Introduction: In 2001, the Given Imaging® endoscopic capsule was introduced as a noninvasive method that allows total enteroscopy. Olympus® recently developed a small bowel capsule endoscopy with different characteristics in the optical system, battery charging time, recording and image download times, in addition to a system that monitors real-time location of the capsule. Objective: To report the initial experience with Olympus® Endocapsule in Venezuela. Patients and methods: 24 patients with suspected small bowel pathology were evaluated between July and September 2009 using Olympus® Endocapsule. Demographic data, indication for the procedure, gastric time pass, intestinal transit, findings and complications were recorded. Results: 24 patients: 11 male and 13 female. The main indications were obscure gastrointestinal bleeding (n = 15) and chronic diarrhea (n = 4). The average gastric time was 71.03 + SD minutes and intestinal time was 267.9 + SD minutes. In 1 patient the capsule was placed with the gastroscope and in 3 it did not reach the cecum (12.5%). In 11 cases the study was normal (45.83%). There were positive findings in 13 (54.16%) angiectasias (n=6), celiac disease (n=1), subepithelial ulcerated tumor (n=1), intussusception (n 1), red blood in the ileum (n=1), erosions (n=1), lymphangiectasia (n=2). 84.61% of the findings were related to the indication. There were no complications. Conclusion: The Olympus® Endocapsule is useful for diagnosis of small intestine and has a diagnostic yield similar to that reported in the literature for the Given Imaging videocapsule. The shorter time required for charging the battery, download images and the real time system, makes it an alternative for using in emergency conditions. Comparative prospective studies are needed.
