Appendicitis cannot be seen by taking X-rays, because the most common diagnostic method in the clinical diagnosis of appendicitis is physical examination by pressing on the McKenicke’s point, which is the outer and outer 1/3 of the line between the umbilicus and the patient’s right anterior superior iliac spine. The patient’s clinical manifestations, such as fever, vomiting, diarrhea, and other clinical symptoms, are combined with blood tests that show elevated white blood cells, neutrophil ratio, C-reactive protein, and other inflammatory indicators. In addition, the presence of appendicitis can be diagnosed with ultrasound examination, which can clearly visualize the swelling of the appendix, local exudation, and fluid accumulation in the abdominal cavity and pelvis.
