胶囊内镜诊断小肠克罗恩病的应用研究

目的 探讨胶囊内镜在小肠克罗恩病诊断中的应用价值。方法 对20例其它检查正常但临床症状疑似小肠克罗恩病的患者进行胶囊内镜检查，这些患者伴有不同程度腹痛、消瘦、大便隐血阳性、缺铁性贫血、腹泻或发热等症状体征，平均持续6．5年。结果20例患者中共发现克罗恩病13例，胶囊内镜下表现包括黏膜糜烂(2例)、口疮样溃疡(5例)、肉芽肿性结节样病变(1例)，大溃疡(2例)和溃疡伴肠腔不完全狭窄(3例)。结论 胶囊内镜对经传统方法未能检出的疑似小肠克罗恩病具有较高的检出率，尤其是对疾病早期和对轻型患者的诊断具有明显优越性。

Capsule endoscopy in diagnosing small bowel Crohn's disease

Objective To evaluate the effectiveness of wireless capsule endoscopies in patients with suspected CD of the small bowel.Methods From May 2002 through April 2003, we prospectively examined 20 suspected CD patients by capsule endoscopies with normal results in other conventional examinations. It includes the presence of the following symptoms and signs: abdominal pain, weight loss, positive fecal occult blood test, iron deficiency anemia, diarrhea and fever. Mean duration of symptoms before diagnosis was 6 5 years.Results Of the 20 participants, 13 (65%) were diagnosed as having CD of the small bowel according to the findings of the M2A Given Capsule. Among the findings detected by the capsule were mucosal erosions (2 patients), aphthae (5 patients), granulomatous nodularity (1 patient), large ulcers (2 patients), and ulceration with incomplete obstruction (3 patients). All of the 13 patients who received medications showed good clinical improvement.Conclusion Wireless capsule endoscopies were the effective device for diagnosing patients with suspected CD, undetected by conventional diagnostic measures.It may be more likely to detect early lesions in the small bowel of patients with CD.
