Does inserting an endoscope into the anus while fasting invalidate the fast and require a make-up day, knowing that the fasting person completed their fast?

If anal treatment can be delayed until after breaking the fast, then it should be delayed, because, in the view of some jurists, it is considered like an enema that breaks the fast, whether it involves a liquid or a solid. However, if delaying it would result in illness, increased illness, or delayed recovery, then treatment is permissible, with the obligation to make up the fast later. This is based on the opinion that an enema definitively breaks the fast.
