The duration of pain after laparoscopic appendicitis surgery varies according to the severity of the condition. Acute simple appendicitis generally relieves the pain on the second day after surgery, with only some mild pain felt at the surgical incision. Appendiceal lesions are more serious, such as periappendiceal abscess and appendiceal perforation, the postoperative pain will be longer, periappendiceal abscess and appendiceal perforation may also need to be placed on the drainage strip, the abdominal cavity to drain out the pus, so the patient may still have pain for 3-5 days, because the patient’s abdominal cavity inflammation is absorbed need a certain amount of time, and the pain can only be relieved after the inflammation is completely absorbed.
