The length of hospital stay after appendicitis treatment varies greatly depending on the individual's constitution, the severity of the appendicitis, and the method of treatment used. If the symptoms are mild and only conservative medication treatment is chosen, then you can be discharged after the symptoms disappear. If surgical treatment is chosen, then it's typical to observe for three to five days post-surgery; if there are no significant signs of infection or pus formation, then discharge can be considered, followed by observational treatment. If there is significant pus formation, or cases of gangrene or perforation that lead to severe peritonitis, routine anti-infection treatment should be administered post-surgery. Therefore, the treatment period may be longer, requiring a waiting period until the inflammation is completely resolved before discharge.
