Effectiveness of Double Contrast Barium Enema in Colon Examinations

The colonic cancer is one of frequent cancers in Korea and the incidence of colon cancer has been increasing. We have compared sigmoidscopy, colonoscopy, barium enema and abdominal CT studies one another to examine the characteristic of colon tumors in order to see if we can improve the colonic Barium Enema method. The study was done from March 1st through August 10th in 2005 for 30 patients who came to our institution with various symptoms and for whom more than two studies among barium enema, sigmoidoscopy, colonoscopy and abdominal CT had been performed with the resultant diagnosis of polyps or cancers. There were 2 patients in whom positive barium enema but with negative sigmoidoscopic exams, 1 patient in whom positive barium enema but negative colonoscopic exams, 0 patient in whom positive barium enema and also positive abdominal CT exams and 0 patient in whom negative sigmoidoscopy, colonoscopy and abdominal CT and also negative barium enema. Therefore we have concluded that the sensitivity of the double contrast barium enema reveals no less sensitivity than endoscopic examinations and also the former has been found to be more cost effective.
