影响胶囊内镜诊断不明原因消化道出血因素的分析

目的为提高胶囊内镜诊断不明原因消化道出血的诊断率,探讨影响胶囊内镜诊断不明原因消化道诊断率的因素。方法胶囊内镜检查172例,其中不明原因的消化道出血的患者61例,分为2组,A组为胶囊内镜检查明确出血病变者,B组为无明确出血病变者,根据年龄、性别、病史、病变程度、病变表现、排空时间、肠道清洁、检出率、诊断率等对比分析。结果消化道出血的检出率为88．52％,包括胃炎、肠炎、血管畸形、肠息肉、食管静脉曲张等。出血的诊断率为67．2％,包括小肠糜烂,克罗恩病、糜烂性胃炎、溃疡病、肿瘤等。两组病人年龄、性别比较无明显差异,A组病史活动性出血者多,病史长,合并症多,小肠转运时间较长,肠道清洁好,病变程度重,病变检出率高。结论注意病人的选择、合理的小肠转运时间、肠道清洁好、了解出血原因和排序、提高病变鉴别、图像解读及临床综合判断和随访等,可以提高胶囊内镜检查的诊断率,使不明原因消化道出血病变得到及时明确的处理。

胶囊内镜对不明原因消化道出血诊断价值的评估

背景：对于不明原因消化道出血（OGIB），胶囊内镜是一种有价值的诊断方法。但迄今为止，该技术在OGIB诊断中应用的研究多限于小样本病例。目的：评价胶囊内镜对OGIB的诊断价值，确定其敏感性，特异性，阳性，阴性预测值和总诊断率。方法：2002年5月-2005年1月，对连续选取的91例OGIB患者行胶囊内镜检查94次，对胶囊排出时间，再检查，治疗，再出血，依从性和并发症等情况进行随访观察。结果：胶囊内镜检查的阳性率为74.7%，疑诊率为11.0%，阴性率为14.3%。其诊断OGIB的敏感性，特异性以及阳性，阴性预测值分别为94.6%、88.9%和80.0%，总诊断率为93.8%。检查过程中仅1例（1.1%）患者发生胶囊滞留，后经手术取出并证实为克罗恩病所致的肠腔狭窄。结论：胶囊内镜对于OGIB是一种有效而安全的检查手段，迟早行胶囊内镜检查可使患者早日明确诊断并得到及时治疗，从而改善预后。

Clinical utility, safety and tolerability of capsule endoscopy in urban Southeast Asian population

AIM: Capsule endoscopy has demonstrated its clinical utility in the evaluation of small bowel pathology in several Western studies. In this prospective study, we aimed to determine the clinical utility, safety and tolerability of capsule endoscopy in the evaluation of suspected small bowel disease in an urban Southeast Asian population.METHODS: We used the given (M2A) capsule endoscopy system in 16 consecutive patients with suspected small bowel pathology. In 9 patients the indication was obscure gastrointestinal bleeding, while in 6 patients it was to determine the extent of small bowel involvement in Crohn‘s disease. One patient underwent capsule endoscopy for evaluation of chronic abdominal pain. Patient‘‘s tolerabilityto the procedure was evaluated by standardized questionnaires and all patients were reviewed at one week to ensure that the capsule had been excreted without any adverse events.RESULTS: Abnormal findings were present in 8 patients (50 %). The cause of obscure gastrointestinal bleeding was determined in 5 out of 9 patients. Findings included 2 cases of angiodysplasia, 2 cases of jejunal ulcers and 1 case of both angiodysplasia and jejunal ulcer. One patient had smallbowel erosions and foci of erythema of doubtful significance. Ileal lesions were diagnosed in 2 out of 6 patients with Crohn‘‘s disease. Capsule endoscopy was well tolerated by allpatients. One patient with Crohn‘‘s disease had a complication of capsule retention due to terminal ileum stricture. Thecapsule eventually passed out spontaneously after 1 month. CONCLUSION: Our study, which represented the first Asian series, further confirms the diagnostic utility, safety and tolerability of wireless capsule endoscopy.

Wireless capsule endoscopy for obscure small-bowel disorders: final results of the first pediatric controlled trial.

BACKGROUND AND AIMS: Obscure small-bowel disorders are jejunal and ileal lesions undiagnosed by traditional imaging techniques (endoscopic, radiologic). We evaluated the diagnostic usefulness and safety of capsule endoscopy for obscure small-bowel disorders in children and adolescents. METHODS: Comparative, prospective, self-controlled trials in patients (age, 10-18 y) suspected to have either small-bowel Crohn's disease, polyps, or obscure gastrointestinal (GI) bleeding. Capsule results were compared with the diagnostic imaging studies normally used in this age group. RESULTS: Among 20 patients suspected of Crohn's disease, multiple lesions consistent with this diagnosis were observed by capsule endoscopy in 50%. Small-bowel Crohn's disease was ruled out in 8 patients. Eosinophilic enteropathy was found in 2 others. For polyp detection (n = 6), capsule endoscopy yielded 100% concordance with the control studies when analyzed per patient. However, capsule endoscopy revealed a greater number (50%) of polyps. Among patients with obscure bleeding (n = 4), the capsule examination confirmed a diagnosis of vascular malformations in 3. Capsule endoscopy more accurately identified the precise source of bleeding compared with angiography. All 30 capsule studies were well tolerated, although 1 capsule was retained owing to an inflammatory stenosis. The capsule eventually was expelled after corticosteroid therapy. CONCLUSIONS: Capsule endoscopy correctly diagnosed or excluded a bleeding source, small-bowel polyps, or Crohn's disease of the small bowel in 29 of 30 patients. Capsule endoscopy permits an accurate, noninvasive approach for diagnosing obscure small bowel lesions in children over the age of 10.     

Clinical application of video capsule endoscopy

BACKGROUND: Non-invasive imaging of the complete small bowel has become possible with the recently available video capsule endoscopy technique. The aim of this study was to review and assess the possibilities and limitations of the clinical application of video capsule endoscopy. METHODS: Literature review. RESULTS: Video capsule endoscopy is a new promising technique with good to excellent visualization of the mucosa of the small bowel. It has a high diagnostic yield in patients with occult gastrointestinal blood loss (OGIB) and Crohn disease (CD). Several other indications need further study. Compared to small-bowel X-ray and push enteroscopy, diagnostic yield appears to be superior. Video capsule endoscopy is very well tolerated by patients. Its most important limitation is the impossibility of taking biopsies and therapeutic interventions. CONCLUSION: Video capsule endoscopy is a promising new diagnostic tool for small-bowel disease.
