title: Angiography with epinephrine and beta receptor blocker in diagnosis of sigmoid lesions.
abstract: Various sigmoid lesions, seen on barium enema of 39 patients, were investigated with angiography of the inferior mesenteric artery using three series. The first was performed with contrast medium only, the second after use of epinephrine, and the third after a beta-blocking agent (propranolol) combined with epinephrine. The patients were followed for more than three years. Eleven carcinomas were detected, all diagnosed angiographically. Carcinoma, radiation fibrosis, and diverticulitis with fibrosis may appear similar on pharmacoangiography, but the inflammatory reaction seen, for example in diverticulitis, is different. These findings are important because they can have an influence on the indications and selection of the most suitable operation to be performed.
