On page 152 under section 4 (ESOPHAGEAL WEB), what are you referring to when you say the “jet phenomenon”?
- When barium passes through the poorly canalized esophagus, there is a “jet” of propelled barium distal to the initial point of constriction. When looking at a barium swallow, it’s the thin area of barium seen. When that area is tortuous, it can resemble a TE fistula. When it’s linear, it does not. New description is below
ESOPHAGEAL WEB
An esophageal web can cause reflux-like symptoms, esophageal impaction and chest pain. It results from the failure of the esophagus to re-canalize in utero. The web then acts as an obstruction to the passage of a food bolus. Liquids, however, pass through more easily. Treatment requires dilation of the esophageal web.

PEARL: The “jet phenomenon” refers to the thin area of barium seen when looking at a barium swallow. It starts at initial point of constriction. When that area is tortuous (http://bit.ly/oF2ryU), it can resemble a TE fistula. When it’s linear it does not (http://www.ajronline.org/content/129/4/747.full.pdf – page 1 – see it and move on!).
