The cost-effectiveness of two colon cancer-screening strategies was compared. The first strategy mirrors the recommendations of the American Cancer Society and includes sigmoidoscopy starting at age 50, and yearly fecal occult blood testing. The second strategy is screening with colonoscopy. ⋯ The calculated cost of preventing one death from colon cancer is $444,133 with sigmoidoscopy versus $347,214 with colonoscopy. In conclusion, colon cancer prevention with current screening methods is very costly. Screening with sigmoidoscopy and fecal occult blood testing may not be cost-effective, compared to screening with colonoscopy.

Case ReportsMagnetic resonance imaging of an esophageal duplication cyst.
A confirmed case of an esophageal duplication is reported. We review the clinical and pathologic features of this rare anomaly, and describe its appearance on magnetic resonance imaging (MRI). The potential advantages of utilizing MRI in the diagnosis of suspected esophageal duplications, and in the detection of any associated lesions, are outlined.
