不明原因消化道出血患者胶囊内镜检查的时机选择

目的：探讨不明原因消化道出血（OGIB）患者行胶囊内镜检查的最佳时机。方法回顾性分析重庆医科大学附属第二医院和重庆市急救中心2013年1月至2014年12月接受胶囊内镜检查的 OGIB 患者的临床资料，按检查时机的不同分为急诊组和非急诊组，整理两组患者的临床特征、胶囊内镜检查结果、并发症、住院时间及住院费用，并进行统计学分析及比较。结果76例 OGIB 患者接受胶囊内镜检查，发现病变48例，病变总检出率为63．15％。急诊组病变检出率为73．68％（28／38），明显高于非急诊组的病变检出率52．63％（20／38），差异有统计学意义（P ＜0．05）。结论对于 OGIB 患者，急诊胶囊内镜病变检出率更高，条件允许时，对 OGIB 患者应尽早行胶囊内镜检查。

The optimal time of capsule endoscopy for patients with obscure gastrointestinal bleeding

Objective To investigate the optimal time for capsule endoscopy in patients with obscure gastrointestinal bleeding (OGIB) .Methods Data of 76 patients with OGIB underwent capsule endoscopy from January 2013 to December 2014 were retro‐spectively analyzed .They were classified into two groups :emergency capsule endoscopy and non‐emergency capsule endoscopy .The demographic and clinical features and outcomes of capsule endoscopy ,complications and the times of hospital stays and hospitaliza‐tion expenses were compared .Results The overall diagnostic yield of capsule endoscopy was 48 lesions(63 .15% ) .The overall di‐agnostic yield of emergency capsule endoscopy group was 73 .68% (28/38) ,which was significantly higher than that in non‐emer‐gency capsule endoscopy group(52 .63% ,20/38) ,with statistical difference (P< 0 .05) .Conclusion Emergency capsule endoscopy have a higher rate of detection ,patients with OGIB should receive capsule endoscopy as soon as possible .
