OMOM胶囊内镜对小肠疾病的诊断价值研究

Diagnostic Value of the OMOM Capsule Endoscope in Small Intestinal Diseases

目的探讨OMOM胶囊内镜对小肠疾病的诊断价值,观察胶囊内镜检查的顺应性和安全性。方法 2007-06～2012-07间,325例经B超、CT、胃镜和肠镜等常规检查不能明确病因的患者(其中不明原因消化道出血175例,慢性腹痛88例,慢性腹胀37例,慢性腹泻25例)接受OMOM胶囊内镜检查,评价其阳性率、确诊率和并发症发生率等。结果 325例患者中有245例发现阳性病灶,总体阳性率75.38%;不明原因消化道出血病因确诊率82.30%(144/175),慢性腹痛的阳性诊断率为67.00%(60/88),慢性腹胀的阳性诊断率为67.60%(25/37),慢性腹泻的阳性诊断率为64.00%(16/25),5例(1.50%)发生胶囊滞留,受检者顺应性、安全性良好。结论胶囊内镜检查操作简单、安全,且无创伤,对小肠疾病具有较高的诊断价值,可作为小肠疾病病因诊断的首选筛查手段。

Objective To study on the efficiency and safety of OMOM capsule endoscope in patients with small intestinal diseases.Methods Among 325 cases with negative findings of other routine diagnostic modalities as B supersonic,CT,gastric endoscopy,and colonic enscopy（175 cases were obscure gastrointinal bleeding,88 were chronic abdominal pain,27 were chronic abdominal distention and 7 were chronic diarrhea）,OMOM capsule endoscope was performed and the findings were analyzed from retrospective analysis from June 2007 to July 2012.Results Lesions were detected in 245 of 325 patientes,and positive rate is 75.38%.In 175 cases with obscure gastrointinal bleeding,144 cases obtained final diagnosis,and the rate was 82.30%.In 88 cases with chronic abdominal pain,60 cases obtained final diagnosis,and the rate was 67.00%.In 37 cases with chronic abdominal distention,25 cases obtained final diagnosis,and the rate was 67.60%.In 25 cases with chronic diarhea,16 cases obtained final diagnosis,and the rate was 64.00%.The capsules were easy to swallow,painless and safe.Capsule retention occurred in 5（1.5%）patients.Conclusion Capsule endoscopy has the advantages of simple operation,higher safety and no injury.In small intestinal diseases,capsule endoscope could provide a high diagnostic yield.It may be used as the first choice of diagnostic screening device in small intestinal diseases.
