Appendiceal cellulitis, in fact, is purulent appendicitis. Cellulitis is mainly a diffuse purulent inflammation of loose connective tissue, in which the best sites are the skin, muscle and appendix. Pathology microscopically reveals a large neutrophilic infiltrate and exudate with varying degrees of necrosis and pus formation. If the appendix is viewed surgically through a minimally invasive laparoscope, the septic appendix can be seen to be abnormally swollen with an expanded and red surface, with a large amount of pus moss collecting and adhering, which is milky white and will adhere to the appendix and the nearby intestinal omentum peritoneum, and there will be peripheral abscess formation. Therefore, surgical removal of suppurative appendicitis is the best treatment, and postoperative treatment with full anti-inflammatory therapy has a high cure rate and fewer complications.
