Unreal - no evidence it makes any difference! I had mine removed after peritonitis aged 7. I suffered from constipation since, have very poor digestion, IBS, and pick up all manner of stomach bugs very easily when travelling. I had a full gut analysis from stool sample a few months ago and it revealed of the three basic strains of intestinal flora, I had 50% needed of one, 30% of another and ZERO  of the third. So no wonder my gut was permanently distended. I was not digesting my food but fermenting it. I now have to take very expensive high potency probiotics and be very careful with my diet. It is a total pain. I'd like to see more research on the appendix - why do they get inflamed in the first place? If this was understood, perhaps fewer people would need to have them removed.
