Abstract Objective: To explore the clinical and MSCT features of acute appendicitis of three different pathological types: simple, suppurative and gangrenous. Methods: Retrospective analysis of the 40 cases with acute appendicitis was made from January 2018 to December 2018, including 8 simple appendicitis(20%), 25 suppurative appendicitis (62.5%), and 7 gangrenous appendicitis(17.5%). All patients underwent MSCT scanning before surgery. The manifestations of MSCT were analyzed in different pathological types of acute appendicitis in combination with clinical characteristics such as C reactive protein (CRP), procalcitonin(PCT), white blood cell(WBC) count and so on. Results: The CRP, PCT and WBC counts of gangrenous appendicitis group were higher than those of suppurative appendicitis and simple appendicitis group(P<0.05). The count of CRP, PCT and WBC in suppurative appendicitis group was higher than that in simple appendicitis group(P<0.05). In MSCT, gangrenous appendicitis is characterized by marked thickening of the appendix, local thickening of the intestinal wall, and surrounding pneumatosis. Among them, 3 cases of high-density fecal shadows were disassociated from the appendix cavity into the abdominal cavity. Suppurative appendicitis appeared with appendix enlargement with fuzzy boundary and local patchy cord-like increased density. Simple appendicitis showed mildly swelling, the space around the appendix was slightly fuzzy, and a small amount of fluid density shadow was seen in the lumen. Conclusion: The MSCT scanning combined with CRP, PCT and WBC count has important guiding significance for the diagnosis of acute appendicitis of different pathological types.
