To determine if longer battery life improves capsule endoscopy (CE) completion rates.
A retrospective study was performed at a tertiary, university-affiliated hospital in Vancouver, Canada. Patients who underwent CE with either PillCam™ SB2 or SB2U between 01/2010 and 12/2013 were considered for inclusion. SB2 and SB2U 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 system. Basic demographics, comorbidities, medications, baseline bowel habits, and previous surgeries were reviewed. Timing 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 cecum. Transit times and completion rates were compared.
Four hundred and eight patients, including 208 (51.0%) males, were included for analysis. The mean age was 55.5 ± 19.3 years. The 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 SB2U and SB2, but total recording time was about 14% longer in the SB2U 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).
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.
确定更长的电池续航时间是否能提高胶囊内镜检查（CE）的完成率。
在加拿大温哥华一家大学附属的三级医院进行了一项回顾性研究。纳入2010年1月至2013年12月期间使用PillCam™ SB2或SB2U进行CE检查的患者。SB2和SB2U的物理尺寸相同，但电池续航时间不同（分别为8小时和12小时）。排除标准包括胃或小肠手术史、CE内镜放置史、因技术困难或大量碎片导致主要地标视野中断，以及使用同一系统重复进行CE检查。回顾了基本人口统计学、合并症、药物治疗、基线排便习惯和既往手术情况。记录CE检查中主要地标的时间，并用于计算胃传输时间、小肠传输时间和总记录时间。完整的CE检查定义为观察到盲肠。比较传输时间和完成率。
纳入408例患者进行分析，其中男性208例（51.0%）。平均年龄为55.5±19.3岁。CE检查最常见的适应证是胃肠道出血（n = 254，62.3%），其次是炎症性肠病（n = 86，21.1%）。SB2U组和SB2组之间的胃传输时间（组间差异0.90，95%CI：0.72 - 1.13，P = 0.352）和小肠传输时间（组间差异1.07，95%CI：0.95 - 1.19，P = 0.261）无差异，但SB2U组的总记录时间长约14%（95%CI：10% - 18%，P < 0.001），且完成率有相应升高趋势（88.2%对93.2%，OR = 1.78，95%CI 0.88 - 3.63，P = 0.111）。阳性发现率无统计学显著差异（OR = 0.98，95%CI：0.64 - 1.51，P = 0.918）。
延长CE的操作时间可能是提高完成率的一种简单方法，尽管它不影响阳性发现率。
