Jejunal Gastrointestinal Stromal tumor (GIST) (10 of 86)

Small bowel examination can be accomplished with
standard small bowel follow-through, enteroclysis, push
enteroscopy, Sonde enteroscopy, wireless capsule
endoscopy, and intraoperative enteroscopy. In the case
described here, small bowel follow-through examination
was nondiagnostic most likely because the jejunal lesion
was predominantly extramucosal. This case also illustrates
that in young patients with obscure small intestinal bleeding
the source is frequently tumors rather than arteriovenous
malformations. These tumors are problematic because they
often grow in an extraluminal direction and only cause
intermittent bleeding if they erode or ulcerate through the
small bowel mucosa, as occurred in this patient. In a
situation such as this, a noninvasive test, such as a
computed tomography scan, may obviate the need for more
invasive testing.
