Familial polyposis coli and periampullary malignancy

Abstract
Patients with polyposis coli have an increased risk of developing periampullary malignancies, particularly if duodenal polyps are present. Since periampullary neoplasms occur, on the average, 15 yr following the initial diagnosis of colonic polyps, periodic follow-up radiologic studies of the upper gastrointestinal tract are necessary in the management of polyposis coli.
