capsule endoscopy opened a new chapter in the study of small bowel diseases
allowing, finally, to cross the frontier of the endoscopic examination of the small
bowel. However, the global miss rate of capsule endoscopy is about 11%. To
date, there no study showed the difference between the blue mode and normal
mode (while light) in diagnosis of small bowel lesions. Our aim is to compare
between blue mode as a new method and normal mode viewings for detection
and visualization of vascular and non-vascular lesions of small bowel. Materials
and Methods: A total 20 patients with liver cirrhosis prospectively included. All
patients have small bowel mucosal lesions compatible with portal hypertensive
enteropathy detected by using normal mode viewing (RAPID reader software,
version 5 - Given Imaging, Yoqneam, Israel). We restudied the patients again
using blue mode viewing, and then we compared the results with those of
normal mode. Both mode viewings have the same speed (8 frames/ sec), and
same image resolution factors such as brightness and darkness. Results: The
vascular lesions included red spots, angioectasias, and small bowel varices. The
non-vascular comprised erythemata, edema, and superficial erosions. The total
number of vascular (p 0.001) and non-vascular lesions (p 0.004) detected by
blue mode was significantly higher than those detected by normal mode (Table).
Moreover, blue mode viewing offered better visualization of the both types of
lesions than normal mode.Conclusions: Blue mode is a good new method,
which has better ability to detect and visualize both vascular and non-vascular
lesions of small bowel than normal mode. As a result, we suggested that blue
mode viewing might reduce the miss rate of capsule endoscopy to a reasonable
degree.
