Ordinary appendicitis surgery can be completed in about 15-60 minutes, while the time required for more complex appendicitis surgery cannot be generalized. Acute appendicitis surgery is one of the common emergency clinical procedures in which patients usually have periumbilical pain, metastatic right lower abdominal pain, and unbearable pain. In general, simple acute appendicitis surgery is relatively simple and takes about 60 minutes, including preoperative preparation, preoperative anesthesia, and intraoperative operations. However, for purulent appendicitis and gangrenous perforated appendicitis, the patient’s signs are heavy, the abdominal cavity is complicated, and there may be inflammation spreading and adhesions in the abdominal cavity, so the operation takes longer, some of them can take 3-4 hours or even longer. It is important to go to the hospital for surgery in a timely manner when symptoms like appendicitis appear to avoid delaying the condition and turning a simple appendicitis surgery into a more complicated and dangerous one.
