Background: Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short-and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias. Methods: The guideline group consisted of surgeons from Europe and North America including members from the European Hernia Society and the Americas Hernia Society. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists, and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done on 1 May 2018, and updated on 1 February 2019. Results: Literature reporting specifically on umbilical and epigastric hernias was limited in quantity and quality, resulting in a majority of the recommendations being graded as weak, based on low-quality evidence. The main recommendation was to use mesh for repair of umbilical and epigastric hernias to reduce the recurrence rate. Most umbilical and epigastric hernias may be repaired by an open approach with a preperitoneal flat mesh. A laparoscopic approach may be considered if the hernia defect is large, or if the patient has an increased risk of wound morbidity. Conclusion: This is the first European and American guideline on the treatment of umbilical and epigastric hernias. It is recommended that symptomatic umbilical and epigastric hernias are repaired by an open approach with a preperitoneal flat mesh.
Background Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management. Methods The guideline group consisted of surgeons from the European and Americas Hernia Societies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used in formulating the recommendations. The Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists were used to evaluate the quality of full‐text papers. A systematic literature search was performed on 1 May 2018 and updated 1 February 2019. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was followed. Results Literature was limited in quantity and quality. A majority of the recommendations were graded as weak, based on low quality of evidence. In patients with cirrhosis or on dialysis, a preperitoneal mesh repair is suggested. Subsequent pregnancy is a risk factor for recurrence. Repair should be postponed until after the last pregnancy. For patients with a concomitant rectus diastasis or those with a Spigelian or lumbar hernia, no recommendation could be made for treatment strategy owing to lack of evidence. Conclusion This is the first European and American guideline on the treatment of umbilical and epigastric hernias in patients with special conditions, including Spigelian and lumbar hernias. All recommendations were weak owing to a lack of evidence. Further studies are needed on patients with rectus diastasis, Spigelian and lumbar hernias.
Introduction: Recently, the promising results of new procedures for the treatment of rectus diastasis with concomitant hernias using extraperitoneal mesh placement and anatomical restoration of the linea alba were published. To date, there is no recognized classification of rectus diastasis (RD) with concomitant hernias. This is urgently needed for comparative assessment of new surgical techniques. A working group of the German Hernia Society (DHG) and the International Endohernia Society (IEHS) set itself the task of devising such a classification.Materials and Methods: A systematic search of the available literature was performed up to October 2018 using Medline, PubMed, Scopus, Embase, Springer Link, and the Cochrane Library. A meeting of the working group was held in May 2018 in Hamburg. For the present analysis 30 publications were identified as relevant.Results: In addition to the usual patient- and technique-related influencing factors on the outcome of hernia surgery, a typical means of rectus diastasis classification and diagnosis should be devised. Here the length of the rectus diastasis should be classified in terms of the respective subxiphoidal, epigastric, umbilical, infraumbilical, and suprapubic sectors affected as well as by the width in centimeters, whereby W1 < 3 cm, W2 = 3− ≤ 5 cm, and W3 > 5 cm. Furthermore, gender, the concomitant hernias, previous abdominal surgery, number of pregnancies and multiple births, spontaneous birth or caesarian section, skin condition, diagnostic procedures and preoperative pain rate and localization of pain should be recorded.Conclusion: Such a unique classification is needed for assessment of the treatment results in patients with RD.
IntroductionIt is known that recurrences continue to occur after the follow-up period of 1–5 years usually used in most hernia studies. By reviewing the data in the Herniamed Hernia Registry documenting the time interval between the recurrent operation and previous inguinal hernia repair, the present study identifies the temporal course of onset of recurrence.Patients and MethodsProspective data were recorded in the Herniamed Registry between 1 September 2009 and 4 May 2015 on a total of 145,590 patients with 171,143 inguinal hernia operations. These included 18,774 operations due to an inguinal hernia recurrence (10.94%). During the same period, prospective data were collected on 24,385 incisional hernia operations. The latter cases included 5,328 patients with a recurrent incisional hernia (21.85%).ResultsOnly 57.46% of all inguinal hernia recurrences occurred within 10 years of the previous inguinal hernia operation. Some of the remaining 42.54% of all recurrences occurred only much later, even after more than 50 years. The course of onset of recurrence is markedly different for incisional hernia. About 91.87% of such recurrences occur already within 10 years of the last operation.ConclusionAscertainment of the actual recurrence rate after hernia repair calls for a follow-up of 10 years for incisional hernia and of 50 years for inguinal hernia. The data collected can be used to give an approximate estimate with a shorter follow-up.
Background: To date, there are few studies and no systematic reviews focusing specifically on groin hernia in women. Most of the existing knowledge comes from registry data. Objective: This present review now reports on such findings as are available on groin hernia in women. Materials and Methods: A systematic search of the available literature was performed in September 2018 using Medline, PubMed, Google Scholar, and the Cochrane Library. For the present analysis 80 publications were identified. Results: The lifetime risk of developing a groin hernia in women is 3–5.8%. The proportion of women in the overall collective of operated groin hernias is 8.0–11.5%. In women, the proportion of femoral hernias is 16.7–37%. Risk factors for development of a groin hernia in women of high age and with a positive family history. A groin hernia during pregnancy should not be operated on. The rate of emergency procedures in women, at 14.5–17.0%, is 3 to 4-fold higher than in men and at 40.6% is even higher for femoral hernia. Therefore, watchful waiting is not indicated in women. During surgical repair of groin hernia in females the presence of a femoral hernia should always be excluded and if detected should be repaired using a laparo-endoscopic or open preperitoneal mesh technique. A higher rate of chronic postoperative inguinal pain must be expected in females. Conclusion: Special characteristics must be taken into account for repair of groin hernia in women.
Objective: Based on an analysis of data from the Herniamed Registry, this study aims to identify all factors influencing the outcome in female groin hernia repair. Background: In a systematic review and meta-analysis of observational studies, female sex was found to be a significant risk factor for recurrence. In the guidelines, the totally extraperitoneal patch plasty (TEP) and transabdominal preperitoneal patch plasty (TAPP) laparo-endoscopic techniques are recommended for female groin hernia repair. However, even when complying with the guidelines, a less favorable outcome must be expected than in men. To date, there is no study in the literature for analysis of all factors influencing the outcome in female groin hernia repair. Methods: In all, 15,601 female patients from the Herniamed Registry who had undergone primary unilateral groin hernia repair with the Lichtenstein, Shouldice, TEP or TAPP technique, and for whom 1-year follow-up was available, were selected between September 1, 2009 and July 1, 2017. Using multivariable analyses, influencing factors on the various outcome parameters were identified. Results: In the multivariable analysis, a significantly higher risk of postoperative complications, complication-related reoperations, recurrences, and pain on exertion was found only for the Lichtenstein technique. No negative influence on the outcome was identified for the TEP, TAPP, or Shouldice techniques. Relevant risk factors for occurrence of perioperative complications, recurrences, and chronic pain were preoperative pain, existing risk factors, larger defects, a higher body mass index (BMI), higher American Society of Anesthesiologists (ASA) classification and postoperative complications. Higher age had a negative association with postoperative complications and positive association with pain rates. Conclusions: Female groin hernia repair should be performed with the TEP or TAPP laparo-endoscopic technique, or, alternatively, with the Shouldice technique, if there is no evidence of a femoral hernia. By contrast, the Lichtenstein technique has disadvantages in terms of postoperative complications, recurrences, and pain on exertion. Important risk factors for an unfavorable outcome are preoperative pain, existing risk factors, higher ASA classification, higher BMI, and postoperative complications. A higher age and larger defects have an unfavorable impact on postoperative complications and a more favorable impact on chronic pain.
IntroductionOn the basis of six meta-analyses, the guidelines of the European Hernia Society (EHS) recommend laparo-endoscopic recurrent repair following previous open inguinal hernia operation and, likewise, open repair following previous laparo-endoscopic operation. So far no data are available on implementation of the guidelines or for comparison of outcomes. Besides, there are no studies for comparison of outcomes for compliance versus non-compliance with the guidelines.Patients and methodsIn total, 4812 patients with elective unilateral recurrent inguinal hernia repair in men were enrolled between September 1, 2009, and September 17, 2014, in the Herniamed Registry. Only patients with 1-year follow-up were included.ResultsOut of the 2482 laparo-endoscopic recurrent repair operations 90.5% of patients, and out of the 2330 open recurrent repair procedures only 38.5% of patients, were operated on in accordance with the guidelines of the EHS. Besides, on compliance with the guidelines multivariable analysis demonstrated for laparo-endoscopic recurrent repair a significantly lower risk of pain at rest (OR 0.643 [0.476; 0.868]; p = 0.004) and pain on exertion (OR 0.679 [0.537; 0.857]; p = 0.001). Comparison of laparo-endoscopic and open recurrent repair in settings of compliance versus non-compliance with the guidelines showed a higher incidence of perioperative complications and re-recurrences for recurrent repairs that did not comply with the guidelines.ConclusionThe EHS guidelines for recurrent inguinal hernia repair are not yet being observed to the extent required. Non-compliance with the guidelines is associated with higher perioperative complication rates and higher risk of re-recurrence. Even on compliance with the guidelines, the risk of pain at rest and pain on exertion is higher after open recurrent repair than after laparo-endoscopic repair.
