HI. Thanks for a good elucidate history.
You have Barrett's with a tortuous esophagus
The tortuosity suggests only one thing . That is there was / is still an obstruction in the lower part of the esophagus leading to back-pressure and dilatation is caused by this.
There can be associated motility disorder
related to the esophagus.
This causes chest pain
. The swallowing difficulty come only if the obstruction is tight enough to hod the food.
Chest pain is caused by this only.
You can consult the Gastroenterologist and He will ask you to undergo further tests . He may go for biopsy
, manual dilation for the stricture if present, and advise you medicines. Barium swallow test has still a place in the diagnosis and management.
