 Balloon endoscopy which was invented by Yamamoto enables an endoscopic approach for the entire bowel in daily clinics. Besides the double balloon endoscope, a single balloon endoscope in whch a balloon is attached only to the splinting tube, but not to the scope itself is being used. The choice of the insertion route is important. Antegrade insertion is selected for overt bleeding when the location of the bleeding point is not clear. Retrograde insertion is chosen for other cases. Carbon dioxide insufflation is helpful for insertion. Crystal violet marking is useful for measuring the insertion distance. It is also helpful for recording the location of the lesions. Angioectasia is observed in green by narrow band imaging. The water emersion method has a magnifying effect. Future enteroscopes may be developed with better insertion ability, a larger instrumental cannel, and zooming.
