In this setting, gastro-intestinal ultrasound has been especially used to evaluate the bowel wall features (thickening, stratification, vascularization) and complications related to IBD (fistulas, abscesses). Nevertheless, gastro-intestinal ultrasound can be also used to detect and evaluate the content of several segments of the gut. In fact, there is a growing interest in utilizing GIUS for suspected functional disorders, where assessing intestinal content may play a significant diagnostic role, as well as directing therapy. In our review, we provided a sonographic description of GIUS appearances of bowel content in various pathological and physiological conditions, offering potential applications in clinical practice and providing insights for further research.<\/jats:p>","DOI":"10.1007\/s40477-024-00951-3","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T19:35:34Z","timestamp":1726774534000},"page":"781-792","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Ultrasound assessment of gastrointestinal luminal contents: a narrative review"],"prefix":"10.1007","volume":"27","author":[{"given":"Heidi Y.","family":"Su","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirstin M.","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antony B.","family":"Friedman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Cataletti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0810-4026","authenticated-orcid":false,"given":"Giovanni","family":"Maconi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,9,18]]},"reference":[{"issue":"5","key":"951_CR1","doi-asserted-by":"publisher","first-page":"720","DOI":"10.1016\/j.ajem.2017.01.008","volume":"35","author":"J Singleton","year":"2017","unstructured":"Singleton J, Schafer JM, Hinson JS, Kane EM, Wright S, Hoffmann B (2017) Bedside sonography for the diagnosis of esophageal food impaction.
