Total extraperitoneal endoscopic hernioplasty (TEP) versus Lichtenstein hernioplasty: a systematic review by updated traditional and cumulative meta-analysis of randomised-controlled trials. Hernia 2019; 23:1093-1103. [PMID: 31602585 PMCID: PMC6938473 DOI: 10.1007/s10029-019-02049-w] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Accepted: 09/04/2019] [Indexed: 01/17/2023]
Abstract
Background–purpose Totally extraperitoneal (TEP) endoscopic hernioplasty and Lichtenstein hernioplasty are the most commonly used approaches for inguinal hernia repair. However, current evidence on which is the preferred approach is inconclusive. This updated meta-analysis was conducted to track the accumulation of evidence over time. Methods Studies were identified by a systematic literature search of the EMBASE, PubMed, Cochrane Library, and Google Scholar databases. Fixed- and random-effects models were used to cumulatively assess the accumulation of evidence over time. Results The TEP cohort showed significantly higher rates of recurrences and vascular injuries compared to the Lichtenstein cohort; [Peto Odds ratio (OR) = 1.58 (1.22, 2.04), p = 0.005], [Peto OR = 2.49 (1.05, 5.88), p = 0.04], respectively. In contrast, haematoma formation rate, time to return to usual activities, and local paraesthesia were significantly lower in the TEP cohort compared to the Lichtenstein cohort; [Peto OR = 0.26 (0.16, 0.41), p ≤ 0.001], [mean difference = − 6.32 (− 8.17, − 4.48), p ≤ 0.001], [Peto OR = 0.26 (0.17, 0.40), p ≤ 0.001], respectively. Conclusions This study, which is based on randomised-controlled trials (RCTs) of high quality, showed significantly higher rates of recurrences and vascular injuries in the TEP cohort than in the Lichtenstein cohort. In contrast, rate of postoperative haematoma formation, local paraesthesia, and time to return to usual activities were significantly lower in the TEP cohort than in the Lichtenstein cohort. Future multicentre RCTs with strict adherence to the standards recommended in the Consolidated Standards of Reporting Trials guidelines will shed further light on the topic.

Köckerling F. TEP for elective primary unilateral inguinal hernia repair in men: what do we know? Hernia 2019; 23:439-459. [PMID: 31062110 PMCID: PMC6586704 DOI: 10.1007/s10029-019-01936-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Accepted: 03/26/2019] [Indexed: 01/09/2023]
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 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
Hernia repair techniques vary greatly depending upon the setting, surgeons, insurance reimbursement systems, resources, and logistical capabilities. Open mesh repair is the most frequently used technique. Choosing the best technique for inguinal hernia repair is a challenge. There is no single technique to manage every type of hernia. Today, laparoscopy and robotics are at the forefront of advanced surgical tools and offer a range of options for general surgeons who are critically evaluating new procedures. However, before using a new procedure, such as endo-laparoscopic hernia repair, surgeons often ask the rhetorical question, "Why change?" The common considerations are the availability of equipment, familiarity with the anatomy when using these techniques, operative time, cost to the patient, and the potential need to convert to an open procedure. Additionally, we are now seeing a significant shift away from surgeon-defined benefits to patient-defined benefits. As patients become more aware of their options for hernia procedures and share their experiences, more and more patients are likely to demand a particular technique. Hence, hernia surgeons should be educated on the different techniques available for inguinal hernia repair, including endo-laparoscopic procedures. In this article, we review the existing literature on the current role of endo-laparoscopic inguinal hernia repair.

Abstract
BACKGROUND Inguinal hernia repair is the most common elective procedure in general surgery. Therefore, the number of patients having complications related to inguinal hernia surgery is relatively large. The aim of this study was to compare complication profiles of inguinal open mesh (OM) hernioplasties with open non-mesh (OS) repairs and laparoscopic (LAP) repairs using retrospective nationwide registry data. METHODS The database of the Finnish Patient Insurance Centre (FPIC) was searched for complications of inguinal and femoral hernia repairs during 2002-2010. Complications of OM repairs were compared to complications of OS repairs and LAP repairs. RESULTS Over 75 % of all inguinal hernia procedures during the study period in Finland were OM hernioplasties. FPIC received 245 complication reports after OM repairs, 40 after OS repairs, and 50 after LAP repairs. Reported complications were significantly more severe after LAP and OS repairs than OM surgery (p<0.001). Visceral complications (p<0.001), deep infections (p<0.001), and deep hemorrhagic complications (p<0.001) were overrepresented in the LAP group. In the OS group, visceral complications (p<0.001), recurrences (p<0.001), and severe neuropathic pain (p<0.001) predominated. CONCLUSION LAP and OS repairs of inguinal hernia were associated with more severe complications than open surgery with mesh in this study.

Abstract
BACKGROUND Surgery for inguinal hernia continues to evolve. The most recent development in the field of surgery for inguinal hernia is the emergence of laparoscopic inguinal hernia surgery (LIHS) which is challenging the gold standard Lichtenstein's tension free mesh repair. Our centre has the largest series of LIHS from any Armed Forces hospital. The aim of this study was to analyze the short and long term outcomes at our center since its inception. METHODS Retrospective review of prospectively maintained data base of 501 LIHS done in 434 patients by a single surgeon between April 2008 and October 2013. Preoperative, intraoperative, postoperative and follow-up data was analyzed with emphasis on the recurrence rates and the incidence of inguinodynia. RESULTS 402 (92.6%) patients had primary hernias and 367 (84.6%) patients had unilateral hernias. Of the 501 repairs, 453 (90.4 %) were done totally extraperitoneal approach and 48 (9.6 %) were done by the transabdominal preperitoneal approach. The mean operative time for unilateral and bilateral repairs was 40.9 ± 11.2 and 76.2 ± 15.0 minutes, respectively. The conversion rate to open surgery was 0.6%. The intraoperative, and early and late postoperative complication rates were 1.7%, 6.2% and 3%, respectively. The incidence of chronic groin pain was 0.7% and the recurrence rate was 1.6%. The median hospital stay was 1 day (1-5 days). CONCLUSION We, in this series of over 500 repairs have demonstrated that feasibility as well as safety of LIHS at our centre with good short and long term outcomes.

Abstract
Purpose Coskun hernia repair technique has been reported to be an effective new fascia transversalis repair with its short-term follow-up results. Our aim is to determine the results of Coskun hernia repair technique and to compare it with Lichtenstein technique. Methods At this comparative retrospective study a total of 493 patients, who had groin hernia repair procedure using Coskun or Lichtenstein technique, between January 1999 and March 2010 were enrolled into the study. Patients were reached by telephone and invited to get a physical examination. Results Out of 493 groin hernia repairs, 436 (88.5%) were carried out by residents and 57 (11.5%) by attending surgeons. Lichtenstein technique was the choice in 241 patients and 252 patients underwent Coskun hernia repair technique. Groin hernia recurrence was detected in 8 patients (3.1%) in Coskun hernia repair group and 7 patients (2.9%) in Lichtenstein group. Comparison of early complication rates in Coskun group (3.9%) and Lichtenstein group (4.5%) showed no significant difference. Late complication rates were significantly higher in Lichtenstein group (1.2% vs. 4.9%). The operation time was shorter in Coskun group (44 minutes) than in Lichtenstein group (60 minutes). Subgroup of patients, whose hernia repair operations were carried out by attending surgeons, had a recurrence rate of 0% and 3.8%, in Coskun group and Lichtenstein group, respectively. Conclusion This study showed that Coskun hernia repair technique has a similar efficacy with Lichtenstein repair, on follow-up.

Abstract
Introduction Inguinal hernias have been treated traditionally with open methods of herniorrhaphy or hernioplasty. But the trends have changed in the last decade with the introduction of minimal access surgery. Methods This study was a prospective descriptive study in patients presenting to Surgery Department of B. P. Koirala Institute of Health Sciences, Dharan, Nepal with reducible inguinal hernias from January 2011 to June 2012. All patients >18 years of age presenting with inguinal hernias were given the choice of laparoscopic repair or open repair. Those who opted for laparoscopic repair were included in the study. Results There were 50 patients, age ranged from 18 to 71 years with 34 being median age at presentation. In 41 patients, totally extraperitoneal repair was attempted. Of these, 2 (4%) repairs were converted to transabdominal repair and 2 to open mesh repair (4%). In 9 patients, transabdominal repair was done. The median total hospital stay was 4 days (range 3-32 days), the mean postoperative stay was 3.38±3.14 days (range 2-23 days), average time taken for full ambulation postoperatively was 2.05±1.39 days (range 1-10 days), and median time taken to return for normal activity was 5 days (range 2-50 days). One patient developed recurrence (2%). None of the patients who had laparoscopic repair completed complained of neuralgias in the follow-up. Conclusion Laparoscopic repair of inguinal hernias could be contemplated safely both via totally extra peritoneal as well as transperitoneal route even in our setup of a developing country with modifications.

Abstract
Background: There are no published data on the outcomes of inguinal hernia repair from the Anglophone Caribbean. To the best of our knowledge, this is the first report of a series of laparoscopic inguinal hernia repairs from the region. Materials and Methods: Data was extracted from a prospectively maintained database of consecutive trans abdominal pre-peritoneal (TAPP) repairs done between June 1, 2005 and May 30, 2012. Perioperative data collected included patient demographics, hernia type, operative technique, duration of surgery, intra-operative details, morbidity, analgesia requirements, and duration of hospitalization. A telephone survey was also performed to identify late recurrences and complications. Descriptive statistics were generated using Statistical Package for Social Sciences (SPSS) Ver 12.0. Results: There were 103 consecutive TAPP procedures in 88 patients at an average age of 35.4 years ± 12.9 (standard deviation; SD) and average body mass index (BMI) of 28.9 Kg/m2 ± 2.23 (SD). The indications were bilateral (30), recurrent unilateral (24), and primary unilateral (49) inguinal hernias. The mean duration of operation was 68.5 minutes (SD ± 10.4; Range: 55-95; Median 65; Mode 65) minutes for unilateral TAPP and 89 minutes (SD ± 7.61; Range: 80-105; Median 90; Mode 90) for bilateral repairs. Post-operatively, 65/70 patients required ≤1 dose of parenteral opioid analgesia and 74 (84.1%) patients discontinued oral analgesia within 48 hours of operation. Complications were recorded in six (5.8%) cases and a recurrence in one (0.97%) case after a mean follow-up period of 3.2 years (SD ± 1.8; Range: 0.5-7). Conclusion: Laparoscopic inguinal hernia repair is a safe and effective operation in this setting.

The totally extraperitoneal method versus Lichtenstein's technique for inguinal hernia repair: a systematic review with meta-analyses and trial sequential analyses of randomized clinical trials. PLoS One 2013; 8:e52599. [PMID: 23349689 PMCID: PMC3543416 DOI: 10.1371/journal.pone.0052599] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2011] [Accepted: 11/19/2012] [Indexed: 11/26/2022] Open
Abstract
Background Lichtenstein's technique is considered the reference technique for inguinal hernia repair. Recent trials suggest that the totally extraperitoneal (TEP) technique may lead to reduced proportions of chronic pain. A systematic review evaluating the benefits and harms of the TEP compared with Lichtenstein's technique is needed. Methodology/Principal Findings The review was performed according to the ‘Cochrane Handbook for Systematic Reviews’. Searches were conducted until January 2012. Patients with primary uni- or bilateral inguinal hernias were included. Only trials randomising patients to TEP and Lichtenstein were included. Bias evaluation and trial sequential analysis (TSA) were performed. The error matrix was constructed to minimise the risk of systematic and random errors. Thirteen trials randomized 5404 patients. There was no significant effect of the TEP compared with the Lichtenstein on the number of patients with chronic pain in a random-effects model risk ratio (RR 0.80; 95% confidence interval (CI) 0.61 to 1.04; p = 0.09). There was also no significant effect on number of patients with recurrences in a random-effects model (RR 1.41; 95% CI 0.72 to 2.78; p = 0.32) and the TEP technique may or may not be associated with less severe adverse events (random-effects model RR 0.91; 95% CI 0.73 to 1.12; p = 0.37). TSA showed that the required information size was far from being reached for patient important outcomes. Conclusions/Significance TEP versus Lichtenstein for inguinal hernia repair has been evaluated by 13 trials with high risk of bias. The review with meta-analyses, TSA and error matrix approach shows no conclusive evidence of a difference between TEP and Lichtenstein on the primary outcomes chronic pain, recurrences, and severe adverse events.

Abstract
In this educational article, we aim to provide a literature review on laparoscopic anatomy of the inguinal region. We share the lessons learnt from the 1,194 laparoscopic hernia operations we have performed in 16 years of experience, trying to provide an anatomical and physiological basis for surgeons. The current study reports a personal experience with a transabdominal preperitoneal (TAPP) hernioplasty procedure. A literature review using the keywords "hernia," "laparoscopic approach," and "hernia repair" was performed using the electronic biomedical database PubMed, Medline Extra, Embase, Biosis, Science Citation Index, Ovid and text books. Between January 1994 and December 2010, a total of 1,194 patients, males and females (average age, 56.7 years), underwent laparoscopic TAPP inguinal hernia repair. Following reduction of the hernia sac and creation of the preperitoneal flap, a polypropylene mesh (10 × 16) and four spiral tacks were placed. TAPP is easy to learn and perform. Through this approach, a much better view from the inguinal anatomy is achieved, and the procedure also offers a brief learning curve. Our patients reported minimal postoperative pain and returned to work after 5-10 days, which is in accordance with the general anesthesia series. During the follow-up period, 10% of seromas, 3% of scrotal hematomas, 1% of hemorrhages, and 3% of recurrent hernias were observed. It should be emphasized that we have not observed abscess formation or acute infection related to the presence of mesh.

Abstract
INTRODUCTION Laparoscopic inguinal hernia repair can be performed totally extraperitoneal or transabdominal preperitoneal (TAPP). Both repairs are associated with mesh-related complications. This is the first report of a mesh-strangulated appendix, with subsequent necrosis and perforation, after TAPP inguinal hernia repair. CASE A 48-year-old male, 10-years status post-bilateral TAPP inguinal hernia repair presented with acute right groin bulge, pain, nausea, emesis, and fever. He was found to have a large, tender, nonreducible right groin mass. He was taken to the operating room for right groin exploration and found to have gross purulent material but no evidence of a recurrent hernia. A laparoscope was inserted into the abdomen where the appendix was found strangulated between the mesh and the transversalis fascia. CONCLUSIONS Mesh-related complications after TAPP inguinal hernia repair are rare. This is the first report of a strangulated appendix secondary to mesh entrapment after TAPP repair.

Abstract
In most countries, inguinal hernia repair is the most frequent procedure performed in a surgical practice. Different approaches have been developed during the last decades, with a strong tendency towards tension-free techniques. The laparoscopic approach offers advantages in terms of less postoperative pain and faster recovery with a low incidence in recurrence. In the last few years, single-incision laparoscopic surgery (SILS) has been introduced to further improve surgical outcome and cosmetic results. For SILS inguinal hernia repair, there is little data available so far, but both totally extraperitoneal hernia repair and transabdominal preperitoneal hernia repair have been succesfully performed without complications in a limited number of patients. In our experience, totally extraperitoneal hernia repair seems to be an ideal indication for the application of SILS.

Abstract
The safest and most effective inguinal hernia repair (laparoscopic versus open mesh) is being debated. As the authors point out, the former accounts for the minority of hernia repairs performed in the United States and around the world. The reasons for this are a demonstration in the literature of increased operative times, increased costs, and a longer learning curve. But the laparoscopic approach has clear advantages, including less acute and chronic postoperative pain, shorter convalescence, and earlier return to work. This article describes the transabdominal preperitoneal and totally extraperitoneal techniques, provides indications and contraindications for laparoscopic repair, discusses the advantages and disadvantages of each technique, and provides an overview of the literature comparing tension-free open and laparoscopic inguinal hernia repair.

Abstract
UNLABELLED In September 2004 the NICE institute revised its guidelines on the management of primary inguinal hernias to include laparoscopic repair of unilateral hernias. While published trials have confirmed the equal efficacy of the two approaches, it is not clear what impact a switch to laparoscopic repairs would have on resources and patient throughput in a Day Surgery Unit. METHOD All elective hernia repairs performed in a one-year period were considered. Data were obtained from operation notes, discharge summaries and out-patient records. Operating times are routinely documented in theatre. RESULTS Of the 351 operations studied, 150 were performed laparoscopically predominantly by an extraperitoneal (TEP)approach. Six required conversion to an open procedure. There was no significant difference in operating times, total theatre time or recovery room times between the two groups (51 min, 75 min and 34 min for the laparoscopic group and 53 min, 74 min and 31 min for the open repair group). Among the laparoscopic repair group there were 48 bilateral hernias and 20 recurrent hernias while 190 of the 201 open repairs were for primary unilateral hernias. Rates of overnight stay and immediate complications were similar between the groups though haematoma was more common following open repair (7 vs 2). CONCLUSIONS There is no difference in theatre times, immediate complication rates or rates of overnight stay between open and laparoscopic repair of inguinal hernia. Routine laparoscopic repair of primary unilateral inguinal hernia is a viable alternative within the Day Surgery Unit.

Abstract
BACKGROUND The laparoscopic repair of groin hernia is increasingly being used. However, the relative merits and demerits of laparoscopic repair are debatable. The present study was undertaken to evaluate the total extra-peritoneal (TEP) repair of groin hernia. METHODS This prospective study was undertaken at a single surgical unit between January 2004 and June 2006. Consecutive patients with elective groin hernias were offered laparoscopic TEP repair. Indigenous balloon or telescopic dissection was used to create extra-peritoneal space. Polypropylene mesh was used in all of the patients and mesh fixation was performed with tackers. RESULTS A total of 185 patients with age range 18-92 years were included; 180 were males. TEP repair was attempted in 298 groin hernias in 185 patients with a success rate of 89.5%. Indigenous balloon or telescopic dissection was used to create extra-peritoneal space. Thirty-one (31, 10.5%) TEP repairs were converted to transabdominal pre-peritoneal or open repair. Two patients developed recurrence during follow-up. CONCLUSION TEP is an excellent technique for laparoscopic groin hernia repair, with acceptable rates of complication.

Abstract
BACKGROUND Although a large number of surgeons currently perform endoscopic hernia surgery using a total extraperitoneal (TEP) approach, reviews published to date are based mainly on trials that compare laparoscopic transabdominal preperitoneal (TAPP) repair with various types of open inguinal hernia repair. METHODS A qualitative analysis of randomized trials comparing TEP with open mesh or sutured repair. RESULTS In this review, 4,231 patients were included in 23 trials. In 10 of 15 trials, TEP repair was associated with longer surgery time than open repair. A shorter postoperative hospital stay after TEP repair than after open repair was reported in 6 of 11 trials. In 8 of 9 trials, the time until return to work was significantly shorter after TEP repair. Hospital costs were significantly higher for TEP than for open repair in all four trials that included an economic evaluation. Most trials (n = 14) reported no differences in subsequent recurrence rates between TEP and open repair. CONCLUSIONS The findings showed that endoscopic TEP repair is associated with longer surgery time, shorter postoperative hospital stay, earlier return to work, and recurrence rates similar to those for open inguinal hernia repair. The procedure involves greater expenses for hospitals, but appears to be cost effective from a societal perspective. The TEP technique is a serious option for mesh repair of primary hernias.

Abstract
Traditionally, the operation of hernia is considered as a clean operation due to expected, low incidence of infection, on the spot of surgical work (SSI). The incidence of SSI in hernia surgery is more frequent then it is assumed. The important risk factors for SSI are the following: type of hernia (inguinal, incisional), operative approach (open - laparoscopic), usage of the prosthetic material and drainage. Comparing to inguinal hernia repair, incisional hernia repair, is more frequently followed by the infection. The laparoscopic operations are followed with the lower incidence of SSI then in the case of open operation. The usage of the mesh does not increase the incidence of SSI, although the consequences of the mesh infection may be severe. A type I of the prosthesis is more resistant to the infection then prosthesis II and III. The mesh infection (type I) never involves its body but it is present around sutures and bended edges. The mesh infection Type II involves entire prosthesis while in the case of Type III it is present in its peripheral part. In the case of SSI, a prosthesis Type I is possible to be saved, while prosthesis Type II must be removed completely; and the same is for the Type III (the partial removal is rarely suggested). The defect that remained after excision of non-resorptive prosthesis is a long-term and very complicated surgical problem. In regard to the position of the mesh, SSI is more common if the mesh is placed subcutaneously then in the case of sub-aponeurotic peri-muscular, pre-aponeurotic retromuscular or pre-peritoneal mesh placemen. If the infection is present the non-tension techniques using non-resorptive prosthetic implants are not recommended. the presence of drainage and its duration increases the incidence of SSI. It is more common for incisional hernioplasty then for inguinal hernia repair. If there is an indication for drainage it should be as short as possible. The cause of SSI for elective operations are bacteria?s that arrives from the skin, while in the case of opening of various organs dominant bacteria?s originate from them. The superficial infection does not lead to the recurrence, while it is very possible in the case for deep infection. There are no prospective studies that justify the usage of antibiotic prophylaxes in hernia surgery. The antibiotic prophylaxis in hernia surgery. The antibiotic prophylaxis is indicated for the clean operations when placing the implants and when severe complication is expected. The appearance of SSI increases the price of treatment and may lead to the recurrence.

Abstract
We compared a new fascia transversalis based hernioplasty with mesh repair techniques which leave the fascia transversalis intact. We prospectively randomized 180 consecutive patients with inguinal hernia to undergo one of the three hernia repair techniques. Hernias were repaired either by using the new fascia transversalis repair-Coskun's hernia repair (FTR), based on the plication of fascia using continuous sutures and followed by a second layer of interrupted or continuous sutures between inguinal ligament and conjoint tendon to distribute the tension, or one of the two mesh repair techniques: anterior (Lichtenstein) or posterior (preperitoneal) repair. Parameters such as age, sex, hernia cause, operation time, type of anesthesia, surgeon's seniority, complications, hospital stay and follow-up were evaluated. Recurrence rates were determined through clinical examination. Effect of prostatism, co-morbid disease, operation time, complications and Nyhus type of hernia on recurrences were also analysed. Most patients in each group were operated on under general anesthesia (78% vs. 80% vs. 85% for FTR, Lichtenstein, and preperitoneal repair, respectively) and by surgeons in training (average 78%). Patients were followed up for a median of 36 months. FTR had less complications and an acceptable time for operation whereas preperitoneal repairs needed more seniority, longer operation time, and caused more complications. There were only 3 (1.6%) recurrences, none in the FTR group and two the in Lichtenstein group during first postoperative year. There was no recurrence in preperitoneal repair group. All patients with recurrences had an operation time longer than 60 min and were operated on by surgeons in training. Two patients with recurrences had prostatism symptoms and chronic cough. We conclude that the new FTR is as effective as mesh repair (either anterior or posterior) with an acceptable rate of recurrences, fewer complications, and that it can be performed by the surgeons in training.

Abstract
BACKGROUND For the scientific evaluation of the endoscopic and open mesh techniques for the repair of inguinal hernia, meta-analyses of randomized controlled trials (RCT) are necessary. The Lichtenstein repair is one of the most common open mesh techniques and therefore of special interest. METHODS After an extensive search of the literature and a quality assessment, a total of 34 RCT comparing endoscopic procedures both transabdominal preperitoneal (TAPP) and total extraperitoneal (TEP)--with various open mesh repairs were deemed to be suitable for a formal meta-analysis of the relevant parameters. These studies included data for 7,223 patients. Trials that used the Lichtenstein repair for the control group (23 of 34 trials) were analyzed-separately. RESULTS Significant advantages for the endoscopic procedures compared with the Lichtenstein repair include a lower incidence of wound infection (Peto odds ratio, 0.39; 95% confidence interval, 0.26, 0.61), a reduction in hematoma formation (0.69 [0.54, 0.90]) and nerve injury (0.46 [0.35, 0.61]), an earlier return to normal activities or work (-1.35[-1.72, -0.97]), and fewer incidences of chronic pain syndrome (0.56[0.44, 0.70]). No difference was found in total morbidity or in the incidence of intestinal lesions, urinary bladder lesions, major vascular lesions, urinary retention and testicular problems. Significant advantages for the Lichtenstein repair include in a shorter operating time (5.45[1.18, 9.73]), a lower incidence of seroma formation (1.42[1.13, 1.79]), and fewer hernia recurrences (2.00[1.46, 2.74]). Similar results are seen when endoscopic procedures are compared with other open mesh repairs. However, in this comparison, total morbidity was lower with the endoscopic operations (0.73[0.61, 0.89]). The incidence of seroma formation, chronic pain syndromes, and hernia recurrence was not significantly different. CONCLUSION Endoscopic repairs do have advantages interms of local complications and pain-associated parameters. For more detailed evaluation further well-structured trials with improved standardization of hernia type, operative technique, and surgeons' experience are necessary.

Abstract
INTRODUCTION Chronic pain after hernia repair is common, and it is unclear to what extent the different operation techniques influence its incidence. The aim of the present study was to compare the three major standardized techniques of hernia repair with regard to postoperative pain. PATIENTS AND METHODS Two hundred and eighty male patients with primary hernias were prospectively, randomly selected to undergo Shouldice, tension-free Lichtenstein or laparoscopic transabdominal pre-peritoneal (TAPP) hernioplasty repairs. Patients were examined after 52 months with emphasis on chronic pain and its limitations to their quality of life. RESULTS Chronic pain was present in 36% of patients after Shouldice repair, in 31% after Lichtenstein repair and in 15% after TAPP repair. Pain correlated with physical strain in 25% of patients after Shouldice, in 20% after Lichtenstein and in 11% after TAPP repair. Limitations to daily life, leisure activities and sports occurred in 14% of patients after Shouldice, 13% after Lichtenstein and 2.4% after TAPP repair. CONCLUSION Chronic pain after hernia surgery is significantly more common with the open approach to the groin by Shouldice and Lichtenstein methods. The presence of the prosthetic mesh was not associated with significant postoperative complaints. The TAPP repair represents the most effective approach of the three techniques in the hands of an experienced surgeon.

Abstract
Endoscopic techniques are commonly used for many different types of surgery. It is claimed that videoendoscopic procedures have the advantage of being less traumatic and of offering higher postoperative patient comfort than conventional open techniques. The extent of tissue trauma can be evaluated on the basis of the inflammatory response observed in the wake of surgery. Available studies that have compared endoscopic and conventional techniques suggest that endoscopic cholecystectomy, laparoscopic colorectal resection, and thoracoscopic pulmonary resection have immunologic advantages over conventional approaches. The objective of this prospective study was to determine whether endoscopic hernia repair techniques are also preferable to conventional procedures and to what extent the anesthetic technique (local or general anesthesia) influences the postoperative inflammatory response. For this purpose, biochemical monitoring of cytokine activity [C-reactive protein (CRP), prostaglandin F1alpha (PGF1alpha), neopterin, interleukin-6 (IL-6)] was done prospectively in 101 patients [totally extraperitoneal approach (TEP) n=32, unilateral n=12, bilateral n=20; Shouldice n=69, local anesthesia (LA) n=23, general anesthesia (GA) n=46] before and until 3 days after surgery. The parameters IL-6 and PGF1alpha suggested that the immune trauma immediately after surgery was significantly higher in the group of patients with endoscopic hernia repair than in the group of patients who received a Shouldice repair. No significant differences were observed after the first postoperative day. A comparison between the TEP group and the patients who received conventional surgery under local anesthesia showed that the TEP approach was also associated with a higher postoperative neopterin level. Within the first 3 days after surgical intervention, bilateral endoscopic hernia repair induced no significantly higher inflammatory response than the surgical treatment of unilateral conditions. The anesthetic procedure that was used in the Shouldice operation had no significant effect on inflammatory response. Unlike other types of endoscopic surgery, the repair of groin hernias using an endoscopic technique cannot be regarded as a minimally invasive procedure that is less traumatic than conventional approaches. Instead, the conventional Shouldice procedure appears to cause the lowest inflammatory response and to be the least traumatic approach to hernia repair, especially when it is performed under local anesthesia.

[PMID: 14625733 DOI: 10.1007/s00464-003-8934-y] [Citation(s) in RCA: 58] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2003] [Accepted: 06/19/2003] [Indexed: 10/26/2022]
Abstract
BACKGROUND Although the laparoscopic totally extraperitoneal (TEP) approach to hernia repair has been associated with less pain and a faster postoperative recovery than traditional open repair, many practicing surgeons have been reluctant to adopt this technique because of the lengthy operative times and the learning curve for this procedure. METHODS Data from all patients undergoing TEP repair since 1997 and open mesh repair (OPEN) since 1999 were collected prospectively. Selection of surgical approach was based on local hernia factors, anesthetic risk, previous abdominal surgery, and patient preference. Statistical analyses were performed using unpaired t-tests and chi-squared tests. Data are mean +/- SD. RESULTS TEP repairs were performed in 147 patients and open repairs in 198 patients. Patients in the OPEN group were significantly older (59 +/- 19 years OPEN vs 51 +/- 13 years TEP) and had a higher ASA (1.9 +/- 0.7 OPEN vs 1.5 +/- 0.6 TEP; p < 0.01). TEP repairs were more likely to be carried out for bilateral (33% TEP, 5% OPEN) or recurrent hernias (31% TEP, 11% OPEN) than were open repairs ( p < 0.01). Concurrent procedures accompanied 31% of TEP and 12% of OPEN repairs ( p < 0.01). Operative times (min) were significantly shorter in the TEP group for both unilateral (63 +/- 22 TEP, 70 +/- 20 OPEN; p = 0.02) and bilateral (78 +/- 27 TEP, 102 +/- 27 OPEN; p = 0.01) repairs. Mean operative times decreased over time in the TEP group for both unilateral and bilateral repairs ( p < 0.01). Patients undergoing TEP were more likely ( p < 0.01) to develop urinary retention (7.9% TEP, 1.1% OPEN), but were less likely ( p < 0.01) to have skin numbness (2.8% TEP, 35.8% OPEN) or prolonged groin discomfort (1.4% TEP, 5.3% OPEN). CONCLUSIONS Despite a higher proportion of patients undergoing bilateral repairs, recurrent hernia repair, and concurrent procedures, operative times are shorter for laparoscopic TEP repair than for open mesh repair. TEP repairs can be performed efficiently and without major complications, even when the learning curve is included.

Abstract
BACKGROUND The aim was to conduct a meta-analysis of the randomized evidence to determine the relative merits of laparoscopic (LIHR) and open (OIHR) inguinal hernia repair. METHODS A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified all randomized clinical trials that compared OIHR and LIHR and were published in the English language between January 1990 and the end of October 2000. The meta-analysis was prepared in accordance with the Quality of Reporting of Meta-analyses (QUOROM) statement. The six outcome variables analysed were operating time, time to discharge from hospital, return to normal activity and return to work, postoperative complications and recurrence rate. Random effects meta-analyses were performed using odds ratios and weighted mean differences. RESULTS Twenty-nine trials were considered suitable for meta-analysis. Some 3017 hernias were repaired laparoscopically and 2972 hernias were repaired using an open method in 5588 patients. For four of the six outcomes the summary point estimates favoured LIHR over OIHR; there was a significant reduction of 38 per cent in the relative odds of postoperative complications (odds ratio 0.62 (95 per cent confidence interval (c.i.) 0.46 to 0.84); P = 0.002), 4.73 (95 per cent c.i. 3.51 to 5.96) days in time to return to normal activity (P < 0.001), 6.96 (95 per cent c.i. 5.34 to 8.58) days in time to return to work (P < 0.001) and 3.43 (95 per cent c.i. 0.35 to 6.50) h in time to discharge from hospital (P = 0.029). There was a significant increase of 15.20 (95 per cent c.i. 7.78 to 22.63) min in the mean operating time for LIHR (P < 0.001). The relative odds of short-term recurrence were increased by 50 per cent for LIHR compared with OIHR, although this result was not statistically significant (odds ratio 1.51 (95 per cent c.i. 0.81 to 2.79); P = 0.194). CONCLUSION LIHR was associated with earlier discharge from hospital, quicker return to normal activity and work, and significantly fewer postoperative complications than OIHR. However, the operating time was significantly longer and there was a trend towards an increase in the relative odds of recurrence after laparoscopic repair.

Abstract
BACKGROUND Laparoscopic treatment of acutely incarcerated inguinal hernia is uncommon and still controversial. Those being performed almost all use the transabdominal (TAPP) approach. The authors here present their experience with totally extraperitoneal (TEP) repair of acutely incarcerated hernia. METHODS A retrospective review was undertaken to evaluate the authors' experience with this procedure over a 4-year period. There were 16 cases, 5 of which were performed using a conventional anterior repair. These 5 cases were excluded from the review. The surgery for all of the remaining 11 acutely incarcerated hernias was started laparoscopically using the TEP approach. Eight of the cases were completed this way, whereas three were converted to the open procedure. In addition to standard TEP repair techniques, a releasing incision is required for acutely incarcerated direct, indirect, or femoral hernias. With a direct hernia, the opening of the defect is enlarged to allow safe dissection of its contents. A releasing incision is made at the anteromedial aspect of the defect to avoid injury to the epigastric or iliac vessels. With an indirect hernia, several additional steps are required. The epigastric vessels may be divided; an additional trocar may be placed laterally below the linea semicircularis to facilitate dissection of the sac and to assist with suturing of the divided sac; and the deep internal ring is divided anteriorly at the 12 o'clock position toward the external ring, facilitating dissection of the indirect sac. With a femoral hernia, a releasing incision is made by carefully incising the insertion of the iliopubic tract into Cooper's ligament at the medial portion of the femoral ring. RESULTS The mean operative time was 50 min (range, 20-120 min), and the length of hospital stay was 5.4 days (range, 1-29 days). During a follow-up period of 9 to 69 months, there was no recurrence, and only two complications. One of these complications was an infected mesh that occurred in a case involving cecal injury. It was treated with continuous irrigation and salvaged. The other complication was a midline wound infection after a small bowel resection for a strangulated obturator hernia. CONCLUSIONS Familiarity with the anatomy involved leads to the conclusion that the laparoscopic approach, specifically the TEP procedure, can be used without hesitation even in cases of acutely incarcerated hernia.

Abstract
Outcomes studies after inguinal hernia operations show a pattern of continued improvement throughout the last decade. OHRs are intrinsically less costly and less complicated to perform than LHR. The most recent modification in OHR has been the improvement of the mesh prostheses for insertion into the preperitoneal space. The earlier return to work seen in the early 1990s with LHR has been offset by comparable recuperation in the late 1990s associated with improvements in prosthetic repair in OHR. Both behavioral and technical factors must be evaluated to improve outcomes with hernia surgery.

Abstract
Laparoscopic hernia repair is safe and effective and may result in less postoperative pain and faster recuperation compared with traditional open hernia repairs. Controversy exists as to the increased cost associated with laparoscopic repairs. The purpose of this study was to quantify and compare the cost of the totally extraperitoneal (TEP) laparoscopic repair and the tension-free Lichtenstein repair at teaching hospitals. The records of consecutive TEP (n = 28) and Lichtenstein (n = 28) repairs performed at Parkland Memorial Hospital and Zale-Lipshy University Hospital were reviewed. A detailed cost analysis was performed. Total patient charge (5,509 US dollars vs. 3,999 US dollars) and total cost (2,861 US dollars vs. 2,009 US dollars) were higher for TEP versus Lichtenstein repairs, respectively (P < 0.05). Operative time and complications were similar for both groups. Return to full activity (15 vs. 34 days) was faster for TEP versus Lichtenstein repairs, respectively (P < 0.05). Of 9 patients in the TEP group who had previously undergone an open hernia repair, 8 (89%) preferred the laparoscopic approach. The laparoscopic TEP repair costs 852 US dollars more than the Lichtenstein repair. The TEP repair results in faster recuperation. Patient preference and faster recuperation may offset the increased cost associated with laparoscopic hernia repair.

Abstract
BACKGROUND This study was designed to compare an open tension-free technique (Lichtenstein repair) with a laparoscopic totally extraperitoneal hernia repair (TEP). METHODS One hundred sixty-eight men aged 30 to 65 years with primary or recurrent inguinal hernia were randomized to TEP or open mesh technique in the manner of Lichtenstein. Follow-up was after 1 and 6 weeks, and 1 year. RESULTS Eighty-one patients were randomized to TEP, and 87 to open repair. For 1 patient in each group, the operation was converted to a different type of repair. No difference was seen in overall complications between the 2 groups. However, 1 patient in the TEP group underwent operation for small bowel obstruction after surgery. A higher frequency of postoperative hematomas was seen in the open group (P <.05). Patients in the TEP group consumed less analgesic after surgery (P <.001), returned to work earlier (P <.01), and had a shorter time to full recovery (P <.01). Two recurrences occurred in the TEP group 1 year after surgery. CONCLUSION The TEP technique was associated with less postoperative pain, a shorter time to full recovery, and an earlier return to work compared with the open tension-free repair. No difference was seen in overall complications. However, 2 recurrences did occur after 1 year in the TEP group.

Abstract
BACKGROUND Inguinal hernia repair is the most frequently performed operation in general surgery. The standard method for inguinal hernia repair had changed little over a hundred years until the introduction of synthetic mesh. This mesh can be placed by either using an open approach or by using a minimal access laparoscopic technique. Although many studies have explored the relative merits and potential risks of laparoscopic surgery for the repair of inguinal hernia, most individual trials have been too small to show clear benefits of one type of surgical repair over another. OBJECTIVES The objective of this review was to compare minimal access laparoscopic mesh techniques with open techniques. Comparisons of open mesh techniques versus open non-mesh techniques have been considered in a separate Cochrane review. SEARCH STRATEGY We searched MEDLINE, EMBASE, and The Cochrane Central Controlled Trials Registry for relevant randomised controlled trials. The reference list of identified trials, journal supplements, relevant book chapters and conference proceedings were searched for further relevant trials. Through the EU Hernia Trialists Collaboration (EUHTC) communication took place with authors of identified randomised controlled trials to ask for information on any other recent and ongoing trials known to them. Specialists involved in research on the repair of inguinal hernia were contacted to ask for information about any further completed and ongoing trials. The world wide web was also searched. SELECTION CRITERIA All published and unpublished randomised controlled trials and quasi-randomised controlled trials comparing laparoscopic groin hernia repair with open groin hernia repair were eligible for inclusion. Trials were included irrespective of the language in which they were reported. DATA COLLECTION AND ANALYSIS Individual patient data were obtained, where possible, from the responsible trialist for all eligible studies. All reanalyses were cross-checked by the reviewers and verified by the trialists before inclusion. Where IPD were unavailable additional aggregate data were sought from trialists and published aggregate data checked and verified by the trialists. IPD were available for 25 trials, additional aggregated data for seven and published data only for nine. Where possible, time to event analysis for hernia recurrence and return to usual activities were performed on an intention to treat principle. The main analyses were based on all trials. Sensitivity analyses based on the data source and trial quality were also performed. Pre-defined subgroup analyses based on recurrent hernias, bilateral hernias and femoral hernias were also carried out. MAIN RESULTS 41 published reports of eligible trials were included involving 7161 participants. Sample sizes ranged from 38 to 994, with follow-up from 6 weeks to 36 months. Duration of operation was longer in the laparoscopic groups (WMD 14.81 minutes, 95% CI 13.98 to 15.64; p<0001). Operative complications were uncommon for both methods but more frequent in the laparoscopic group for visceral (Overall 8/2315 versus 1/2599) and vascular (Overall 7/2498 versus 5/2758) injuries. Length of hospital stay did not differ between groups (WMD -0.04 days, 95% CI -0.08 to 0.00; p=0.05, but return to usual activity was earlier for laparoscopic groups (HR 0.56, 95%CI 0.51 to 0.61; p<0.0001 - equivalent to 7 days). The data available showed less persisting pain (Overall 290/2101 versus 459/2399; Peto OR 0.54, 95% CI 0.46 to 0.64; p<0.0001), and less persisting numbness (Overall 102/1419 versus 217/1624; Peto OR 0.38, 95% CI 0.4286 to 0.49; p<0.0001) in the laparoscopic groups. In total, 86 recurrences were reported amongst 3138 allocated laparoscopic repair and 109 amongst 3504 allocated to open repair (Peto OR 0.81, 95% CI 0.61 to 1.08; p = 0.16). The use of mesh during laparoscopic hernia repair is associated with a reduction in the risk of hernia recurrence, significantly so for the transabdominal preperitoneal repair (TAPP) versus open non-mesh repair (overall 26/1440 versus preperitoneal repair (TAPP) versus open non-mesh repair (overall 26/1440 versus 47/1119; Peto OR 0.45, 95% CI 0.28 to 0.72; p=0.0009). However, no difference was detected when comparing laparoscopic methods with open mesh methods of hernia repair. REVIEWER'S CONCLUSIONS The use of mesh during laparoscopic hernia repair is associated with a relative reduction in the risk of hernia recurrence of around 30-50%. However, there is no apparent difference in recurrence between laparoscopic and open mesh methods of hernia repair. The data suggests less persisting pain and numbness following laparoscopic repair. Return to usual activities is faster. However, operation times are longer and there appears to be a higher risk of serious complication rate in respect of visceral (especially bladder) and vascular injuries.

Abstract
BACKGROUND The aim of this study was to compare the incidence of chronic pain or discomfort after laparoscopic totally extraperitoneal (TEP) repair and open mesh repair of groin hernia, and to assess the impact of such pain on patients' physical activity. METHODS A postal questionnaire was sent to patients who had TEP or open mesh repair of groin hernia between January 1998 and December 1999. The patients were asked about any persistent pain or discomfort in relation to the groin hernia repair and whether this pain or discomfort restricted their ability to undertake physical or sporting activity. RESULTS Of the 560 available patients 454 (81.1 per cent) replied. Laparoscopic TEP repair was performed in 240 patients (52.9 per cent) and open mesh repair in 214 (47.1 per cent). Of the 454 patients, 136 (30.0 per cent) reported chronic groin pain or discomfort, which was significantly more common after open repair than after laparoscopic repair (38.3 versus 22.5 per cent; P < 0.01). Chronic groin pain or discomfort restricted daily physical or sporting activity in 18.1 per cent of the patients. The patients who had open repair complained of significantly more restriction of daily physical activity than patients who underwent laparoscopic repair (walking, P < 0.05; lifting a bag of groceries, P < 0.01). CONCLUSION Chronic pain or discomfort was reported by 30.0 per cent of patients after groin hernia repair and was significantly more common after open mesh repair than after laparoscopic TEP repair. It restricted physical or sporting activities in 18.1 per cent of the patients and significantly more so after open mesh repair.

Abstract
BACKGROUND This meta-analysis was performed to determine the degree to which improvements in open hernia repair (OHR) in the last decade have altered the relative benefit of laparoscopic hernia repair (LHR). METHODS Twenty-seven comparative trials including 4,688 randomized patients were evaluated. RESULTS Within the control OHR, patients with routine mesh repair returned to work earlier than a sutured repair (16.4 versus 27.3 days, P = 0.010). During the study period, the increased use of mesh in OHR (3 of 12 initially versus 9 of 15 subsequent studies) was associated with an earlier return to work (25.9 to 16.8 days, P = 0.017); there was no significant improvement with corresponding LHR. CONCLUSIONS Although LHR was associated with an earlier return to work compared with conventional sutured OHR, more recent mesh OHRs provide equivalent outcomes but at lower costs and potentially less severe complications, supporting an open technique using preperitoneal mesh prostheses as the optimal hernia repair.

Abstract
BACKGROUND Laparoscopic surgery is believed to produce an attenuated metabolic stress response and to have a less dampening effect on the immune response than open surgery. To date, the effect has not been studied in a randomized clinical trial of colorectal cancer. METHODS The study was a two-armed randomized prospective trial conducted in parallel with the UK Medical Research Council's Conventional versus Laparoscopic-Assisted Surgery in Colorectal Cancer (CLASICC) trial comparing laparoscopically assisted colorectal surgery for left-sided tumours with conventional open surgery. Systemic immunity was assessed by determining the T- and B-cell counts, the CD4 : CD8 ratio, the natural killer cell counts, the immunoglobulin (Ig) G, IgM and IgA levels, and C3 and C4 levels. The white cell phagocytic activity (nitroblue tetrazolium test) was studied before operation and on the third postoperative day. RESULTS A total of 236 patients were randomized in the immune study between 11 March 1997 and 14 August 1999; 161 had complete preoperative and postoperative assays for the analysis of results. There was no difference in mean response between the two surgical groups for each of the immune parameters studied. The unadjusted difference for the primary endpoint, T-cell count, 3 days after operation was - 1.6 per cent (95 per cent confidence interval - 5.0 to 1.8 per cent). CONCLUSION There is no difference in the systemic immune response in patients having laparoscopically assisted colectomy compared with those undergoing conventional open surgery for colorectal cancer.

Abstract
Laparoscopic inguinal herniorrhaphy (LIHR) was introduced with the following potential advantages: less postoperative discomfort and pain, reduced recovery time that allows earlier return to full activity, easier repair of a recurrent hernia, the ability to treat bilateral hernias concurrently, the performance of a simultaneous diagnostic laparoscopy, ligation of the hernia sac at the highest possible site, improved cosmesis, and decreased incidence of recurrence. Potential disadvantages include complications, such as bowel, bladder, and vascular injuries; potential adhesive complications at sites where the peritoneum has been breached or prosthetic material has been placed; the apparent need, at least at the present, for a general anesthetic; and the increased cost because of expensive equipment needs. Most surgeons agree that LIHR has a role in the management of patients with a recurrent hernia after a conventional inguinal herniorrhaphy (CIHR), bilateral inguinal hernia, or a need for laparoscopy for another procedure, such as laparoscopic cholecystectomy. The routine use of LIHR for the unilateral, uncomplicated hernia is a more contentious issue.

Abstract
Prosthetic mesh can contract by 20-75% of its original size within ten months after implantation. We set out to determine whether this contraction has any effect on testicular or femoral vessel blood flow following open or laparoscopic hernia repair. Twenty patients who underwent mesh repair of a primary unilateral inguinal hernia repair by Open (10) or Laparoscopic (10) methods a median of 3 years previously were investigated by ultrasound to determine the haemodynamic characteristics of the testis and femoral vessels. There was no significant difference in testicular blood flow, volume or echogenicity between the different types of repair or the contralateral side. The vertical and transverse dimensions of the femoral artery and vein were similar in all groups as was blood flow. Mesh contraction following inguinal hernioplasty does not adversely affect the testis or femoral vessels and can be used safely for both anterior and preperitoneal approaches.

Abstract
BACKGROUND One year after publication of a Dutch prospective trial randomizing patients with inguinal hernias to either endoscopic or open repair, a questionnaire was sent to all Dutch surgeons to evaluate the impact of this trial on the application of endoscopic inguinal hernia repair in the Netherlands. METHODS All 780 registered Dutch surgeons were surveyed. The performance of endoscopic inguinal hernia repair, the technique and the indications, the involvement of surgical residents, the motives for use of conventional techniques, and the type of open repair were documented. RESULTS The response rate was 100%. Endoscopic inguinal hernia repair was performed by 16% of Dutch surgeons. For 81% of the surgeons, the total extraperitoneal approach was the preferred endoscopic technique. Primary inguinal hernias were approached endoscopically by only 54% of these surgeons, and recurrent hernias by 92%. The technique of choice for open repair of primary hernias was the Shouldice repair. The predominant repair for recurrent inguinal hernias was the Lichtenstein technique. CONCLUSIONS Although randomized clinical trials have provided evidence that the endoscopic approach to inguinal hernias is preferable, only 1 of 6 Dutch surgeons has adopted endoscopic inguinal hernia repair. Improvement in training of both surgical residents and surgeons and increasing awareness among medical doctors and patients about the benefits of endoscopic inguinal hernia repair are necessary to enhance the acceptance of this valuable technique for inguinal hernia repair.

Abstract
BACKGROUND Despite numerous attempts to improve the techniques used for hernia repair, current published series show that recurrence rates are as high as 5-20%. The complexity of inguinal anatomy, combined with multiple potential areas of weakness, has contributed to the difficulty in preventing recurrences. However, the laparoscopic approach to inguinal herniorrhaphy has allowed clear visualization of all preperitoneal fascial planes and anatomic landmarks, as well as the hernia defect(s) and the peritoneal reflection. In the course of our performance of a series of 1,224 laparoscopic inguinal hernia repairs, we have developed a total extraperitoneal approach that yields excellent results with a low initial recurrence rate. Herein we describe our experience. METHODS After our initial 300 transabdominal preperitoneal (TAPP) hernia repairs, which resulted in six recurrences, two bowel injuries, one bladder injury, and six cutaneous nerve injuries, the total extraperitoneal approach (TEP) was adopted. RESULTS The first 300 TEP repairs resulted in one recurrence, two bowel injuries, one bladder injury, and two cutaneous nerve injuries. All major complications occurred in patients who had had previous lower abdominal surgery. In the last 624 TEP herniorrhaphies we implemented some modifications to the technique, especially for patients with previous lower abdominal surgery. In this group we recorded one bladder injury, no cutaneous nerve injuries, and one recurrence. CONCLUSIONS The total extraperitoneal approach for laparoscopic herniorrhaphy allows for a safe and effective repair with low rates of complication and recurrence. A thorough knowledge of the anatomy of the extraperitoneal space and especially the two- and three-dimensional inguinal anatomy of this space contributed greatly to the evolution of our technique.

Abstract
UNLABELLED Transabdominal preperitoneal (TAPP) or total extraperitoneal (TEP) hernioplasty are probably associated with differing degrees of CO(2) absorption which can influence anesthetic management and perioperative morbidity. We studied 20 patients with either TAPP or TEP for perioperative CO(2) absorption (calculated from CO(2) elimination and metabolic CO(2) production) and ventilatory changes required to maintain normocapnia (blood gas analyses). CO(2) absorption reached plateau values in the TAPP group, but increased over time in the TEP group. Median CO(2) absorption during insufflation was 61 mL/min (range 43-78) for TAPP and 114 mL/min (range 75-178) for TEP, with a maximum of 114 mL/min (range 75-178) for TAPP and 258 mL/min (range 112-585) for TEP. Median minute ventilation (V(E)) required for maintaining normocapnia was 9. 5 L/min (range 7.7-11.5) for TAPP and 12.9 L/min (range 9.0-22.6) for TEP (P: < 0.01). Seven patients in the TEP group required over 18 L/min V(E), although no patient in the TAPP group required more than 14 L/min V(E). All patients in the TEP group had significant subcutaneous emphysema resulting in one case of delayed tracheal extubation. We conclude that CO(2) absorption is consistently less with TAPP. IMPLICATIONS The greater magnitude of carbon dioxide absorption during total extraperitoneal hernioplasty puts an additional load on the lungs and could pose a risk for patients with chronic lung disease who might be unable to eliminate excess carbon dioxide.

Abstract
BACKGROUND At present only short-term follow-up data are available to compare endoscopic and conventional hernia surgery. This paper presents data from a randomized study 6 years after initial recruitment. METHODS In 1993 a randomized comparative study of transabdominal preperitoneal (TAPP) and Shouldice repair was commenced. Endpoints were rate of recurrence, late complications, complaints and patient satisfaction. RESULTS The rate of recurrence in the TAPP group was one (2 per cent) of 48 patients and in the Shouldice group two (5 per cent) of 43. Only five patients in the Shouldice and three in the TAPP group reported slight discomfort in the inguinal region at 6-year follow-up. In neither group was chronic pain syndrome observed. Altogether, 46 (96 per cent) of 48 patients in the TAPP group and 35 (81 per cent) of 43 of those having the Shouldice procedure stated complete satisfaction with the hernia repair. CONCLUSION Long-term evaluation demonstrated greater satisfaction with the result of the repair in the endoscopic group. The difference between the groups in the recurrence rate was not significant, because of the small numbers. The TAPP method appears to be an effective surgical alternative in patients with inguinal hernia.

Abstract
STUDY AIM The aim of this retrospective study was to report a series of laparoscopic hernioplasty performed in two surgical centers, and to evaluate the results with a mean follow-up of 31 months. PATIENTS AND METHODS From January 1992 to January 1997, 318 patients with 401 inguinal hernias were operated on through laparoscopy by six senior surgeons and six junior surgeons. There were 302 men and 16 women (mean age: 53 years). The operation was performed through an extra-peritoneal approach (TEP) in 298 hernias, a trans-abdomino-preperitoneal approach (TAPP) in 62 hernias, and an intra-abdominal approach (IPOM) in 41 hernias. RESULTS Conversion into open surgery was necessary in 7% of the patients. There was no postoperative death. The postoperative morbidity rate was 10%. The average hospital stay was three days. With a 1 to 5 year follow-up, 4% of the 94% of the patients who answered the questionnaire showed a recurrence (3% in the extra-peritoneal group; 4% in the trans abdomino-preperitoneal group; 10% in the intra-abdominal group). CONCLUSION Laparoscopic hernioplasty seems as efficient as traditional hernoplasty with the advantages of mini-invasive surgery. The extra-peritoneal approach was preferred and performed in most cases of this series. The intra-peritoneal approach was abandoned.
