title: Spiral enteroscopy and push enteroscopy.
abstract: Spiral enteroscopy is a new technique for endoscopic evaluation of the small bowel. Currently, more than 3000 cases have been performed worldwide. The Discovery SB device has been approved by the Food and Drug Administration and has been granted a CE mark. The technique is safe and effective for management and detection of small bowel pathology. Recent studies of spiral enteroscopy have demonstrated diagnostic yield, total time of procedure, and depth of insertion that compare favorably with double and single balloon enteroscopy. The strengths of spiral enteroscopy are rapid advancement in the small bowel and controlled, stable withdrawal that facilitates therapy. Future studies will be needed to compare competing technologies. Push enteroscopy is a readily available, safe and effective technique for detecting and treating proximal gut pathology. If performed without an overtube, complications are rare. Use of a dedicated push enteroscope with an overtube is generally reserved for specific indications in which a moderate increase in depth of insertion into the small bowel is required. When capsule endoscopy and deep small bowel enteroscopy are not available, push enteroscopy is a reasonable option with low risk and moderate yield. Push enteroscopy will remain an important part of the armamentarium of the modern endoscopist.
