Gastric retention and delayed gastric emptying of the video capsule are major limitations. We retrospectively studied gastric transit time, gastric retention, and completeness of capsule endoscopy (CE) in relation to the conditions in which it was performed.
From May 2002 to September 2004, CE was performed in 190 patients (92 men; mean age, 58.4 years, range 16-91 years). Patients were stratified according to the way CE was performed (hospital day setting, outpatient, or ongoing hospitalization), and the recordings were analyzed to measure gastric retention, gastric transit time, and the completeness of the examinations.
CE examination was performed in a hospital day setting in 100 patients, in an outpatient setting in 61, and during hospitalization in 29. Gastric retention of the capsule occurred in 8 of 190 patients (4.2%) (5 women, 3 men; mean age, 37.9 years). Gastric retention occurred during hospitalization in 7/29 (24.1%) and in hospital day setting in one of 100. Ongoing hospitalization was statistically associated with an increased risk of gastric capsule retention (p < 0.0001). The cecum was reached in 165/190 (87%), and ongoing hospitalization was associated with a lower rate of complete examinations (p < 0.001). Small-bowel transit time was similar, regardless of the circumstances of CE performance.
Ongoing hospitalization is a major cause of gastric retention and incomplete examination by CE. Therefore, CE performance during ongoing hospitalization may require the use of a prokinetic agent.
视频胶囊的胃潴留和胃排空延迟是主要局限性。我们回顾性研究了胃传输时间、胃潴留以及胶囊内镜检查（CE）的完整性与检查实施条件之间的关系。
2002年5月至2004年9月，对190例患者（92例男性；平均年龄58.4岁，范围16 - 91岁）进行了CE检查。根据CE的实施方式（住院日检查、门诊检查或持续住院期间检查）对患者进行分层，并分析记录以测量胃潴留、胃传输时间和检查的完整性。
100例患者在住院日进行了CE检查，61例在门诊进行，29例在住院期间进行。190例患者中有8例（4.2%）出现胶囊胃潴留（5例女性，3例男性；平均年龄37.9岁）。7/29例（24.1%）在住院期间出现胃潴留，100例中的1例在住院日出现胃潴留。持续住院与胶囊胃潴留风险增加在统计学上相关（p < 0.0001）。165/190例（87%）到达了盲肠，持续住院与完整检查率较低相关（p < 0.001）。无论CE检查的情况如何，小肠传输时间相似。
持续住院是CE检查出现胃潴留和检查不完整的主要原因。因此，在持续住院期间进行CE检查可能需要使用促动力剂。
