Most children stay in the hospital one to three days after an appendectomy if the appendix did not burst and if there were no complications. If their appendix did burst, most children stay four to seven days. Children usually regain normal bowel movements after three to five days with a nasogastric (NG) tube. Intravenous (IV) antibiotics are required for at least four to seven days. Any complication, such as pelvic infection, pneumonia, or an intestinal blockage, will delay discharge.
