Computed tomography (CT) aids in diagnosing SBO by identifying transition points and potential etiologies, though accuracy varies. SBO in a virgin abdomen (SBO-VA) presents unique diagnostic challenges. This study assesses CT accuracy in identifying SBO-VA etiologies in patients at a tertiary military treatment facility to help guide future management strategies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study reviewed SBO-VA cases from 2005-2021 with IRB approval.

CT imaging showed 100% sensitivity for confirming obstruction and localizing a transition point. Diagnostic accuracy varied by etiology: sensitivity was highest for foreign bodies (100%). Strictures had a high sensitivity as well (80%), with a PPV (1.0) and specificity (100%) for foreign body, mass, and strictures. Among 17 non-operatively managed patients, adhesive disease was the most commonly presumed cause (56%), followed by partial obstruction or ileus (25%) with malignancy suspected in 2 (12%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CT reliably identifies SBO and transition points but has variable accuracy in determining specific etiologies, underscoring the need for clinical judgment in nonoperative vs operative management in patients with SBO-VA.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/00031348251397591","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T10:28:52Z","timestamp":1763029732000},"page":"1525-1531","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Accuracy of Computed Tomography in Identifying the Etiology of Small Bowel Obstructions in Virgin Abdomens at a Tertiary Care Military Treatment Facility"],"prefix":"10.1177","volume":"92","author":[{"given":"Vera M.","family":"Funk","sequence":"first","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mason H.","family":"Remondelli","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Dinoto","sequence":"additional","affiliation":[{"name":"The Walter Reed National Military Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenna","family":"Chen","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6460-5781","authenticated-orcid":false,"given":"Dylan","family":"Nun","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Morell","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Wang","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia K.","family":"Barzanji","sequence":"additional","affiliation":[{"name":"The Walter Reed National Military Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan C.","family":"Bartel","sequence":"additional","affiliation":[{"name":"The Walter Reed National Military Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick F.","family":"Walker","sequence":"additional","affiliation":[{"name":"The Walter Reed National Military Medical Center"},{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rathnayaka M.K.D.","family":"Gunasingha Bailey","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolyn E.","family":"Gosztyla","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew J.","family":"Bradley","sequence":"additional","affiliation":[{"name":"The Uniformed Services University of the Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,11,13]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13017-021-00379-8"},{"issue":"3","key":"e_1_3_5_3_2","first-page":"177","article-title":"Small bowel obstruction: a prognostic score index for surgery - a review","volume":"17","author":"Coco D","year":"2022","unstructured":"Coco D, Leanza S, Fiume I.
