The so-called "pre-operative filing agreement" refers to the agreement signed between consumers and hospitals before plastic surgery, indicating the risks of surgery and the existence of other irresistible factors. The consumer signs after confirming that she knows, and there is a third party for filing (here I think it is their website for filing stubs). Escort the operation process and provide legal basis for disputes arising from operation failure.

If the operation fails, this agreement can help both parties to provide reliable evidence and legal basis, so that they will not "speak without evidence"
