Abstract

Introduction: This study aims to describe images and comment on the role of ultrasound in the diagnosis of acute appendicitis in children at Hai Phong International General Hospital from September 1, 2018 to August 31, 2020. Subjects and methods: A descriptive study of a series of patients under 16 years of age, clinically suspected, and diagnosed by abdominal ultrasound as acute appendicitis. The patient was treated with surgery, pathology or monitored, or medical treatment until stable. Convenient sampling method by taking all patients who met the above criteria were examined and treated at Hai Phong International General Hospital during the study period from September 1, 2018 to August 31, 2020. Results and Conclusions: The study included 90 pediatric patients, aged 4-15 years old; The male/female ratio was 2.24/1. Ultrasound correctly diagnosed 100% of acute appendicitis when the appendix was in a normal position and 66.7% when the appendix was in an abnormal position. Ultrasound diagnosis of appendicitis had a sensitivity of 97.5%, a specificity of 88.8%, a positive predictive value of 98.7%, a negative predictive value of 80%. Common appendicitis images were: the appendix lumen was filled with fluid, not collapsed, transverse diameter > 6 mm, RT wall thickness, probe response. Indirect sign with a high rate was fat infiltration accounting for 93.8%. Ultrasound diagnosis of complicated acute appendicitis with sensitivity 66.7%, specificity 98.6%, positive predictive value 85.7%, negative predictive value 95.9%.
