Both colonoscopy and barium enema are important techniques for examining the colon for polyps and cancer. They are approximately equally sensitive in detecting polypoid lesions of 7 to 10 mm or larger. A major limitation of colonoscopy is that the cecum cannot be visualized in 10 to 36% of cases. The comparable accuracy for detecting significant lesions, greater safety, and greater cost-effectiveness of barium enema favor its use in most patients.
结肠镜检查和钡灌肠都是用于检查结肠息肉和癌症的重要技术。它们在检测7至10毫米或更大的息肉样病变方面的敏感性大致相同。结肠镜检查的一个主要局限性是，在10%至36%的病例中无法观察到盲肠。钡灌肠在检测重大病变方面具有相当的准确性、更高的安全性和更高的成本效益，这使得它在大多数患者中更受青睐。
