title: Duodenal villous tumors.
abstract: The treatment of 36 patients with duodenal villous tumors was reviewed to determine the long-term outcome of various surgical treatment options for specific adenoma histopathology. Duodenal villous tumors were typically solitary and periampullary in location. Villous adenomas contained epithelial atypia in 30% of patients, in situ carcinoma in 14%, and invasive carcinoma in 33%. Treatment consisted of transduodenal submucosal excision in 19 patients and radical pancreaticoduodenectomy in 15. There was no perioperative mortality. Perioperative morbidity for transduodenal excision and pancreaticoduodenectomy was 16% and 47%, respectively. Benign adenomas recurred more than 5 years postoperatively in 17% of patients undergoing transduodenal excision. Five-year survival following radical resection for invasive cancers was 45%. Overall median follow-up was 5.8 years. We conclude that duodenal villous tumors without invasive cancer can be managed successfully by local submucosal excision, but invasive carcinoma requires radical resection.
