She was known to have seropositive rheumatoid arthritis. Importantly, she was treated surgically for complex jejunal atresia and duplication surgery, when she was 6 days old. CT scan showed intestinal obstruction secondary to intussception. Patient had lapartomy and operative findings revealed side-to-side anastomosis with gut duplication 10\u2009cm distal to duodenal jejunum junction (due to her previous surgery during infancy). Redundant part of the loop dilated up to 300\u2009mL with large hard stone (4\u00d73.5 cm) was excised. Patient recovered well postoperatively and was discharged to go home. To our knowledge, this is the first case report to show formation of large stone 60 years after surgical treatment of complex jejunal atresia and duplication surgery in infancy.<\/jats:p>","DOI":"10.1136\/bcr-2019-231992","type":"journal-article","created":{"date-parts":[[2020,1,9]],"date-time":"2020-01-09T04:55:24Z","timestamp":1578545724000},"page":"e231992","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Calcified stone in intestinal blind loop after 60 years of surgical treatment of complex jejunal atresia: an attempt to understand an enigma"],"prefix":"10.1136","volume":"13","author":[{"given":"Syed H","family":"Raza","sequence":"first","affiliation":[{"name":"Department of Surgery, Milton Keynes University Hospital NHS Foundation Trust, Milton Keynes, Buckinghamshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elamin","family":"Elshaikh","sequence":"additional","affiliation":[{"name":"Department of Surgery, Milton Keynes University Hospital NHS Foundation Trust, Milton Keynes, Buckinghamshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed H","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Medicine and HIV Metabolic Clinic, Milton Keynes University Hospital NHS Foundation Trust, Milton Keynes, Buckinghamshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mazhar","family":"Raja","sequence":"additional","affiliation":[{"name":"Department of Surgery, Milton Keynes University Hospital NHS Foundation Trust, Milton Keynes, Buckinghamshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,1,8]]},"reference":[{"key":"2025082801403549000_13.1.e231992.1","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.133.5.490"},{"key":"2025082801403549000_13.1.e231992.2","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1055\/s-2002-32726","article-title":"Trends in the management and outcome of jejuno-ileal atresia","volume":"12","author":"Kumaran","year":"2002","journal-title":"Eur J Pediatr Surg"},{"key":"2025082801403549000_13.1.e231992.3","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1016\/j.jpedsurg.2008.10.043","article-title":"Decreased mortality but increased morbidity in neonates with jejunoileal atresia; a study of 114 cases over a 34-year period","volume":"44","author":"Stollman","year":"2009","journal-title":"J Pediatr Surg"},{"key":"2025082801403549000_13.1.e231992.4","doi-asserted-by":"crossref","first-page":"417","DOI":"10.1016\/j.jpedsurg.2018.05.003","article-title":"Primary versus secondary anastomosis in intestinal atresia","volume":"54","author":"Hillyer","year":"2019","journal-title":"J Pediatr Surg"},{"key":"2025082801403549000_13.1.e231992.5","first-page":"1","article-title":"Large enterolith complicating a Meckel diverticulum causing obstructive ileus in an adolescent male patient","volume":"2017","author":"Nastos","year":"2017","journal-title":"Case Rep Surg"},{"key":"2025082801403549000_13.1.e231992.6","first-page":"24","article-title":"Obstructing enterolith as presenting feature in Crohn's disease","volume":"22","author":"Shah","year":"2003","journal-title":"Indian J Gastroenterol"},{"key":"2025082801403549000_13.1.e231992.7","doi-asserted-by":"crossref","first-page":"240","DOI":"10.4103\/TROG_20113203_240","article-title":"Roux loop obstruction by an enterolith formation around migrated endobiliary stent","volume":"32","author":"Gupta","year":"2011","journal-title":"Trop Gastroenterol"},{"key":"2025082801403549000_13.1.e231992.8","doi-asserted-by":"crossref","first-page":"10","DOI":"10.5334\/jbsr.1456","article-title":"Small bowel obstruction due to enterolith in a patient with diffuse jejuno-ileal diverticulosis","volume":"102","author":"Fourneau","year":"2018","journal-title":"J Belg Soc Radiol"},{"key":"2025082801403549000_13.1.e231992.9","first-page":"1","article-title":"Primarily proximal jejunal stone causing enterolith ileus in a patient without evidence of Cholecystoenteric fistula or jejunal diverticulosis","volume":"2016","author":"Abtar","year":"2016","journal-title":"Case Rep Surg"},{"key":"2025082801403549000_13.1.e231992.10","doi-asserted-by":"crossref","first-page":"W49","DOI":"10.1308\/147870804119","article-title":"Tamvakopoulos GS1, Sams V, Preston P, Stebbings WS.Iron-deficiency anaemia caused by an enterolith-filled jejunal duplication cyst","volume":"86","year":"2004","journal-title":"Ann R Coll Surg Engl"},{"key":"2025082801403549000_13.1.e231992.11","doi-asserted-by":"crossref","unstructured":"Hubbard TJE , Balasubramanian R , Smith JJ .
