An Innovative Endoscopic Cap for Dilating Benign Esophageal Strictures in Children

The BougieCap is attached to the tip of the endoscope, offers direct visual and tactile control and the endoscope acts as a carrier of the radial and longitudinal force vectors for the dilation.

"A: In the Savary- Bougie treatment, dilators of different sizes are advanced to dilate the stenosis. The same procedure is then repeated with the next larger dilator, with the position of the dilator being checked radiologically each time.~B: In the case of balloon dilation, a balloon is inserted and inflated at the level of the stenosis. Depending on the age of the child and possibly also the etiology of the stenosis, different balloons sizes are applied, which are then maintained inflated for about one until three minutes and the respective pressure. This procedure could take place under endoscopic or radiological control."
