The routine upper endoscopy delays the diagnosis, and most cases require multiple investigations increasing the health care burden. Case summary: A 74-year-old man presented with two months of progressively worsening postprandial bilious emesis and epigastric abdominal pain. He underwent outpatient evaluation with upper endoscopy and a computed tomographic enterography. The first endoscopy did not enable us to recognize the small bowel mass, leading to a diagnostic delay of two months. He subsequently developed a complete intestinal obstruction. A Second look upper endoscopy done with a push enteroscopy showed an apple core-like mass suggestive of a possible malignant neoplasm at the distal duodenum\/proximal jejunum. Conclusion: Therefore, more sensitive, and specific diagnostic modalities like push enteroscopy, capsule endoscopy, and deep enteroscopy should be considered in case upper endoscopy is not conclusive.<\/jats:p>","DOI":"10.55729\/2000-9666.1195","type":"journal-article","created":{"date-parts":[[2023,6,29]],"date-time":"2023-06-29T10:42:35Z","timestamp":1688035355000},"source":"Crossref","is-referenced-by-count":1,"title":["Case Report of a Missed Small Bowel Adenocarcinoma on an Upper Endoscopy-A Review of Small Bowel Diagnostic Modalities"],"prefix":"10.55729","volume":"13","author":[{"given":"Avleen","family":"Kaur","sequence":"first","affiliation":[{"name":"Internal Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Mujtaba","family":"Baqir","sequence":"additional","affiliation":[{"name":"Internal Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunal","family":"Patel","sequence":"additional","affiliation":[{"name":"Internal Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaveh","family":"Zivari","sequence":"additional","affiliation":[{"name":"Gastroenterology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34701","published-online":{"date-parts":[[2023,6,28]]},"container-title":["Journal of Community Hospital Internal Medicine Perspectives"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/scholarlycommons.gbmc.org\/cgi\/viewcontent.cgi?article=1195&amp;context=jchimp","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T10:01:32Z","timestamp":1788602492000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.gbmc.org\/jchimp\/vol13\/iss4\/14"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,6,28]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2023,6,28]]}},"URL":"https:\/\/doi.org\/10.55729\/2000-9666.1195","relation":{},"ISSN":["2000-9666"],"issn-type":[{"value":"2000-9666","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,6,28]]}}}
