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.

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.

In our opinion, the hospital discharge data (diagnosis related group [DRG] statistics) that provide the basis for the analysis (1) are not sufficiently suitable for assessing the actual morbidity and mortality after herniotomies. Most hernias are found in the catalogue of outpatient procedures according to §115b SGB [German Social Code Book] V. Outpatient hernia repairs account for about 20% of all hernia repairs in Germany (2). Similarly, the different surgical techniques with their completely different risk profiles were not taken into account. Primary hernias can differ enormously and are therefore difficult to represent in the DRG system (3). In some instances, more than 60 different surgical procedures are subsumed under one DRG, but in Europe, there are only three or four different ways of coding herniotomies in DRGs on average. This does not seem sufficient for generating relevant data (4). The authors’ conclusion that the preoperative identification of risk could be optimized is consequently only partly valid. In the DRG-based analysis, it is impossible to differentiate between elective procedures and emergency operations. A highly acute incarcerated hernia, which according to the literature presents itself in about 5% of all cases (2), requires immediate action and is associated with substantially higher fatality rate than an elective procedure, which allows for individual preoperative optimization, as suggested. However, in rare cases, so-called watchful waiting is associated with a higher risk for hernia patients, but results in a different DRG classification in inpatients, which is not taken into account in the presented data. It is our view that the DRG system as a hospital reimbursement system that was introduced in the context of an economy drive in Germany’s healthcare system (3) still does not allow valid conclusions about clinical procedures, despite many attempts to optimize it. In our opinion, hernia registries are a more appropriate instrument.

Introduction It 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 Methods Prospective 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%). Results Only 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. Conclusion Ascertainment 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.

The survey shows the frequency and distribution of diseases evaluated by electroophthalmological methods. Patients with retinal diseases (51.2%) and those with diseases of the optic nerve (21.8%) were examined most frequently. In a high percentage these investigations lead to a clinically useful assessment: described as confirmation or exclusion of a clinical diagnosis, as establishing a possible differential diagnosis or clearing up formerly unknown aspects of a disease. In cases of hereditary retinal disorders only 11% remained unclear, with presumed optic neuritis only 6%. The importance of electroophthalmological investigations is there ability to assess functional deficits in the visual system especially in somehow more rare retinal and centrally located disorders, functional deficits of unknown origins or in general diseases including the visual system.

Electroretinal and electrocortical potentials evoked by reversing checkerboards (PERG, PVECP) were simultaneously recorded in diseases of the central retina (10 patients) and in tumor-related optic nerve disorders (11 patients) exhibiting comparable P-100 delays in the PVECP. Retinal diseases showed a peak-time delay both in the PERG and in the PVECP, while optic nerve disorders revealed no delay in the PERG. Thus, simultaneous recording of PERG and PVECP may differentiate retinal from postretinal disorders of the visual system. The method also may provide information about the site of an underlying disorder in cases of visual disturbance without obvious changes of the ocular fundus.
