The appendix is a small structure located in the lower right side of the abdomen and connected to the large intestine. Appendicitis refers to inflammation of the appendix and is the most common surgical emergency in children and adults.
Children often start with vague pain around the middle of the abdomen and this progresses to pain in the lower right side. Nausea/vomiting and fever are also common.
Treatment is removal of the appendix with surgery. This is an emergency and must be done early to prevent rupture of the appendix and further complications. Most commonly the appendix is removed with a laparoscopic (key-hole) operation but can also be removed with open surgery.
