title: Preoperative diagnosis of obscure gastrointestinal bleeding due to a GIST of the jejunum: a case report.
abstract: Gastrointestinal stromal tumours are rare mesenchymal neoplasms affecting the digestive tract or nearby structures within the abdomen. We present a case of a 66-year-old female patient who presented with obscure anemia due to gastrointestinal bleeding and underwent exploratory laparotomy during which a large gastrointestinal stromal tumour of the small intestine was discovered. Examining the preoperative results of video capsule endoscopy, computed tomography, and angiography and comparing them with the operative findings we discuss which of these investigations plays the most important role in the detection and localization of gastrointestinal stromal tumours. A sort review of the literature is also conducted on these rare mesenchymal tumours.
