Abstract
Capsule endoscopy is an effective tool for evaluating small bowel diseases. Capsule retention is a complication of capsule endoscopy, but capsule disruption after retention has not been thoroughly studied. Only a few cases of capsule disruption have been reported. We report a case of capsule disruption after prolonged retention. A 73-year-old woman underwent capsule endoscopy for the evaluation of anemia. One week later, capsule retention was observed on radiography. Capsule removal was advised, but she refused because she did not have any symptoms. After 20 months, computed tomography revealed disrupted capsule fragments. Capsule removal was strongly recommended, and the patient agreed. All disrupted capsule fragments were removed using double-balloon endoscopy without complications. Intestinal perforation had been prevented by removing the disrupted capsule before the battery fluid leaked into the intestinal tract. Capsule retention, documented by imaging, should be addressed by removing the retained capsule immediately before capsule disruption occurs.
