Abstract
OBJECTIVES The groin is a complex anatomic region that has traditionally been ignored by radiologists because most lesions can be diagnosed from clinical data and physical examination. Nevertheless, ultrasound examinations of the groin are increasingly being requested to confirm injury or to resolve diagnostic uncertainty. On the other hand, some conditions involving the groin are found only in pediatric patients. This article describes the key imaging findings in pediatric groin injuries, placing special emphasis on the ultrasound appearance. CONCLUSIONS Knowledge about conditions that can affect the groin in pediatric patients and the key imaging findings associated with them helps improve the diagnostic performance of ultrasound.

Abstract
We evaluated and compared the diagnostic potential of computed tomography (CT) and herniography in the identification of inguinal hernias. Herniography is typically utilized in the diagnosis of inguinal hernias in our institute. We utilized transabdominal preperitoneal repair in the treatment of inguinal hernias since October 2010 and performed a laparoscopic diagnosis followed by single-incision laparoscopic surgery for totally extraperitoneal repair since November 2013. We herein evaluated and compared the diagnostic potential of CT and herniography. From February 2012 to March 2016, 46 patients (male/female: 43/3; median age: 70 years) with 63 inguinal hernias were investigated using CT and herniography. We classified each inguinal hernia according to the Japan Hernia Society classification using CT (prone position) and herniography, and evaluated the accuracy of each of the diagnostic methods. A total of 29 patients had unilateral hernias and 17 had bilateral hernias; 62% (39/63) and 84% (53/63) of the inguinal hernias were correctly diagnosed and classified by CT and herniography, respectively. A total of 87% (55/63) and 98% (62/63) of the inguinal hernias were detected by CT and herniography, respectively. Thus, herniography was found to be more sensitive than CT and the difference in the detectability of inguinal hernias by the 2 methods was statistically significant. Herniography appears to be superior to CT, for both the classification and detection of inguinal hernias.

Abstract
The European Hernia Society (EHS) is proud to present the EHS Guidelines for the Treatment of Inguinal Hernia in Adult Patients. The Guidelines contain recommendations for the treatment of inguinal hernia from diagnosis till aftercare. They have been developed by a Working Group consisting of expert surgeons with representatives of 14 country members of the EHS. They are evidence-based and, when necessary, a consensus was reached among all members. The Guidelines have been reviewed by a Steering Committee. Before finalisation, feedback from different national hernia societies was obtained. The Appraisal of Guidelines for REsearch and Evaluation (AGREE) instrument was used by the Cochrane Association to validate the Guidelines. The Guidelines can be used to adjust local protocols, for training purposes and quality control. They will be revised in 2012 in order to keep them updated. In between revisions, it is the intention of the Working Group to provide every year, during the EHS annual congress, a short update of new high-level evidence (randomised controlled trials [RCTs] and meta-analyses). Developing guidelines leads to questions that remain to be answered by specific research. Therefore, we provide recommendations for further research that can be performed to raise the level of evidence concerning certain aspects of inguinal hernia treatment. In addition, a short summary, specifically for the general practitioner, is given. In order to increase the practical use of the Guidelines by consultants and residents, more details on the most important surgical techniques, local infiltration anaesthesia and a patient information sheet is provided. The most important challenge now will be the implementation of the Guidelines in daily surgical practice. This remains an important task for the EHS. The establishment of an EHS school for teaching inguinal hernia repair surgical techniques, including tips and tricks from experts to overcome the learning curve (especially in endoscopic repair), will be the next step. Working together on this project was a great learning experience, and it was worthwhile and fun. Cultural differences between members were easily overcome by educating each other, respecting different views and always coming back to the principles of evidence-based medicine. The members of the Working Group would like to thank the EHS board for their support and especially Ethicon for sponsoring the many meetings that were needed to finalise such an ambitious project.

Abstract
BACKGROUND The modern concept of type-related individualized groin hernia surgery imposes a demand for precise and accurate preoperative determination of the type of groin hernia. The aim of this prospective study was to evaluate the accuracy of ultrasonography in classification of groin hernias, according to the criteria of the unified classification system. Unified classification divides groin hernias into nine types (grades): type I (indirect, small), II (indirect, medium), III (indirect, large), IV (direct, small), V (direct, medium), VI (direct, large), VII (combined-pantaloon), VIII (femoral), and O (other). PATIENTS AND METHODS One hundred and twenty-five adult patients with clinically diagnosed or suspected groin hernias were examined. Ultrasonography of both groins was performed with a 5 to 10-MHz linear-array transducer. Preoperative ultrasonographic findings of type of groin hernia were compared with the intraoperative findings, which were considered the gold standard. RESULTS Total accuracy of ultrasonography in determination of type of groin hernia was 96% (119 of 124 correct predictions of type of groin hernia compared with surgical explorations). All hernias of types I, IV, V, VII, and VIII were correctly identified with ultrasonography (sensitivity and specificity 100%). In the remaining five cases of the 124 (4%), hernia was incorrectly classified with ultrasonography: type VI (direct, large) was misdiagnosed as type III (indirect, large) in three cases, type III as type VI in one case, and type III as type II (indirect, medium) in one case. The sensitivity and the specificity of ultrasonography in classifying type II were 100 and 99%, respectively, for type III, 85 and 97%, and for type VI, 90 and 99%. CONCLUSION Ultrasonography of the groin regions could be used with great accuracy for precise classification of groin hernias in adults. Each type of groin hernia, according to the unified classification system that we used for classification, has a characteristic ultrasonographic presentation, which is demonstrated in this study.

Abstract
OBJECTIVE The purpose of our study was to investigate the CT findings of femoral hernias, focusing on their differentiation from inguinal hernias. MATERIALS AND METHODS We reviewed the records of 46 femoral hernias in seven centers (review of femoral hernias) and those of 215 groin hernias (femoral hernias, 11; inguinal hernias, 204) in one center (review of groin hernias). We evaluated the presence of hernia, extent of hernia sac based on the relationship between the hernia sac and the pubic tubercle (localized sac: sac was localized lateral to the pubic tubercle; or extended sac: sac extended medial to the pubic tubercle), and compression of the femoral vein on CT images. The chi-square test was used to assess the relationship between the CT findings and femoral versus inguinal hernias in the review of groin hernias. RESULTS In the review of 46 femoral hernias, the lesions were detected on CT in 45. In the 45 lesions, all hernia sacs were localized, and 42 lesions showed venous compression. In the review of 215 groin hernias, all 11 femoral hernias had localized sacs with venous compression on CT. Of the 204 inguinal hernias, 98 lesions were detected on CT, 65 had extended sacs, and only 10 showed venous compression. Localized sacs with venous compression were seen much more often in the femoral hernias (11/11, 100%) than in the inguinal hernias (1/92, 1.1%) (p < 0.0001). CONCLUSION CT images are useful to differentiate femoral hernias from inguinal hernias.

Abstract
Sonography and MR imaging should be considered complementary rather than competing modalities. They demonstrate similar abnormalities of the soft tissues, but MR imaging is able to demonstrate intraosseous and articular abnormalities and offers a better anatomic overview because of its larger field of view, whereas sonography offers dynamic evaluation and can provide real-time guidance for percutaneous procedures. Both of these modalities have roles in the imaging evaluation of injuries in and around the hip.

Abstract
Laparoscopic instead of open surgical repair of inguinal hernias is becoming more frequent. Radiologists may expect different postoperative findings depending on the technique used. We studied how radiology had been used postoperatively and what findings were encountered after laparoscopic herniorraphy. Postoperative radiologic examinations related to hernia repair of all consecutive patients that had had laparoscopic herniorraphy in Malmö University hospital between 1992 and 1998 were retrospectively evaluated. A total of 538 groins were included, 3.9% (n=21) of these were postoperatively examined with ultrasound (n=10), herniography (n=7), plain abdominal films (n=2), CT (n=1), or fistulography (n=1). Significant findings were found in five groins, namely, one sinus tract, two hematomas, one small bowel obstruction, and one recurrence of hernia. Four insignificant seromas were found. The characteristics of the findings and pitfalls are described. Symptoms resulting in radiologic examination are rare after laparoscopic herniorraphy. The radiologist must be familiar with the spectrum of such findings.

Abstract
BACKGROUND The aim of this prospective clinical study was to determine whether the presence of a hernia, its size, and its type can be established preoperatively by clinical and ultrasound, examination. METHODS The study population comprised 220 consecutive patients referred to our department for the surgical management of an inguinal hernia. On admission, both inguinal regions were examined clinically and by ultrasound. All patients were operated on laparoscopically. RESULTS In regard to the intraoperative findings for both inguinal regions, clinical and ultrasound examination for the diagnosis of inguinal hernia yielded a high total rate of accuracy of 93% respective 94%. However, when the same methods were used to differentiate between lateral and medial hernia, the total rate of accuracy fell to only 54% respective 62%. In the determination of inguinal hernia size, it was even lower: 50% respective 53%. CONCLUSIONS Although a diagnosis of inguinal hernia can be established reliably by clinical and ultrasound examination, only an approximate classification is possible by these methods.

Abstract
Sonography and CT are effective tools in early diagnosis of asymptomatic inguinal hernia. Sonography can be used not only for the diagnosis of hernia but also for its treatment. Real-time sonographically guided hernia reduction may avoid tissue damage that can arise from misguided compression. We report a unique case in which an incarcerated omental hernia in a 50-year-old woman was diagnosed and subsequently reduced via compression with an ultrasound transducer.

Abstract
The classification of abdominal wall hernias is often made difficult by confusing eponymous and anatomic nomenclature. In this article, we review the anatomy that defines the various types of hernias. The specific cross-sectional radiologic features required to correctly identify each type are then emphasized. The appropriate clinical context and the merits of the various imaging techniques available for the investigation of abdominal wall hernias are also discussed.
