Small bowel motility remains inadequately understood because of the complex and various functions as well as its anatomical position. The aimed of the study was to investigate the small bowel transit time (SBTT) of capsule endoscopy (CE) and to analyze the clinical factors affecting SBTT.
SBTT was analyzed in patients who underwent small bowel CE. Factors contributing to SBTT and CE retention were investigated.
Among 397 patients enrolled in this study, 336 (84.6%) completed CE. The mean SBTT (± standard deviation) was 282.1±132.2 min. According to the univariate and multivariate analyses, aging and small bowel stenosis extended SBTT. In 38 patients who underwent multiple CE studies, considerable variation in SBTT were observed [mean of standard deviations (SDs) =97.97 min, SD of the SDs =81.99 min]. CE retention was observed in 61 patients (13.3%), and it was statistically associated to small bowel lesion.
Aging and small bowel stenosis were associated with longer SBTT. Furthermore, SBTT analyzed by CE should be interpreted carefully considering the intra-individual differences in SBTT.
由于小肠功能复杂多样及其解剖位置特殊，对小肠动力的了解仍不充分。本研究旨在探讨胶囊内镜（CE）的小肠转运时间（SBTT），并分析影响SBTT的临床因素。
对接受小肠CE检查的患者的SBTT进行分析。研究了影响SBTT和CE滞留的因素。
本研究纳入的397例患者中，336例（84.6%）完成了CE检查。平均SBTT（±标准差）为282.1±132.2分钟。根据单因素和多因素分析，年龄增长和小肠狭窄会延长SBTT。在38例接受多次CE检查的患者中，观察到SBTT有相当大的差异[标准差（SD）的均值=97.97分钟，SD的标准差=81.99分钟]。61例患者（13.3%）出现CE滞留，且与小肠病变存在统计学关联。
年龄增长和小肠狭窄与较长的SBTT相关。此外，考虑到SBTT的个体差异，对CE分析得出的SBTT应谨慎解读。
