Diagnosis value in the elderly patients with colorectal tumor by color Doppler ultrasonography

Objective To explore the diagnosis value in the elderly patients with colorectal tumor by color Doppler ultrasonography.Methods A total of 93 cases with colorectal tumor in elderly patients diagnosed by color Doppler ultrasonography were retrospectively analysed and the results were to compare with those with surgical pathology.Results In 93 cases of colorectal tumor,the qualitative diagnostic accurate rate of color Doppler ultrasonography and pathology was 95.7%(89 /93) ;the location diagnostic accuracy was 91.4%(85 /93).All cases showed the irregular arterial blood flow signal.Color Doppler ultrasonography can accurately diagnose the following diseases(e.g.lesions under the mucous membrane of the colon,exogenous type of tumor,abdominal lymph node metastasis and liver metastasis).The accuracy were 91.3%,100% and 83.3%,respectively.Conclusion The color Doppler ultrasonography in colorectal cancer is a noninvasive and effective method which can not only showed the position and size,statistical information,but also the intestines and parenteral transfer situation by internal blood flow.The color Doppler ultrasonography for diagnosis in colorectal tumor in elderly patients had higher value which can be the first choice and provide a reliable basis for treatment.
