Abstract
BACKGROUND There is still controversy surrounding routine ilioinguinal neurectomy in open tension-free inguinal hernia repair. METHOD PubMed, Cochrane Library and EMBASE databases were searched for randomized controlled trials of ilioinguinal neurectomy in open tension-free inguinal hernia repair. Revman 5.3 software was used for meta-analysis. RESULT Meta-analysis revealed that the incidence of severe pain on the first postoperative day was lower in the ilioinguinal neurectomy group (ING) than in the ilioinguinal nerve preservation group (INPG) [P < 0.0001]. The incidence of no pain in the first month postoperatively [P = 0.0004], the incidence of no pain in the sixth months postoperatively [P < 0.00001], and the numbness incidence in the first month postoperatively [P = 0.001] in the ING was higher than that in the INPG. There was no significant difference in the incidence of severe pain in the first month postoperatively [P = 0.20], the numbness incidence in the sixth postoperative month [P = 0.05], the hypoesthesia incidence in the first [P = 0.15] and sixth [P = 0.85] postoperative months between the two groups. CONCLUSION Ilioinguinal neurectomy in open tension-free inguinal hernia repair can better prevent postoperative pain.

Abstract
Introduction To date, Lichtenstein tension-free mesh hernioplasty is being adopted widely for inguinal hernia repair in adults, although it is accompanied by procedural complications such as recurrences, infection, testicular atrophy, post-operative pain, and nerve injury. As the recurrence rate decreased after Lichtenstein's tension-free hernioplasty, surgeons’ point of focus shifted more toward postoperative groin pain (inguinodynia) after inguinal hernia repair, as it has become a quite significant problem. The nerves of interest in the inguinal region are ilioinguinal, iliohypogastric, genitofemoral, and lateral femoral cutaneous nerves. Out of all the nerves, the ilioinguinal nerve is at the greatest risk of entrapment during meshplasty. Chronic groin pain is quite significant following hernia repair, and irrespective of the severity, it can interfere with normal daily activity. The traditional surgical technique recommends the preservation of the ilioinguinal nerve to avoid the morbidity associated with the cutaneous sensory loss supplied by the nerve. One popular belief is that if we excise the ilioinguinal nerve, then the chance of getting post-operative neuralgia due to entrapment, inflammation, neuroma, or fibrotic reactions will almost become zero. Hence, this study was conducted to evaluate the effect of prophylactic excision of the ilioinguinal nerve in the patients undergoing Lichtenstein hernioplasty for inguinal hernias. Methods All consecutive male patients presenting to the Department of Surgery with inguinal hernia and age above 18 years were included in the study. All the patients were operated on under spinal anesthesia. Lichtenstein tension-free hernia repair was taken as the standard procedure for hernia repair. Patients in whom the nerve was preserved were kept in group A, whereas group B comprised patients who had undergone neurectomy. Patients were followed up regarding pain at first, third, and sixth months, at rest, and after exercise. The pain was graded according to the VAS (visual analog scale) scoring. Results In the present study, out of a total of 92 patients, 80 patients were included. In the first month, 15% of the patients in group A had mild pain, while 5% in group B had experienced a moderate degree of pain at rest. After exercise, the result was 30% in group B. Similarly, in the third month of follow-up, it was found that 25% of the patients in group A experienced mild pain, while 12.5% complained about a moderate degree of pain who had to take analgesics for a longer period. After putting them to exercise and then grading the pain, it was found that 32.5% in group A and 15% in group B experienced pain. After follow-up for six months in both groups, it was revealed that there was no significant difference in post-operative pain at rest (10% and 7.5% in groups A and B, respectively). After exercise, 20% of patients in group A complained of pain, while in group B, only 10% experienced pain. There was no significant difference between both the groups while comparing chronic groin pain at rest and after exercise, and after different time intervals in follow-up (p = 0.4513 and 0.548, respectively). Conclusion Prophylactic excision of the ilioinguinal nerve in Lichtenstein tension-free meshplasty decreased the incidence of chronic groin pain after surgery but it was statistically insignificant. Furthermore, this procedure did not affect the quality of life after surgery.

Abstract
OBJECTIVE This study aimed to evaluate the incidence of chronic groin pain (primary outcome) and alterations of sensitivity (secondary outcome) after Lichtenstein inguinal hernia repair, comparing neurectomy with ilioinguinal nerve preservation surgery. The exact cause of chronic groin postoperative pain after mesh inguinal hernia repair is usually unclear. Section of the ilioinguinal nerve (neurectomy) may reduce postoperative chronic pain. METHODS We followed PRISMA guidelines to identify randomized studies reporting comparative outcomes of neurectomy versus ilioinguinal nerve preservation surgery during Lichtenstein hernia repairs. Studies were identified by searching in PubMed, Scopus, and Web of Science from April 2020. The protocol for this systematic review and meta-analysis was submitted and accepted from PROSPERO: CRD420201610. RESULTS In this systematic review and meta-analysis, 16 RCTs were included and 1550 patients were evaluated: 756 patients underwent neurectomy (neurectomy group) vs 794 patients underwent ilioinguinal nerve preservation surgery (nerve preservation group). All included studies analyzed Lichtenstein hernia repair. The majority of the new studies and data comes from a relatively narrow geographic region; other bias of this meta-analysis is the suitability of pooling data for many of these studies. A statistically significant percentage of patients with prosthetic inguinal hernia repair had reduced groin pain at 6 months after surgery at 8.94% (38/425) in the neurectomy group versus 25.11% (113/450) in the nerve preservation group [relative risk (RR) 0.39, 95% confidence interval (CI) 0.28-0.54; Z = 5.60 (P < 0.00001)]. Neurectomy did not significantly increase the groin paresthesia 6 months after surgery at 8.5% (30/353) in the neurectomy group versus 4.5% (17/373) in the nerve preservation group [RR 1.62, 95% CI 0.94-2.80; Z = 1.74 (P = 0.08)]. At 12 months after surgery, there is no advantage of neurectomy over chronic groin pain; no significant differences were found in the 12-month postoperative groin pain rate at 9% (9/100) in the neurectomy group versus 17.85% (20/112) in the inguinal nerve preservation group [RR 0.50, 95% CI 0.24-1.05; Z = 1.83 (P = 0.07)]. One study (115 patients) reported data about paresthesia at 12 months after surgery (7.27%, 4/55 in neurectomy group vs. 5%, 3/60 in nerve preservation group) and results were not significantly different between the two groups [RR 1.45, 95% CI 0.34, 6.21;Z = 0.51 (P = 0.61)]. The subgroup analysis of the studies that identified the IIN showed a significant reduction of the 6th month evaluation of pain in both groups and confirmed the same trend in favor of neurectomy reported in the previous overall analysis: statistically significant reduction of pain 6 months after surgery at 3.79% (6/158) in the neurectomy group versus 14.6% (26/178) in the nerve preservation group [RR 0.28, 95% CI 0.13-0.63; Z = 3.10 (P = 0.002)]. CONCLUSION Ilioinguinal nerve identification in Lichtenstein inguinal hernia repair is the fundamental step to reduce or avoid postoperative pain. Prophylactic ilioinguinal nerve neurectomy seems to offer some advantages concerning pain in the first 6th month postoperative period, although it might be possible that the small number of cases contributed to the insignificancy regarding paresthesia and hypoesthesia. Nowadays, prudent surgeons should discuss with patients and their families the uncertain benefits and the potential risks of neurectomy before performing the hernioplasty.

The outcomes of routine ilioinguinal neurectomy in the treatment of chronic pain during herniorrhaphy: A meta-analysis of randomized-controlled trials. Asian J Surg 2020; 44:431-439. [PMID: 33250275 DOI: 10.1016/j.asjsur.2020.10.022] [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: 07/11/2020] [Revised: 10/19/2020] [Accepted: 10/29/2020] [Indexed: 11/20/2022] Open
Abstract
The study aimed to evaluate whether an intraoperative ilioinguinal neurectomy (IIN) would reduce the risk of postoperative pain without increasing other complications during tension-free mesh repair compared to those who accepting nerve preservation. We have searched the following databases: PubMed, Cochrane Library, and EMBASE from inception to January 2020 (the cut-off date was 1 January 2020). Two authors independently accomplished the study selection, data extraction, and quality assessment. Of 553 studies reviewed, 7 high-quality randomized-controlled trials (RCTs) were identified. We pooled the related effect values in each included study and conducted a meta-analysis. The pooled results showed that IIN could reduce postoperative pain rate (RR = 0.40, 95% CI: 0.17-0.95) and pain score (SMD = -0.26, 95%CI: -0.46 to -0.06) at 6 months. There are no statistical differences between postoperative numbness rate (RR = 1.48, 95%CI: 0.89-2.47), postoperative sensory disturbance (RD = 0.03, 95% CI: -0.03-0.1) and postoperative secondary complications rate (RR = 0.81, 95%CI: 0.53-1.24) at the same time point. In conclusion, we have found the routine IIN can reduce the incidence of postoperative pain without increasing complications. Therefore, the implementation of this simple intraoperative maneuver may be a major source of postoperative morbidity reduction. Further study on the evaluation of interventions targeted to the IIN is recommended.

Incidence of chronic groin pain following open mesh inguinal hernia repair, and effect of elective division of the ilioinguinal nerve: meta-analysis of randomized controlled trials. Hernia 2018; 22:401-409. [PMID: 29550948 DOI: 10.1007/s10029-018-1753-9] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2017] [Accepted: 02/13/2018] [Indexed: 12/26/2022]
Abstract
PURPOSE Chronic post-operative groin pain is a substantial complication following open mesh inguinal hernia repair. The exact cause of this pain is still unclear, but entrapment or trauma of the ilioinguinal nerve may have a role to play. Elective division of this nerve during hernia repair has been proposed in an attempt to reduce the incidence of chronic groin pain. METHODS We performed a meta-analysis of nine randomized controlled trials comparing preservation versus elective division of the ilioinguinal nerve during this operation. RESULTS A substantial proportion of patients having open mesh inguinal hernia repair experience chronic groin pain when the ilioinguinal nerve is preserved (estimated rate of 9.4% at 6 months and 4.8% at 1 year). Elective division of the nerve resulted in a significant reduction of groin pain at 6-months post-surgery (RR 0.47, p = 0.02), including moderate/severe pain (RR 0.57, p = 0.01). However, division of the nerve also resulted in an increase of subjective groin numbness at this time point (RR 1.55, p = 0.06). At 12-month post-surgery, the beneficial effect of nerve division on chronic pain was reduced, with no significant difference in the rates of overall groin pain (RR 0.69, p = 0.38), or of moderate-to-severe groin pain (RR 0.99, p = 0.98) between the two groups. The prevalence of groin numbness was also similar between the two groups at 12-month post-surgery (RR 0.79, p = 0.48). CONCLUSIONS Routine elective division of the ilioinguinal nerve during open mesh inguinal hernia repair does not significantly reduce chronic groin pain beyond 6 months, and may result in increased rates of groin numbness, especially in the first 6-months post-surgery.

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
OBJECTIVE The aim of the study was to establish whether an inguinal neurectomy at the time of hernia repair would reduce the risk of postoperative pain for open tension-free sutured mesh repair. BACKGROUND Inguinal hernia repair is a common operative procedure. The development of postoperative pain is uncommon, but at times debilitating. The role of inguinal neurectomy is currently unknown, with no single large study available, and previous reviews included only a few heterogeneous studies. METHODS Relevant randomized trials were identified from searches of MEDLINE, EMBASE, and EBM Review databases until October 2014. Meta-analysis was performed based on Cochrane Methods using RevMan v5.3 software. Pain, pain scores, sensory changes, and complications over short (half to <3 months), mid (3 to <12 mo), and long term (≥12 mo) were recorded. RESULTS All included studies performed Lichtenstein hernia repair. Eleven studies on 1031 patients showed significant reduction in pain with neurectomy for short (RR = 0.61, 0.40-0.93) and midterm (RR = 0.30, 0.20-0.46), but not for long term (RR = 0.50, 0.25-1.01). Three studies (270 patients) showed significantly reduced short-term pain (RR = 0.69, 0.52-0.90). No studies included genitofemoral neurectomy. Rates of hematoma, infection, urinary retention, and recurrence were not different between groups. CONCLUSIONS Routine ilioinguinal neurectomy during Lichtenstein-type herniorrhaphy seems to be a safe and effective method to reduce pain in the short and midterm, but may have little long-term impact. Iliohypogastric neurectomy seems to reduce pain in at least the short term.

Abstract
Pain occurs in the male genitourinary organs as for any organ system in response to traumatic, infectious, or irritative stimuli. A knowledge and understanding of chronic genitourinary pain can be of great utility to practicing nonurologists. This article provides insight into the medical and surgical management of subacute and chronic pelvic, inguinal, and scrotal pain. The pathophysiology, diagnosis, and medical and surgical treatment options of each are discussed.

Abstract
BACKGROUND Chronic postoperative inguinal pain (CPIP) is the most common long-term complication of inguinal hernia repair. As such procedures are routinely performed, CPIP can be considered a significant burden to global health care. Therefore, adequate preventative measures relevant to surgical practice are investigated. However, as no gold standard research approach is currently available, study and outcome measures differ between studies. The current review aims to provide a qualitative analysis of the literature to seek out if outcomes of CPIP are valid and comparable, facilitating recommendations on the best approach to preventing CPIP. METHODS A systematic review of recent studies investigating CPIP was performed, comprising studies published in 2007-2015. Study designs were analyzed regarding the CPIP definitions applied, the use of validated instruments, the availability of a baseline score, and the existence of a minimal follow-up of 12 months. RESULTS Eighty eligible studies were included. In 48 studies, 22 different definitions of CPIP were identified, of which the definition provided by the International Association for the Study of Pain was applied most often. Of the studies included, 53 (66%) used 33 different validated instruments to quantify CPIP. There were 32 studies (40%) that assessed both pain intensity (PI) and quality of life (QOL) with validated tools, 41% and 4% had a validated assessment of only PI or QOL, respectively, and 15% lacked a validated assessment. The visual analog scale and the Short Form 36 (SF36) were most commonly used for measuring PI (73%) and QOL (19%). Assessment of CPIP was unclear in 15% of the studies included. A baseline score was assessed in 45% of the studies, and 75% had a follow-up of at least 12 months. CONCLUSION The current literature addressing CPIP after inguinal hernia repair has a variable degree of quality and lacks uniformity in outcome measures. Proper comparison of the study results to provide conclusive recommendations for preventive measures against CPIP therefore remains difficult. These findings reaffirm the need for a uniform and validated assessment with uniform reporting of outcomes to improve the burden that CPIP poses to a significant surgical patient population.

Abstract
Groin pain encompasses a number of conditions from the lower abdomen, inguinal region, proximal adductors, hip joint, upper anterior thigh and perineum. The complexity of the anatomy, the heterogeneous terminology and the overlapping symptoms of different conditions that may co-exist epitomise the challenges in diagnosis and treatment. Inguinal-related and adductor-related pain is the most common cause of groin pain and will be discussed in this article.

Abstract
Groin pain is common in athletes. Yet, there is disagreement on aetiology, pathomechanics and terminology. A plethora of terms have been employed to explain inguinal-related groin pain in athletes. Recently, at the British Hernia Society in Manchester 2012, a consensus was reached to use the term inguinal disruption based on the pathophysiology while lately the Doha agreement in 2014 defined it as inguinal-related groin pain, a clinically based taxonomy. This review article emphasizes the anatomy, pathogenesis, standard clinical assessment and imaging, and highlights the treatment options for inguinal disruption.

Abstract
BACKGROUND Injury to the greater occipital nerve (GON) during suboccipital/retrosigmoid craniectomy (SOC) has been postulated as an etiology of postoperative headaches (HAs). We hypothesized that severe postoperative HAs may be due to the division of the GON during dissection. OBJECTIVE To determine whether the GON plays an important role in the development of postoperative HAs. METHODS A retrospective review of prospectively accrued patients undergoing SOC by 1 neurosurgeon at Johns Hopkins from 1995 to 2009 was performed. A total of 280 patients were included in the study. HA was categorized into 3 groups according to the severity and impact on daily activities. Data were analyzed using a stepwise multivariate logistic regression analysis to identify independent factors associated with HA development. Patients with a history of preoperative HAs and migraine were excluded from the analysis. RESULTS In this cohort, new postoperative severe HAs at last follow-up visit were found in 19% of patients. By multivariate analysis, only GON preservation (relative risk: 1.49; 95% confidence interval: 1.00-2.34; P = 0.05) and wound infection (relative risk: 2.29; 95% confidence interval: 0.91-4.25; P = 0.07) were statistically significant. By univariate analysis, positive dependent associations included GON preservation (P < .01), reconstruction of the porus with hydroxyapatite cement (P = 0.02), and wound infection (P < 0.01). Statistically significant differences in the incidence of HA after surgery were found in patients in whom the GON was preserved compared with patients in whom the GON was divided (P = 0.035). CONCLUSION Postoperative debilitating HAs are a common complication after SOC. Although these HAs are probably multifactorial in nature, preservation of the GON during SOC is independently associated with postoperative debilitating HAs.

Abstract
BACKGROUND In the literature, chronic groin pain (i.e. lasting >3 months) occurs in about 10 % of patients who undergo inguinal hernioplasty with prosthesis; it is characterized by a broad range of symptoms, and is relative to individual perceptions of pain. In 2-5 % of cases, the painful symptomatology is so intense that it interferes with daily activities, and can be debilitating in 0.5-6 % of cases. The best known cause of inguinodynia is neuropathy, due to implication of one or more inguinal nerves (iliohypogastric, ilioinguinal, and genitofemoral nerves) into fibroblastic processes; or from nervous stimulation caused by prosthetic material on adjacent nervous trunks. Many therapeutic strategies have been proposed to treat chronic groin pain, including intra-operative prophylactic neurectomy. OBJECTIVE The purpose of our study was to perform a comparative analysis between outcomes from wide resections of inguinal nerves versus those from simple nervous section (or minimal resection). PATIENTS AND METHODS We considered 350 patients who had undergone inguinal prosthetic hernioplasty with Trabucco's technique between 2004 and 2010. Wide nervous resection (removal of nerve segments 3-8 cm in length) was performed in 180. The other 170 patients underwent simple section or minimal resection. All patients were checked 1 week, 1 month, and 1 year after surgery. RESULTS Group 1: At 1-week follow-up, 63 patients (35 %) reported no pain, 113 (63 %) reported moderate pain, and 4 (2 %) intense pain; 1 month after the procedure, 152 patients (84.4 %) reported no pain, 25 (14 %) complained of moderate pain, and 3 (1.6 %) of severe pain; 1 year after surgery, only 1 patient (0.5 %) complained of constant pain. Group 2: At 1 week follow-up, 48 patients (28 %) reported no pain, 101 (59 %) reported moderate pain, and 21 (13 %) intense pain; 1 month after the procedure, 81 patients (47.6 %) had no pain, 72 (42.4 %) complained of moderate pain, and 17 (10 %) of severe pain; 1 year after surgery, 11 patients (6.5 %) had constant pain, and two of them were re-admitted for surgery. The lower incidence of chronic pain after long nervous resection is statistically significant (0.5 vs. 6.5 %; p = 0.006); the incidence of moderate pain 1 month after operation is also lower (14 vs. 42.4 %; p < 0.0001); patients who underwent a long resection experienced faster resolution of pain symptomatology, during a month. Also noteworthy is the lower incidence of intense pain in the short and medium term (after 1 week, 13 vs. 2 %, p = 0.0005; after 1 month, 10 vs. 1.6 %, p = 0.0018). CONCLUSIONS The prophylactic wide resection of selected segments of inguinal nerves, despite the apparent paradox of greater tissue damage, appears more effective than simple section at preventing postoperative inguinodynia, given both the lower incidence and the faster resolution of painful symptomatology.

Abstract
Background Inguinal hernia is one of the most common male diseases all over the world with an incidence rate of 18-24% throughout life. Chronic inguinal pain is one of the complications that prolong return to work time. Objectives The main aim of this study was to determine the effect of ilioinguinal neurectomy on postoperative chronic pain (PCP) in patients that underwent open inguinal hernia repair via the Lichtenstein method. Materials and Methods In this randomised controlled clinical trial, male patients with unilateral inguinal hernia were randomized into two groups: 74 cases in the preserved-nerve group and 66 cases in the nerve-excised group. The method of herniorrhaphy was the classic Lichtenstein method. Pain and numbness were evaluated at 1 day, 1 week, 1 month, 6 months and 1 year after surgery via visual analogue scale (VAS) system. We used SPSS ver.16 for analysis. Results All patients were male with mean age of 39.1 years (with a range of 18 to 68 years). The follow-up rate was 100% after 1 year. Pain severity was significantly lower in nerve-excised patients at 1 day, 1week, 1 month and 6 months after surgery; but it was not significant after one year, although overall pain severity was low. Numbness was significantly higher in excised patients at all endpoints (1 day, 1month, 3 months, 6 months and one year after surgery). Conclusions Ilioinguinal nerve excision at the time of inguinal hernia repair decreased post-surgical inguinal pain, and it can be used as a routine method in herniorrhaphy.

Does nerve identification during open inguinal herniorrhaphy reduce the risk of nerve damage and persistent pain? Hernia 2012; 16:573-7.

Abstract
PURPOSE Nerve identification during open inguinal hernia herniorrhaphy has been suggested as one of the factors that may reduce the risk of development of persistent postherniorrhaphy pain. In this prospective study, we evaluated whether intraoperative inguinal nerve identification influenced the risk of development of persistent postherniorrhaphy pain, sensory dysfunction in the groin and functional ability score after open hernia repair. METHODS A total of 244 men with a primary inguinal hernia underwent open Lichtenstein repair in a high-volume hernia surgery centre, where information on inguinal nerve identification was registered during operation. Before the operation and 6 months postoperatively, functional pain-related impairment was assessed with Activities Assessment Scale and pain intensity scores with Numeric Rating Scale (NRS 0-10). Quantitative sensory testing in the groin was performed before operation and 6 months postoperatively, in order to investigate intraoperative inguinal nerve damage. RESULTS The intraoperative nerve identification rates for the iliohypogastric, ilioinguinal and genitofemoral nerves were 94.7, 97.5 and 21.3 %, respectively. Thirty-nine patients (16.0 %) had substantial pain-related functional impairment at 6 months follow-up. There was no difference in risk of development of substantial pain-related functional impairment in patients with identification compared with non-identification of the iliohypogastric nerve (P = 1.0), the ilioinguinal nerve (P = 0.59), the genitofemoral nerve (P = 0.40) or all nerves (P = 0.52). There were no differences in regard to sensory loss in the groin area or in regard to improvement in functional outcome following surgery, between patients with and without nerve identification. CONCLUSIONS Although intraoperative inguinal nerve identification should be aimed at, other factors may contribute to the risk of nerve damage and persistent pain after open groin hernia repair.

Abstract
BACKGROUND Inguinal hernia repair is a common operative procedure, but the development of chronic postoperative pain is a dreaded potential complication. The role of neurectomy in decreasing the incidence of chronic pain after inguinal hernia repair is currently unknown. Our objective was to determine whether a planned ilioinguinal nerve excision results in a decrease in the development of chronic pain experienced after inguinal hernia repair. METHODS A systematic literature review was carried out to identify studies investigating the influence of ilioinguinal nerve excision on the development of chronic pain after inguinal hernia repair. A quantitative analysis of the pooled data was carried out. RESULTS Of 6,023 abstracts reviewed, 4 high-quality, randomized-controlled trials were identified. The pooled mean difference in degree of pain at 6 months postoperatively on a 10-point scale was -0.29 (95% confidence interval: -0.48 to -0.11), favoring neurectomy to decrease the chance of developing chronic pain. Not surprisingly, those individuals undergoing neurectomy were also more likely to develop altered sensation at the same time point (odds ratio: 3.70, 95% confidence interval: 2.61-5.25). CONCLUSION A planned resection of the ilioinguinal nerve at the time of inguinal hernia repair is associated with a decrease in the incidence of chronic postoperative pain. Thus, carrying out this simple maneuver at the time of operation might decrease a major source of postoperative patient morbidity.

Abstract
Chronic Groin Pain (Inguinodynia) following inguinal hernia repair is a significant, though under-reported problem. Mild pain lasting for a few days is common following mesh inguinal hernia repair. However, moderate to severe pain persisting more than 3 mo after inguinal herniorrhaphy should be considered as pathological. The major reasons for chronic groin pain have been identified as neuropathic cause due to inguinal nerve(s) damage or non-neuropathic cause due to mesh or other related factors. The symptom complex of chronic groin pain varies from a dull ache to sharp shooting pain along the distribution of inguinal nerves. Thorough history and meticulous clinical examination should be performed to identify the exact cause of chronic groin pain, as there is no single test to confirm the aetiology behind the pain or to point out the exact nerve involved. Various studies have been performed to look at the difference in chronic groin pain rates with the use of mesh vs non-mesh repair, use of heavyweight vs lightweight mesh and mesh fixation with sutures vs glue. Though there is no convincing evidence favouring one over the other, lightweight meshes are generally preferred because of their lesser foreign body reaction and better tolerance by the patients. Identification of all three nerves has been shown to be an important factor in reducing chronic groin pain, though there are no well conducted randomised studies to recommend the benefits of nerve excision vs preservation. Both non-surgical and surgical options have been tried for chronic groin pain, with their consequent risks of analgesic side-effects, recurrent pain, recurrent hernia and significant sensory loss. By far the best treatment for chronic groin pain is to avoid bestowing this on the patient by careful intra-operative handling of inguinal structures and better patient counselling pre- and post-herniorraphy.

Abstract
Proper anesthesia and knowledge of the anatomical location of the iliohypogastric and ilioinguinal nerves is important during hernia repair and other surgical procedures. Surgical complications have also implicated these nerves, emphasizing the importance of the development of a clear topographical map for use in their identification. The aim of this study was to explore anatomical variations in the iliohypogastric and ilioinguinal nerves and relate this information to clinical situations. One hundred adult formalin fixed cadavers were dissected resulting in 200 iliohypogastric and ilioinguinal nerve specimens. Each nerve was analyzed for spinal nerve contribution and classified accordingly. All nerves were documented where they entered the abdominal wall with this point being measured in relation to the anterior superior iliac spine (ASIS). The linear course of each nerve was followed, and its lateral distance from the midline at termination was measured. The ilioinguinal nerve originated from L1 in 130 specimens (65%), from T12 and L1 in 28 (14%), from L1 and L2 in 22 (11%), and from L2 and L3 in 20 (10%). The nerve entered the abdominal wall 2.8 ± 1.1 cm medial and 4 ± 1.2 cm inferior to the ASIS and terminated 3 ± 0.5 cm lateral to the midline. The iliohypogastric nerve originated from T12 on 14 sides (7%), from T12 and L1 in 28 (14%), from L1 in 20 (10%), and from T11 and T12 in 12 (6%). The nerve entered the abdominal wall 2.8 ± 1.3 cm medial and 1.4 ± 1.2 cm inferior to the ASIS and terminated 4 ± 1.3 cm lateral to the midline. For both nerves, the distance between the ASIS and the midline was 12.2 ± 1.1 cm. To reduce nerve damage and provide sufficient anesthetic for nerve block during surgical procedures, the precise anatomical location and spinal nerve contributions of the iliohypogastric and ilioinguinal nerves need to be considered.

Abstract
We conducted a randomized clinical trial on the impact of prophylactic ilioinguinal nerve excision (INE) on neuralgia, hypoesthesia, and analgesia requirement after open herniorrhaphy as well as on sustainability of a selective approach. Ninety-seven consecutive patients undergoing a Lichtenstein procedure were treated with INE (n = 45) or preservation (NP) (n = 52). Impact of patients’ age, gender, type of anesthesia, and hernia on outcomes was also evaluated by logistic regression analysis (LRA). Patients receiving INE reported less pain on postoperative days (POD) 1 and 7 and at 1 month and required less analgesia on POD 1. Overall younger patients (40 years old or younger) had more postoperative discomfort at LRA. Pain intensity was similar at 6 and 12 months after INE or NP: moderate to severe pain in 4.4 versus 11.5 per cent ( P = 0.279) and 4.4 versus 9.6 per cent ( P = 0.445), respectively. Hypoesthesia was more frequent after INE on POD 1 and 7:68.9 and 53.3 per cent versus 13.5 and 9.6 per cent, respectively ( P < 0.0001), but no longer at 1 month: 11.1 versus 3.8 per cent ( P = 0.244) as well as at 6 and 12 months (0% in both study groups). No further correlation was found by LRA. INE prevents inguinodynia up to 1 month follow-up regardless of patient variables. Moreover, the increase of hypoesthesia proved to be a short-term complication.

Abstract
INTRODUCTION All surgical procedures require an incision with a risk of nerve damage at the site of the scar or as a result of fibrotic scar tissue. The purpose of this article is to describe the management of chronic postoperative pelvic and perineal pain due to parietal somatic nerve damage. PATIENTS AND METHODS A comprehensive review of the literature was performed by searching PUBMED for articles on the management of chronic postoperative pelvic and perineal pain due to parietal somatic nerve damage. RESULTS Postoperative lesions of parietal somatic nerves (ilioinguinal, iliohypogastric, genitofemoral, pudendal, obturator, femoral) are frequent after pelvic surgery. Clinical examination of the scars (trigger zone) and detailed analysis of the topography and type of pain are essential elements in the analysis of this pain. Infiltration of local anaesthetic at the trigger point or along the nerve has a diagnostic value. Corticosteroid infiltrations and minimally invasive treatments such as pulsed radiofrequency have provided more or less lasting improvement of the symptoms. Surgical nerve release together with resection of fibrosis and removal of prosthetic material provides good long-term results. The surgical approach depends on the nerve concerned and the level of the lesion. CONCLUSION The management of chronic postoperative pelvic and perineal pain due to parietal somatic nerve damage is based on local infiltration of anaesthetics and corticosteroids. Nerve release surgery with resection of fibrosis provides the best long-term results.

Abstract
Abstract
Background
Chronic postoperative pain is a major drawback of inguinal hernia repair. This study compared the frequency of chronic pain after laparoscopic (totally extraperitoneal patch, TEP) and open (Lichtenstein) repairs.
Methods
A randomized multicentre study with 5 years' follow-up was conducted on men with a primary inguinal hernia. Chronic pain was categorized as mild, moderate or severe by blinded observers. A subgroup analysis was performed on 121 patients who experienced moderate or severe pain at any time during follow-up.
Results
Overall, 1370 of 1512 randomized patients underwent surgery, 665 in the TEP and 705 in the Lichtenstein group. The total incidence of chronic pain was 11·0 versus 21·7 per cent at 1 year, 11·0 versus 24·8 per cent at 2 years, 9·9 versus 20·2 per cent at 3 years and 9·4 versus 18·8 per cent at 5 years in the TEP and Lichtenstein groups respectively (P < 0·001). After 5 years, 1·9 per cent of patients in the TEP and 3·5 per cent in the Lichtenstein group reported moderate or severe pain (P = 0·092). Of the 121 patients, 72 (59·5 per cent) no longer reported pain a median of 9·4 (range 6·7–10·8) years after operation.
Conclusion
Five years after surgery only a small proportion of patients still report moderate to severe chronic pain. Laparoscopic inguinal hernia repair leads to less chronic pain than open repair. Registration number: NCT00568269 (http://www.clinicaltrials.gov).

Smeds S, Löfström L, Eriksson O. Influence of nerve identification and the resection of nerves 'at risk' on postoperative pain in open inguinal hernia repair. Hernia 2010; 14:265-70. [PMID: 20145966 DOI: 10.1007/s10029-010-0632-9] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2009] [Accepted: 01/15/2010] [Indexed: 10/19/2022]
Abstract
BACKGROUND Surgical strategy regarding nerve identification and resection in relation to chronic postoperative pain remains controversial. A central question is whether nerves in the operation field, when identified, should be preserved or resected. In the present study, the hypotheses that the identification and consequent resection of nerves 'at risk' have no influence on postoperative pain has been tested. METHODS A single-centre study was conducted in 525 patients undergoing Lichtenstein hernioplasty. One surgeon (364 operations, Group A) consequently resected nerves 'at risk' for being injured and nine surgeons (161 operations, Group B) adhered to the general routine of nerve preservation. All cases were ambulatory surgery on anaesthetised patients and the groups were similar with regard to age, body mass index (BMI) and preoperative pain. Self-reported pain at 3 months was recorded on a 10-box visual analogue scale (VAS). The identification and resection of nerves were continuously registered. Statistical calculations were performed with Fisher's exact test and ordinal logistic regression. RESULTS There was no significant difference in the number of identified nerves in the two groups of patients (iliohypogastricus, P = 0.555; ilioinguinalis, P = 0.831; genital branch, P = 0.214). However, the number of resected nerves was significantly higher in Group A for the iliohypogastric nerve, P < 0.001, but not for ilioinguinalis, P = 0.064, and genital branch, P = 0.362. Non-identification of the ilioinguinal nerve correlated to the highest level of self-reported postoperative pain at 3 months. Patients in Group A, who had nerves 'at risk' resected from the operation field, reported significantly less postoperative pain at 3 months, P = 0.007. CONCLUSION This register study confirms the importance of nerve identification. Nerve resection strategy with the consequent removal of nerves 'at risk' gives a significantly better outcome in Lichtenstein hernioplasty.

Abstract
BACKGROUND The Lichtenstein mesh hernioplasty is currently the most popular operative technique for open repair of inguinal hernia. The incidence of chronic groin pain (CGP) following this procedure is reported to be high. However, since our experience did not support this observation, this study was undertaken at our centre, to assess the incidence of CGP following Lichtenstein mesh hernioplasty. METHODS A prospective study was conducted on all patients undergoing elective hernia repair at a tertiary care teaching hospital. The patients underwent Lichtenstein mesh hernioplasty and were followed up for the primary outcome measures of development of recurrence and Chronic Groin Pain. RESULTS A total of 470 patients were enrolled for the study. Out of these 16 patients never reported for follow up after discharge from hospital. The remaining 454 patients with 510 primary inguinal hernias were included in the study. Of these 449 patients were male and 5 were female. The mean follow-up period was 14 months (range - six months to twenty four months). One patient had recurrence of hernia and CGP was reported in four patients. In all four patients CGP was mild and was well controlled with oral NSAIDS used on SOS basis. CONCLUSION The incidence of CGP in our study is 0.78% for the number of operated hernias. This is not only considerably less than what is generally reported but is also less disabling.

Abstract
The value of open inguinal herniorraphy without mesh is being lost. Mesh herniorraphy is being inappropriately used as the standard of care. The complication of inguinodynia is occurring at inappropriately high rates. Ilioinguinal neurectomy is not a simple solution.
