[Diagnosis of degree of serosal invasion of carcinoma of the colon by angiography].
Angiography (AG) using Prostaglandin E1 was performed on 35 cases of carcinoma of the colon in order to diagnose the degree of serosal invasion. The findings of AG were classified into 4 groups: AG-S3, abnormal change (like irregularity and/or encasement) up to marginal vessels; AG-S2, abnormality up to vasa recta; AG-S1, abnormality of penetrating branches of vasa recta; AG-S0, no distinct findings of above mentioned vessels. 1) Diagnosis of AG is in accord with the visible postoperative findings in 82.9%. 2) Diagnosis of AG is in accord with the histopathological findings in 32.4%. 3) Postoperative examinations confirmed the AG diagnosis precisely but the conflict with histopathological findings should not be overlooked. This may be the results of inflammatory change, adhesion and fibrosis around the carcinoma of the colon.
