[Ultrasound diagnostics and preoperative staging of rectal cancer].
Ultrasound (transrectal and transabdominal) examination was performed in 1991 patients. Rectal tumors were revealed in 117 (5,9%) patients, liver metastases were diagnosed in 31 (26,5%) patients. Transrectal ultrasound allowed to diagnose tumor in all examined 50 patients. Stage uT2 was diagnosed in 20 (40%) and uT3 stage of rectum cancer in 30 (60%) of patients. 10 (20%) patients revealed a pararectal lymph nodes tumor invasion. All patients were operated on. The sensitivity of the method for rectum cancer staging was 95,6%, specificity--40%, accuracy 85,7%. Sensitivity of ultrasound in pararectal lymph nodes invasion detection was 95,2%, specificity--95,0% and accuracy--92,3%.
