Abstract

We report our personal experience on endorectal US and CT in the preoperative staging of rectal carcinoma. Our series includes 64 cases (38 male and 26 female) evaluated with intrarectal sonography; 38 of these patients underwent also CT-study of the lower abdomen. Using both imaging techniques infiltration of the rectal wall and adjacent structures and lymphonode involvement were studied. The results of our study refer to 58 patients who underwent endorectal US, 31 of whom studied also with CT. Referring to the T-parameter with ultrasound 41 correct diagnosis were obtained, in 13 cases the lesion was overstaged and in 4 cases understaged. The sensitivity, specificity and diagnostic accuracy was respectively 89,5%, 60% and 73,3%. With CT 23 diagnosis were correct, in 1 case the lesion was overstaged and in 7 cases understaged; sensitivity, specificity and diagnostic accuracy concerning rectal wall infiltration were respectively 72%, 83.3% and 74.2%. The evaluation of the N-parameter demonstrated low value of sensitivity with both US (15.8%) and CT (42.9%). Considering the results of our series, we feel that it is necessary to use both imaging techniques because results obtained are coplementary referring to the T-parameter, although N-parameter were a little significant.
