Core Tip
Core tip: This study sample is the largest of its kind, and this article includes a detailed report on the patients with small bowel gastrointestinal stromal tumors (GISTs) based on digital subtraction angiography (DSA) visualization. The data indicate that an exact location can be determined and a diagnosis of the small bowel GISTs can be made even in patients undergoing emergency interventional DSA for obscure gastrointestinal bleeding. For cases of severe anemia, these patients can also tolerate interventional DSA and management. Therefore, interventional DSA is an alternative effective imaging modality for locating and diagnosing small bowel GISTs, even in patients with bleeding.
