The current study aims to clarify the contents of pediatric IH using preoperative ultrasonography (US) in association with patient age, sex, and risk for developing irreducible\/strangulated hernia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The medical records of pediatric IH patients who underwent inguinal US examination prior to surgery between 2014 and 2019 were reviewed. Hernia contents were categorized into four groups based on US findings: bowel, omentum, ovary with or without fallopian tube, and ascites.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 524 IH lesions found in 220 men and 304 women were analyzed. The most common hernia content in patients under 12\u2009months of age was the bowel (91.0%) in males and ovaries (89.5%) in females. The omentum became the most common herniated organ in both men (78.6%) and women (88.0%) aged 2\u2009years and older. Emergency operations were performed in 3 patients (0.57%) due to irreducible IH, where 2 patients with irreducible ovaries, 5 and 7\u2009months old, developed ovarian torsion and needed to undergo emergent salpingo\u2010oophorectomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The contents of pediatric IH depended on patient age and sex. Herniated ovaries in infants can twist in the hernia sac and become strangulated. It is important for clinicians to expect the herniated organ and take appropriate measures in the pediatric primary care setting.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ped.15193","type":"journal-article","created":{"date-parts":[[2022,3,14]],"date-time":"2022-03-14T15:13:11Z","timestamp":1647270791000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Association of pediatric inguinal hernia contents with patient age and sex"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4168-167X","authenticated-orcid":false,"given":"Takahiro","family":"Ohkura","sequence":"first","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Kumori","sequence":"additional","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiko","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics Shimane University Hospital  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junko","family":"Manako","sequence":"additional","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuichi","family":"Ishibashi","sequence":"additional","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narimasa","family":"Funabashi","sequence":"additional","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshitsugu","family":"Tajima","sequence":"additional","affiliation":[{"name":"Department of Digestive and General Surgery Shimane University Faculty of Medicine  Izumo Shimane Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,6,15]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"522","article-title":"Inguinal hernias in children\u2013a study of 1,000 cases and a review of the literature","volume":"1972","author":"Bronsther B","year":"1972","journal-title":"J.
