title: Gastrointestinal bleeding and intussusception due to gastrointestinal stromal tumor (GIST).
abstract: BACKGROUND
  Small bowel tumors comprise 25% of gastrointestinal (GI) neoplasms, of which only between 0.2 and 1% correspond to gastrointestinal stromal tumors (GIST). GI bleeding is the most common presentation of GIST, being responsible in 1% of the cases. This type of neoplasm can also be the origin of an intussusception, which is an infrequent process during adult age, representing only 5% of all intestinal obstructions.
  
  
  METHODS
  We report a case of a patient who arrived at the emergency department due to abdominal pain and lower GI bleeding. The diagnostic process was not conclusive. After an exploratory laparotomy, the diagnosis was GI bleeding and intussusception due to GIST.
  
  
  CONCLUSIONS
  Surgery must be the last diagnostic and therapeutic resource, but it is sometimes necessary to localize bleeding and intestinal obstruction site.
