Abstract
Background: Capsule endoscopy is a new tool that has been proven efficacy in diagnosing multiple small bowel diseases. The Olympus capsule endoscope (EndoCapsule EC type 1) with technology based on a charge-coupled device (CCD) and enhancement system in order to improve image quality was launched recently. The technology also provides an external control system (real time viewer) that facilitates the online checking of the imaging. Limited data has only been presented in some meetings about efficacy of this new technology. Methods and aim: The aim of this study is to report our experience with Olympus endocapsule technology. Up to date we have performed 61 examinations from December 2004 to November 2006. The included patients did either used preparation prior to the test (4L of PEG or 4L of PEG with metoclopramide or fasting). We have reported common findings, indications, quality of preparation, and complications encountered. Results: Seventy percent of the population was males. The mean age was 66.5. The average duration of VCE examination was 8 hours. Overall quality of images was significantly better in PEG prepared examinations. The most common indication was anaemia (obscure & overt GIB) in 68.8%, and Crohn's disease in 23% of the patients. The commonest findings were small bowel angiodysplasia 40%, small bowel ulcerations 18%, nodular and polypoid lesions 1%, active bleeding 0.7%, villous atrophy 0.5%. VCE was able to reach the colon in 80% and terminal ileum in 95% of the patients. One capsule was entrapped in one crohn's stricture in ileum, and two capsules in oesophageal zenker's diverticula (no serious outcomes were encountered in all patients). Conclusion: Our experience with Olympus endocapsule VCE showed that it is a valuable tool in the diagnosis of small bowel diseases, especially bleeding lesions and Crohn's disease. It is a safe, non-invasive and very well tolerated method if used in accordance with ASGE and ESGE guidelines.
