Experience of Barium Enema Radiography in Mass Survey Procedure / 日本農村医学会雑誌

ABSTRACT

Local residents were screened for colorectal cancer, and the results during six year period are reported. The two-day immunological fecal occult blood test was used as the first screening method. The barium enema radiography was used as the secondary screening method even if only one of the occult blood reactions was positive. Images were acquired in varius directions from rectum to the sigmoid colon (the most common site of colorectal cancer) and at least anterior-posterior images in two directions were obtained another sites as well. Barium enema radiography is less distressing to patients than the endoscopy of entire large intestine and can be carried out quickly. In addition, its accuracy is considered comparable to that of endoscopy, and the results of our study were no poorer than that obtained in institutions where only endoscopy was carried out.
