Abstract: Background:Capsule endoscopy( CE)has been widely used for the diagnosis of small intestinal diseases. How to enhance the complete examination rate( CER)has attracted more and more attention in recent years. Aims:To investigate the effect of different intervention on gastric transit time( GTT)and small bowel transit time( SBTT)in CE. Methods:Ninety patients undergoing CE from January 2012 to May 2013 at Changhai Hospital were enrolled and randomly divided into control group,right lateral position group and motion group. The patients in control group were allowed to keep quiet, patients in right lateral position group were asked to lie on their right side,and patients in motion group were asked to take rapid pace walking after swallowing the capsule until the capsule passing pylorus. GTT,SBTT,CER and disease diagnosis rate among the three groups were compared. Results:Compared with control group,GTT was significantly decreased in right lateral position group(P﹤0. 05),however,no significant difference in SBTT was found between right lateral position group and control group(P ﹥0. 05). GTT and SBTT were both significantly decreased in motion group than in control group(P﹤0. 05). No significant differences in CER and disease diagnosis rate were found among the three groups(P﹥0. 05). Conclusions:Right lateral position can shorten GTT,rapid pace walking can shorten GTT and SBTT,and both these two intervention have substantial clinical values in CE.
