Abstract
Although capsule retention is a known complication of small bowel capsule endoscopy, initial studies with colon capsule endoscopy (CCE) have not reported any capsule retention or sticking neither in the small bowel nor in the colon. We report a complication of CCE when the stuck colon capsule was passed through the malignant colon stricture and removed by the aid of a flexible colonoscope. During CCE in a 76-year-old iron deficiency anemia patient the real-time viewing system indicated the colon capsule to be stuck in a malignant ascending colon stricture for more than two hours. With the aim to avoid complete capsule retention, immediate colonoscopy was performed. The stuck capsule was caught by a polypectomy snare, passed through the tumor stricture and finally removed from the large bowel. The current case describes the usefulness of the real-time viewing system. Similar situations may occur during the forthcoming spread of CCE and the present case is an example of how to manage the potentially risky stuck colon capsule condition.
