Minimally invasive surgery for appendicitis mostly refers to laparoscopic appendectomy, and how long it takes is not fixed, but mainly depends on the patient’s condition. For those with mild inflammation, the operation is relatively simple and takes between half an hour and an hour, while those with severe conditions are more difficult to operate and the operation can take longer, more than an hour. 1. In mild appendicitis, although there are congestion, edema, exudation and other changes in the appendix due to bacterial infection, the lesions are relatively limited, so when performing minimally invasive appendicitis surgery, only the localization of the appendix can be treated. The operation takes between half an hour and one hour. 2. Severe appendicitis, gangrene, perforation of the appendix and the formation of periappendiceal abscesses, some of which can lead to peritonitis, the operation is not easy to operate, the difficulty factor is greater, so the minimally invasive surgery time is also longer, more than one hour. The specific time, and the attending physician’s operating proficiency also has a certain relationship, need to be specialized physicians for specific conditions.
