The capsule emits low-dose X-rays that can penetrate the colon contents and identify polyps without the need for bowel preparation. However, one capsule retention occurred in 46 asymptomatic volunteers in a pilot study and it was retrieved by colonoscopy.

In this investigation, we aimed to evaluate the use of DBE for retrieval of endoscopic capsules and identify …
