“…The sensitivity, accuracy, and false negative of high-frequency ultrasound in the diagnosis of acute appendicitis were significantly higher than that of low-frequency ultrasound. After statistical x 2 test, the p value was <0.05, which was statistically significant [ 20 ]. The results are shown in Figure 2 .…”

In order to study the practical application value of abdominal ultrasonography in the diagnosis and treatment of acute abdomen in children, this study uses the method of collecting clinical actual cases and scientific analysis to estimate the clinical diagnostic value of high-frequency ultrasound and low-frequency ultrasound. In order to further clarify its curative effect and treatment advantages, a retrospective analysis of medical records was conducted, and 95 children with acute abdominal pain and suspected appendicitis who were admitted to a hospital from September 2021 to November 2021 were reviewed. ATIL HD15000 color Doppler ultrasound was used for diagnosis. The results are as follows: the sensitivity, specificity, positive predictive value, and negative predictive value of low-frequency probe in the diagnosis of intussusception in children were 83.61%, 73.33%, 92.73%, and 52.38%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value in the diagnosis of mesenteric lymphadenitis were 80.00%, 81.97%, 52.17%, and 94.34%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of high-frequency probe in the diagnosis of intussusception in children were 93.44%, 80.00%, 95.00%, and 75.00%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value in the diagnosis of mesenteric lymphadenitis were 93.33%, 95.08%, 82.35%, and 98.31%, respectively. Among the children with appendicitis confirmed by operation and pathology, 69 cases were detected by high-frequency ultrasound and 4 cases were missed (including 3 cases of acute simple appendicitis and 1 case of perforated appendicitis). The false negative was 4%, there was no false positive, and the sensitivity, specificity and accuracy were 95%, 100%, and 96%. In the same cases, 28 cases were detected by low-frequency ultrasound, 45 cases were missed, the false negative was 61%, and there was no false positive. The sensitivity, specificity, and accuracy were 39%, 100%, and 53%. The sensitivity, accuracy, and false negative of high-frequency ultrasound in the diagnosis of acute appendicitis were significantly higher than that of low-frequency ultrasound. This study shows that ultrasound has high accuracy, sensitivity, and specificity in the diagnosis of acute appendicitis. Low-frequency ultrasound can show the whole picture of the disease and the situation in the abdominal cavity, which can better guide the clinical treatment. Color Doppler hemodynamics is a useful supplement to two-dimensional ultrasound, and ultrasound also plays a positive role in the differential diagnosis of acute appendicitis in children.
