The purpose of this study was to evaluate possibilities of complex ultrasound examination in the diagnosis of recurrent rectal cancer. The study included 40 patients with recurrent rectal cancer, 19 men and 21 women aged from 27 to 83 years, mean age was 60+/-7.9 years. In order to detect recurrence we performed ultrasound examination with elastography of possible sites of recurrences of rectal cancer. It was found that our study showed a high diagnostic efficiency of complex ultrasound examination with elastography in the early diagnosis of recurrences and the continued growth of rectal cancer.
