Abstract:
Objective To discuss the value of ultrasonic miniature probe (UMP) in the preoperative staging of colorectal cancer.Methods Sixty-one colorectal cancer patients were examined before operation using the UMP (Olympus UM-2R,12 MHz).According to the intestinal wall structural layers and the close organic infiltration,the tumor encroaching depth was judged and the diagnosis of the T stage was made.All cases got the pathological verification,which was compared with the stage of UMP.Results The general diagnostic accurate rate of tubal wall encroaching depth (T stage) by the UMP was 86.9% (53/61) in the colorectal cancer and the diagnostic accurate rate was 100.0% (3/3) in the early stage cancer.UMP stage and TNM stage showed a better consistency (Kappa=0.790).Conclusions UMP has high accurate rate in the judgment of the colorectal cancer encroaching depth.There is some value in the T stage diagnosis before operation,which could help patients with colorectal cancer select suitable therapies.
