In some fictional works, enema as punishment might be part of the backstory of a character who has endured abuse. This helps to explain their psychological state and the trauma they carry. It's a rather extreme way to depict the effects of abuse on a character, but it can be very effective in creating a complex and sympathetic character.
One example could be in some historical fiction where a strict nurse in an old - fashioned orphanage might be wrongly depicted as using enema as a form of punishment. However, this is a rather cruel and unethical concept. In modern fiction, such a plot is more likely to be used to show the harshness of a particular era or the abuse of power.

Moreover, they may not be suitable for public consumption or go against moral and social norms in many cultures.
Medical textbooks are a great source. For example, books on gastroenterology or general medicine often cover the topic of enemas from a medical perspective, explaining how they are used for medical treatment, diagnosis, or preparation for certain procedures.
