Abstract: ObjectiveTo probe the value of transrectum ultrasound (TRUS) in evaluating the effect of new adjuvant therapy (NAT) in treating middle-low level rectal cancer (MLLRC).MethodsTRUS was used to examine 82 cases of MLLRC before and after NAT.All cases were pathologically confirmed.The results of TRUS before and after NAT were compared.ResultsThe diagnostic rate of TRUS in MLLRC was 97.6％(80/82).The up to down range and thickness of foci of 80 cases which were detected by TRUS before NAT showed different degree diminution after NAT( P ＜0.05).The number of lymph node around rectum decreased obviously ( P ＜0.05).Only the lymph nodes of 5 cases of all lymph nodes detected by TRUS before and after NAT showed dot flow signal.ConclusionsTRUS can clearly showed the MLLRC foci,internal flow signal and lymph nodes around rectum.This is of important value in evaluating the effect of NAT,choosing the therapeutic schedule and avoiding over therapy.
