Acute appendicitis is a common disease in general surgery. The typical clinical manifestation is a vague pain in the upper abdomen or around the umbilicus, which shifts to the right lower abdomen after a few hours, often accompanied by loss of appetite, nausea, vomiting, and fever. If acute appendicitis is not treated early, the appendix may become perforated and septic, causing serious complications such as diffuse peritonitis and a high mortality rate. Once the patient has appendicitis perforation, he needs to be actively given surgical treatment. During the operation, the pus and feces in the abdominal cavity should be suctioned with suction devices, and adequate drainage should be achieved, and the pus in the abdominal cavity should be wiped clean after the appendix is removed.
