Utility of flexible sigmoidoscopy as an adjunct to double-contrast barium enema examination

Abstract

DCBE is insensitive in the detection of rectosigmoid polyps. FS should continue to be used as a complementary examination to DCBE in the investigation of suspected colorectal carcinoma.

“…12 In our study, the correlation between the positive findings at flexible sigmoidoscopy and those at DCBE was good, and a significant number of small polyps not seen on DCBE were identified. Other authors have also described the inaccuracy of DCBE in the detection of rectosigmoid polyps, 15 and we support the use of flexible sigmoidoscopy as a complementary examination to DCBE in the investigation of suspected colorectal cancer.…”
