Abstract:
Objective:To investigate the clinical efficacy of qualitative and staging diagnosis of rectal tumors with dual contrast-enhanced ultrasonography and interventional biopsy.Methods:A total of 300 patients with rectal tumors who received treatment in The First People's Hospital of Huzhou from December 2019 to March 2022 were included in this study. All patients underwent dual contrast-enhanced ultrasonography and interventional biopsy followed by focus resection. Taking the postoperative histopathological test results as the gold standard, the efficacy of dual contrast-enhanced ultrasonography and interventional biopsy in the localization, qualitative analysis, and staging of rectal tumors was analyzed.Results:The compliance rate of dual contrast-enhanced ultrasonography and interventional biopsy in the localization of rectal tumors was 100%. The sensitivity, specificity, and accuracy of the dual contrast-enhanced ultrasonography and interventional biopsy for qualitative diagnosis of rectal tumors were 94.8%, 97.8%, and 96.7%, respectively. The Kappa value used for assessing agreement in the qualitative diagnosis of rectal tumors between dual contrast-enhanced ultrasonography and interventional biopsy and postoperative tissue pathological examination results was 0.947. The area under the curve plotted for qualitative diagnosis of rectal tumors was 0.974. The sensitivity, specificity, and sensitivity of dual contrast-enhanced ultrasonography and interventional biopsy for diagnosis of stage I-III rectal cancer were 94.1%-97.8%. The Kappa values used for assessing agreement in staging diagnosis of stage I-III rectal cancer between dual contrast-enhanced ultrasonography and interventional biopsy and postoperative tissue pathological examination results were 0.923, 0.912, and 0.927, respectively. The areas under the curve plotted for staging diagnosis of rectal cancer were 0.961, 0.955, and 0.970, respectively.Conclusion:Dual contrast-enhanced ultrasonography and interventional biopsy have a high efficacy in the localization, qualitative diagnosis, and staging diagnosis of rectal tumors.
