We report a 65-year-old man who presented with acute epigastric pain, vomiting, and hematemesis 17 years after subtotal gastrectomy with retrocolic Billroth 2 reconstruction. Abdominal CT showed JGI with a target-like lesion and a whirl sign near the gastrojejunostomy, suggesting associated torsion and threatened bowel viability. Emergency laparotomy revealed extensive adhesions, 360\u00b0 clockwise torsion of the efferent loop, and efferent-loop intussusception with retrograde herniation into the remnant stomach, resulting in severe edema, incarceration, ischemia, and necrosis. After adhesiolysis, abdominal reduction was unsuccessful; therefore, gastrotomy-assisted reduction, resection of the necrotic bowel, and side-to-side jejunojejunostomy were performed. The patient recovered uneventfully and was discharged on postoperative day 10. At 6-month follow-up, he remained asymptomatic, and contrast-enhanced CT showed no recurrent torsion or intussusception. This case highlights that JGI with torsion should be considered in patients with a history of gastrectomy who develop acute abdominal pain, vomiting, or hematemesis, even many years after surgery. Prompt CT-based diagnosis and definitive surgical treatment are essential when ischemia is suspected.<\/jats:p>","DOI":"10.3389\/fsurg.2026.1812043","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T05:45:30Z","timestamp":1782279930000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A case report of jejunogastric intussusception complicated by torsion: 17 years after subtotal gastrectomy"],"prefix":"10.3389","volume":"13","author":[{"given":"Haoyu","family":"Zhu","sequence":"first","affiliation":[{"name":"The Second Clinical Medical College, Lanzhou University","place":["Lanzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Peng","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Lanzhou University Second Hospital","place":["Lanzhou, China"]},{"name":"The Second Clinical Medical College, Lanzhou University","place":["Lanzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haipeng","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Lanzhou University Second Hospital","place":["Lanzhou, China"]},{"name":"The Second Clinical Medical College, Lanzhou University","place":["Lanzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"452","DOI":"10.1097\/00004836-198908000-00021","article-title":"Jejunogastric intussusception diagnosis and management","volume":"11","author":"Wheatley","year":"1989","journal-title":"J Clin Gastroenterol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"541","DOI":"10.1097\/00007611-197905000-00012","article-title":"Retrograde jejunogastric intussusception","volume":"72","author":"Monroe","year":"1979","journal-title":"South Med J"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1449","DOI":"10.1001\/archsurg.1980.01380120023006","article-title":"Jejunogastric intussusception","volume":"115","author":"Waits","year":"1980","journal-title":"Arch Surg"},{"key":"B4","doi-asserted-by":"publisher","first-page":"407","DOI":"10.3748\/wjg.15.407","article-title":"Intussusception of the bowel in adults: a review","volume":"15","author":"Marinis","year":"2009","journal-title":"World J Gastroenterol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"105862","DOI":"10.1016\/j.ijscr.2021.105862","article-title":"A rare case of jejunogastric intussusception: a case report and review of the literature","volume":"82","author":"Abu-Omar","year":"2021","journal-title":"Int J Surg Case Rep"},{"key":"B6","doi-asserted-by":"publisher","first-page":"264","DOI":"10.1016\/j.ijscr.2017.08.036","article-title":"Antegrade jejunojejunal intussusception inside a retrograde jejunogastric intussusception (double intussusception): a rare case report","volume":"39","author":"Ravirajendran","year":"2017","journal-title":"Int J Surg Case Rep"},{"key":"B7","first-page":"4498","article-title":"Jejunogastric intussusception: a rare complication of gastric cancer surgery","volume":"7","author":"Lee","year":"2014","journal-title":"Int J Clin Exp Med"},{"key":"B8","doi-asserted-by":"publisher","first-page":"309","DOI":"10.1016\/j.asjsur.2014.04.001","article-title":"Retrograde jejunogastric intussusception: a case report and review of the literature","volume":"40","author":"Loi","year":"2017","journal-title":"Asian J Surg"},{"key":"B9","doi-asserted-by":"publisher","first-page":"834","DOI":"10.1007\/s00384-005-0789-3","article-title":"Clinical spectrum and surgical approach of adult intussusceptions: a multicentric study","volume":"21","author":"Barussaud","year":"2006","journal-title":"Int J Colorectal Dis"}],"container-title":["Frontiers in Surgery"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fsurg.2026.1812043\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T05:45:31Z","timestamp":1782279931000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fsurg.2026.1812043\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,24]]},"references-count":9,"alternative-id":["10.3389\/fsurg.2026.1812043"],"URL":"https:\/\/doi.org\/10.3389\/fsurg.2026.1812043","relation":{},"ISSN":["2296-875X"],"issn-type":[{"value":"2296-875X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,24]]},"article-number":"1812043"}}
