The absence of gas and fluid accumulation in the appendiceal intestinal canal indicates that the appendix is still morphologically and structurally sound and has not progressed to suppurative appendicitis, while surgery is required if suppurative appendicitis develops. In general, when the appendiceal intestinal lesion occurs, combined with the patient’s metastatic right lower abdominal pain and other symptoms, appendicitis disease can be considered. Acute suppurative appendicitis is the main consideration if a CT scan of the abdomen shows pneumoperitoneum near the appendiceal tube, exudate around the appendix, or periappendiceal edema. Acute suppurative appendicitis requires emergency surgery to prevent further progression to perforated ulcers and abdominal infection. Although there is no pneumoperitoneum in the appendiceal intestinal canal, it is still necessary to pay attention to clinical symptoms, such as metastatic right lower abdominal pain, nausea and vomiting, etc., to be alert to the occurrence of appendicitis.
