Colonoscopy is an integral part of the clinician armamentarium in the diagnosis of colorectal cancer and its precursor, the adenoma. Polypoid lesions when identified can be excised at colonoscopy and in turn reduce the risk of colorectal cancer. We prospectively evaluated the yield of colorectal cancer and adenomatous polyps by indication for colonoscopy over a one-year period. A total of 375 colonoscopies were carried out. The more common indications of colonoscopy were rectal bleeding, abdominal pain, surveillance of colorectal cancer and altered bowel habit. The highest yield for cancer was for rectal bleeding with 12.5% while surveillance of patients with a history of polyps yielded the highest percentage of new polyps. We conclude that rectal bleeding as an indication for colonoscopy yielded the highest number of cancers.
结肠镜检查是临床医生诊断结直肠癌及其癌前病变腺瘤的重要手段。结肠镜检查时发现的息肉样病变可予以切除，从而降低结直肠癌的风险。我们前瞻性评估了在一年时间内根据结肠镜检查指征发现结直肠癌和腺瘤性息肉的情况。共进行了375例结肠镜检查。结肠镜检查较常见的指征为直肠出血、腹痛、结直肠癌监测及排便习惯改变。癌症检出率最高的指征是直肠出血，为12.5%，而对有息肉病史患者进行监测时新息肉检出率最高。我们得出结论，以直肠出血作为结肠镜检查指征时癌症检出数量最多。
