The symptoms are nonspecific. Only a high index of suspicion will lead to early diagnosis. Life\u2010threatening complications and increased incidence of malignant transformations are associated with delayed diagnosis. This paper reviews 11 patients (nine previously unreported) with villous tumor of the ampulla of Vater and two with this neoplasm in the duodenum. It also reviews the important principles of management illustrated by the behavior of the tumors of these 11 patients compared to those of previous reports. For favorable results, all lesions must be excised in toto and evidence of invasive malignancy must lead to aggressive treatment whenever feasible.<\/jats:p>","DOI":"10.1002\/jso.2930330414","type":"journal-article","created":{"date-parts":[[2007,2,20]],"date-time":"2007-02-20T10:43:39Z","timestamp":1171968219000},"page":"268-272","source":"Crossref","is-referenced-by-count":4,"title":["Villous tumors of the duodenum and ampulla of vater"],"prefix":"10.1002","volume":"33","author":[{"given":"Cihangir","family":"Celik","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Joseph A.","family":"Venditti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sateesh","family":"Satchidanand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duane T.","family":"Freier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,7,19]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19840701)54:1<65::AID-CNCR2820540115>3.0.CO;2-0"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196201112660201"},{"key":"e_1_2_1_4_2","first-page":"225","article-title":"Endoscopic evaluation and therapy of periampullary adenoma","volume":"78","author":"Siegel JH","year":"1983","journal-title":"Am J Gastroenterol"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(76)90044-1"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1960.01300030139018"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810801)48:3<799::AID-CNCR2820480324>3.0.CO;2-Q"},{"key":"e_1_2_1_8_2","first-page":"476","article-title":"Villous tumors of the duodenum and jejunum","volume":"18","author":"Mir\u2010Madjlessi SH","year":"1973","journal-title":"Digestive Diseases"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-196411000-00011"},{"key":"e_1_2_1_10_2","first-page":"203","article-title":"Adenomas of the gallbladder and extrahepatic bile ducts","volume":"136","author":"Hulten J","year":"1970","journal-title":"Acta Chir Scand"},{"key":"e_1_2_1_11_2","first-page":"376","article-title":"Villous tumors of the duodenum","volume":"75","author":"Everett GD","year":"1981","journal-title":"Am J Gastroenterol"},{"key":"e_1_2_1_12_2","unstructured":"BergdahlL AnderssonA: Benign tumors of the papilla of Vater.Am SurgOct:563\u2013566 1980."},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1978.01370140070014"},{"key":"e_1_2_1_14_2","unstructured":"ChoctawWT BurbigeEJ McCandlessCM:Duodenal villous adenoma.
