Core Tip
Core tip: This is the first study, to our knowledge, to specifically examine the effect of battery life on capsule endoscopy completion rate (i.e., complete visualization of the entire small bowel). Capsule endoscopies performed using SB2U had longer recording time and a corresponding trend toward higher completion rate than the older-generation SB2. As the two systems are identical in dimensions, there was no difference in the transit times. There was no difference in the rates of positive findings. A randomized controlled trial would be necessary to confirm the diagnostic advantage of longer battery life in capsule endoscopy.
