Abstract
INTRODUCTION Experimental data show that large-pored meshes reduce foreign body reaction, inflammation and scar bridging and thus improve mesh integration. However, clinical data on the effect of mesh porosity on the outcome of hernioplasty are limited. This study investigated the relation of pore size in polypropylene meshes to the outcome of Lichtenstein inguinal hernioplasty using data from the Herniamed registry. METHODS This analysis of data from the Herniamed registry evaluated perioperative and 1-year follow-up outcomes in patients undergoing elective, primary, unilateral Lichtenstein inguinal hernia repair using polypropylene meshes. Patients operated with a non-polypropylene mesh or a polypropylene mesh with absorbable components were excluded. Polypropylene meshes with a pore size of 1.0 × 1.0 mm or less were defined as small-pored meshes, while a pore size of more than 1.0 × 1.0 mm was considered large-pored. Unadjusted analyses and multivariable analyses were performed to investigate the relation of pore size of polypropylene meshes, patient and surgical characteristics to the outcome parameters. RESULTS Data from 22,141 patients were analyzed, of which 6853 (31%) were operated on with a small-pore polypropylene mesh and 15,288 (69%) with a large-pore polypropylene mesh. No association of mesh pore size with intraoperative, general or postoperative complications, recurrence rate or pain requiring treatment was found at 1-year follow-up. A lower risk of complication-related reoperation tended to be associated with small-pore size (p = 0.086). Furthermore, small-pore mesh repair was associated with a lower risk of pain at rest and pain on exertion at 1-year follow-up. CONCLUSION The present study could not demonstrate an advantage of large-pore polypropylene meshes for the outcome of Lichtenstein inguinal hernioplasty.

Kirov KG, Mihaylov DM, Arnaudov SS. Is the self-adhesive mesh a solution for chronic postoperative inguinal pain after TAPP: A single centre preliminary experience? J Minim Access Surg 2024; 20:216-221.

Abstract
BACKGROUND Minimally invasive surgery for groin hernia has expanded significantly over the last two decades and has demonstrated better outcomes in terms of pain and quality of life. A major contributing factor related to chronic post-operative inguinal pain (CPIP) is mesh fixation. An alternative to the standard fixation methods is the self-adhesive surgical mesh. PATIENTS AND METHODS Prospective data analysis was performed of all patients undergoing laparoscopic transabdominal pre-peritoneal (TAPP) inguinal hernia repair in a single centre for the period 1 st January, 2022-15 th December, 2022. A standardised surgical technique was used with a lightweight self-adhesive mesh without additional fixation. The analysis has encompassed early and late post-operative complications as well as the assessment of pain with an emphasis on CPIP. RESULTS The study enrolled 52 patients where a total number of 64 elective hernia repairs were performed: 92.2% ( n = 59) primary and 7.8% ( n = 5) recurrent. Fifty-one patients received post-operative follow-up: 100% at 1 month and 78.8% ( n = 41) at 3 months. The incidence of early postoperative complications was 7.7% ( n = 4): one patient developed a seroma, two patients - port site hematomas and one a transient subileus that were all managed conservatively. No patients suffered a recurrence. The average pain score according to the Visual Analogue Scale was 3.3 (0-8) at discharge, 0.6 (0-4) at 1 month and there was no incidence of CPIP after the 3 rd month. CONCLUSION Laparoscopic TAPP repair for inguinal hernia with a self-adhesive mesh is an adequate surgical technique with the potential to reduce CPIP, but more research is needed to evaluate this method.

Abstract
BACKGROUND The use of mesh is not without complications. Decreasing the mesh weight with the light-weight (LW) mesh may improve tissue growth and diminish mesh-related complications, yet, clinically, there are conflicting results regarding the influence of different weight meshes in ventral/incisional hernia repair. The aim of the present study is to compare the outcomes of different weight meshes for ventral/incisional hernia repair. METHODS The major databases (PubMed, Embase, Springer, and Cochrane Library) were searched, and all studies were published through January 1, 2022, using the keywords "heavy weight" "light weight" "mesh" "ventral hernia" "incisional hernia". All relevant articles and reference lists in these original studies were also obtained from the above databases. RESULTS Eight trials (4 randomized controlled trials, 3 prospective studies, and 1 retrospective study) containing 1844 patients were included in the present meta-analysis. The pooled results showed that there was a significantly more rate of foreign body perception in the heavy-weight mesh group compared with the LW mesh group (odds ratio = 5.02, 95% CI: 1.05, 24.06). There was no significant difference concerning hernia recurrence, seroma, hematoma, surgical site infection, reoperation rate, chronic pain, quality of life, and hospital stay among different weight mesh groups. CONCLUSION Different weight meshes showed similar clinical results in ventral/incisional hernia repair, except that, perception of foreign body was reported more frequently in the heavy-weight mesh group as compared with the LW mesh group. However, the long-term hernia recurrence with different weights of meshes needs to be reevaluated considering the relative short-term follow-up in these studies.

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.

Abstract
INTRODUCTION The rate of immediate implant-based breast reconstruction after mastectomy is increasing, and providing enough coverage for the implant is mandatory; however the choice of appropriate mesh for implant coverage is controversial. Considering the high cost and the limited availability of breast-dedicated meshes in our country, we conducted this study to investigate the consequences of using a polyvinylidene fluoride (PVDF) mesh designed for endoscopic and laparoscopic hernia repair (ENDOLAP) as a coverage for breast prostheses in breast reconstruction. MATERIALS AND METHODS A retrospective cross-sectional study was performed on data of patients who had underwent immediate implant-based breast reconstruction between 2012 and 2019. After skin sparing mastectomy and subpectoral implant insertion, the exposed lower and lateral parts were covered with the mesh. RESULTS Seventy-nine reconstructions were performed on 62 patients. The average follow-up was 31.9 months (ranges 6-102 months). Postoperative complications including small flap necrosis (3.8%), seroma (8.9%), infection (5.1%), hematoma (3.8%), malposition (1.3%), rippling (1.3%), grade two and three capsular contracture (2.5%), and chronic pain (1.3%) occurred in 19% of the operated breasts. The complication rate requiring intervention was 5.3%, and no implant loss was observed. None of the patients who received radiation developed complications. CONCLUSION ENDOLAP mesh is a cost-effective and safe option for implant coverage in immediate implant-based breast reconstruction, with an acceptable complication rate.

Abstract
BACKGROUND Inguinal hernia repair is one of the most common operations performed worldwide with most of the burden of these occurring in low- or middle-income countries (LMICs). There has been much research investigating the most effective method of hernia repair in resource-rich countries, however very little has been done to determine the most cost-beneficial method of hernia repair in LMICs. METHODS A systematic review of the English literature through PubMed and Scopus was conducted according to the PRISMA statement. RESULTS Twenty-eight studies met the inclusion criteria of which 17 were randomised controlled trials and 11 were systematic reviews. Three areas of investigation were established from the literature search, namely operative method and type of mesh used (where applicable). Open-mesh procedures were shown to be less costly and have shorter operative times than laparoscopic methods. People who underwent laparoscopic hernia repair regularly returned to normal activities earlier than those who had open-mesh procedures. However, there was no other difference in complication rates between these two methods. Recent investigations have revealed that sterilised synthetic mosquito net was similar to hernia-specific meshes whilst significantly reducing cost. CONCLUSION We postulate that the most cost-beneficial method of hernia repair for implementation in LMICs is using open-mesh procedures with sterilised mosquito net under local anaesthetic. Further cost-benefit research is required in this area.

Abstract
OBJECTIVE This meta-analysis and trial sequential analysis aims to provide an update on the available randomized controlled trials (RCTs) and recommendations on using lightweight mesh (LWM) or heavyweight mesh (HWM) in laparo-endoscopic inguinal hernia repair. BACKGROUND LWM might reduce chronic pain through improved mesh flexibility and less fibrosis formation. However, in laparo-endoscopic repair chronic pain is already rare and LWM raise concerns of higher recurrence rates. METHODS A literature search was conducted in May 2019 in MEDLINE, Embase, and the Cochrane library for RCTs that compared lightweight (≤50 g/m2) and heavyweight (>70 g/m2) mesh in patients undergoing laparo-endoscopic surgery for uncomplicated inguinal hernias. Outcomes were recurrences, chronic pain, and foreign-body sensation. The level of evidence was assessed using GRADE. Risk ratios (RR) and 95% confidence intervals (CI) were calculated by random effect meta-analyses. Trial-sequential-analyses were subsequently performed. RESULTS Twelve RCTs, encompassing 2909 patients (LWM 1490 vs HWM 1419), were included. The follow-up range was 3 to 60 months. Using LWM increased the recurrence risk (LWM 32/1571, HWM 13/1508; RR 2.21; CI 1.14-4.31), especially in nonfixated mesh direct repairs (LWM 13/180, HWM 1/171; RR 7.27; CI 1.33-39.73) and/or large hernia defects. No difference was determined regarding any pain (LWM 123/1362, HWM 127/1277; RR 0.79; CI 0.52-1.20), severe pain (LWM 3/1226, HWM 9/1079; RR 0.38; CI 0.11-1.35), and foreign-body sensation (LWM 100/1074, HWM 103/913; RR 0.94; CI 0.73-1.20). CONCLUSION HWM should be used in laparo-endoscopic repairs of direct or large inguinal hernias to reduce recurrence rates. LWM provide no benefit in indirect hernias.

Polytetrafluoroethylene versus polypropylene mesh during laparoscopic totally extraperitoneal (TEP) repair of inguinal hernia: short- and long-term results of a double-blind clinical randomized controlled trial. Hernia 2020; 24:1011-1018. [PMID: 32350735 DOI: 10.1007/s10029-020-02200-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Accepted: 04/19/2020] [Indexed: 12/22/2022]
Abstract
PURPOSE Aim of the study is to compare macroporous (> 1 mm2) polytetrafluoroethylene mesh (LP-PTFE) versus microporous (< 1 mm2) polypropylene mesh (SP-PPL) in terms of postoperative acute and chronic discomfort and pain, difficulty in mesh handling and long-term recurrence rate. METHODS Fifty-two patients with bilateral hernia were enrolled in this double-blind randomized controlled trial (NCT02023203). Each hernia, in the same patient, was randomized to implant LP-PTFE or SP-PPL mesh during totally extraperitoneal laparoscopic hernia repair. Patients were followed at 7 days, 1, 3, 6, 12 and 60 months after surgery. Visual analog scale (VAS) score was employed to evaluate the outcomes. Student's t test was used in case of normally distributed continuous variables, while the nonparametric Mann-Whitney U test was used in case of not normally distributed variables. Chi square test was used for analysis of categorical variables. RESULTS Median VAS discomfort score with SP-PPL was significantly higher than LP-PTFE at 1 and 3 months after surgery (p = 0.003 in both cases). LP-PTFE showed significantly lower median score than SP-PPL at 7 days after surgery (p = 0.025) regarding pain at movement. Testicular pain was lower in case of LP-PTFE than SP-PPL at 7 days, 1 and 3 months after surgery (p = 0.005, p = 0.004 and p = 0.004, respectively). LP-PTFE was significantly more difficult to handle (p = 0.001). At 60 months, one recurrence was observed in the LP-PTFE group (p = 1.0000). CONCLUSIONS LP-PTFE has less postoperative discomfort and pain up to 3 months after surgery, without differences after that period, although it shows more difficulty in handling and recurrences occur even if not statistically significant.

Abstract
INTRODUCTION Convalescence after hernia repair is one of the main focuses for hernia surgeons. We analyzed our prospectively collected data to identify possible predictive factors for post-operative acute and chronic pain. MATERIALS AND METHODS We prospectively collected the demographic data and peri-operative findings. Post-operative acute pain was evaluated with Visual Analog Pain Scale. The chronic pain (pain persists for > 6 months since operation) was also recorded. RESULTS From June 2008 to August 2018, there were 807 patients with 1029 sites of inguinal hernia enrolled in our analysis. Pain before operation was associated with the severity of acute pain on OP (operation) day, POD 1 (post-operative day 1), and POD 7 (post-operative day 7). Younger patients had significantly higher post-operative acute pain on OP day, POD 1, and POD 7. The staple mesh fixation method resulted in a higher pain score at OP day and POD 1. The predictive factors for chronic pain were sex (female), young age (< 65 years), having no past history of hypertension, pain before operation, and mesh material. CONCLUSION A younger age and inguinal pain before operation were the main predictive factors for higher post-operative pain. Younger patients, females, having inguinal pain before surgery, and using heavy weight mesh have a higher risk of chronic pain.

Abstract
OBJECTIVE Laparoscopic totally extraperitoneal (TEP) hernia repair has become increasingly widespread. Faster recovery than conventional open methods shortens the return to work. Polypropylene (PP) mesh is still in use in hernia surgery because it is an inexpensive and easily accessible patch. The post-operative chronic pain and foreign body sensation are the disadvantages of these PP patches. Poly-L-lactic acid and polypropylene (PLLA) were used in this study because of the good biocompatibility and low tissue inflammation response. We compared the early clinical outcomes of PP patch and PLLA patches. METHODS Between January 2013 and April, 2018,469 patients with inguinal hernia underwent TEP procedure. Patients were divided into two groups. PP mesh (n=211) in group 1, PLLA mesh (n=258) in group 2. Patients were compared regarding age, gender, hernia side, ASA scores, the duration of operation, pain, time to return to work, the sensation of foreign body, seroma and hematoma. RESULTS A total of 469 patients were analyzed retrospectively (426 male, 43 female). The mean age was 52.23±13.66 years. The operative times of the patients were 40.92±8.9 minutes in group 1, and 38.82±8.5 minutes in group 2 (p<0.05). The time to return to work was 10.2±1.47 days in Group 1 and 8.4±1.0 days in Group 2 (p<0.05). Visual Analog Scale (VAS) in group 2 was lower than in group 1 (p<0.005). In group 2, the feeling of the organic body decreased in the early and late period (p<0.005). Seroma and hematoma were less in Group 2 than in Group 1 (p<0.005). The mean follow-up period of the patients was 18 (3-63) months, two patients in Group 1, two patients in Group 2 recurred. CONCLUSION The PLLA patch used in the TEP method is thought to be a herniated patch that can be safely used because of its ease of application and less postoperative complication rates and more rapid return to work.

Abstract
BACKGROUND Laparoscopic groin hernia repair is an increasingly common procedure with benefits of reduced post-operative pain and infection. Post-operative chronic pain remains an ongoing concern in about 10% of patients. Parietex ProGrip™, a polyester self-gripping mesh, has a theoretical benefit of avoiding tacks for mesh-fixation. This case series reflects our long-term experience of this technique. METHODS We conducted a retrospective case series from November 2011 to December 2017. Patients were identified through an operative Medicare Benefits Schedule item number search. Clinical documentation was reviewed with length of stay, mesh infection, chronic pain, recurrence and re-operation as primary data points. RESULTS A total of 514 patients underwent 780 laparoscopic inguinal hernia repairs with self-gripping polyester mesh during this period. There were 53 female (10.3%) and 461 male patients (89.7%). Unilateral hernia repair was performed in 248 patients (48.2%) and bilateral repair in 266 patients (51.8%). Almost all repairs (779, 99.8%) were primary hernias. There were no mesh infections. Four recurrences were noted (0.51%) and three of these subsequently underwent open redo-hernia repairs (0.38%). Post-operative follow-up was up to 4.4 years. CONCLUSIONS Our series of laparoscopic groin hernia repair with self-gripping mesh demonstrate this is a safe and reliable mesh and effective technique with low recurrence rates.

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.

Köckerling F. TEP for elective primary unilateral inguinal hernia repair in men: what do we know? Hernia 2019; 23:439-459.

Abstract
INTRODUCTION Based on the new international guidelines for groin hernia management, there is no one surgical technique that is suited to all patient characteristics and diagnostic findings. Therefore, a tailored approach should be used. Here, a distinction must be made between primary unilateral inguinal hernia in men and in women, bilateral inguinal hernia, scrotal inguinal hernia, inguinal hernia following pelvic and lower abdominal procedures, patients with severe cardiopulmonary complications, recurrent inguinal hernias and incarcerated inguinal and femoral hernias. This paper now explores the relevant studies on TEP for elective primary unilateral inguinal hernia in men, which constitutes the most common indication for repair. MATERIAL A systematic search of the available literature was performed in February 2019 using Medline, PubMed, Scopus, Embase, Springer Link and the Cochrane Library. Only meta-analyses, systematic reviews, RCTs and comparative registry studies were considered. 117 publications were identified as relevant. RESULTS RCTs and comparative registry analyses demonstrated the advantages of TEP with regard to postoperative complications, complication-related reoperations, and postoperative and chronic pain compared with Lichtenstein repair for elective primary unilateral inguinal hernia repair in men. No relevant differences were found compared with TAPP. Mesh fixation is not needed in TEP, but heavyweight meshes result in a lower recurrence rate. Extraperitoneal bupivacaine analgesia vs placebo does not demonstrate any advantages, but drainage is advantageous for seroma prophylaxis. The risk of chronic pain is negatively influenced by small defects, younger patient age, preoperative pain, higher BMI, postoperative complications, higher ASA score and risk factors. CONCLUSION For the subgroup of elective primary unilateral inguinal hernia in men, accounting for a proportion of less than 50% of the total collective, advantages were identified for TEP compared with open Lichtenstein repair but not versus TAPP.

Abstract
INTRODUCTION Tension-free hernia repair has been regarded as a gold standard treatment for selected inguinal hernias, but the use of prosthetic mesh in acute incarcerated inguinal hernias is controversial. Our study focused on evaluating the safety and efficacy of the prosthetic mesh repair for emergency cases. METHODS Patients with acute incarcerated inguinal hernias who underwent emergency prosthetic mesh repair during 2009 to 2014 at our department were included. Patient characteristics, operative approaches and results, and complications were retrospectively analyzed. RESULTS A total of 167 patients were included in our study. One hundred and twenty-two patients underwent open surgery while the remaining 45 patients underwent transabdominal preperitoneal laparoscopic approach. The hernia was indirect inguinal in 133 patients (79.6%), direct inguinal in 15 patients (9.0%), and femoral in 19 patients (11.4%). The overall wound infection rate of these patients was 3%. Nonviable intestinal resection was performed in 25 patients (8.4%), only 2 of whom underwent wound infection. Another 3 patients who developed wound infection had viable hernia content. There was no mesh-related infection. There was no statistically significant difference in wound infection rates between patients with viable hernia contents and those with nonviable contents ( P < .05). CONCLUSION The use of the prosthetic mesh in the treatment of acute incarcerated inguinal hernia is safe and effective. Nonviable intestinal resection cannot be regarded as a contradiction of the mesh repair.

Abstract
INTRODUCTION Lightweight (LW) polypropylene (PP) meshes better adapt to host tissue, causing less fibrosis and inflammatory responses than high-density meshes. Mesh fixation using tissue adhesives (TA) that replace conventional sutures may improve the process of hernia repair and tissue trauma. This preclinical study compares the behavior of different cyanoacrylate-based adhesives in the fixation of LW-PP meshes for hernia repair. METHODS Partial abdominal wall defects were repaired using LW-PP Optilene meshes in New Zealand rabbits. The following groups were established according to the mesh fixation method: Suture (control), Glubran 2 (n-butyl), Ifabond (n-hexyl), SafetySeal (n-butyl) and Evobond (n-octyl). At 14, 90 and 180 days after surgery, the recovered implants were examined to assess the host tissue integration, the macrophage response and the biomechanical strength. RESULTS All the groups showed optimal host tissue incorporation regardless of the fixation procedure. Significantly increased levels of collagen 1 and collagen 3 gene expression (p<0.001) were observed at 14 days compared to the medium- and long-term durations, where the Suture and Glubran groups showed the highest expression of collagen 1. All the adhesives increased the macrophage reaction (p<0.001) compared to sutures at all implant times. Maximal macrophage response was observed in the short-term Glubran group (p<0.01) compared to the rest of the groups. Although SafetySeal and Evobond did not reach the biomechanical resistance of sutures at 14 days, all the adhesives did reach this level in the medium- to long-term periods, providing significantly higher resistance (p<0.05). CONCLUSIONS All the cyanoacrylates, despite inducing a significantly increased macrophage response versus sutures, showed optimal host tissue integration and long-term mechanical behavior; thus, they might be good choices for LW-PP mesh hernia repairs.

Abstract
Introduction: This study looks at the outcome of 352 patients that underwent the "Manchester groin repair" in the period from 2007 to 2016. The effect of laterality on chronic groin pain and the reduction of pain scores post-surgery are evaluated as well as the rate of hernia recurrence for the inguinal hernia repairs. Methods: The "Manchester groin repair" is a modification of a laparoscopic totally extra-peritoneal approach with fibrin sealant mesh fixation. Data were collected prospectively. In addition to demographic data and the European Hernia Society classification grading of each hernia, pain scores were assessed prior to surgery and at 4-6 weeks post-operatively using a ten-point visual analog pain scale. Data were collected on a bespoke database and differences between time-points analyzed by non-parametric Wilcoxon signed rank tests with Kruskal-Wallis rank sum test for three-group comparisons. Significance was at the P < 0.05 level. The study was undertaken as an institutional audit. Results: Three hundred and fifty two patients underwent TEP repair as per the "Manchester Groin Repair" modification during the period of interest with a median follow-up period of 109.5 (IQR 57.0-318.5) weeks. Of these 274 (77.8%) were for the repair of true hernias and 78 (22.2%) were for inguinal disruptions. All inguinal hernia repairs patients were evaluated (254 m, 20 f); median [interquartile range] age 50 (39-65) years. There were 75 right inguinal hernias (27.4%), 39 Left inguinal hernias (14.2%), and 160 bilateral inguinal hernias (58.4%), giving a total of 434 hernia repairs. During follow-up there were 6 recurrences (1.4%).Of the 274 patients evaluated, 145 (52.9%) had both pre and post-operative pain scores available. Median pre-operative pain score was 5 [IQR 4-7]. Median post-operative pain score was 1 [IQR 1-2]. This difference was significant (P < 0.001). Pre-operative pain scores were higher for those with a bilateral hernia (median 6 vs. 5 and 4, respectively; P = 0.005), but there was no difference in post-operative scores (P = 0.347). One patient (0.3%) presented with chronic groin pain (pain after 3 months). Conclusion: This study demonstrates that the "Manchester groin repair" provides an excellent repair with a low rate of recurrence and low incidence of chronic pain. Longer-term evaluation and larger patient series will add to the understanding of the role of this procedure in groin hernia repair.

Abstract
PURPOSE Recurrence after laparoscopic inguinal herniorrhaphy is poorly understood. Reports suggest that up to 13% of all inguinal herniorrhaphies worldwide, irrespective of the approach, are repaired for recurrence. We aim to review the risk factors responsible for these recurrences in laparoscopic mesh techniques. METHODS A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified English language, peer reviewed articles on the causes of recurrence following laparoscopic mesh inguinal herniorrhaphy published between 1990 and 2018. The search terms included 'Laparoscopic methods', 'Inguinal hernia; Mesh repair', 'Recurrence', 'Causes', 'Humans'. RESULTS The literature revealed several contributing risk factors that were responsible for recurrence following laparoscopic mesh inguinal herniorrhaphy. These included modifiable and non-modifiable risk factors related to patient and surgical techniques. CONCLUSIONS Recurrence can occur at any stage following inguinal hernia surgery. Patients' risk factors such as higher BMI, smoking, diabetes and postoperative surgical site infections increase the risk of recurrence and can be modified. Amongst the surgical factors, surgeon's experience, larger mesh with better tissue overlap and careful surgical techniques to reduce the incidence of seroma or hematoma help reduce the recurrence rate. Other factors including type of mesh and fixation of mesh have not shown any difference in the incidence of recurrence. It is hoped that future randomized controlled trials will address some of these issues and initiate preoperative management strategies to modify some of these risk factors to lower the risk of recurrence following laparoscopic inguinal herniorrhaphy.

Lower recurrence rate with heavyweight mesh compared to lightweight mesh in laparoscopic totally extra-peritoneal (TEP) repair of groin hernia: a nationwide population-based register study. Hernia 2018; 22:989-997. [PMID: 30168009 PMCID: PMC6245119 DOI: 10.1007/s10029-018-1809-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Accepted: 08/18/2018] [Indexed: 12/03/2022]
Abstract
Purpose Lightweight meshes (LWM) have shown benefits compared to heavyweight meshes (HWM) in terms of less postoperative pain and stiffness in open inguinal hernia repair. It appears to have similar advantages also in TEP, but concerns exist if it may be associated with higher recurrence rates. The aim of the study was to compare reoperation rate for recurrence of LWM to HWM in laparoscopic totally extra-peritoneal (TEP) repair. Methods All groin hernias operated on with TEP between 1 January 2005 and 31 December 2013 at surgical units participating in The Swedish Hernia Register were eligible. Data included clinically important hernia variables. Primary endpoint was reoperation for recurrence. Median follow-up time was 6.1 years (0–11.5) with minimum 2.5 years postoperatively. Results In total, 13,839 repairs were included for statistical analysis and 491 were re-operated for recurrence. Multivariate analysis demonstrated significantly increased risk of reoperation for recurrence in LWM 4.0% (HR 1.56, P < 0.001) compared to HWM 3.2%. This was most evident in direct hernias (HR 1.75, P < 0.001) and in hernia repairs with a defect > 3 cm (HR 1.54, P < 0.021). The risk of recurrence with use of LWM in indirect hernias and in hernia repairs with a defect < 1.5 cm was more comparable to HWM. Conclusions Lightweight meshes were associated with an increased risk of reoperation for recurrence compared to HWM. While direct hernias and larger hernia defects may benefit from HWM to avoid increased recurrence rates, LWM is recommended to be used in indirect and smaller hernia defects in TEP repair.

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.

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
Introduction Chronic postoperative inguinal pain (CPIP) is the most common complication after inguinal hernia operation. Eighteen percent (range, 0.7%-75%) of patients suffered from CPIP after open inguinal hernia repair and 6% (range, 1%-16%) reported CPIP after laparoendoscopic groin hernia repair. The incidence of clinically significant CPIP with impact on daily activities ranged between 10% and 12%. Debilitating CPIP with severe impact on normal daily activities or work was reported in 0.5%-6% of the cases. Materials and methods PubMed, Medline, Embase, and the Cochrane Database were searched for studies on risk factors for chronic pain after open and endoscopic hernia repair. A systematic review of the literature was conducted using the grading of recommendations, assessment, development, and evaluations (GRADE) methodology. Results Risk factors for CPIP with strong evidence include female gender, young age, high intensity of preoperative pain, high early postoperative pain intensity, history of chronic pain other than CPIP, operation for a recurrent hernia, and open repair technique. Risk factors for CPIP with moderate evidence include postoperative complications, neurolysis, and preservation of the ilioinguinal nerve in Lichtenstein repair. Risk factors for CPIP with low evidence include genetic predisposition (DQB1*03:02 HLA haplotype), lower preoperative optimism, high pain intensity to tonic heat stimulation, inadequate suture/staple/clip mesh fixation, ignorance of the inguinal nerves, less experienced surgeon, sensory dysfunction in the groin, and worker's compensation. Conclusion Detailed knowledge of the risk factors, meticulous operative technique with profound knowledge of the anatomy, proper nerve identification and handling, optimization of prosthetic materials, and careful fixation are of utmost importance for the prevention of CPIP.

Abstract
To investigate the efficacy, key technical points, and complication management of the transabdominal preperitoneal (TAPP) approach for incarcerated inguinal hernia repair. Seventy-three patients with incarcerated inguinal hernias underwent TAPP surgery in our department between Jan 2010 and Dec 2015. A retrospective review was performed by analyzing the perioperative data from these patients. The operation was successfully completed in all 73 patients. Operation time was 54.0 ± 18.8 minutes (range, 35-100 minutes). Length of stay was 3.9 ± 1.1 days (range, 3-9 days). There was 1 case of incisional infection, 32 cases of seroma, and 3 cases of postoperative pain during follow-up. All patients recovered after the appropriate treatment. No recurrence or fistula was observed. The TAPP approach represents a safe and effective technique for incarcerated inguinal hernia repair because of its potential in assessment of hernia content and decreasing incisional infection rate. However, it requires experienced surgeons to ensure safety with special attention paid to the key technical points as well as complication management.

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
BACKGROUND The aim of our study was to compare chronic groin pain and quality of life (QOL) after laparoscopic lightweight (LW) and heavyweight (HW) mesh repair for groin hernia. MATERIALS AND METHODS One hundred and forty adult patients with uncomplicated inguinal hernia were randomised into HW mesh group or LW mesh group. Return to activity, chronic groin pain and recurrence rates were assessed. Short form-36 v2 health survey was used for QOL analysis. RESULTS One hundred and thirty-one completed follow-up of 3 months, 66 in HW mesh group and 65 in LW mesh group. Early post-operative convalescence was better in LW mesh group in terms of early return to walking (P = 0.01) and driving (P = 0.05). The incidence of early post-operative pain, chronic groin pain and QOL and recurrences were comparable. CONCLUSION Outcomes following laparoscopic inguinal hernia repair using HW and LW mesh are comparable in the short-term as well as long-term.

Abstract
BACKGROUND Duration of convalescence after inguinal hernia repair is of major socio-economic interest and an often reported outcome measure. The primary aim was to perform a critical analysis of duration of convalescence from work and activity and secondary to identify risk factors for unexpected prolonged convalescence after laparoscopic inguinal hernia repair. METHODS A qualitative systematic review was conducted. PubMed, Embase and the Cochrane database were searched for trials reporting convalescence after laparoscopic inguinal hernia repair in the period from January 1990 to January 2016. Furthermore, snowball search was performed in reference lists of identified articles. Randomized controlled trials and prospective comparative or non-comparative trials of high quality were included. Trials with ≥100 patients, >18 years of age and manuscripts in English were included. Scoring systems were used for assessment of quality. RESULTS The literature search identified 1039 papers. Thirty-four trials were included in the final review including 14,273 patients. There was overall a large variation in duration of convalescence. Trials using non-restrictive recommendations of 1-2 days or "as soon as possible to return to all activities" reported overall a shorter duration of convalescence compared with trials not using recommendations for convalescence. Strenuous physical activity at work, strenuous leisure activity and patients with expectations of a prolonged period of convalescence may be risk factors for prolonged convalescence extending more than a few days after laparoscopic inguinal hernia repair. CONCLUSIONS Patients should be recommended a duration of 1-2 days of convalescence after laparoscopic inguinal hernia repair. Short and non-restrictive recommendations may reduce duration of convalescence without increasing risk of pain, complications or recurrence rate.

Abstract
Surgical mesh has become an indispensable tool in hernia repair to improve outcomes and reduce costs; however, efforts are constantly being undertaken in mesh development to overcome postoperative complications. Common complications include infection, pain, adhesions, mesh extrusion and hernia recurrence. Reducing the complications of mesh implantation is of utmost importance given that hernias occur in hundreds of thousands of patients per year in the United States. In the present review, the authors present the different types of hernia meshes, discuss the key properties of mesh design, and demonstrate how each design element affects performance and complications. The present article will provide a basis for surgeons to understand which mesh to choose for patient care and why, and will explain the important technological aspects that will continue to evolve over the ensuing years.

Abstract
BACKGROUND Inguinal hernias are common in elderly males. We addressed outcome following totally extraperitoneal (TEP) hernia repair in patients older than 70 years. METHODS We prospectively collected data of patients >70 years with a unilateral or bilateral inguinal hernia operated in our hospital between January 2005 and January 2010 using the TEP technique. RESULTS A total of 429 patients underwent TEP hernia repair under general anaesthesia, mostly men (n = 405; 94.4%). Median age was 74 years (range 70-89). The mean pre-operative pain score was 3.7 (SD ± 2.5). Ninety-four percent of patients had an ASA score of 1 or 2. Three hundred thirty-six patients underwent a unilateral repair (78%). The conversion rate to an anterior procedure was 0.7 % (n = 3). In 8 patients (1.9%), intra-operative complications occurred, and the postoperative course was complicated in 3 patients (0.7 %). Severe complications attributable to the endoscopic approach occurred in 6 patients (1.4%): a bladder injury (n = 5) and a trocar-induced bowel perforation (n = 1). The mean postoperative pain score after 6 weeks was 1.6 (SD ± 1.2). Patients were able to resume their daily activities after a median of 7 days (range 1-42). CONCLUSION Totally, extraperitoneal endoscopic inguinal hernia repair in elderly patients is associated with low overall complication rates and a fast recovery. In a small proportion of patients, severe complications occur attributable to the endoscopic approach.

Abstract
BACKGROUND The incidence of chronic pain after endoscopic hernia repair varies between 1 and 16 %. Studies regarding the course of pain in time after the operation are scarce. METHODS 473 male patients ≥18 years of age, scheduled for totally extraperitoneal (TEP) hernia repair (Prolene® mesh) between March 2010 and August 2012 were requested to record pain symptoms preoperative, and 1 day, 1 week, 6 weeks, 3 months and 1 year postoperatively and visit the outpatient department 3 months and 1 year postoperatively for a standardized interview and physical examination. RESULTS Preoperatively, 25 % (n = 114) of the patients had moderate-to-severe pain (NRS 4-10). Six weeks postoperatively, 3 % (n = 12) of the patients still experienced moderate-to-severe pain. Three months after TEP, only 3 patients (0.6 %) had moderate-to-severe pain, while 83 patients (18 %) experienced mild pain. One year after TEP, 39 patients experienced mild pain (8 %) and 3 patients moderate pain (0.7 %), no patients experienced severe pain after 1 year. Patients with moderate-to-severe pain preoperatively had a higher risk of pain persisting until 3 months and 1 year postoperatively (p = 0.03). In most patients who had pain 3 months postoperatively and were pain-free 1 year after TEP, pain 'faded out' at 4-6 months postoperatively. Two patients had a not-painful recurrent hernia, diagnosed 2 and 5 months after TEP repair. CONCLUSION Moderate-to-severe pain after TEP hernia repair is self-limiting, with less than 1 % of the patients reporting moderate pain 1 year postoperatively.

Abstract
BACKGROUND Hernioplasty is one of the most frequent surgeries in the UK. Light-weight mesh (LWM) has the potential to reduce chronic groin pain but its cost-effectiveness compared with heavy-weight mesh (HWM) is unknown. OBJECTIVE Our objective was to conduct a cost-utility analysis between laparoscopic hernioplasty with HWM and LWM for unilateral inguinal hernias. METHODS A Markov model simulated costs and health outcomes over a period of 1 year (2012) from the societal and National Health Service (NHS) perspective (England). The main outcome was cost per quality-adjusted life-year (QALY) gained. Surgery results were gleaned from the randomized control trial by Bittner et al. Other input parameters were drawn from the literature and public sources of the NHS. RESULTS From the societal perspective, LWM induces lower incremental costs (-£88.85) than HWM but yields a slightly smaller incremental effect (-0.00094 QALYs). The deterministic incremental cost-effectiveness ratio (ICER) for HWM compared with LWM amounts to £94,899 per QALY, while the probabilistic ICER is £118,750 (95 % confidence interval [CI] £57,603-180,920). Owing to the withdrawal of productivity losses from the NHS perspective, LWM causes higher incremental costs (£13.09) and an inferior incremental effect (-0.00093), resulting in a dominance of HWM over LWM (ICER 95 % CI -£12,382 to -£21,590). CONCLUSIONS There is no support for the adoption of LWM as standard treatment from an NHS perspective. However, given the small differences between HWM and LWM, LWM has at least the potential of improving patient outcomes and reducing expenditure from the societal perspective.

Abstract
Persistent postsurgical pain (PPSP) is a frequent and often disabling complication of many surgical procedures. Nerve injury-induced neuropathic pain (NeuP) has repeatedly been proposed as a major cause of PPSP. However, there is a lack of uniformity in NeuP assessment across studies, and the prevalence of NeuP may differ after various surgeries. We performed a systematic search of the PubMed, CENTRAL, and Embase databases and assessed 281 studies that investigated PPSP after 11 types of surgery. The prevalence of PPSP in each surgical group was examined. The prevalence of NeuP was determined by applying the recently published NeuP probability grading system. The prevalence of probable or definite NeuP was high in patients with persistent pain after thoracic and breast surgeries-66% and 68%, respectively. In patients with PPSP after groin hernia repair, the prevalence of NeuP was 31%, and after total hip or knee arthroplasty it was 6%. The results suggest that the prevalence of NeuP among PPSP cases differs in various types of surgery, probably depending on the likelihood of surgical iatrogenic nerve injury. Because of large methodological variability across studies, a more uniform approach is desirable in future studies for evaluating persistent postsurgical NeuP.

Transabdominal preperitoneal versus totally extraperitoneal repair of inguinal hernia: a meta-analysis of randomized studies. Am J Surg 2013; 206:245-252.e1.

Abstract
BACKGROUND The aim of the present study was to comparatively evaluate the outcomes of laparoscopic transabdominal preperitoneal inguinal hernia repair and totally extraperitoneal repair. METHODS The electronic databases of Medline, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, and a meta-analysis of randomized clinical trials was undertaken. RESULTS Seven studies comprising 516 patients with 538 inguinal hernia defects were identified. A shorter recovery time (P = .02) was found for totally extraperitoneal repair in comparison with transabdominal preperitoneal inguinal hernia repair (weighted mean difference = -.29; 95% confidence interval [CI], -.71 to .07) although the length of hospitalization (P = .89) was similar in the 2 treatment arms (weighted mean difference = .01; 95% CI, -.13 to .15). Operative morbidity (P = .004) was higher for the preperitoneal approach (odds ratio = 2.15; 95% CI, 1.29 to 3.61). No differences were found with regard to the incidence of recurrence, long-term neuralgia, and operative time. CONCLUSIONS Current evidence suggests similar operative results for endoscopic and laparoscopic inguinal hernia repair, with a trend toward higher morbidity for the preperitoneal approach. Randomized trials with a longer-term follow-up are needed in order to assess the effect of each approach on the prevention of recurrence.

Abstract
BACKGROUND A systematic analysis was conducted of randomized controlled trials (RCTs) comparing lightweight mesh (LWM) with heavyweight mesh in laparoscopic inguinal hernia repair. METHODS Data extracted from the included RCTs were analyzed according to the principles of meta-analysis. RESULTS Eleven RCTs encompassing 2,189 patients were analyzed. In a fixed-effects model, operating time, postoperative pain, and recurrence rate were statistically similar between LWM and heavyweight mesh. LWM was associated with fewer perioperative complications and a reduced risk for developing chronic groin pain. There was also a reduced risk for developing other groin symptoms, such as foreign body sensations, but it was not statistically significant. CONCLUSIONS The use of LWM for laparoscopic inguinal hernia repair is not associated with an increased risk for hernia recurrence. LWM reduces the incidence of chronic groin pain, groin stiffness, and foreign body sensations. Therefore, LWM may routinely be used in laparoscopic inguinal hernia repair. However, high-quality RCTs with longer follow-up periods are required to validate these findings.

Abstract
PURPOSE The aim of this article is to compare the outcomes of lightweight mesh and heavyweight mesh in inguinal hernia repair. METHOD A comprehensive literature search was undertaken to identify studies comparing the influence of lightweight and heavyweight meshes on inguinal hernia. RESULTS The present meta-analysis pooled the effects of outcomes of a total 5,389 patients enrolled into 16 randomized controlled trials and 5 comparative studies. Lightweight mesh repair was associated with a significant less incidence of chronic postoperative pain [OR = 0.72, 95 % CI (0.57, 0.91)] and less feeling of foreign body than heavyweight mesh repair [OR = 0.50, 95 % CI (0.37, 0.67)]. Recurrence at 12 months was marginally increased in lightweight group (p = 0.05) [RD = 0.01, 95 % CI (0.00, 0.02)]. However, statistically there was no difference in the incidence of seroma [OR = 0.80, 95 % CI (0.52, 1.23)], infection [RD = -0.00, 95 % CI (-0.01, 0.00)], and testicular atrophy [RD = 0.01, 95 % CI (-0.01, 0.02)]. CONCLUSION There was no difference regarding the incidence of seroma, infection, and testicular atrophy between lightweight mesh versus heavyweight mesh for inguinal hernia. There is a concern on the recurrence when lightweight mesh is used in large inguinal hernias. However, lightweight mesh repair do have advantages in terms of chronic postoperative pain and feeling of foreign body, and further well-structured trials with improved standardization of hernia types, operative techniques are necessary.

Abstract
BACKGROUND Reinforcement of inguinal hernia repair with prosthetic mesh is standard practice but can cause considerable pain and stiffness around the groin and affect physical functioning. This has led to various types of mesh being engineered, with a growing interest in lighter-weight mesh. Minimally invasive approaches have also significantly reduced postoperative recovery from inguinal hernia repair. The aim of this systematic review was to compare the outcomes after laparoscopic inguinal repair using new lightweight or traditional heavyweight mesh in published randomised controlled trials. METHODS Medline, Embase, trial registries, conference proceedings, and reference lists were searched for controlled trials of heavyweight versus lightweight mesh for laparoscopic repair of inguinal hernias. The primary outcomes were recurrence and chronic pain. Secondary outcomes were visual analogue pain score at 7 days postoperatively, seroma formation, and time to return to work. Risk differences were calculated for categorical outcomes and standardised mean differences for continuous outcomes. RESULTS Eight trials were included in the analysis of 1,667 hernias in 1,592 patients. Mean study follow-up was between 2 and 60 months. There was no effect on recurrence [pooled analysis risk difference 0.00 (95% CI -0.01 to 0.01), p = 0.86] or chronic pain [pooled analysis risk difference -0.02 (95% CI -0.04 to 0.00); p = 0.1]. Lightweight and heavyweight mesh repair had similar outcomes with regard to postoperative pain, seroma development, and time to return to work. CONCLUSION Both mesh options appear to result in similar long- and short-term postoperative outcomes. Further long-term analysis may guide surgeon selection of mesh weight for laparoscopic inguinal hernia repair.
