In this study, physicians from the United States compared the diagnostic yield of the Given M2A videocapsule endoscope with that of conventional push enteroscopy for obscure GI bleeding.
The team evaluated 20 consecutive patients with unidentified GI bleeding.
These patients underwent videocapsule endoscopy, and subsequent push enteroscopy.
|Identification of bleeding source:|
- videocapsule = 60%
- enteroscopy = 15%

The endoscopist was blinded to the results of the videocapsule study.
The physicians found that the videocapsule endoscopy determined the source of bleeding in 60% of patients, compared with 15% for push enteroscopy.
In addition, the videocapsule endoscopy identified the source of bleeding in 9 of 13 patients who had a negative enteroscopy.
Based on the results from the videocapsule endoscopy, 3 patients underwent surgical resections.
Dr Alan Buchman's team concluded, "The Given M2A videocapsule endoscope has superior diagnostic utility for the evaluation of gastrointestinal bleeding when compared with standard push enteroscopy".
"The Given M2A videocapsule endoscope can be used to direct appropriate therapy in addition to avoiding the use of unnecessary conventional endoscopic and radiologic procedures".
