Wireless capsule endoscopy and its role in gastroenterology: our results and a review of the literature

INTRODUCTION: Since its recent introduction, capsule endoscopy has revolutionized the diagnostics of diseases of the small bowel. The number of studies on the use of this method is constantly increasing. Along with this, our knowledge about the usability and diagnostic power of capsule endoscopy is growing and the indications for this technique are getting progressively more accurate. AIMS: To study the usability of capsule endoscopy in suspected Crohn's disease, in gastrointestinal bleeding of small bowel origin, and in undetermined abdominal complains. METHOD: Capsule endoscopy was performed in 20, previously examined, carefully selected patients. RESULTS: Positive findings were recorded in all patients with gastrointestinal bleeding and in 3/4 of patients with suspected Crohn's disease. However, in patients with indeterminate abdominal complains, the capsule endoscopy proved to be inefficient. CONCLUSION: In the study below, based on their own experience, the authors try to provide an overall picture of capsule endoscopy by reviewing contemporary medical literature. The usability of the capsule endoscopy in suspected Crohn's disease and gastrointestinal bleeding of small bowel origin is suggested by the results of the study.
