title: Capsule endoscopy: a cause of late small bowel obstruction and perforation.
abstract: Case Report. A 71-year-old man was admitted to the department of gastroenterology with diffuse abdominal pain. Through the previous 12 months, the patient had experienced episodes of vomiting and watery diarrhea of increasing intensity as well as weight loss. The patient was evaluated with ultrasound, MRI, and subsequently a capsule endoscopy. Six months later, the patient presented, and an abdominal CT-scan showed mechanical small bowel obstruction with suspicion of metallic foreign body and perforation. Laparotomy showed perforation, stenosis, and foreign body, approximately 5 cm from the ileocecal valve. A right hemicolectomy and distal ileectomy (60 cm) with an ileostomy were performed. On further inspection of resection, a capsule endoscope was found impacted in a stenosis. The ileostomy was later reversed without complications. Conclusion. It is important to be aware of the possibility of capsule retention, especially in patients with known or suspected Crohn's disease, due to the propensity of Crohn's disease to form stenosis of the bowel. In cases where a stenosis is suspected, it is warranted to perform a patency capsule swallow before subjecting the patient to a capsule endoscopy.
