Outcome Measures

Primary Outcomes (1)

  • the quality of visualization of the small bowel

    The image quality was evaluated only in cases in which the capsule reached the cecum within the examination period. All CE images will be assessed at low speed (10 frames/s) under the AutoView mode of the RAPID workstation (Given Imaging). The intestinal mucosa is defined as clean if, less than 25% of the mucosal surface was covered by dark liquid, bubbles or debris. Using a timer, the investigators record the exact time period during which the small intestinal mucosa was clean. The definition of "excellent" is at least 90% of the overall small bowel mucosa is clean (the sum of "clean" time /total small bowel transit time\>90%). And the definition of "good" is at least 80% of the overall small bowel mucosa is clean. We considered that "excellent" or "good" preparation is adequate to make an accurate diagnosis.
