My son was diagnosed with appendicitis the results of it. He had an abscess on his pelvis blocking his bowel and bladder will he hve any future health?

Abcess appendix. Sorry to hear about your little gut. While his immediate recovery may take a bit longer because of rupture, there is usually not much else long term that could be problematic. Sometimes there is a bit more scar tissue in the area from a ruptured appendix. Which could make child a bit more prone to obstruction down the road, but if good surgical technique and debridement done, unlikely!
