[Severe lower gastrointestinal bleeding due to GIST tumor. Radiological embolization and surgery]

Gastrointestinal stromal tumors (GIST) were identified only recently. These tumors usually have no symptoms, although they are localized, operable and curable. Although rare, if they are not diagnosed and treated early, they become very aggressive. The most common manifestation is gastrointestinal bleeding from mucosal erosion. Their presentation as severe lower gastrointestinal bleeding is exceptional.

We report a patient with severe lower gastrointestinal bleeding stabilized by interventional radiology that subsequently required surgery for definitive care.

Therapeutic use of radiological embolization is increasingly widespread in bleeding at various levels, achieving hemodynamic stabilization of patients. However, it must be kept in mind that, in cases of unknown etiology of lower gastrointestinal bleeding, possible causes must be investigated.
