title: [Sonography in tumors of the rectum].
abstract: The authors evaluate the contribution of endorectal sonography in malignant diseases of the rectum and rectosigmoid as regard assessment of the stage of the disease. The examination is fully indicated in all tumours with the exception of very low and very stenotic processes. It provides objective information on the penetration of the tumour into neighbouring tissues and organs and of the tumour size. It is a very economical method which does not cause discomfort to the patient and it is quite safe. It permits evaluation of the effectiveness of adjuvant therapy and early diagnosis of local relapses, in particular in conjunction with continual evaluation of the CEA level.
