Overview
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. Small bowel angiodysplasia can be difficult to diagnose with traditional endoscopic techniques. The lesions appear as 5 to 10 mm, cherry-red, fern-like pattern of vessels.
Other Imaging Findings
Endoscopy
- Endoscopy is the most common diagnostic tool for diagnosing angiodysplasia of the GI tract.[1][2]
- 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 has the risk of complications due to invasive nature.[3][4][5]
- Reserved for cases in which less invasive modalities failed to yield results.
