What kind of endoscopy was this? An upper gastroscopy or colonoscopy? I don't know a massive amount and also it depends what symptoms you had as the reason for it but biopsies are quite common during them. I had a upper gastroscopy because of nausea and vomiting. They found no signs of acid reflux or anything like that so sometimes they take biopsies to find out if there's something causing your symptoms that cannot be seen e.g. Bacteria, I think biopsies can help to detect coeliac etc as well.
Well this wasn't for endometriosis. I have problems with nausea and vomiting so they wanted to check for reflux but I don't have that and coeliac which I don't think I have but haven't got biopsies back yet. I just think my nausea and vomiting is related to some adhesions I had affecting my bowel.
