Appendicitis is a common acute abdominal condition that can also be life-threatening if left untreated and allowed to progress. Most patients with appendicitis can be relieved and completely cured with normal treatment. If the condition is not treated or is not actively treated, it can further turn from inflammation to suppurative appendicitis, and a diffuse infection can form in the abdominal cavity. Especially in appendicitis caused by intestinal stone obstruction, due to the thickening and thickening of the appendiceal canal wall, the pressure in the intestinal cavity increases, the more fragile canal wall is likely to be perforated, and the intestinal stone in the appendix may also be dislodged into the abdominal cavity, resulting in diffuse peritonitis, which is a very serious infection at this time and can be life-threatening if not treated in time.
