摘      要：AIM:To determine if longer battery life improves capsule endoscopy(CE) completion ***:A retrospective study was performed at a tertiary,university-affiliated hospital in Vancouver,*** who underwent CE with either PillCamTM SB2 or SB2 U between 01/2010 and 12/2013 were considered for ***2 and SB2 U share identical physical dimensions but differ in their battery lives(8 h vs 12 h).Exclusion criteria included history of gastric or small bowel surgery,endoscopic placement of CE,interrupted view of major landmarks due to technical difficulty or significant amount of debris,and repeat CE using same *** demographics,comorbidities,medications,baseline bowel habits,and previous surgeries were *** of major landmarks in CE were recorded,and used to calculate gastric transit time,small bowel transit time,and total recording time.A complete CE study was defined as visualization of *** times and completion rates were ***:Four hundred and eight patients,including 208(51.0%) males,were included for *** mean age was 55.5 ± 19.3 *** most common indication for CE was gastrointestinal bleeding(n =254,62.3%),followed by inflammatory bowel disease(n =86,21.1%).There was no difference in gastric transit times(group difference 0.90,95%CI:0.72-1.13,P =0.352) and small bowel transit times(group difference 1.07,95%CI:0.95-1.19,P =0.261) between SB2 U and SB2,but total recording time was about 14% longer in the SB2 U group(95%CI:10%-18%,P 0.001) and there was a corresponding trend toward higher completion rate(88.2% vs 93.2%,OR =1.78,95%CI 0.88-3.63,P =0.111).There was no statistically significant difference in the rates of positive findings(OR =0.98,95%CI:0.64-1.51,P =0.918).CONCLUSION:Extending the operating time of CE may be a simple method to improve completion rate although it does not affect the rate of positive findings.
