Small bowel enteroscopy.
For the examination of the small bowel in patients with suspected small bowel bleeding, endoscopic tools to perform deep enteroscopy have become essential. Double balloon enteroscopy has gained worldwide acceptance as an endoscopic technique that can be used safely and effectively to provide complete examination of the small bowel, offer therapeutic intervention, and favorably affect clinical outcomes. Single balloon enteroscopy seems to have utility similar to that of the double balloon system. Preliminary experience with a novel overtube device using either the single or double balloon enteroscope has suggested that this may be a very viable approach to deep enteroscopy. Collectively, these are remarkable innovations that allow access to portions of the small bowel that were previously only available by intraoperative enteroscopy or laparotomy. On the basis of the available data, each of these procedures seems to have unique merits, is generally safe and well tolerated, and is highly likely to be clinically beneficial.
