A 71-year-old woman presented with recurrent abdominal pain. She was diagnosed with Crohn’s disease with ileum stenosis. She underwent endoscopic balloon dilation. At 76 years old, she again presented with lower abdominal pain and diarrhea. She underwent bowel patency testing using a patency capsule (PC) . PC was not excreted within 33 hours, and radiography localized it in the terminal ileum. After 4 days, she again experienced abdominal pain and anorexia. Radiography could not detect the PC, so that it appeared to have dissolved. Symptoms lasted for 7 days, and she underwent colonoscopy. Endoscope 9.2mm in diameter easily passed through the stricture of the ileum, but film that had coated the PC after it dissolved remained at the oral side of stricture. After the film’s removal endoscopically, symptoms resolved. PC may be caught in a small bowel stricture, so attention is required when a PC was not excreted.
