UNLABELLED
Aim. To evaluate capsule endoscopy in terms of incomplete examinations and capsule retentions and to find risk factors for these events. Material and Methods. This retrospective and consecutive study includes data from 2300 capsule enteroscopy examinations, performed at four different hospitals in Stockholm, Sweden from 2003 to 2009. Results. The frequency of incomplete examinations was 20%. Older age, male gender, suspected, and known Crohn's disease were risk factors for an incomplete examination. The PillCam capsule had the highest rate of completed examinations. Capsule retention occurred in 1.3% (n = 31). Risk factors for capsule retention were known Crohn's disease and suspected tumor. Complications of capsule retention were acute obstructive symptoms in six patients and one death related to complications after acute surgical capsule retrieval.
CONCLUSION
Capsule endoscopy is considered a safe procedure, although obstructive symptoms and serious complications due to capsule retention can be found in a large series of patients.
目的
评估胶囊内镜检查中检查不完整和胶囊滞留的情况，并寻找这些事件的风险因素。
材料和方法
本回顾性和连续性研究包括 2003 年至 2009 年在瑞典斯德哥尔摩的四家不同医院进行的 2300 例胶囊内镜检查的数据。
结果
检查不完整的频率为 20%。年龄较大、男性、疑似和已知的克罗恩病是检查不完整的风险因素。PillCam 胶囊的完成检查率最高。胶囊滞留发生率为 1.3%（n=31）。胶囊滞留的风险因素为已知的克罗恩病和疑似肿瘤。胶囊滞留的并发症包括 6 例急性梗阻症状和 1 例与急性手术胶囊取出后并发症相关的死亡。
结论
胶囊内镜检查被认为是一种安全的程序，尽管在一系列大型患者中可能会出现因胶囊滞留导致的阻塞症状和严重并发症。
