Among SBCs, small bowel adenocarcinoma (SBA) accounts for 30-40 % and is predominantly found in the duodenum, while jejunal and ileal presence considered rare.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>We have presented a case of jejunal adenocarcinoma in a patient with obstruction symptoms. Prior to the obstruction, the patient mainly suffered from weakness and weight loss, in addition to iron deficiency anemia. During the investigation of underlying causes, we observed evidence of mass. However, before any additional evaluation could take place, the obstruction necessitated surgical intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>Small bowel adenocarcinomas, particularly in the jejunum and ileum, are exceedingly rare and often present with complications such as obstruction, gastrointestinal bleeding, or perforation. Due to the non-specific symptoms, SBAs are challenging to diagnose before complications occur. SBAs are frequently diagnosed at advanced stages, so early diagnosis is crucial, as it can significantly impact patient survival. Thus, efforts should be made to expedite the diagnosis process to avoid complications and improve survival rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>SBAs are a rare condition, often diagnosed by related complications. Recognizing the importance of early diagnosis and its positive influence on patient survival, physicians and surgeons should consider SBA in patients presenting with relevant symptoms or cases of obstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2024.109372","type":"journal-article","created":{"date-parts":[[2024,2,14]],"date-time":"2024-02-14T00:32:58Z","timestamp":1707870778000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Jejunal adenocarcinoma; a case report and literature review"],"prefix":"10.1097","volume":"116","author":[{"given":"Hamed","family":"Tahmasbi","sequence":"first","affiliation":[{"name":"Department of General Surgery, Imam Hosein Medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parvin","family":"Kashani","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Imam Hosein medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alireza","family":"Haghbin Toutounchi","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Imam Hosein Medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaghayegh","family":"Sadeghmousavi","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Imam Hosein Medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arman","family":"Hasanzade","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Imam Hosein Medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Aghaei","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Imam Hosein Medical and Educational Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"issue":"2","key":"R1-57-20260326","doi-asserted-by":"crossref","first-page":"1223","DOI":"10.3390\/curroncol29020104","article-title":"Small bowel adenocarcinoma: from molecular insights to clinical management","volume":"29","author":"Gelsomino,","year":"2022","journal-title":"Curr.
