The value of a scoring system based on ultrasound imaging signs in predicting the severity of acute appendicitis
Objective:To establish a scoring system for predicting the severity of acute appendicitis by analy-zing the signs of acute appendicitis under color ultrasound,and explore its clinical application value.Methods:A-cute appendicitis was divided into two groups:uncomplicated appendicitis group(151 cases)and complicated ap-pendicitis group(92 cases).The independent factors of complicated appendicitis were analyzed by univariate and multivariate logistic regression.Then,each sign assigned under ultrasound was scored,the scores of the two groups were compared,and the receiver operating characteristic(ROC)curve was drawn to explore the best score value,sensitivity and specificity of the scoring system in diagnosing complex acute appendicitis.Results:The inde-pendent factors of complex appendicitis were lumen effusion,unclear boundary,abdominal/pelvic effusion,mes-entery/omental thickening and echo enhancement,and intestinal peristalsis.The severity score of acute appendici-tis was 17 points,that of the non-complicated appendicitis group was 3.7(2.0,5.0),and that of the complicated appendicitis group was 6.84(5.0,8.7),and the difference between the two groups was statistically significant(P＜0.05).The AUC under the curve was 0.824(95％CI:0.7688-0.880,P＜0.001),the best diagnostic cut-off point was 5.5 points,that is,the score ≥6 points was diagnosed as complex appendicitis,the sensitivity was 67.4％,and the specificity was 86.8％.Conclusion:Paying attention to the independent factors of ultrasound signs of acute appendicitis is helpful for the diagnosis of complicated appendicitis.The newly established acute ap-pendicitis severity scoring system can guide the clinical evaluation of the disease.
