胶囊内镜对小肠肿瘤的诊断价值

目的：评价胶囊内镜对小肠肿瘤的诊断价值，了解小肠肿瘤患者进行胶囊内镜检查的风险。方法：对2002年4月至2003年1月期间进行的53例胶囊内镜检查检出的小肠肿瘤的临床资料进行回顾性分析，并与小肠X线检查的检出情况进行对比。结果：53例小肠胶囊内镜检查共检出小肠肿瘤9例，检出率为16．98％。无症状者3例，无症状人群中小肠肿瘤的检出率为11．11％(3／27)；有症状者6例，症状主要包括：便血、腹痛、腹泻，病程平均为3．83年(1～10年)。胶囊内镜检出的小肠肿瘤包括癌1例、淋巴瘤1例、平滑肌瘤2例、息肉2例、脂肪瘤1例、小肠粘膜下肿物2例(性质未明)。6例经胶囊内镜证实有小肠肿瘤的患者小肠气钡造影只检出1例，胶囊内镜对小肠肿瘤的检出率高于小肠气钡造影。结论：胶囊内镜对小肠肿瘤具有较高的检出能力，为降低胶囊内镜检查的风险，在胶囊内镜检查前，对疑有小肠肿瘤致肠腔狭窄者应行钡餐检查。

Initial experience of capsule endoscopy for evaluating small intestinal neoplasm

Objective: To assess the value of capsule endoscopy in diagnosis of small intestinal neoplasm, and to determine the risk of capsule endoscopy in the patients with small intestinal neoplasm. Methods: We analyzed the outcomes of 53 patients who accepted capsule endoscopy from July 2002 to January 2003 and compared the fields of capsule endoscopy with enteroclysis. Results:9 patients who suffered with small intestinal neoplasm were involved in this study; the detected rate was 16.98%. 3 patients had no symptom, and the detected rate in no symptom people was 11. 11% (3/27). 6 patients had varied symptoms, including; hematochezia, abdominal pain, diarrhea. The mean duration of symptoms was 3. 83 years (1 - 10y). The fields of small intestinal neoplasm detected by capsule endoscopy were carcinoma, lymphoma, leiomyoma, polyp, lipoma, and submucosal mass lesion. 6 patients performed enteroclysis, only one patient was identified with it. Capsule endoscopy was better than enteroclysis in diagnosis of small bowel neoplasm. Conclusion: Capsule endoscopy is a safe and well-tolerated modality for diagnosis of small bowel neoplasm. To reduce the risk that induced ileus by capsule endoscopy, performing enteroclysis is the best resolvent before capsule endoscopy.
