Small Bowel Polyps and Carcinoma in Multiple Intestinal Polyposis

Two patients developed, or demonstrated, polyps of the small intestine plus adenocarcinoma, one in the jejunum, the other in the ileum, many years after colectomy for multiple intestinal polyposis. This experience, which appears to be an original observation, leads to the conclusion that the small intestines of those with multiple intestinal polyposis must be examined initially and periodically.
