I am intriqued by the story of a celiac having 6 endoscopies in one
year.  It seems unlikely that celiac disease alone could necessitate that
# of biopsies.  I presume these were for other reason like to treat a
narrowing. If someone has a endoscopy with adequate biopsies of the small
intestine which identifiy the abnormalities in the intestine, there is little
reason to rebioipsy that person within 6 months unless there is a concern
for some other problem.  It is too early to check for healing to do it
less that 6 months after starting the diet. I have heard of people having
a repeat biopsy after only 6 weeks to check for healing, that is too
short a time. Some patients will not need another biopsy.
The decision to rebiopsy and when is not simple and should be
individualised to the patients situation.
