The video capsule endoscopy is a relatively new procedure, which enables doctors to investigate the small bowel.  The examination is used to detect gastrointestinal bleeding, diagnose Crohn’s and coeliac disease and evaluate prolonged cases of diarrhea.  It is also possible to use it to screen for polyps and detect ulcers.  Capsule endoscope uses a tiny wireless camera, which is swallowed by the patient.  As the capsule moves through the patient’s digestive tract, it takes thousands of pictures which are transmitted to a recording device that is worn on a belt around the patient’s waist.  The capsule is passed naturally in the stool.
