Spiral Enteroscopy and Balloon-Guided Enteroscopy

Spiral enteroscopy (SE) uses a unique principle of deep enteroscopy. Rotational movement is translated via a soft spiral attached at the outside of an overtube into longitudinal movement. By clockwise rotation of the spiral, the small intestine is continually pleated over the overtube. The bowel and the adherent mesentery are not torqued by this procedure [1, 2].
