Introduction: the capsule endoscopy (CE), from his approval, has become a first line diagnostic procedure for the study of the small bowel disease. The aim of this study is to report our experience since the implantation of this technique in our hospital. Material and methods: retrospective review of the CE undertaken in Department of Endoscopy. There was gathered in every case the age, sex, motive of consultation, previous diagnostic procedures, capsule endoscopy findings and complication of the technique. One took to end a descriptive and analytical analysis. Results: there was achieved a total of 416 explorations in 388 patients. The obscure gastrointestinal bleeding was the most frequent indication (83.30%) followed by suspected Crohn's disease (7.5%). Angiodisplasia was the endoscopic lesion more frequently detected (42.2%), especially, in patients with digestive bleeding of obscure origin (OR 3.13 p < 0.001), followed by the flebectasia (10.6%) and the ulcer suspicious of Crohn’s disease (9.9%). The global diagnostic yield as for the detection of injuries was 77.34% with a case of "not defecation of the capsule' and therefore need of laparotomy. Conclusions: the capsule endoscopy is a technique consolidated and as his potential is known, his indications are extended. The obscure gastrointestinal bleeding is the most frequent indication and the angiodisplasia the most identified injury. Once known his diagnostic yield, larger studies are needed that assess the influence of capsule endoscopy on clinical outcoumes.
