Abstract:
Objective:To evaluate the clinical value of double contrast-enhanced ultrasonography(DCEUS)in preoperative evaluation of the circumferential resection margin（CRM）of rectal cancer.Methods:a total of 63 patients with rectal cancer confirmed by pathology were selected as the research objects.Rectal DCEUS and pelvic enhanced magnetic resonance imaging(MRI)were performed before operation,and the CRM of rectal cancer was evaluated respectively，compared with postoperative pathological results.Results:The accuracy rate,sensitivity and specificity of DCEUS in the evaluation of rectal cancer CRM were 93.65%(59/63),87.50%(14/16),and 97.87%(45/47).The accuracy rate,sensitivity and specificity of MRI were 85.71%(54/63),93.75%(15/16),and 82.98%(39/47),respectively.The specificity of DCEUS in the evaluation of rectal cancer CRM was better than that of MRI(P＜0.05).Conclusion:DCEUS can effectively evaluate the CRM status of rectal cancer before operation,and its specificity is better than that of MRI.It can be used as a good alternative method when MRI has contraindications,and has high clinical diagnostic value.
