The best time to remove the appendix is usually about 2-3 months after the periappendiceal abscess has subsided. However, this still has to be objectively analyzed based on factors such as the degree of absorption of the inflammation in the patient’s abdominal cavity, as well as the patient’s own different physical conditions. First, if the patient’s peri-appendiceal abscess is well absorbed, the inflammation in the abdominal cavity completely subsided. The patient does not have a combination of coronary heart disease, diabetes, chronic obstructive pulmonary disease and other underlying diseases. In this case, once the periappendiceal abscess disappears, surgical removal of the appendix can be performed at any time to avoid recurrent episodes of the appendix, which can cause serious complications. Second, if the patient appendiceal abscess subsides, the abdominal cavity is still accompanied by serious infection, the patient is older, the body’s resistance is poor, and the combination of coronary heart disease, diabetes mellitus and other underlying diseases. In this case, it is recommended to perform appendectomy 3 months after the appendiceal abscess subsides, which is more conducive to the patient’s postoperative recovery and avoids the occurrence of serious complications that may endanger the patient’s life.
