Appendicitis is one of the very common acute abdominal diseases in clinical practice. Patients with the following conditions must undergo surgery in a timely manner: 1. The appendix is embedded with a fecal stone, which causes a significant increase in pressure in the appendix cavity, and the patient has severe right lower abdominal pain. Through simple conservative anti-infection treatment, the patient’s abdominal pain symptoms cannot be improved and local infection can be controlled. At this time, timely surgical treatment must be performed to remove the appendix and fecal stones in order to achieve better results. 2, the patient’s appendix has been perforated, the pus in the appendix continues to seep into the abdominal cavity, and the patient has acute diffuse peritonitis. In this case, it is also necessary to perform surgery in time to clean up the abdominal cavity to avoid serious complications such as infectious shock. 3. When a pregnant woman has acute suppurative appendicitis near the time of delivery, it is recommended to perform surgery to remove the appendix as soon as possible and perform a cesarean section at the same time to avoid serious infection in the abdominal cavity, which can affect the survival of the fetus.
