However, an everted VID with prolapse of ileum arising from an omphalocele is rare, and its appearance at birth can be alarming and can present a diagnostic challenge. We describe a baby born to a teenage diabetic mother who was noted to have a strange exophytic mass arising from the abdominal wall. Antenatal scans had revealed multiple other malformations but not an omphalocele. He was operated on early, and the diagnosis of a patent VID with prolapse of the ileum arising from an omphalocele was only confirmed intraoperatively. The duct was resected, the ileum closed primarily and primary closure of the abdominal wall was performed without tension. He recovered well postoperatively. A brief review of similar cases is included.<\/jats:p>","DOI":"10.1136\/bcr-2019-229971","type":"journal-article","created":{"date-parts":[[2019,6,19]],"date-time":"2019-06-19T06:49:07Z","timestamp":1560926947000},"page":"e229971","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Complete evagination of a patent vitellointestinal duct and adjacent ileal limbs from an omphalocele sac: an extreme presentation"],"prefix":"10.1136","volume":"12","author":[{"given":"Sarah Kher-ru","family":"Sim","sequence":"first","affiliation":[{"name":"Paediatric Surgery, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rambha","family":"Rai","sequence":"additional","affiliation":[{"name":"Paediatric Surgery, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anette Sundfor","family":"Jacobsen","sequence":"additional","affiliation":[{"name":"Paediatric Surgery, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,6,18]]},"reference":[{"key":"2025082723481047000_12.6.e229971.1","first-page":"116-23","article-title":"Omphalomesenteric duct malformations","volume":"5","author":"Moore","year":"1996","journal-title":"Semin Pediatr Surg"},{"key":"2025082723481047000_12.6.e229971.2","doi-asserted-by":"crossref","first-page":"619","DOI":"10.1007\/s00383-006-1699-3","article-title":"Congenital intestinal fistula with exomphalos minor","volume":"22","author":"Ng","year":"2006","journal-title":"Pediatr Surg Int"},{"key":"2025082723481047000_12.6.e229971.3","doi-asserted-by":"crossref","first-page":"30","DOI":"10.21699\/jns.v5i3.351","article-title":"Vitellointestinal duct anomalies in infancy","volume":"5","author":"Kadian","year":"2016","journal-title":"J Neonatal Surg"},{"key":"2025082723481047000_12.6.e229971.4","doi-asserted-by":"crossref","first-page":"90","DOI":"10.4174\/astr.2016.91.2.90","article-title":"Meckel diverticulum in exomphalos minor","volume":"91","author":"Sohn","year":"2016","journal-title":"Ann Surg Treat Res"},{"key":"2025082723481047000_12.6.e229971.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2005.11.013"},{"key":"2025082723481047000_12.6.e229971.6","doi-asserted-by":"crossref","first-page":"747","DOI":"10.1016\/0002-9610(53)90391-2","article-title":"Persistent omphalomesenteric duct with omphalocele","volume":"86","author":"Gratiot","year":"1953","journal-title":"Am J Surg"},{"key":"2025082723481047000_12.6.e229971.7","first-page":"254","article-title":"Patent omphalomesenteric duct and exomphalos minor: a rare and interesting association","volume":"92","author":"Chattopadhyay","year":"2007","journal-title":"Int Surg"},{"key":"2025082723481047000_12.6.e229971.8","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1016\/j.ijscr.2018.04.012","article-title":"Vitelline fistula associated with omphalocele: diagnostic dilemma?","volume":"47","author":"Sy","year":"2018","journal-title":"Int J Surg Case Rep"},{"key":"2025082723481047000_12.6.e229971.9","first-page":"715","article-title":"Omphalocele with a patent everted omphalomesenteric duct","volume":"32","author":"Allen","year":"1952","journal-title":"Surgery"},{"key":"2025082723481047000_12.6.e229971.10","doi-asserted-by":"crossref","first-page":"617","DOI":"10.1002\/bjs.18004519410","article-title":"Patent vitello-intestinal duct; the risk of obstruction due to prolapse","volume":"45","author":"Soutar","year":"1958","journal-title":"Br J Surg"},{"key":"2025082723481047000_12.6.e229971.11","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(67)90210-3"},{"key":"2025082723481047000_12.6.e229971.12","doi-asserted-by":"publisher","DOI":"10.1007\/BF02753539"},{"key":"2025082723481047000_12.6.e229971.13","doi-asserted-by":"crossref","first-page":"270","DOI":"10.4067\/S0370-41061986000300011","article-title":"diverticulo de Meckel permeable y trisomia 13 (Spanish)","volume":"57","author":"Zuniga","year":"1986","journal-title":"Rev Chil Pediatr"},{"key":"2025082723481047000_12.6.e229971.14","doi-asserted-by":"crossref","first-page":"422","DOI":"10.1007\/BF00169706","article-title":"Intussusception of vitello-intestinal tract through an exomphalos in trisomy 13","volume":"4","author":"Blair","year":"1989","journal-title":"Pediatr Surg Int"},{"key":"2025082723481047000_12.6.e229971.15","doi-asserted-by":"crossref","first-page":"e9","DOI":"10.1016\/j.jpedsurg.2013.03.073","article-title":"Esophageal atresia, small omphalocele and ileal prolapse through a patent omphalomesenteric duct: a methimazole embryopathy?
