In clinical practice, the appendix belongs to the digestive system and the appendix also has endocrine functions, so the appendix has considerable importance in the human body. However, it should be noted that the appendix is most prone to inflammatory lesions. If patients develop inflammation of the appendix, they will experience pain in the right lower abdomen, and some patients may even experience nausea, vomiting, fever and other discomforts, and some patients may even develop diffuse peritonitis, which affects the life of patients. Therefore, once the patient’s appendix becomes inflamed, anti-infection treatment needs to be actively given and surgical removal is required. Nowadays, laparoscopic appendectomy is commonly used, which is less traumatic for the patient and the chance of postoperative complications is particularly rare, and the hospital stay is also short. In addition, cancer of the appendix is a very rare phenomenon, but it must be taken seriously. Once a patient develops appendiceal carcinoid tumor or cancer of the appendix, a combination of chemotherapy, radiation therapy and surgery is required.
