DEVELOPMENT OF INVASIVE ADENOCARCINOMA FOLLOWING COLECTOMY WITH ILEOANAL ANASTOMOSIS FOR FAMILIAL POLYPOSIS-COLI - REPORT OF A CASE

PURPOSE: Proctocolectomy with ileoanal anastomosis has gained increasi ng acceptance for the prophylactic treatment of patients with familial polyposis coli. Longterm surveillance of the ileal pouch and the pouc h-anal anastomosis has not been emphasized despite concern regarding r etained rectal mucosa following the procedure. METHODS: A 34-year-old patient with a strong family history of familial polyposis coli was tr eated at 14 years of age by single-stage proctocolectomy with straight ileoanal anastomosis. Follow-up proctoscopic examinations revealed de velopment of adenomatous changes at the ileoanal anastomosis. RESULTS: This report presents a patient with familial polyposis coli who devel oped invasive adenocarcinoma at the ileoanal anastomosis 20 years afte r proctocolectomy with ileoanal anastomosis. CONCLUSIONS: We stress th e need for lifelong proctoscopic surveillance in patients with familia l polyposis coli treated by proctocolectomy with ileoanal anastomosis.
