Abstract:
Objective To observe the value of ultrasound combined with hematologic tests for diagnosing acute complicated appendicitis.Methods Data of 225 patients with acute appendicitis confirmed by surgery and postoperative pathology were retrospectively analyzed.The patients were divided into acute complicated appendicitis group(complicated group,n=33)and acute uncomplicated appendicitis group(uncomplicated group,n=192)based on operational and post operation pathological findings.Clinical data,hematologic test results and ultrasound findings before operation were compared between groups.Multivariate logistic regression was used to construct a combination model for diagnosing acute complicated appendicitis.Receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to evaluate the diagnostic value of predictive factor alone and their combination for diagnosing acute complicated appendicitis,which were then compared with DeLong test.Results Compared with uncomplicated group,patients in complicated group were older,with higher proportion of fever and vomiting,higher level of C reactive protein(CRP)and of neutrophil-to-lymphocyte ratio(NLR),larger external diameters of appendix,also higher proportion of appendiceal intracavitary fecalith and periappendiceal abscess(all P＜0.05).Multivariate logistic regression analysis showed that elevated serum CRP and NLR,increased external diameter of appendix and periappendiceal abscess were all predictive factors of acute complicated appendicitis(all P＜0.05).The diagnostic efficiency of logistic regression model constructed based on the above factors(AUC=0.854)was higher than that of each single predictive factor alone(Z=2.548-4.527,all P＜0.05).Conclusion Ultrasound combined with hematologic tests had high value for diagnosing acute complicated appendicitis.
