PURPOSE: To revise literature data about @entity420 comparing to our results. METHODS: Six @entity1 with this kind of @entity5 , excluding periampullary lesions, were treated from 1991 to 1999 in the Department of Surgery, Santa @entity13389 of S  o Paulo Medical School. Five of them were males in theirs fifties. The commonest signs and symptoms were those of @entity344 and @entity353 . All @entity1 were evaluated by duodenoscopy. Ultrasonography and CT scans played an important role with regard to preoperative staging. Three @entity1 underwent a segmental resection and the others were submitted to a palliative duodenal bypass. RESULTS: Post-operative hospitalization varied from 5 to 9 days (7,3 days average). The operative mortality was 16.6% (one @entity1 ). @entity1 were not submitted to chemo or radiotherapy. Follow-up has been done. @entity1 with curative resection were free from recurrence. Two @entity1 submitted to palliative operations were lost to follow-up. CONCLUSION: Rarity of duodenum @entity189 and few @entity1 in the literature did not permit conclusions.
