1 doctor agrees

In brief: Depends

If the test is done with sedation (typically not necessary) then there are risks of sedation.
Otherwise typical risks of this procedure can include pain or cramps, bleeding (especially if there will be biopsies), infection, missing a lesion or a perforation (hole in the intestine). That being said, these risks are very rare.

In brief: Perforation

There are no common complications to flex sig.
It is generally very safe. The two main risks is a missed lesion (15% rate) and a peroration (<1% rate).
