double-balloon enteroscopy (push & pull enteroscopy)
Procedure:
- balloons are attached to the distal ends of an enteroscope & a transparent tube that slides over it
- the balloons are inflated to contact the small intestine & pull it over the enteroscope, allowing visualization of long portions of the small intestine
- the enteroscope may be inserted orally to visualize proximal small intestine or rectally to visualize distal small intestine
Complications:
- procedure-related pancreatitis
