--- abstract: 'Gastrointestinal stromal tumors (GIST) are relatively rare tumors of gastrointestinal (GI) tract, most commonly arise from the stomach followed by small intestine and colon, clinically GIST present with occult GI bleeding, abdominal pain and intestinal obstruction. We present a case of a jejunal GIST, which presented as an obscure GI haemorrhage. This case highlights how oesophagogastrodudenectomy and colonoscopy proved inconclusive in determining source of bleeding and the importance of RBC labeled 99m-Tc scan in detecting the source of GI bleeding and also emphasizes on histopathology and immunohistochemistry in diagnosis of GIST' altloc: - http://www.ojhas.org/issue35/2010-3-21.htm chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - dr.pkshetty@gmail.com - ~ - ~ - ~ creators_name: - family: Shetty given: Prasad K honourific: '' lineage: '' - family: Baliga given: Sameer V honourific: '' lineage: '' - family: K given: Balaiah honourific: '' lineage: '' - family: S given: Gnana Prakash honourific: '' lineage: '' date: 2010-10-15 date_type: published datestamp: 2010-11-22 14:19:00 department: ~ dir: disk0/00/00/71/22 edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: - Kakkilaya BS editors_name: - family: Kakkilaya given: Srinivas honourific: Dr. lineage: '' eprint_status: archive eprintid: 7122 fileinfo: /style/images/fileicons/application_pdf.png;/7122/1/2010%2D3%2D21.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: Gastrointestinal stromal tumor; RBC labeled 99m-Tc scan; Immunohistochemistry lastmod: 2011-03-11 08:57:48 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 3 pagerange: ~ pubdom: TRUE publication: Online Journal of Health and Allied Sciences publisher: Dr. B.S.
