Clinically, the surgical grading differs according to the surgical method of appendectomy. First, if a patient undergoes traditional open surgery to remove the appendix, the surgical level is secondary surgery. In this case, the patient only needs to be treated under combined lumbar and rigid anesthesia, and the complexity of the surgery is relatively low. However, because the patient’s abdomen is accompanied by incisions, the surgery is relatively more traumatic, and the postoperative period is prone to incision infection or fat liquefaction, and recovery is slow. Secondly, if the patient undergoes laparoscopic appendectomy, the level of surgery at this time is a tertiary surgery. The patient needs to be treated under general anesthesia, and an artificial pneumoperitoneum needs to be established during the operation, and the appendix is separated and removed by special laparoscopic instruments. Laparoscopic surgery is demanding and requires special training to be able to master the surgical technique. However, the surgery is less invasive and the patient recovers faster after surgery, so it has now become the preferred surgical procedure for the removal of the appendix in clinical practice.
