2008, Hernia : the journal of hernias and abdominal wall surgery
A consecutive series of 255 women with primary groin hernias repaired electively over a five-year period, was reviewed. There were 271 hernias; the majority, 182 (67%) were indirect inguinal hernias, 35 (14%) were direct, and 54 (20%) were femoral. There were no major post-op complications and no recurrences. Most patients presented with a swelling but in 13 cases there was pre-operative discomfort only. Groin pain in women should arouse suspicion of an occult hernia. Lichtenstein repair for inguinal hernia is easier than in men, and as effective.
British Journal of Surgery, 2005
Background: Although 8 per cent of groin hernia repairs are performed in women, there is little published literature relating specifically to women. This study compared differences in outcome between women and men after groin hernia repair.

Introduction: Groin hernias are common problem worldwide with approximate incidence of 5%. Indirect inguinal hernia is the commonest hernia irrespective of gender. The prevalence as well as complication of inguinal hernia will increase with increasing age. Strangulation, the most common serious complication of inguinal hernia occurs in 1 to 3 % of the patients. Outcome of the treatment depends on the duration of presentation, co-morbidities and extent of the surgery.Objective: The objectives were to study the different clinical presentation, surgical options and outcome of complicated groin hernia in tertiary care centre.Methodology: This retrospective review of case sheet was conducted in the department of surgery. We reviewed the record file of complicated groin hernia patients, irrespective of age and gender from January 2008 to December 2016 (8 years). Ethical Clearance was obtained from institutional review committee. Statistical analysis was performed using SPSS for windows, v...

Background: Groin hernia is an uncommon surgical pathology in females. The efficacy of the endoscopic approach for the repair of female groin hernia has yet to be examined. The current study was undertaken to compare the clinical outcomes of female patients who underwent open and endoscopic totally extraperitoneal inguinal or femoral hernioplasty (TEP). Methods: From July 1998 to June 2004, 108 female patients who underwent elective repair of groin hernia were recruited. The patients were divided into TEP (n = 30) and open groups (n = 78) based on the type of operation. Clinical data and outcome parameters were compared between the two groups. Results: The mean ages and hernia types were comparable between the two groups. All TEPs were successfully performed. The mean operative times were 52 min for unilateral TEP and 51 min for open repair. The difference was not statistically significant. Comparisons of the length of hospital stay, postoperative morbidity, pain score, and time taken to resume normal activities showed no significant differences between the two groups. A single patient in the TEP group experienced recurrence of hernia. Conclusions: The findings show equivalent postoperative outcomes after TEP and open repair of groin hernia in female patients. Because the wound scar after open repair is well concealed beneath the pubic hair and no superior clinical benefits are observed after TEP, open repair appears to be the technique of choice for the management of primary groin hernia in females. The TEP approach should be reserved for female patients with recurrent or multiple groin hernia.

Purpose Hernia repairs are a common surgical procedure, and are associated with a significant cost. Despite the acceptance of the advantages of early elective hernia repairs, the incidence of emergency admissions with complicated presentations remains high, and the natural history of an untreated hernia is not obvious. This study aimed to define risk factors related with unfavorable outcomes in groin hernia repairs. Methods We analyzed the records of 685 elective or emergency repairs of groin hernias between December 2005 and June 2009. Patient age ranged from 17 to 85 years, with 240 (35%) of patients being older than 60 years of age. Indirect inguinal hernias were the most common hernia type in both sexes of patients. Coexisting cardiopulmonary problems were noted in 294 male and 33 female patients. American Society of Anaesthesiologists (ASA) grades 3 and 4 were encountered in 61 (9%) patients. Data were analyzed by chi-square test. Results Significantly high incarceration and strangulation rates were found in females and femoral hernia type. The overall morbidity rate was 7%, major complications 3%. No mortality was observed in the series and postoperative complications were significantly more common in patients with high ASA score and severe coexisting cardiopulmonary problems. Advanced age, delayed admission, femoral type hernia and female sex were also linked with unfavorable outcomes. Conclusions The risk of complicated presentation and unfavorable outcome in patients with groin hernia is significant in the presence of factors such as advanced age, femoral hernia, female sex, delayed admission, severe coexisting cardiopulmonary problems and high ASA score. Although it is difficult to estimate the natural history of untreated hernia, hernia repairs of patients with the above-mentioned risk factors should be timely and elective.
Hernia : the journal of hernias and abdominal wall surgery, 2011
Groin herniorrhaphy is the most common operation performed by general surgeons. Annually, more than 20 million groin hernias are repaired worldwide. The general approach towards groin hernias is surgical repair regardless of the presence of symptoms. The rationale to recommend surgery for asymptomatic groin hernias is prevention of visceral strangulation. The goal of this review is to evaluate the appropriateness of surgery in patients with asymptomatic groin hernias. The review was based on an extensive literature search of Pubmed, Medline and the Cochrane Library. The risk of incarceration is approximately 4 per 1,000 patients with a groin hernia per year. Risk factors for incarceration are age above 60 years, femoral hernia site and duration of signs less than 3 months. Morbidity and mortality rates of emergency groin hernia repair are higher in patients who are older than 49 years, have a delay between onset of symptoms and surgery of more than 12 h, have a femoral hernia, have ...
Current Surgery, 2005
Currently, operative repair of inguinal hernia is most often performed using one of the open mesh procedures or laparoscopic techniques. These newer approaches minimize anatomical dissection critical to the time-honored traditional hernia surgery described by Bassini, Halsted, McVay, Laroque, Shouldice, and other early pioneers. The familiarity with groin anatomy and the technical skill gained in performing these operations is currently missing from present-day surgical residency training. This article reviews 5 classic hernia operations described by the surgeons whose name they bear, with a view toward better understanding the authors' techniques and philosophies. Each of these operations, though considered by some as of historical interest only, offers today's surgeon reliable alternatives when the simple application of mesh by open or laparoscopic technique is inappropriate.

Background: Groin hernia is one of the most frequently encountered pathologies occurring in old age and it is often the cause of emergency procedures. In our study we evaluate the impact of emergency procedures in over 75 patients compared to younger patients. Methods: We conducted a retrospective study about patients who underwent emergency hernioplasty between September 2007 and January 2013. Bilateral hernias and recurrences were excluded. We divided patients into two groups by age (under and over 75 years old) and then analyzed the early postoperative surgical complications. Results: A total of 48 patients were enrolled, 18 were included in under 75 group and 30 in over 75. In the older group we found a higher rate of comorbidity and also a significant higher rate of postoperative complications. Two patients of over 75 group died. Conclusions: Our data suggests that a quick diagnosis and elective surgical procedures are desirable in order to avoid the complications that occur in emergency operations. Compagna et al.

Traditional methods of clinical research may not be adequate to improve the value of care for patients with complex medical problems such as chronic pain after inguinal hernia repair. This problem is very complex with many potential factors contributing to the development of this complication. We have implemented a clinical quality improvement (CQI) effort in an attempt to better measure and improve outcomes for patients suffering with chronic groin pain (inguinodynia) after inguinal hernia repair. Between April 2011 and June 2016, there were 93 patients who underwent 94 operations in an attempt to relieve pain (1 patient had two separate unilateral procedures). Patients who had prior laparoscopic inguinal hernia repair (26) had their procedure completed laparoscopically. Patients who had open inguinal hernia repair (68) had a combination of a laparoscopic and open procedure in an attempt to relieve pain. Initiatives to attempt to improve measurement and outcomes during this period ...

Inguinal herniorrhaphy is one of the most common operations in general surgery wards worldwide. Tension free techniques with mesh implantation (among Lichtenstein most common) reduced recurrence rate to less than 1%. Chronic pain comprising up to 40% of operated patients still remains a clinical problem. Laparoscopic (endoscopic) techniques avoid extensive preparation in the groin, what is more hernia mesh is placed in avascular space of Borgios which contribute to reduction in chronic pain level. Apart from mentioned advantages laparoscopy (endoscopy) have drawbacks as well, among which high cost and long learning curve has to be taken into account. Currently many authors are keen on preperitoneal non laparoscopic minimal incision hernioplasty which result in few recently published operation techniques. In the article we present new hernioplasty methods and discuss them.

Background Groin hernia management has a significant worldwide diversity with multiple surgical techniques and variable outcomes. The International guidelines for groin hernia management serve to help in groin hernia management, but the acceptance among general surgeons remains unknown. The aim of our study was to gauge the degree of agreement with the guidelines among health care professionals worldwide. Methods Forty-six key statements and recommendations of the International guidelines for groin hernia management were selected and presented at plenary consensus conferences at four international congresses in Europe, the America's and Asia. Participants could cast their votes through live voting. Additionally, a web survey was sent out to all society members allowing online voting after each congress. Consensus was defined as > 70% agreement among all participants. Results In total 822 surgeons cast their vote on the key statements and recommendations during the four plenary consensus meetings or via the web survey. Consensus was reached on 34 out of 39 (87%) recommendations, and on six out of seven (86%) statements. No consensus was reached on the use of light versus heavyweight meshes (69%), superior cost-effectiveness of day-case laparo-endoscopic repair (69%), omitting prophylactic antibiotics in hernia repair, general or local versus regional anesthesia in elderly patients (55%) and re-operation in case of immediate postoperative pain (59%). Conclusion Globally, there is 87% consensus regarding the diagnosis and management of groin hernias. This provides a solid basis for standardizing the care path of patients with groin hernias.

Background Transcatheter aortic valve implantation (TAVI) via total percutaneous transfemoral approach is an increasingly common technique for aortic stenosis treatment. It is primarily indicated in elderly with serious comorbidities. The epidemiology of these patients tends to overlap with the incidence of femoral hernia (FH). The appearance of hernia sac at the approach site and insufficient preoperational examination can lead to serious complications. We present the first-ever reported case of subsequent femoral hernia repair during transfemoral TAVI. Case presentation This report presents a case of FH/TAVI coincidence and literature review of its epidemiology. Literature review was performed to analyze similarities of femoral hernia and TAVI. The case describes an 84-year old female referred for elective TAVI. Intraoperation incarcerated femoral hernia was noticed and directly repaired. Further TAVI steps were performed on regular basis. A 2-year follow-up reported no local and ...

An indirect inguinal hernia containing an incarcerated fallopian tube and ovary is extremely rare in adult females. The current report describes a woman of reproductive years presenting with an irreducible indirect hernia which required the surgical intervention of a general surgeon as well as counseling regarding future fertility by a gynecologist. The diagnosis was made by physical and sonographic examination and was confirmed by CT scan and surgical intervention. We suggest a multimodel and multidisciplinary approach in order to safely and efficiently preserve ovarian and fertility function in young women who present with an inguinal hernia containing reproductive organs.

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. Results and summary 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 The guidelines have been endorsed by the following societies: European Hernia Society (EHS), Americas Hernia Society (AHS),

RESUMO As hérnias inguinais são um problema frequente e o seu reparo representa a cirurgia mais comumente realizada por cirurgiões gerais. Nos últimos anos, novos princípios, produtos e técnicas têm mudado a rotina dos cirurgiões que precisam reciclar conhecimentos e aperfeiçoar novas habilidades. Além disso, antigos conceitos sobre indicação cirúrgica e riscos de complicações vêm sendo reavaliados. Visando criar um guia de orientações sobre o manejo das hérnias inguinais em pacientes adultos, a Sociedade Brasileira de Hérnias reuniu um grupo de experts com objetivo de revisar diversos tópicos, como indicação cirúrgica, manejo perioperatório, técnicas cirúrgicas, complicações e orientações pós-operatórias.

Inguinal hernia is the most common hernia that affects the anterior abdominal wall. It is important to note that increased intra-abdominal pressure is a major risk factor of inguinal hernia formation. An indirect inguinal hernia in the right groin region causing small bowel obstruction is rare in elderly females. The current report illustrates the case of a 53-year-old female presenting with a history of abdominal pain (colicky) with vomiting and nausea, which required diagnostic laparoscopy plus open mesh repair of right inguinal hernia. Operative findings reveal a hernia in the right groin extended to the right labia containing fat and a segment of distal ileum that shows decreased wall enhancement with the surrounding fluid, leading to small bowel dilatation up to proximal jejunum with a maximum diameter of about five cm. This case highlights the importance of obstipation imperative to the diagnosis of small bowel obstruction due to obstructed indirect inguinal hernia.

The incidence of inguinal hernia in females is less compared to the males. Pantaloon hernia in females is even rarer and may be first diagnosed during surgery. We report a rare case of pantaloon hernia in a 60 year old female patient. She presented with reducible left groin swelling of 3 years duration and a clinical diagnosis of an indirect inguinal hernia made. A direct sac and an indirect sac were discovered at operation on both sides of the inferior epigastric artery. The posterior wall was repaired by Lichtenstein method. Patient made an uneventful recovery and there was no recurrence after 12 months of follow up. Though pantaloon hernia is rare in females, proper dissection, and identification of structure in the inguinal canal is necessary to make the correct diagnosis and to offer the appropriate treatment.

Although the laparoscopic technique is a new approach to groin hernia, it is becoming more widely accepted as an alternative to traditional open techniques. This study is a preliminary review of complications and recurrences. A questionnaire specific for complications was sent to each investigator. From 12/89 to 4/93, 1,514 hernias were repaired; 119 (7.8%) were bilateral and 192 (12.7%) recurrent. There were 860 indirect, 560 direct, 43 pantaloon, 37 femoral, and 6 obturator hernias, and 8 were not specified; 553 were repaired using a transabdominal preperitoneal mesh technique (TAPP), 457 with a total extraperitoneal technique (TEP), 320 with intraperitoneal onlay mesh (IPOM), 102 by ring closure, and 82 involved plug and patch technique. Eighteen intraoperative and 188 postoperative complications were seen. The total complication rate was 13.6%, of which 1.2% were intraoperative. Of the intraoperative complications, 12 were related to the laparoscopic technique, three were relate...

Background:laparoscopic groin hernia repair has gained wide popularity in surgical practice in the last two decades. Trans abdominal pre peritoneal (TAPP) and totally extra peritoneal (TEP) repair are standing head to head as the most common laparoscopic techniques for groin hernia. Methods:This prospective randomized study was conducted between December 2013 and December 2015. Sixty male patients suffering from non complicated inguinal hernia were included. Patients were randomized into group A (TAPP) and group B (TEP). Intra operative variables and postoperative pain and complications were recorded in a pre structured form Results:In TEP group patient had lees post operative pain, were able to resume their normal daily activities and spent less operative time than TAPP group. No significant difference in terms of Intra operative and post operative complications between both groups. Conclusion:. TEP has a significant advantages over TAPP in reduction of operative time and postoperative pain, which resulted in earlier recovery and return to normal activity. Although both techniques seem to effective, TEP has a step over TAPP.

Background Groin hernia repair is one of the most common operations performed globally, with more than 20 million procedures per year. The last guidelines on groin hernia management were published in 2018 by the HerniaSurge Group. The aim of this project was to assess new evidence and update the guidelines. The guideline is intended for general and abdominal wall surgeons treating adult patients with groin hernias. Method A working group of 30 international groin hernia experts and all involved stakeholders was formed and examined all new literature on groin hernia management, available until April 2022. Articles were screened for eligibility and assessed according to GRADE methodologies. New evidence was included, and chapters were rewritten. Statements and recommendations were updated or newly formulated as necessary. Results Ten chapters of the original HerniaSurge inguinal hernia guidelines were updated. In total, 39 new statements and 32 recommendations were formulated (16 stro...

Background: Treatment of groin hernias continues to evolve. The emergence of laparoscopic inguinal hernia surgery has challenged the conventional gold standard Lichtenstein’s tension free mesh repair. Laparoscopic technique to achieve surgical correction over groin hernia is increasingly being practiced in our country, and it is imperative to test the overall outcome of this technique in a tertiary care setting. Objectives: Current study was aimed at evaluating the per-operative events, early and late outcomes of laparoscopic groin hernia repair techniques. End points of evaluation were postoperative pain, hospital stay, resumption of normal activities, chronic pain and recurrence. Methods: Within a 2-year period, 45 patients of groin hernias of different clinical types underwent laparoscopic inguinal hernia repair in Bangladesh Medical College Hospital were recruited in this prospective observational study. Preoperative findings, intraoperative course, postoperative and follow-up d...

Background: A contralateral occult inguinal hernia is frequently observed in patients planned for a unilateral laparoscopic inguinal hernia repair. Surgical strategy for contralateral groin management in patients scheduled for an endo-laparoscopic unilateral inguinal hernia repair is controversial and based on questionable evidence. This study aimed to gather international opinion concerning the surgical strategy for the contralateral asymptomatic side when no hernia or lipoma is clinically evident at the preoperative examination or anamnesis. Methods: An international Internet-based questionnaire was sent to all the members of the European Hernia Society, the Americas Hernia Society, and the Asia Pacific Hernia Society. The clinical scenario for responders was a patient with a unilateral symptomatic inguinal hernia planned for endo-laparoscopic repair with no preoperative symptoms/lump on the contralateral side. Results: A total of 640 surgeons replied (response rate = 26%), of who...

The advantage of using minimally invasive techniques over open techniques in the repair of groin hernias is still debated. Despite its more widespread use, an apparent dichotomy exists. While some surgeons continue to believe that no advantage is gained using the laparoscopic technique, others argue laparoscopic hernia repair (LHR) offers a quicker recovery with the use of a tension-free repair. A mailing to the general surgeon members of the Society of Laparoendoscopic Surgeons, an international multidisciplinary laparoendoscopic society, was performed (mailing size = 1680). Nine hundred and ninety-three surgeons responded (60%). Across all demographic variables, 60% of respondents performed approximately 27% of their hernia repairs laparoscopically (40% of respondents did not perform LHR). Surgeon age less than 45 was the only demographic characteristic that predicted the likelihood to perform LHR (p < 0.0001) and the percentage of hernias repaired laparoscopically (p < 0.00...

The aim of this study was to assess long-term chronic pain, numbness and functional impairment after open and laparoscopic groin hernia repair in a teaching hospital. We performed a cross-sectional study in which all adult patients with a groin hernia repair between January 2000 and August 2005 received a questionnaire by post. It contained questions concerning frequency and intensity of pain, presence of bulge, numbness, and functional impairment. One thousand seven hundred and sixty-six questionnaires were returned (81.6%) and after a median follow-up period of nearly 3 years 40.2% of patients reported some degree of pain. Thirty-three patients (1.9%) experienced severe pain. Almost one-fourth reported numbness which correlated significantly with pain (P < 0.001). Other variables, identified as risk factors for the development of pain were age (P < 0.001) and recurrent hernia repair (P = 0.003). One-fifth of the patients felt functionally impaired in their work or leisure ac...

Laparoscopic inguinal herniorrhaphy was first described by Ger, Schultz, Corbitt, and Filipi in the early 1990s and burst upon the surgical scene just after laparoscopic cholecystectomy. It rapidly became popular, and many different techniques for repair were developed. Over the last decade much good work has been done to find which type of laparoscopic repair is best, to determine whether the laparoscopic or open approach is better, and to develop and refine open tension-free repairs.
