Update in enteroscopy: New devices and new indications.

The present review provides an update of the currently available (proto-) types of device-assisted enteroscopy (DAE). In recent years, newly designed double- and single-balloon enteroscopes have emerged. They aim to improve insertion depth into the small bowel, and they also allow more efficient endoscopic interventions. Nowadays, almost all conventional endoscopic procedures are feasible using DAE, opening the door to new indications. Recently, more data have become available on pediatric DAE, DAE-assisted colonoscopy, and DAE in patients with altered anatomy, including DAE-assisted endoscopic retrograde cholangiopancreatography and direct cholangioscopy. Although new enteroscopes are being developed, few comparative studies are available in order to define which DAE suits best for each indication. It is the duty of the international endoscopy community to set up clinical research projects to provide answers to these open questions.
