NSAID's use after surgery

Any information, evidence based practice, about taking NSAID's after (let's assume) a normal healthy adult s/p EGD or colonoscopy with a few random biopsies taken?

Our pre-printed routing discharge form has a fill in the blank check list for the doctor to complete. Of course we're lucky if they maybe check one or two lines. We check the obvious ones.....resume normal diet and activities tomorrow.......call (fill in the phone number) for your follow up appointment etc.

They never fill in the blank about "you have had biopsies taken don't take NSAID's, (we actually list the main ones) for ______ weeks." We always just write "until you see your doctor at the follow up appointment."

What do other GI clinics do? For a few random biopsies do NSAID's need to be avoided?
