polyester mesh. Studies had to use the terms lightweight, mediumweight, or heavyweight to be included, and the outcome was to report how researchers defined these terms as well as pore sizes. Results: We included 48 studies with unique populations. The weight of lightweight meshes ranged from 28 to 60 g/m2 with a median of 39 g/m2, and the pore size ranged from 1.0 to 4.0 mm with a median of 1.6 mm. The weight of heavyweight meshes ranged from 72 to 116 g/m2 with a median of 88 g/m2, and the pore size ranged from 0.08 to 1.8 mm with a median of 1.0 mm. Only one mediumweight mesh was used weighing 55 g/m2 with a pore size of 0.75 mm. Conclusion: There seems to be a consensus that meshes weighing less than 60 g/m2 are defined as lightweight and meshes weighing more than 70 g/m2 are defined as heavyweight. The weight terms were used independently of pore sizes, which slightly overlapped between lightweight and heavyweight meshes.

Varying convalescence recommendations after inguinal hernia repair: a systematic scoping review. Hernia 2022; 26:1009-1021. [PMID: 35768670 DOI: 10.1007/s10029-022-02629-3] [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: 01/18/2022] [Accepted: 05/05/2022] [Indexed: 11/04/2022]
Abstract
PURPOSE The most recent international guideline on inguinal hernia management recommends a short convalescence after repair. However, surgeons' recommendations may vary. The objective of this study was to give an overview of the current convalescence recommendations in the literature subdivided on the Lichtenstein and laparoscopic inguinal hernia repairs. METHODS In this systematic review, three databases were searched in August 2021 to identify studies on inguinal hernia repairs with a statement about postoperative convalescence recommendations. The outcome was convalescence recommendations subdivided on daily activities, light work, heavy lifting, and sport. RESULTS In total, 91 studies fulfilled the eligibility criteria, and 50 and 58 studies reported about convalescence recommendations after Lichtenstein and laparoscopic repairs, respectively. Patients were instructed with a wide range of convalescence recommendations. A total of 34 Lichtenstein studies and 35 laparoscopic studies recommended resumption of daily activities as soon as possible. Following Lichtenstein repairs, the patients were instructed to resume light work after median 0 days (interquartile range (IQR) 0-0), heavy lifting after 42 days (IQR 14-42), and sport after 7 days (IQR 0-29). Following laparoscopic procedures, the patients were instructed to resume light work after median 0 days (IQR 0-0), heavy lifting after 14 days (IQR 10-28), and sport after 12 days (IQR 7-23). CONCLUSION This study revealed a broad spectrum of convalescence recommendations depending on activity level following inguinal hernia repair, which likely reflects a lack of high-quality evidence within this field.

Abstract
This study reports that a methacrylic acid (MAA)-based copolymer coating generates constructive remodeling of polypropylene (PP) surgical mesh in a subcutaneous model. This coating is non-bioresorbable and follows the architecture of the mesh without impeding connective tissue integration. Following implantation, the tissue response is biased toward vascularization instead of fibrosis. The vessel density around the MAA mesh is double that of the uncoated mesh two weeks after implantation. This initial vasculature regresses after two weeks while mature vessels remain, suggesting an enhanced healing response. Concurrently, the MAA coating alters the foreign body response to the mesh. Fewer infiltrating cells, macrophages, and foreign body giant cells are found at the tissue-material interface three weeks after implantation. The coating also dampens inflammation, with lower expression levels of pro-inflammatory and fibrogenic signals (e.g., Tgf-β1, Tnf-α, and Il1-β) and similar expression levels of anti-inflammatory cytokines (e.g., Il10 and Il6) compared to the uncoated mesh. Contrary to other coatings that aim to mitigate the foreign body response to PP mesh, a MAA coating does not require the addition of any biological agents to have an effect, making the coated mesh an attractive candidate for soft tissue repair.

Abstract
PURPOSE This study aimed to determine if the prognoses of inguinal hernia patients improved with the application of lightweight mesh (LWM). METHODS Medline, Embase, and Cochrane library were searched for randomized controlled trails related to laparo-endoscopic inguinal hernia repair with different prosthetic meshes. Data were extracted and analyzed using the guidelines of the Cochrane handbook. The primary endpoints were recurrence and chronic postoperative inguinal pain. The second endpoints encompassed acute postoperative pain, foreign body sensation, seroma, infection, and numbness. Data were processed using Review Manager 5.3. RESULTS The heavyweight mesh (HWM) had a distinctive advantage for recurrence (RR 2.30; 95% CI 1.21-4.38; P = 0.01), with comparable results for postoperative pain (RR 0.91; 95% CI 0.37-2.22; P = 0.83), foreign body sensation (RR 1.18; 95% CI 0.91-1.51; P = 0.21), seroma(RR 0.87; 95% CI 0.75-1.01; P = 0.06), infection (RR 0.85; 95% CI 0.31-2.34; P = 0.75), and numbness, compared to LWM. CONCLUSION HWM had a distinctive advantage over LWM with regard to recurrence. The two types of prosthetic meshes had equivalent outcomes for postoperative pain, seroma, foreign body sensation, infection, and numbness. Studies focused on defect sizes and fixation methods are warranted for further stratification.

Abstract
Background: There is no consensus on whether lightweight mesh (LWM) is better than heavyweight mesh (HWM) in laparoscopic inguinal hernia repair (LIHR). This study aims to update the previous reviews and to analyze present randomized controlled studies comparing LWM versus HWM in LIHR systematically. Methods: We searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs), which compared LWM with HWM in adults with LIHR. All eligible data of outcomes were quantitatively analyzed using Revman 5.3 software or qualitatively described. The outcomes included chronic pain, moderate-severe chronic pain, recurrence, foreign body sensation, influence on sexual life and male fertility (pain with ejaculation, testicular pain, etc.). Results: We included 12 RCTs that analyzed 3092 hernias. The difference between LWM and HWM groups at any follow-up time was not significant in chronic pain and foreign body sensation. Compared with HWM group, patients in LWM group had a similar risk of postoperative moderate-severe chronic pain at 3 and 12 months follow-up, a slightly increased risk of developing moderate-severe chronic pain at >12 months follow-up (risk ratio [RR] = 3.20, 95% confidence interval [CI] 1.05-9.75, P = .04), and a higher risk of recurrence rate (RR = 2.28, 95% CI 1.17-4.44, P = .02). At long-term follow-up, the influences of LWM and HWM on sexual life and male fertility were comparable. Conclusion: LWMs do not show advantages in chronic pain, foreign body sensation as well as the influence on sexual life and male fertility, and may increase hernia recurrence rates for LIHR. In addition, a higher incremental cost and lower incremental effect of LWMs make conventional HWMs preferred choice for LIHR.

Abstract
The aim of this study was to compare the outcomes of lightweight and heavyweight mesh on postoperative recovery in laparoscopic total extraperitoneal (TEP) inguinal hernia repair. PubMed, Embase, Science Citation Index, and the Cochrane Library were used to search for published clinical randomized controlled trials, which compared lightweight meshes with heavyweight meshes in TEP inguinal hernia repair. The outcomes were calculated as risk ratios with 95 per cent confidence intervals using RevMan 5.2. Eight randomized controlled trials were included. Compared with a heavyweight mesh, the lightweight mesh led to a higher incidence of recurrence (risk ratio = 2.52, 95% confidence interval 1.10–5.81; P = 0.03). There was no significant difference in chronic moderate to severe pain, foreign body sensation, and seroma. The use of lightweight mesh is not recommended for TEP inguinal hernia repair.

Abstract
PURPOSE The PINQ-PHONE is a 4-question telephone questionnaire designed and validated as a recurrence detection method after laparo-endoscopic inguinal hernia repair. The study aim was to evaluate the PINQ-PHONE by describing our experience with the questionnaire in a high-volume randomized-controlled trial. METHODS The PINQ-PHONE was performed 5 years postoperatively after endoscopic totally extraperitoneal (TEP) repair. Positive PINQ-PHONE responses were compared with clinical assessments for a recurrence. An "experience with the PINQ-PHONE"-survey was conducted among the executing researchers. Furthermore, positive predictive values (PPV) for the separate questions and overall PINQ-PHONE were determined. RESULTS Fifty-two of 769 responding patients (6.8%) had positive PINQ-PHONE responses and were invited to visit the outpatient clinic, thus preventing follow-up visits in 93.2% of included patients. Two recurrences were detected (0.3%). The overall PPV of the PINQ-PHONE was low (0.057). The PPV of question 1 (0.040) and 2 (0.100) was lower than that of question 3 (0.222) and 4 (0.286). The PPV of only question 3 and 4 combined was 0.183, and no recurrence would have been missed. The researcher survey unanimously produced that the PINQ-PHONE was user-friendly and executed in < 5 min, and questions 3 and 4 were considered adequate for recurrence detection. The majority found questions 1 and 2 to be inadequate questions. CONCLUSIONS The PINQ-PHONE proved to be a valuable tool in TEP repair follow-up for recurrences. Enhancement of the PINQ-PHONE using only question 3 and 4 is recommended, since more patients refrain from outpatient clinic visits, and nevertheless, recurrences are safely detected.

Abstract
INTRODUCTION Tension-free mesh repair is currently the gold standard treatment for inguinal hernia. Recent evidence has shown that both open and laparoscopic approaches to inguinal hernia repair can achieve good results. Lots of meshes with different properties are available on the market, but direct comparisons between them are scare. We conducted a prospective randomized controlled trial comparing a partially absorbable lightweight mesh (ULTRAPRO™) and a multifilament polyester anatomical mesh (Parietex™) in laparoscopic total extraperitoneal inguinal hernia repair. METHODS This study was a single-center, prospective randomized controlled trial to compare the surgical handling and clinical outcomes between two different types of meshes. All operations were performed using a standardized operative protocol. This study was approved by the Institutional Review Board of the Hong Kong East Cluster Health Service in 2009 (reference number: 2009-087). The study was registered in the Australian New Zealand Clinical Trial Registry (ACTRN12610000031066). RESULTS From October 2009 to August 2011, 85 laparoscopic total extraperitoneal inguinal hernia repairs were performed. The mean mesh handling time was 152 s for the ULTRAPRO group and 206 s for the Parietex group (P = 0.001). There were three cases of seroma formation in the ULTRAPRO group and nine in the Parietex group (P = 0.02). The overall recurrence rate was 2.5%. CONCLUSION It took less time to manipulate the flat mesh (ULTRAPRO) than the anatomical mesh (Parietex) in laparoscopic total extraperitoneal inguinal hernia repair, but the time difference was small. Lightweight mesh and heavyweight mesh offered similar clinical outcomes in terms of discomfort sensation and foreign body sensation during long-term follow-up.

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.

[PMID: 29250511 PMCID: PMC5729126 DOI: 10.4174/astr.2017.93.6.316] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2017] [Revised: 05/16/2017] [Accepted: 05/30/2017] [Indexed: 11/30/2022] Open
Abstract
Purpose Partially absorbable mesh has been introduced and used for inguinal hernia repair for the purpose of minimizing pain and improving abdominal wall compliance. In this study, we evaluate the efficacy and safety of ProFlex mesh, a partially absorbed mesh with new structural architecture. Methods We retrospectively reviewed 64 cases of totally extraperitoneal herniorrhapy (TEP) from January 2013 to December 2014 for their clinical features, including operation time, pain, postoperative complications, and recurrence. Results There were no significant differences in operation time, hospital stay, postoperative pain, or complications between the 28 patients who received the ProFlex mesh and the 36 who received nonabsorbable lightweight mesh, although one patient who received the nonabsorbable had a recurrence during follow-up. There were differences in operation time, complications, and hospital stay according to the surgeon's previous operation volume. Conclusion This study showed that there were significant differences in the fixation strength of different polypropylene meshes in combination with various fibrin glues. ProFlex, a partially absorbable mesh with new architecture, was feasible and safe in TEP.

Abstract
OBJECTIVE The aim of the randomized clinical trial was to compare the 2 years of clinical outcomes of a lightweight (Ultrapro) vs a heavyweight (Prolene) mesh for laparoscopic total extraperitoneal (TEP) inguinal hernia repair. BACKGROUND Lightweight meshes reduce postoperative pain and stiffness in open anterior inguinal hernia repair. The discussion about a similar benefit for laparoscopic repair is ongoing, but concerns exist about higher recurrence rates. METHODS Between March 2010 and October 2012, male patients who presented with a primary, reducible unilateral inguinal hernia who underwent day-case TEP repair were eligible. Outcome parameters included chronic pain, recurrence, foreign body feeling, and quality of life scores. RESULTS During the study period, 950 patients were included. One year postoperatively the presence of relevant pain (Numeric Rating Score 4-10) was significantly higher in the lightweight mesh group (2.9%) compared with the heavyweight mesh group (0.7%) (P = 0.01), and after 2 years this difference remained significant (P = 0.03). There were 4 (0.8%) recurrent hernias in the heavyweight mesh group and 13 (2.7%) in the lightweight group (P = 0.03). No differences in foreign body feeling or quality of life scores were detected. CONCLUSIONS In TEP hernia surgery, there was no benefit of lightweight over heavyweight meshes observed 2 years postoperatively.

Abstract
INTRODUCTION Chronic inguinal pain is a frequently occurring problem in athletes. A diagnosis of inguinal disruption is performed by exclusion of other conditions causing groin pain. Up to now, conservative medical management is considered to be the primary treatment for this condition. Relevant large and prospective clinical studies regarding the treatment of inguinal disruption are limited; however, recent studies have shown the benefits of the totally extraperitoneal patch (TEP) technique.This study provides a complete assessment of the inguinal area in athletes with chronic inguinal pain before and after treatment with the TEP hernia repair technique. METHODS AND ANALYSIS We describe the rationale and design of an observational cohort study for surgical treatment with the endoscopic TEP hernia repair technique in athletes with a painful groin (inguinal disruption).The study is being conducted in a high-volume, single centre hospital with specialty in TEP hernia repair. Patients over 18 years, suffering from inguinal pain for at least 3 months during or after playing sports, and whom have not undergone previous inguinal surgery and have received no benefit from physiotherapy are eligible for inclusion. Patients with any another cause of inguinal pain, proven by physical examination, inguinal ultrasound, X-pelvis/hip or MRI are excluded.Primary outcome is reduction in pain after 3 months. Secondary outcomes are pain reduction, physical functioning, and resumption of sport (in frequency and intensity). ETHICS AND DISSEMINATION An unrestricted research grant for general study purposes was assigned to the Hernia Centre. This study itself is not directly subject to the above mentioned research grant or any other financial sponsorship. We intend to publish the outcome of the study, regardless of the findings. All authors will give final approval of the manuscript version to be published.
