Study on the Diagnostic Value of Using CT Plain Scan to Observe the Appendiceal Wall Flooding Sign for Complicated Appendicitis
Objective To investigate the diagnostic value of observing the appendiceal wall flooding sign using CT plain scan for complicated appendicitis.Methods Retrospective analysis of 114 patients with surgically and pathologically confirmed acute appendicitis,including 31 cases of complicated appendicitis and 83 cases of uncomplicated appendicitis,between July 1,2020 and December 31,2022.Preoperative CT imaging examinations including the appendiceal wall flooding sign,diameter of appendix,abscess,phlegmon,extraluminal air,and extraluminal appendicolith were documented.Univariate and multivariate logistic regression analyses were used to evaluate the relative value of these parameters as potential predictors of complicated appendicitis.Results Features significantly related to complicated appendicitis at univariate analysis were age(P=0.003),disease time(P=0.002),diameter of appendix(P＜0.001),the appendiceal wall flooding sign(P＜0.001),phlegmon(P＜0.001),and extraluminal air(P=0.001).At multivariate analysis,the appendiceal wall flooding sign(odds ratio,98.356,P＜0.001),as well as age(odds ratio,1.069,P=0.014),were independent risk factors for complicated appendicitis.The appendiceal wall flooding sign for complicated appendicitis showed an area under the receiver operating characteristic curve of 0.894.Conclusion The observation of the appendiceal wall flooding sign by CT plain scan has important diagnostic value for complicated appendicitis.
