Does using water rectally to treat constipation during the the day in Ramadan necessitate making up the fast (qada') or offering expiation (kaffara), and what is the ruling regarding the past two days in which this act was done out of ignorance?

Scholars have differed on whether this act breaks the fast. The majority opinion is that it does break the fast, as it involves introducing something into the cavity. However, others hold that it does not break the fast, as it is neither eating nor drinking. The more cautious approach for a fasting person is to avoid it, to steer clear of the disagreement. If one does break the fast through this act out of ignorance, then there is no compensatory fast (qada') and no expiation (kaffarah (definition)). If one breaks the fast through it knowingly, then only a compensatory fast is obligatory, without expiation.
