Abstract
Capsule endoscopy is being increasingly recognized as a gold standard for diagnosing small bowel disease, but along with the increased usage, capsule retention is being reported more frequently. We report a case of capsule endoscopy retention in a diverticulum of the duodenal proximal third portion, which we treated by esophagogastroduodenoscopy. A 69-year-old male visited hospital with hematochezia. He had hypertension and dyslipidemia for several years, and was taking aspirin to prevent heart disease. CT and colonoscopy revealed a diverticulum in the third portion of the duodenum, rectal polyps, and internal hemorrhoids. Capsule endoscopy was performed but capsule impaction occurred. The capsule was later detected by CT in the diverticulum. Endoscopy was performed a day later and the capsule was removed using a net. A small bowel series was conducted after capsule removal, and no stenosis was found. The patient fully recovered and no recurrence of hematochezia was observed at his one month exam. This is the first case in Korea of capsule retention in a duodenal diverticulum, with successful removal by endoscopy.
