[Utility of capsule endoscopy in pediatric gastroenterology].

Wireless endoscopy is a new noninvasive diagnostic method that is able to visualize small bowel lesions. The instrument is small and carries a battery and microcamera that takes two photographs per second. It is indicated in cases of bleeding of unknown origin and for the diagnosis of inflammatory bowel disease, among other disorders. To date, it has mainly been used in adults. We believe that this instrument could play an important role in the pediatric age group since it is noninvasive and can be used to diagnose small bowel lesions, thus avoiding unnecessary diagnostic tests. We report the case of a girl with suspicion of Crohn's disease that was unconfirmed by conventional endoscopic techniques. The capsule showed small bowel lesions compatible with Crohn's disease. Corticosteroid treatment was initiated and the patient is now in clinical remission.
