A paraprosthetic-enteric fistula associated with a duodenal tumor.

An unusual etiology and presentation of a paraprosthetic-enteric fistula is reported involving a duodenal tumor. Review of the possible mechanisms of graft-enteric fistula formation and diagnostic evaluation is presented. Initial insertion of an extraanatomic bypass followed by graft excision was performed in the present case and is encouraged in hemodynamically stable patients. Additionally, resection of the eroded duodenum with end-to-end anastomosis was performed in order to restore intestinal continuity.
