title: Cholecystectomy and right-sided colon cancer.
abstract: The present study conducted in order to determine the association between cholecystectomy and colon cancer. Two groups of subjects were investigated: 478 patients who underwent cholecystectomy and 492 clinically healthy persons. The method chosen was the screening for colorectal cancer by means of detecting occult blood in the feces using Hemoccult test. In the cholecystectomy group two right-sided and in the control group two left-sided colon cancers were detected. These data support the hypothesis that cholecystectomy may be a predisposing factor in the development of right-sided colon cancer.
