[Computed tomographic diagnosis of rectal tumors].
Perirectal spreading of rectal carcinoma is significant for their therapy. Moreover, possible metastasis of the regional lymph nodes and/or of the liver must be detected before therapy. For preoperative staging CT-investigations in 52 patients were performed. For the tumour stages pT1 and pT2 correct CT-staging was achieved in 60% of the cases. CT-information on lymphogenic metastases is not satisfactory, liver metastases were detected with a sensitivity of 72%. 56 patients were investigated after abdominosacral rectum ablation. In 34 cases no local recidivation was detected, but 3 cases of liver metastases were found, also one metastasis of the kidney. Of 22 patients with regional recurrences 5 had liver metastases. 3 cases of lymphogenic metastasis were found.
