EGJ: esophagogastric junction; FLIP: functional lumen imaging probe; GERD: gastroesophageal reflux disease.
* A complex stricture has any of the following features:¶ If manometric findings are suspicious for external compression of the esophagus, perform barium esophagram if not done previously.
Δ An example of inconclusive manometric findings may be EGJ outflow obstruction in the absence of other supporting data (eg, imaging or FLIP).
◊ Some patients with inconclusive manometric findings may evolve to a well-defined diagnosis over time. Thus, observation with symptom monitoring may be an option for such patients.
