The advantage of appendectomy is the avoidance of appendicitis and its complications, while the disadvantage is the possibility of abdominal adhesions after appendectomy, which may affect peristalsis. 1. Advantages: the appendix is one of the immune organs in childhood and youth, and in adulthood it has no immune function, so it can be removed without physical damage. Acute appendicitis and suppurative appendicitis are very dangerous to the body, so the biggest advantage of removing the appendix is that appendicitis and its complications, such as peritonitis, do not occur. 2. The disadvantage: after appendectomy, the inflammatory reaction will be caused by the surgical operation, and the inflammatory factor will lead to adhesion around the cecum, and the intestinal adhesion is easy to complicate intestinal obstruction.
