Midwest how was the esophageal stricture finally identified? We can see there is also a problem in the esophagus on my husband's x-ray but it looks like a bulging hernia type thing that protrudes with the swallow and effectively blocks the passage, and then goes back flat when the swallowing is terminated. His epiglotis is not closing over his airway properly with the swallow and so of course what ever was being swallowed hits the blockage in the esophagus and comes back up and down into the airway. We see ENT surgeon on Mon. and will see what he thinks when he has seen the swallowing video. We are hoping for a good outcome from all of this as he is cancer free presently. Thanks for your response, very interesting.
