Abstract:
Objective To evaluate the diagnostic accuracy of ultrasound miniature probe(UMP)examination in tumor invasion(T staging) and local lymphatic node metastasis(N staging) for colorectal carcinoma. Methods Preoperative UMP examinations(12 MHz) were performed on 53 patients with colorectal carcinoma undergoing surgeries.The diagnosis accuracy of UMP examination in T and N staging was determined by comparison of the results of operation exploration and histopathologic findings. Results The accuracy in T staging for colorectal carcinoma was 86% with UMP examination,and that for early stage colorectal carcinoma was 100%.The accuracy,sensitivity and specificity in N staging for colorectal carcinoma were 81%,77%,and 84%,respectively with UMP examination. Conclusion UMP examination works well in determining T stage of colorectal carcinoma,especially for early stage colorectal carcinoma and those with tumor stenosis.
