Answer

Push enteroscopy in some studies has been shown to have a higher diagnostic yield than standard esophagogastroduodenoscopy (EGD). Essentially, this modality uses a long endoscope that is placed through the mouth into the jejunum and can reach about 160 cm beyond the ligament of Treitz.

In one study, push enteroscopy identified a large number of mucosal lesions that could not be identified by a standard endoscope. [9]

Double-balloon enteroscopy is another technology that has shown high therapeutic and diagnostic yield. This modality employs a high-resolution video endoscope with latex balloons attached at the tip, with an overtube that can be inflated and deflated. It can be inserted either orally or anally.

Wireless capsule endoscopy is under investigation for children, although it can be used only diagnostically, not therapeutically.
