Standard diagnostic techniques for small bowel malignancies
Endoscopy (upper GI endoscopy, colonoscopy, push-enteroscopy [PE]), barium studies, computed tomography (CT), and in selected cases angiography are the standard techniques that can be used for the diagnosis of small bowel malignancies.
Capsule endoscopy in the diagnosis of small bowel malignancies
Capsule endoscopy (CE) has the potential to explore the entire small bowel; therefore, it has a theoretical advantage over PE, which can only explore the jejunum, as well as over SBFT and enteroclysis, which are unsuitable to detect small mucosal lesions, especially in the distal ileum. So far, only one study, published in abstract form, was aimed specifically at evaluating the diagnostic yield of CE [6] for small bowel tumors. This is a retrospective study of 100 patients studied with CE; in
Summary
CE is an exciting new tool for the diagnosis of small bowel diseases. As far as the diagnosis of tumors is concerned, we have only begun to explore the potential of this technique. New studies are badly needed to establish the usefulness of CE in the diagnosis and management of small bowel malignancies. Such studies should help establishing the most appropriate place for CE in this setting.

2014, Gastrointestinal EndoscopyCitation Excerpt :CE is a safe and noninvasive test for study of the entire small bowel, which is both well-accepted by patients and effective in diagnosing small-bowel disease. The small-bowel tumor detection rate for CE has ranged from 2% to 9% in patients mainly presenting with GI bleeding.4,34-37 When the National Cancer Institute's Surveillance, Epidemiology, and End Results Program 9 Incidence database was used, the average annual age-adjusted incidence of small-bowel cancer nearly doubled from 11.8 cases per million in 1973 to 22.7 cases per million in 2004, after the introduction of CE.38
