title: Is there an increased risk of colorectal cancer after cholecystectomy?
abstract: The incidence of cholecystectomy was not higher in 525 colorectal cancer patients than in subjects without colorectal cancer of the same age and sex living in the same region. If we did not include the persons who underwent cholecystectomy 1 or 2 years before the diagnosis or the examination was made, the number of cholecystectomy patients was the same in both groups. Right-sided and left-sided localizations of colon cancer after cholecystectomy did not differ from those without cholecystectomy. The tendency to right-sided colon cancer in women who have undergone cholecystectomy was not significant. Patients after cholecystectomy have no higher risk of colorectal cancer than persons without cholecystectomy.
