Combined restorative proctocolectomy and pancreaticoduodenectomy for familial adenomatous polyposis.

This is a case report on FAP in a 41-year-old woman in which preoperative examination showed a giant tubulovillous adenoma of the descending duodenum surrounding the papilla of Vater, in addition to pancolon adenomatous polyposis, and isolated adenomas in the gastric antrum and corpus. As it was impossible to remove the giant villous adenoma in the duodenum endoscopically, prophylactic surgical treatment was chosen consisting of restorative proctocolectomy and additional pancreaticoduodenectomy. Flat tubulovillous adenomas in the gastric corpus were successfully removed by total snare biopsies before operation. FAP coli patients treated by prophylactic surgery are now known to be at risk of developing adenomas anywhere in the intestine and many affected patients later die from upper gastrointestinal tumors. In this single case report, the simultaneous occurrence of FAP coli and giant villous adenoma of the duodenum indicates the frequent outcome of this genetic alteration requiring lifelong surveillance. This rare case report includes a short survey of the relevant literature.
