[Ultrasonography as a supplemental technique for the diagnosis of adhesion and invasion of abdominal tumors].
Diagnostic capability of ultrasonography (US) concerning with adhesion and/or invasion of the tumors to the surrounding tissues in the abdominal region including pelvis was evaluated in 54 patients with comparison to that of CT. All the lesions reached the surface of the organ and whether the adhesion or invasion of the lesion to the surrounding organ or tissue was a problem. All the patients underwent US and CT. US was performed not only in the usual real-time manner, but with "supplemental" techniques: respiration, drinking water, rectal infusion and bimanual examination. Accuracy of US reached 72% with one or some of those four US supplemental techniques, while accuracy of CT which yields only stable image was 30% (p less than 0.005 by chi 2 test). US with suitable supplemental techniques should be applied to those cases with suspected adhesion or invasion of the tumor in the abdomen, and when CT is not reliable to judge this problem.
