How many times can an egd with dilation of the pylorus be done?

EGD & Dilation: If the reason it was done was to relieve a stricture, you may have to undergo periodic dilations, depending on how long it takes to "open up" the stricture. As with any invasive procedure, you want to limit the number of times it is performed. Only your gastroenterologist knows your complete medical history well enough to advise you on follow up for your symptoms.

No Clear Limit, But: Each time induces tearing of the pylorus tissue with resulting scar formation & scars shrink. Thus each time tends to get more difficult & induces more scare tissue. Like most medical technology, this is simply a method to treat a symptom & does not deal with or solve underlying issues.
