| Popis: | BACKGROUND There are no reports to prove the repeatability of gastric transit time (GTT) and small bowel transit time (SBTT) in capsule endoscopy (CE). OBJECTIVE To clarify the repeatability and factors that affect GTT/SBTT in CE. METHODS We analyzed the data of 150 healthy subjects from our previous randomized controlled trial that compared small intestinal injuries between two 14-day treatment groups: 1) celecoxib and 2) loxoprofen + lansoprazole. Correlation of GTT/SBTT with pre- and post-treatment CE was analyzed. In addition, the associations of pre-treatment CE SBTT with physical factors, post-treatment CE SBTT and the presence of small intestinal mucosal injuries were analyzed. RESULTS Analyses of 148 subjects pre-treatment CE and 146 subjects post-treatment CE were performed. There were no significant differences between mean GTT and SBTT before and after treatment. Both GTT (𝜌 = 0.22, p < 0.01) and SBTT (𝜌 = 0.47, p < 0.0001) showed positive correlations between pre- and post-treatment CE. In pre-treatment CE, physical factors and the presence of small intestinal mucosal injury had no associations with SBTT. CONCLUSIONS Moderate correlation in SBTT and slight correlation in GTT were shown on repeated CE. The factors affecting SBTT were not clarified in this analysis. |
