A woman in her 40s was admitted to Nagoya City University Hospital with fatigue, anorexia, nausea and vomiting. CT, oesophagogastroduodenoscopy and colonoscopy revealed no signs of organic abnormality in her gastrointestinal tract. As the patient had previously been diagnosed with and treated for depression, her symptoms were suspected to be due to psychogenic disorder. Therefore, she was diagnosed with severe depression and was administered antidepressant agents. Despite intense psychiatric treatment, her symptoms worsened and she was later diagnosed with ileus due to adenocarcinoma in the jejunum. After drainage by insertion of a transnasal decompression tube, a partial jejunum resection was performed. After the resection, the patient\u2019s symptoms including fatigue and depression resolved without the use of antidepressant agents.<\/jats:p>","DOI":"10.1136\/bcr-2018-227326","type":"journal-article","created":{"date-parts":[[2019,1,29]],"date-time":"2019-01-29T04:58:32Z","timestamp":1548737912000},"page":"bcr-2018-227326","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Intestinal obstruction caused by small bowel adenocarcinoma misdiagnosed as psychogenic disorder"],"prefix":"10.1136","volume":"12","author":[{"given":"Hirotada","family":"Nishie","sequence":"first","affiliation":[{"name":"Departments of Gastroenterology and Metabolism, Nagoya City University, Nagoya, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taketo","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Departments of Gastroenterology and Metabolism, Nagoya City University, Nagoya, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Ichikawa","sequence":"additional","affiliation":[{"name":"Departments of Gastroenterology and Metabolism, Nagoya City University, Nagoya, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromi","family":"Kataoka","sequence":"additional","affiliation":[{"name":"Departments of Gastroenterology and Metabolism, Nagoya City University, Nagoya, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,1,28]]},"reference":[{"key":"2025082702460167000_12.1.bcr-2018-227326.1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.21975"},{"key":"2025082702460167000_12.1.bcr-2018-227326.2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.4251\/wjgo.v3.i3.33","article-title":"Epidemiology of cancer of the small intestine","volume":"3","author":"Pan","year":"2011","journal-title":"World J Gastrointest Oncol"},{"key":"2025082702460167000_12.1.bcr-2018-227326.3","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1159\/000332043","article-title":"Small bowel adenocarcinoma presenting with refractory iron deficiency anemia -
