title: Retention of the cellophane wall of a patency capsule by intestinal stenosis: a report of three cases.
abstract: Here we report three cases in which the cellophane wall of the PillCam®patency capsule (tag-less PC), lacking a radio frequency identification tag, was retained. Case 1 A 33-year-old man with Crohn's disease (CD) who was administered the tag-less PC, subsequently underwent resection for perforated colon. We recovered the cellophane wall that could perforate the intestine and cause peritonitis. Case 2 A 34-year-old man with a recurring intestinal obstruction of unknown cause was administered the tag-less PC test. Computed tomography (CT) detected the cellophane wall at the oral side of an ileal stenosis. He was subsequently diagnosed with CD. Case 3 A 60-year-old woman with recurrent diarrhea was examined using CT, which revealed a thickened ileal wall. She was administered the tag-less PC test. CT detected the cellophane wall at the oral side of an ileal stenosis. Double-balloon enteroscopy revealed that the stenosis was caused by a malignant lymphoma, and the cellophane wall was simultaneously removed. Although there are numerous studies that report the usefulness and safety of tag-less PCs, few studies mention entrapment of the cellophane wall. Our present report indicated that tag-less PCs may cause such adverse effects and illustrated the usefulness of CT for detecting the trapped cellophane wall.
