While the upper gastrointestinal tract is commonly affected, small intestine impactions pose significant diagnostic challenges due to nonspecific symptoms and lack of awareness of foreign body ingestion. Herein, we describe a case presenting with recurrent, unexplained abdominal pain and hematochezia. Multiple diagnostic investigations, including esophagogastroduodenoscopy and colonoscopy, conducted over several months failed to identify the underlying cause until a retrograde single-balloon enteroscopy for obscure gastrointestinal bleeding revealed a 2.3 cm fish bone embedded in the distal ileum. The successful removal of the fish bone led to the resolution of the patient\u2019s symptoms. This case highlights that foreign bodies in the small intestine can be a cause of hematochezia and emphasizes the growing importance of deep enteroscopy techniques in detecting and retrieving these foreign objects, thereby reducing the need for surgery.<\/jats:p>","DOI":"10.3390\/medicina61010030","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T12:37:19Z","timestamp":1735648639000},"page":"30","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Embedded Ileal Fish Bone Removed via Deep Enteroscopy in a Patient with Abdominal Pain and Hematochezia: A Case Report"],"prefix":"10.3390","volume":"61","author":[{"given":"Hsin-Yang","family":"Chen","sequence":"first","affiliation":[{"name":"Division of Gastroenterology, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, No. 325, Section 2, Chenggong Road, Neihu District, Taipei City 114202, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao-Feng","family":"Chang","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, No. 325, Section 2, Chenggong Road, Neihu District, Taipei City 114202, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tien-Yu","family":"Huang","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, No. 325, Section 2, Chenggong Road, Neihu District, Taipei City 114202, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9390-6180","authenticated-orcid":false,"given":"I-Hsuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, No. 325, Section 2, Chenggong Road, Neihu District, Taipei City 114202, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1055\/s-0042-100456","article-title":"Removal of foreign bodies in the upper gastrointestinal tract in adults: European Society of Gastrointestinal Endoscopy (ESGE) Clinical Guideline","volume":"48","author":"Birk","year":"2016","journal-title":"Endoscopy"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Shishido, T., Suzuki, J., Ikeda, R., Kobayashi, Y., and Katori, Y.
