Overview
Other diagnostic studies for small intestine cancer include fluoroscopy, which demonstrates mucosal pattern distortion, obliteration, and narrowing.
Other Diagnostic Studies
Enteroscopy
- X-ray, CT, MRI, and PET-CT are the foremost examination modalities for small intestinal tumors.
- However, with the advancement of radiology, a series of new diagnostic techniques have been developed, such as electronic enteroscopy, multi-slice spiral CT enteroclysis and capsule endoscopy. [1]
- On enteroscopy, gastrointestinal stromal tumor present as a nodule with enlarged mucosal folds or as a mass with abnormal surface vessels.
- Carcinoid tumors present with submucosal nodule or bulge, which can be associated with an ulcer.
- Lymphomas present with variable degrees of nodular mucosa and occasional ulcerations and strictures [2]
Capsule endoscopy:
- In this procedure, the patient is not detected with an actual endoscope but with a capsule (about the size of a large vitamin pill)
- Endoscope contains a light source and a very small camera.
- After swallowing, the capsule goes through the small intestine for a period of 8 hours.
- It takes thousands of pictures which can be downloaded onto a computer to analyze.
Double balloon enteroscopy
- This is a newer way of looking at the small intestine. At first the patient need to anesthesia.
- This technology makes the doctor to see the intestine a foot at a time and even take a biopsy if something abnormal.
