Abstract
A 77-year-old man with a history of non-steroidal anti-inflammatory drugs (NSAID) use was admitted to our hospital due to
anemia and hypoalbuminemia. Radioisotope scintigraphy indicated protein loss from the small intestine. The patient underwent
capsule endoscopy, which was later found to be retained in the ileum. Double-balloon endoscopy showed multiple strictures
with ulcers in the small intestine. The capsule was found in proximal to one of the stenosis, and was removed by doubleballoon
enteroscopy. Based on endoscopic findings, NSAID-induced enteritis was diagnosed. Although anemia and
hypoalbuminemia improved after discontinuing NSAID, the patient developed ileus and underwent partial resection of the ileum.
Multiple diaphragm-like strictures were present in the resected intestine. The current case highlights the importance of
screening for intestinal strictures when NSAID ulcer is suspected.
