Double-balloon enteroscopy (push-and-pull enteroscopy) of the small bowel: feasibility and diagnostic and therapeutic yield in patients with suspected small bowel disease

Double-balloon enteroscopy (push-and-pull enteroscopy) is safe and easily conducted. Visualization and tissue sampling are possible in the entire small bowel by using the oral and anal approaches, and treatment is possible in the same way as in standard endoscopy, avoiding open surgery. If further prospective studies confirm its value, double-balloon enteroscopy (push-and-pull enteroscopy) may become a standard method of diagnostic and therapeutic endoscopy in the small bowel.
