Acceptance and outcome of endoscopic screening for colonic neoplasia in patients undergoing clinical rehabilitation for gastrointestinal and metabolic diseases.
Our purpose was to study the acceptance and the outcome of endoscopic screening investigations of the colon in patients between 50 and 60 years of age in a clinical rehabilitation center. A total of 1,166 patients (m = 691, f = 475) entered the study. After guaiac testing all patients for fecal occult blood loss (FOBT), 667 patients (57%; m = 407, 61%; f = 260, 39%; n.s.) accepted a sigmoidoscopy. Of 658 (m = 403, f = 255) patients with complete investigation, 153 (23%) (m = 104, 26%; f = 49, 19%; n.s.) had a total of 272 neoplastic polyps, including 1 carcinoma. Adenomas = /> 10 mm were found exclusively in male patients (n = 25, p < 0.001). In comparing patients aged 50-55 years (n = 386) with those aged 56-60 years (n = 272), prevalences of neoplasia were found to be 19%/29% (p < 0.01), and prevalences of adenomas = /> 10 mm were 2%/10% (p < 0.05). The acceptance of a colonoscopy in patients with neoplastic polyps at sigmoidoscopy was 116/153 (m = 78, 75%; f = 38, 78%; n.s.). In 39 of these patients (34%) (m = 31, 40%; f = 8, 21%; p < 0.05), 68 further adenomas were detected but no carcinoma or adenoma with severe dysplasia. Multiple adenomas in the proximal colon were seen in 17 cases (15%) (m = 16, 21%; f = 1.3%; p < 0.01). The FOBT was positive in 10/658 patients, including the case with a carcinoma, but only in 4/25 with adenomas = /> 10 mm. In 5 cases with positive FOBT sigmoidoscopy and complementary colonoscopy did not reveal any pathology.
