Savary-Gilliard bougie esophageal dilator
Reusable semi-rigid tapered dilator passed over a previously placed guidewire, in increasing calibers, to dilate an esophageal stricture.
How it is used
Endoscopic dilation of the anastomotic stricture after surgical repair of esophageal atresia, the most frequent cause of pediatric esophageal stricture.
Clinical tip
A comparative study in 40 children found no significant difference in success between the bougie (87%) and the balloon (67%); both are valid options.
