This is an interesting report on important clinical problem:  
 
 
If CE is useful in reducing rebleeding.  
 
 
This sentence must be shortned:  
 
Among 58 patients with positive findings on initial CE, 21 patients (36%) had a rebleeding 
event. The re -bleeding event occurred in 47% (8/17) of patients who had angiodysplasia, 
followed by 40% (4/10) of vascular lesions, 30% (6/20) of small bowel ulcer,  and 30% (3/10) of 
small bowel tumor. To identify the etiologies of recurrent bleeding, EGD, colonoscopy, device -
assisted endoscopy, computer tomography with angiography or repeat CE were performed after 
the re -bleeding events. In the group of positive find ings on the initial CE, re -bleeding occurred in 
21 patients
