DÜZ BAĞIRSAQ XƏRÇƏNGİNİN DİAQNOSTİKASINDA ULTRASONOQRAFİYANIN İMKANLARI

Abstract

The article presents information about the results of rectal USG in the diagnosis of rectal cancer (RC). For this purpose, the results of USG were analyzed in 49 patients with rectal cancer. Among them, rectal cancer had stage T1 in 2 patients, stage T2 in 11 patients, stage T3 in 27 patients, and stage T4 in 9 patients. In 4 patients, the tumor was predominantly polypoid, in 39 - ulcerative-infiltrative, in 6 - exophytic. It was shown that the ulcerative-infiltrative form of rectal cancer occurs significantly (p<0.001) more often (79.6±5.8%). Late stage of rectal cancer (T3+T4) was diagnosed in 73.5%, and early stage in 26.5% (p<0.001) of cases. Ultrasound of the rectum revealed an early stage of rectal cancer in 11 (22.4±6.0%) patients, and in 5 (10.2±4.3%) patients with computed tomography. Metastases in the pelvic lymph nodes were detected by CT in 23 (74.2±7.9%) patients, by ultrasound in 8 (25.8±7.9%) patients (p<0.001). Based on the conducted studies, it can be concluded that rectal ultrasound is more effective than computed tomography in the early stage of rectal cancer. However, computed tomography detects pelvic lymph node metastases better than rectal ultrasound.
