Abstract:
30 patients with colorectal carcinoma underwent endoscopic ultrasonography(EUS)and microvessel counting for staging before operation.The accuracy of EUS in assessing depth of tumor in- filtration was 76.7%,that in detecting lymph node involvement being 73.3%.The correctness of pre- operative Duke's staging remained 70%.Microvessel counting correlated with depth infiltration and lymph node invasion.The microvascularity in tumor with serosal involvement was obviously abundant than that without,so as in tumor with and without lymphatic invasion.The results revealed that both EUS and microvessel counting can be considered as an essential evidence for preoperative staging of col- orectal cancer and thereby for predicting prognosis.
