VCE retention occurs in approximately 2% of patients undergoing evaluation for small-bowel bleeding and is most likely due to small-bowel strictures.

The most common reasons for retention were small-bowel strictures, although etiology was not provided in all studies.

Reasons for retention were provided in 60 (77%) studies. Based on subgroup analysis, subsequent VCE completion rates after performance of a patency capsule or CT enterography in patients with IBD to exclude retentions due to strictures was 2.7% (95% CI, 1.1%-6.4%). We used a random effects model and found that the pooled retention rate was 2.1% for patients with suspected small-bowel bleeding (95% CI, 1.5%-2.8%). We included 25 studies (N = 5876) for patients undergoing VCE for evaluation of potential small-bowel bleeding, 9 studies (N = 968) for patients with suspected inflammatory bowel disease (IBD), 11 studies (N = 558) for patients with established IBD, and 8 studies for patients (N = 111) undergoing VCE for evaluation of abdominal pain and/or diarrhea. We used Comprehensive Meta-Analysis (Version 3.0) to calculate pooled prevalence rates with 95% confidence intervals (CIs) and assessed heterogeneity by using the Cochran Q statistic. We included studies that enrolled at least 10 patients, included VCE retention rates, and separated retention rates by indication. We performed a systematic review of VCE retention rates by using Pubmed and SCOPUS (1995-2015). However, retention of the video capsule endoscope remains a major concern. Therefore, AVGs can be a good alternative for sedentary behaviour and addition to traditional physical activity and sports in children/adolescents.īody composition cardiovascular fitness energy expenditure moderate-to-vigorous physical activity.Video capsule endoscopy (VCE) has become a major diagnostic tool for small-bowel evaluation. AVGs could yield equivalent health benefits to children/adolescents as laboratory-based exercise or field-based physical activity. The comparison between AVGs and field-based physical activity had null to moderate effect sizes. The effect sizes for physiological outcomes were marginal when comparing AVGs with laboratory-based exercises. Compared with sedentary behaviours, AVGs had a large effect on health outcomes. Mean effect size (Hedge's g) and standard deviation were calculated for each comparison.

Effect size for each entry was calculated with the Comprehensive Meta-Analysis software in 2015.

Data were extracted to conduct comparisons for outcome measures in three separate categories: AVGs and sedentary behaviours, AVGs and laboratory-based exercise, and AVGs and field-based physical activity. A total of 512 published studies on AVGs were located, and 35 articles were included based on the following criteria: (i) data-based research articles published in English between 19 (ii) studied some types of AVGs and related outcomes among children/adolescents and (iii) had at least one comparison within each study. This meta-analysis synthesizes current literature concerning the effects of active video games (AVGs) on children/adolescents' health-related outcomes.
