胶囊内镜对慢性腹痛的诊断分析

Diagnostic analysis of capsule endoscopy in chronic abdominal pain

目的分析胶囊内镜在慢性腹痛中的诊断价值。方法 2008年9月-2009年7月慢性腹痛25例、无消化道症状体检20例进行胶囊内镜检查,对诊断结果进行相关统计学分析。结果胶囊内镜均顺利完成检查,全部胶囊在检查结束后排出体外。检查过程中患者无任何不适。慢性腹痛患者中,小肠溃疡3例(12%),小肠息肉3例(12%),十二指肠扭转1例(4%),空肠静脉瘤1例(4%),空肠蛔虫病1例(4%),回肠黏膜糜烂1例(4%)。无消化道症状的体检者中,小肠息肉2例(10%),回肠黏膜糜烂1例(5%)。小肠疾病在慢性腹痛患者中检出率40%,明显高于无消化道症状的体检者(15%),两者比较有统计学意义(P<0.01)。两组的胃排空时间分别为(40.99±31.38)min和(37.90±24.89)min,到达回盲部时间分别为(220.89±91.64)min和(225.68±80.59)min,两组比较无统计学意义(P>0.05)。结论胶囊内镜在慢性腹痛的诊断中有良好价值,临床安全性好。

Objective The aim of the study is to evaluate value and safety of capsule endoscopy in diagnosing chronic abdominal pain. Methods From Sep. 2008 to July 2009,45 capsule endoscopy procedures were performed in 25 patients with chronic abdominal pain and 20 Asymptomatic controls.Diagnoses by capsule endoscopy were recorded and compared. Results Capsule endoscopies were completed successfully in 45 patients.All of the capsules eventually passed out spontaneously after procedures.All the patients did not complain of any uncomfortable feeling.The finding in chronic abdominal pain group included 3 cases of small intestinal ulcers（12%）,2 cases of small intestinal polyp（8%）,1 case of volvulus of duodenum（4%）,1 case of jejunal phlebangioma（4%）,1 case of jejunal ascarids（4%）,1 cases of ileum erosion（4%）.The findings in asymptomatic control group included 2 cases of small intestinal polyp（10%）,1 case of ileum erosion（5%）.Comparing the 2 groups,prevalence in chronic abdominal pain group was significantly higher than that in asympotomatic control（P0.01）.The capsules were stayed in stomach in（40.99±31.38） min and（37.90±24.89） min,reached in ileum bottom in （220.89±91.64）min and （225.68±80.59） min,no significant difference was found between 2 groups（P0.05）. Conclusion Capsule endoscopy is a safe procedure and valuable tool in diagnosing chronic abdominal pain.
