Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to assist you.
If he is having problem swallowing, then he may have to undergo tests like barium swallow and esophageal manometry as his endoscopy
If you mean he is having a feeling of something stuck in the throat even after eating, then it indicates GERD
and he needs to continue treatment of GERD.
I hope that answers your question.
