case_images: Abdominal radiographs taken at (a) 31, (b) 56, and (c) 218 hours after ingestion showing the patency capsule to be moving anally, but finally becoming retained in the right iliac fossa (arrowheads).

case_images: The capsule was visible in the left upper abdomen at 31 hours after ingestion by radiography (Figure 1(a)) and had moved to the lower abdomen at 56 hours (Figure 1(b)). Surprisingly, the patency capsule was lodged in the right iliac fossa after 218 hours (Figure 1(c)).

case_images: Colonoscopy carried out at 223 hours (at 9 days) after ingestion of the patency capsule revealed severe stenosis of a postoperative stricture at an anastomotic site of the rectum (Figure 2).

case_images: We conducted endoscopic balloon dilatation of the stenotic lesion using a 12-15 mm balloon via colonoscopy (Figure 3) and could pass the colonoscope through the stenosis.
case_images: The patency capsule was found to be surrounded by colonic feces.

case_images: The patency capsule was found to be covered by feces at the blind-ending colon (Figure 4) but was easily and successfully collected (Figure 5) to reveal that the body and plugs were virtually intact.
case_images: The patency capsule was collected from the colon by colonoscopy.
