Radiological Findings of Minute and Small Depressed Colorectal Neoplasm

Abstract

We are required to detect colorectal cancer at the early stage in order to improve its prognosis. Minute cancers are an early cancer and are detected as a depressed lesion. We could demonstrate small and minute depressive cancers(4 lesions) and adenomas(6 lesions) emploing a new preparation of barium enema. This preparation consists of bisacodyl 15mg, massive isotonic citrated magnesium solution (25m 1/b.w. kg), cysapride 15mg and a low-fat, low-residue meal. Ten depressed lesions (3 lesions ranging between 1 cm and 0.6 cm, 7 lesions of less than 0.6 cm) were demonstrated by double contrast method. Findings of those depressed lesions were demonstrated as a radiolucent area around a faint barium fleck.
