胶囊内镜和双气囊内镜对小肠克罗恩病诊断价值的比较

克罗恩病（CD）是一种原因未明的慢性炎性肉芽肿性病变,可侵及全消化道各部位,约70％的病变累及小肠,诊断需联合其临床表现、内镜检查、组织病理学、影像学、实验室检生化查等。新型检查技术如胶囊内镜和双气囊内镜对评估小肠疾病具有重要作用。本文就胶囊内镜和双气囊内镜在小肠CD中的诊断率作一综述,以进一步明确两者的诊断价值。     

胶囊内镜在克罗恩病中的应用价值

克罗恩病是一种慢性炎性肉芽肿性疾病．可累及胃肠道各部位，其中小肠约占30％～40％。其发病率与地理环境、种族等因素有关。北欧及北美洲发病率较高，南欧、亚洲及一些发展中国家较低，但近年在全球范围及在我国均有呈上升的发展趋势。目前对克罗恩病的诊断主要依据临床表现(腹痛、腹泻、发热、贫血、血沉增快等)、影像学检查和内镜检查中的典型改变。

Clinical outcome of patients examined by capsule endoscopy for suspected small bowel Crohn''s disease

BACKGROUND: Capsule endoscopy has a greater diagnostic yield than radiology for detecting subtle inflammatory changes of the small bowel mucosa, but the clinical significance of these abnormalities is still uncertain because of the lack of long-term follow-ups. AIM AND METHODS: To verify the accuracy of capsule endoscopy in a cohort of patients with suspected Crohn's disease of the small bowel, taking as 'gold standard' the final diagnosis made after a long follow-up. From April 2002 to March 2005, we enrolled and examined by capsule endoscopy 27 consecutive patients with abdominal pain and diarrhea lasting more than 3 months and at least one of the following: anaemia, weight loss, fever, extra-intestinal manifestation(s) of inflammatory bowel disease. All patients already had an unremarkable pan-endoscopy, serology for celiac disease and intestinal radiology inconclusive for small bowel abnormality. On the basis of capsule endoscopy findings, patients were distributed in three groups; Group A had severe stricturing lesions requiring surgery; Group B, moderate inflammatory lesions further investigated invasively; Group C, minimal inflammatory changes or normal findings, clinically observed every 3 months (median 21 months, range 15-29). RESULTS: Small bowel inflammatory lesions were found in 16 of the 27 patients (diagnostic yield 59%). Three had surgery (Group A) and Crohn's disease was confirmed in two; the remainder had ileal adenocarcinoma in a pathological context of chronic inflammation. Crohn's disease was histologically confirmed in four of the five patients in Group B. Group C comprised 19 patients; Crohn's disease was confirmed in seven out of eight with positive capsule endoscopy, while only one of the patients with normal findings later developed overt ileal Crohn's disease. Sensitivity, specificity, positive and negative likelihood ratio were, respectively, 93%, 84%, 5.8 and 0.08. Assuming a 50% pre-test probability of disease, capsule endoscopy gave a post-test probability of 85%. CONCLUSIONS: In our selected cohort, capsule endoscopy was highly sensitive in detecting small bowel inflammatory changes, enhancing by nearly 35% the pre-test probability of structural small bowel disease. Focal erythema and luminal debris may limit the specificity of capsule endoscopy.     

胶囊内镜对消化道疾病的诊断价值

Expanding role of capsule endoscopy in inflammatory bowel disease

Capsule endoscopy has been shown to detect small bowel inflammatory changes better than any other imaging modality. Selection criteria have been optimized to increase the yield of capsule endoscopy in patients suspected to have Crohn＇s disease. Capsule endoscopy allows for earlier diagnosis of Crohn＇s disease of the small bowel and improved diagnosis of colitis in patients where it is unclear if they suffer from Crohn＇s or ulcerative colitis. A test capsule is available to assess for small bowel strictures and thus avoid capsule retention. A common language has been developed and a new scoring index will be added to capsule software. It is envisioned that the manner in which we treat Crohn＇s disease in the future will change, based on earlier diagnosis and treatment aimed at mucosal healing rather than symptom improvement.     

Prospective postsurgical capsule endoscopy in patients with Crohn's disease

AIM: To clarify the usefulness of postsurgical capsule endoscopy(CE) in the diagnosis of recurrent small bowel lesions of Crohn's disease(CD). METHODS: This prospective study included 19 patients who underwent ileocolectomy or partial ileal resection for CD. CE was performed 2-3 wk after surgery to check for the presence/absence and severity of lesions remaining in the small bowel, and for any recurrence at the anastomosed area. CE was repeated 6-8 mo after surgery and the findings were compared with those obtained shortly after surgery. The Lewis score (LS) was used to evaluate any inflammatory changes of the small bowel. RESULTS: One patient was excluded from analysis because of insufficient endoscopy data at the initial CE. The total LS shortly after surgery was 428.3 on average(median, 174; range, 8-4264), and was ≥ 135(active stage) in 78%(14 of 18) of the patients. When the remaining unresected small bowel was divided into 3 equal portions according to the transition time(proximal, middle, and distal tertiles), the mean LS was 286.6, 83.0, and 146.7, respectively, without any significant difference. Ulcerous lesions in the anastomosed area were observed in 83% of all patients. In 38% of the 13 patients who could undergo CE again after 6-8 mo, the total LS was higher by ≥ 100 than that recorded shortly after surgery, thus indicating a diagnosis of endoscopic progressive recurrence. CONCLUSION: Our pilot study suggests that CE can be used to objectively evaluate the postoperative recurrence of small bowel lesions after surgery for CD.

Inter-observer agreement for detection of small bowel Crohn's disease with capsule endoscopy

Abstract

Objective. Compared to other modalities, capsule endoscopy (CE) has a high diagnostic yield for diagnosing small bowel Crohn's disease (CD). The aim of this study was to determine the inter-observer agreement for detection of small bowel CD with predefined diagnostic criteria. Material and methods. Thirty patients with suspected or known CD were included in the study. Observers were blind to patient histories, the results of ileo-colonoscopies, and small bowel examinations. More than three ulcerations (aphthous lesions or ulcers) or the presence of stenosis caused by inflammation or fibrosis was diagnostic of small bowel CD. Three observers with experience in gastrointestinal endoscopy and CE participated in the study. Results. The presence or absence of small bowel CD was determined with complete agreement in 23 patients, nine patients with and 14 without small bowel CD. The inter-observer agreement was substantial for the diagnosis (κ = 0.68) and moderate for the localization of CD (κ = 0.44). Aphthous lesions were detected with only fair agreement (κ = 0.38). The time intervals to passage of the pylorus and ileo-caecal valve were detected with excellent intra-class correlation. Conclusions. CE is performed with substantial inter-observer agreement for detection of small bowel CD. In the majority of patients, the presence or absence of small bowel CD is unequivocal. However, in patients with few or minor lesions, the diagnosis is observer dependent.     

Capsule endoscopy in suspected small bowel Crohn's disease: Economic impact of disease diagnosis and treatment

AIM: To model clinical and economic benefits of capsule endoscopy (CE) compared to ileo-colonoscopy and small bowel follow-through (SBFT) for evaluation of suspected Crohn's disease (CD).METHODS: Using decision analytic modeling, total and yearly costs of diagnostic work-up for suspected CD were calculated, including procedure-related adverse events,hospitalizations, office visits, and medications. The model compared CE to SBFT following ileo-colonoscopy and secondarily compared CE to SBFT for initial evaluation.RESULTS: Aggregate charges for newly diagnosed,medically managed patients are approximately $8295.Patients requiring aggressive medical management costs are $29 508; requiring hospitalization, $49 074.At sensitivity > 98.7% and specificity of > 86.4%, CE is less costly than SBFT.CONCLUSION: Costs of CE for diagnostic evaluation of suspected CD is comparable to SBFT and may be used immediately following ileo-colonoscopy.
