title: An evaluation of a direct access flexible fibreoptic sigmoidoscopy service.
abstract: During a 3 year period 146 general practitioners referred 630 patients to a direct access flexible sigmoidoscopy clinic. The yield was 53.3% with significant colonic or rectal pathology in 30%. Twenty six cancers, 4 Dukes' A, and 38 patients with symptomatic adenomatous polyps were detected. Five further cancers were detected by subsequent barium enemas. The service reduced delay in diagnosing colorectal pathology but did not reduce the number of barium enemas requested by general practitioners. It is suggested that where facilities are already available, such a service to investigate rectal bleeding in patients over 40 years is of benefit both to patients and general practitioners.
