Evaluation of immunochemical and chemical methods of fecal occult blood test as a screening for colorectal diseases in elderly people

结直肠癌常用的筛查手段包括大便潜血试验、乙状结肠镜检查、全结肠镜检查和钡灌肠检查等。

New methods for colorectal cancer screening include fecal occult-blood testing , flexible sigmoidoscopy , colonoscopy , and double-contrast barium enema .

结果：本组8例，5例由于不明原因出血（大便潜血试验为阳性）先后行胃镜检查12次，均未见出血灶；

RESULTS : Of the 8 patients , enteroscopy was totally performed 12 times on 5 patients due to the hemorrhage of unknown reasons , but no lesions were found .

治疗组大便潜血试验转阴时间为523±248天，对照组为710±316天，两组比较有显著性差异（P<0.01）。

The time for occult blood in stool converting negative was 523 ± 248 ( d ) in treatment group and 710 ± 316 ( d ) in control group , with a striking difference between them ( P < 0.01 ) .
