Difficulties and possibility of preoperative diagnosis of tumor of jeonum complicated by recurrent bleeding with severe blood loss

Recurrent gastrointestinal bleeding represents a serious problem in urgent surgery due to the difficult diagnostics of the source of bleeding and high mortality. The literature describes isolated cases of bleeding from neoplasms of the small intestine. Today in clinical practice there is not a single method that has 100% diagnostic value. A rare clinical case of preoperative diagnosis of the source of recurrent intestinal bleeding using contrast-enhanced computed tomography is reviewed. This clinical case highlights the difficulties and possibility of objective preoperative diagnosis of the source of bleeding in the jejunum, using a method that is not mandatory for this purpose, which can improve patient treatment outcomes
