@entity9317 produced by @entity461 occurred in 4.5% of the @entity1 hospitalized in our service. Often was associated with duodenal or gastric peptic ulcer, @entity357 and with some other @entity4801 ; particularly with ambiasis. Forty four @entity1 were studied in whom the only cause to demonstrate or explain their symptomatology was the presence of @entity461 in the duodenum. The complaints disappeared after the administration of specific treatment. The clinical manifestations remained an atypic @entity1066 without defined rhythm or periodicity; however, @entity338 are frequently present. The physical exploration does not help to the diagnosis. Gastric acidity is normal. X-ray studies demonstrate irregular mucosa of the stomach and duodenum and some spastic waves. Duodenoscopy allows to watch inflammatory changes of the duodenal mucosa and rules out peptic ulcer. The diagnosis is confirmed by the demonstration of the parasite, present in the fluid aspirated from the duodenum during the endoscopy.
