Esophageal Bougie
Also called Bougie, Esophageal dilator
- Type
- Specialty
Long, flexible cylinder passed through the mouth into the esophagus and stomach, about 29 1/2 in (75 cm) long. Modern ones are silicone filled with tungsten gel; the Maloney style has a tapered, radiopaque flexible tip and calibration marks, the Hurst style a rounded tip.
Primary uses
What this instrument is on the table to do.
In gastric bypass it calibrates the stomach pouch: after the gastric tube is taken out, the anesthesia provider passes the bougie (18 mm in the cited robotic technique) and the pouch is stapled along it, which helps avoid a pouch that is too tight or too loose. It also dilates esophageal narrowing. In open procedures near the esophagus the dilator set is given to the anesthesia provider.

Sized in French. Teleflex/Pilling Hurst tungsten-filled bougies 20 to 40 Fr; Maloney tapered tungsten-filled bougies in a range of sizes. Calibration sizes for bariatric pouches are chosen by the surgeon (18 mm in the cited guide).
