It may cause severe pain, mimicking an acute abdomen, but is typically self-limited and does not require hospitalisation or surgery. As a type of intraperitoneal focal fat infarction, it shares many of the same physiological, clinical and radiological features of epiploic appendagitis. To our knowledge, F-FLAT has not previously been reported in a patient following a laparoscopic Roux-en-Y gastric bypass surgery. Identifying falciform ligament appendagitis is critical because it can prevent unnecessary hospitalisation, follow-up studies and surgery.<\/jats:p>","DOI":"10.1136\/bcr-2020-235642","type":"journal-article","created":{"date-parts":[[2020,8,18]],"date-time":"2020-08-18T02:21:54Z","timestamp":1597717314000},"page":"e235642","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Falciform ligament appendagitis after Roux-en-Y bypass surgery mimicking acute cholecystitis"],"prefix":"10.1136","volume":"13","author":[{"given":"Lee K","family":"Rousslang","sequence":"first","affiliation":[{"name":"Department of Radiology, Tripler Army Medical Center, Medical Center, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"McHuy F","family":"McCoy","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tripler Army Medical Center, Medical Center, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C Frank","family":"Gould","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tripler Army Medical Center, Medical Center, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,8,17]]},"reference":[{"key":"2025082701564056000_13.8.e235642.1","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1159\/000484528","article-title":"Unusual Cause of Epigastric Pain: Intra-Abdominal Focal Fat Infarction Involving Appendage of Falciform Ligament - Case Report and Review of Literature","volume":"25","author":"Indiran","year":"2018","journal-title":"GE Port J Gastroenterol"},{"key":"2025082701564056000_13.8.e235642.2","doi-asserted-by":"crossref","first-page":"e531","DOI":"10.1016\/j.crad.2014.08.020","article-title":"Perigastric appendagitis: CT and clinical features in eight patients","volume":"69","author":"Justaniah","year":"2014","journal-title":"Clin Radiol"},{"key":"2025082701564056000_13.8.e235642.3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2015\/293491","article-title":"Torsion of fatty appendage of falciform ligament: acute abdomen in a child","volume":"2015","author":"Maccallum","year":"2015","journal-title":"Case Rep Radiol"},{"key":"2025082701564056000_13.8.e235642.4","doi-asserted-by":"publisher","DOI":"10.1007\/s003300000570"},{"key":"2025082701564056000_13.8.e235642.5","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/j.radcr.2019.11.004","article-title":"Fatty-falciform ligament appendage torsion (F-FLAT): diagnosis and management in a pediatric patient","volume":"15","author":"Horak","year":"2020","journal-title":"Radiol Case Rep"},{"key":"2025082701564056000_13.8.e235642.6","doi-asserted-by":"crossref","first-page":"637","DOI":"10.1016\/j.diii.2013.01.016","article-title":"Torsion of a fatty fringe of the falciform ligament, a rare cause of right hypochondrial pain","volume":"94","author":"Uyttenhove","year":"2013","journal-title":"Diagn Interv Imaging"},{"key":"2025082701564056000_13.8.e235642.7","doi-asserted-by":"crossref","first-page":"252","DOI":"10.1111\/j.1440-1673.2006.01573.x","article-title":"Primary torsion of the falciform ligament: computed tomography and ultrasound findings","volume":"50","author":"Lloyd","year":"2006","journal-title":"Australas Radiol"},{"key":"2025082701564056000_13.8.e235642.8","unstructured":"Swienton D , Shah SV .
