title: [Gastroduodenal polyposis in patients with familiar adenomatous polyposis after rectocolectomy].
abstract: BACKGROUND
  The extra colonic manifestations, like upper gastrointestinal tract polyps and duodenal cancer are disorders that affect long-term morbidity and mortality of patients with familial adenomatous polyposis, after rectocolectomy.
  
  
  OBJECTIVE
  To describe the frequency of those disorders in patients with familial adenomatous polyposis and to review efficacy of upper gastrointestinal endoscopic surveillance.
  
  
  METHODS
  Between 1984 and 2005, 62 patients with familial adenomatous polyposis after rectocolectomy, were studied retrospectively, by Coloproctology Group, Medical Sciences Faculty, State University of Campinas, SP, Brazil. It was possible to analyze 53 patients (85,5%) in this study.
  
  
  RESULTS
  Twenty seven (50,9%) of 53 patients in follow-up had upper gastrointestinal polyps. Eight (15,4%) had gastric adenomatous polyps, 14 (27%), duodenal polyps and 5 (9,6%) duodenal and gastric polyps. Two patients (3,8%) had adenomatous duodenal polyps with severe dysplasia, and one (1,9%) had adenocarcinoma of the duodenal papilla.
  
  
  CONCLUSIONS
  The upper gastrointestinal endoscopic surveillance has importance and the aim is to detect as early as possible the occurrence of duodenal adenocarcinoma and upper gastrointestinal polyps with severe dysplasia.
