SANCHEZ, A. et al. The value of colonoscopy to assess rectal bleeding in patients referred from Primary Care Units. Rev. esp. enferm. dig. [online]. 2005, vol.97, n.12, pp.870-876. ISSN 1130-0108.

Objectives: rectal bleeding is very common in the general population. It is produced mainly because of benign disease originating in the anus and the rectum. Our aim was to evaluate the need for colonoscopy in patients presenting with rectal bleeding. Patients and methods: patients referred from Primary Care Units and complaining of rectal bleeding were included prospectively in a three-month study. All patients underwent a careful medical history along with physical examination, laboratory tests, and colonoscopy. Results: 126 patients with a mean age of 49.2 years (range: 19-80) were studied. Rectal digital examination was abnormal in 75 cases (59.5%). Severe disease was encountered in 22 patients (neoplasm, angiodysplasia, and inflammatory bowel disease); 10 patients had polyps, 6 had colorectal cancer, and 6 had inflammatory bowel disease. Out of 63 patients younger than 50 years, 5 had severe disease, all of them in the form of inflammatory bowel disease. Conclusions: a neoplasm of the rectum and colon in patients younger than 50 years is a rare event. A colonoscopy must be performed in this group of patients to rule out inflammatory bowel disease.
