Background: The inability to pass endoscopes beyond strictures is a considerable problem in patients with a colonic stricture.
Methods: In patients with bowel obstruction, we have modified the insertion method for double-balloon endoscopy with a long, transnasal decompression tube.
Observations: We have succeeded in reaching the proximal side of the stricture from the oral approach across the entire small bowel in a patient.
Conclusions: This modified double-balloon enteroscopy is useful for patients with bowel obstruction in whom a long decompression tube is already placed.
