[Stomach and duodenal cancers in familial adenomatosis coli].

In the last years the number of patients with familial adenomatosis coli and metachrone carcinoma of the upper gastrointestinal tract is increasing. We describe two patients who, 9 and 15 years after colectomy for adenomatosis coli, developed a duodenal carcinoma. Each patient was treated with a partial duodeno-pancreatectomy. Another patient was resected prophylactically because of a diffuse adenomatosis of the duodenum three years after colectomy. We suggest that each patient with a history of colectomy for adenomatosis coli should have regular follow-ups including endoscopy of the upper gastrointestinal tract.
