Acute appendicitis refers to the acute inflammation occurring in the lumen of the appendix, which is caused by the narrowing or blockage and subsequent infection of the lumen. The primary symptom is abdominal tenderness and rebound pain, accompanied by nausea, vomiting, and fever. During the acute phase, blood tests often show an elevated white blood cell count. The main treatment is surgical removal of the appendix, with laparoscopic appendectomy being the commonly used method. This is also a minimally invasive approach to appendicitis treatment. Postoperative care is important, and it is advised to fast on the day of the surgery. Once gas passes through the rectum, a liquid diet may be resumed.
