[Polyposis coli. Comparison between the familial and non-familial form]

Since 1970 16 patients with polyposis coli have been treated at the Department of Surgery, Medical School, Hannover. Of these, 9 patients showed the classic type of familial polyposis, while 7 patients denied a positive family history. Comparing both groups, the nonfamilial type of polyposis coli can be separated as well from the familial polyposis as from multiple adenomas of the large bowel. Operative treatment in both groups of polyposis coli and management of nonfamilial polyposis coli are discussed.
