The diagnostic value of low-frequency ultrasound combined with high-frequency ultrasound in hyperplastic of the gallbladder

Objective To explore the clinical value of low- and high- frequency ultrasound in the diagnosis of benign lesions of the gallbladder.Methods A retrospective analysis was performed in 110 outpatients with pathologically confirmed benign lesions of the gallbladder in our hospital from January 2015 to January 2016. All patients were examined with low- frequency ultrasound,and the results were recorded. Then,they were examined with a combination of low- and high- frequency ultrasound,and the results were recorded. The rate of agreement with pathological diagnosis was compared between the two examination methods. The chi- square test was used for comparison of categorical data between groups. Results In the 110 patients,83 had the low- frequency ultrasound results in accordance with pathological diagnosis; 102 had the low- and high-frequency ultrasound results in accordance with pathological diagnosis,consisting of 70 cases of polypoid lesions of the gallbladder( 68. 63%) and32 cases of adenomyomatosis of the gallbladder( 31. 37%). Eight( 7. 3%) of the 110 patients were misdiagnosed by the combined examination.The rate of agreement with pathological diagnosis of the combined examination( 92. 73%) was significantly higher than that of low- frequency ultrasound( 75. 45%)( χ2= 12. 666,P = 0. 001). Conclusions A combination of low- and high- frequency ultrasound helps increase the diagnostic rate for benign lesions of the gallbladder.
