ABSTRACT： ObjectiveTo evaluate the diagnostic value of ultrasound in chronic appendicitis.MethodsA retrospective analysis was conducted on the ultrasound imaging features of the appendixes in 68 patients with chronicappendicitis（chronic appendicitis group）confirmed bypathological results at the Afiliated Hospital of Inner Mongolia Medical University from January 2023 to December 2O24，as well as 85 healthy volunteers （normal appendix group）of diferent ages with no history of abdominal pain during the same period.Multivariate Logistic regression was employed to investigate the sensitivityand specificity of diffrent variables in diagnosing chronic appendicitis.ResultsThe chronic appendicitis group had higher appendix diameter （ Z=-8.47 ， P<0.001 ）， unilateral wall thickness （ Z=-7.16 ， P<0.001 ），and submucosal thickness（ Z=-9.73 ， P<0.001 ）than the normal appendix group. Appendix diameter （ OR=3.11 ， 95%CI=1.37- 7.02， P=0.006 ）and submucosal thickness （ OR=5492.73 ，95% CI=89.53-336 984.13， P<0.001 ）were identified as independent factors for diagnosing chronic appendicitis，while gender，age，unilateral wall thickness，and intraluminal conditions had no significant impact on the diagnosis of chronic appendicitis（all P>0.05 ）. When appendix diameter combined with submucosal thickness was usedasa joint diagnosticindicator，the model demonstrated the bestperformance，with the sensitivity of 92.65% ，the specificity of 97.65% ，and the accuracy increasing to 95.42% ： ConclusionThe combined use of appendix diameter and submucosal thickness can significantly improve the accuracy，specificity，and reliability of ultrasound in diagnosing chronic appendicitis.
