Efficiency of bowel preparation for capsule endoscopy examination: A meta-analysis

Figure 1 Proportion of a “good scoring” in small bowel visualization with (B) and without (A) preparation, a meta-analysis of 5 papers and 237 patients. Data were sufficiently homogenous, and statistically significant difference that favored preparation for good visualization is demonstrated. The statistical significance of results did not differ between fixed and random mode.

Figure 2 Proportion of cecum demonstration with (B) and without (A) preparation, a meta-analysis of 7 papers and 401 patients.

Figure 3 Differences in transit times in patients underwent preparation before the capsule examination and those who underwent the procedure without prior preparation, a meta-analysis of 7 papers and 401 patients. A = difference in gastric transit time, B = difference in small bowel transit time.
