Overview
Other Imaging Findings
Endoscopy
- Endoscopy is the most common diagnostic tool for diagnosing angiodysplasia of the GI tract.[1]
- Upper GI endoscopy and colonoscopy are usually used to diagnose upper GI and colonic angiodysplasia, respectively.
- Wireless capsule endoscopy and push enteroscopy are the common modalities for diagnosing small bowel angiodysplasia because it is difficult to reach the small bowel with traditional endoscopic techniques.
- The lesions are difficult to find but when visible, they appear as 5 to 10 mm, cherry-red, fern-like pattern of vessels.
Deep Small Bowel Enteroscopy
- Deep small bowel enteroscopy, also called intra-operative enteroscopy, includes double-balloon enteroscopy (DBE), single-balloon enteroscopy (SBE), and spiral enteroscopy (SE).
- Superior to push enteroscopy in terms of maximal length of insertion and diagnostic yield but have the risk of complications due to invasive nature.[2]
- Reserved for cases in which less invasive modalities failed to yield results.
