Extraction of entrapped capsules from the small bowel by means of push-and-pull enteroscopy with the double-balloon technique.

The new technique of push-and-pull enteroscopy using the double-balloon technique (double-balloon enteroscopy) makes it possible to remove swallowed foreign bodies causing intestinal obstruction deep in the small bowel without the need for surgical laparotomy. This report describes two cases of enteroscopic removal of entrapped capsules. In one patient with acute recurrent intestinal bleeding and recurrent abdominal pain, Crohn's disease had been suspected on capsule endoscopy. The second patient, with known Crohn's disease, was suffering from abdominal pain and underwent capsule endoscopy for investigation of the small bowel. Prior enteroclysis had not revealed stenoses in either patient. An oral approach was chosen and the capsules were identified approximately 140 cm and 310 cm from the pylorus, respectively, in front of stenoses. The capsule endoscopes were removed successfully in both patients by means of push-and-pull enteroscopy using a new enteroscope device.
