Clinical Value of Endorectal Ultrasonography in Preoperative Staging and Sphincter-preserving Surgery of Middle and Low Rectal Cancer
Objective To explore the clinical value of preoperative TN staging and sphincter-preserving of middle and low rectal cancer by endorectal ultrasonography(ERUS).Methods A total of 178 patients with middle and low rectal cancer admitted to the Peo-ple's Hospital of Inner Mongolia Autonomous Region from January 2015 to January 2023 underwent ERUS examination before surgery.x2 test was used to compare the imaging features of ERUS,clinicopathological features and sphincter-preserving in patients with middle and low rectal cancer.Using postoperative pathology as the gold standard,the accuracy of ERUS in preoperative evaluation of TN staging of middle and low rectal cancer was analyzed.Using clinical operation as the standard,the accuracy of ERUS in preoperative evaluation of sphincter-preserving for middle and low rectal cancer was analyzed.Results Pathological T stage,pathological differentiation degree,infiltration depth of tumor,distance of lower tumor margin from anal margin and ultrasonic T stage had statistical significance in the selec-tion of surgical program for middle and low rectal cancer(P＜0.05).Compared with the actual pathological results,the T stage of middle and low rectal cancer assessed by ERUS before surgery was highly consistent(Kappa=0.730,P＜0.001),and the N stage assessed by ERUS before surgery was moderately consistent(Kappa=0.524,P＜0.001).Compared with the actual surgical procedure,the preoper-ative surgical protocol assessed by ERUS before surgery was highly consistent(Kappa=0.676,P＜0.001).Conclusion ERUS exami-nation has high accuracy in preoperative TN staging assessment of middle and low rectal cancer,and preoperative assessment of sphincter-preserving is highly consistent with clinical practice,which can be used as a clinical reference.
