title: Chronic nonspecific duodenitis (bulbitis).
abstract: "Bulbitis" was classified by fiberoptic endoscopy in: superficial, erosive and pseudopolypoid. Endoscopic diagnosis of "bulbitis" is reliable, as good agreement was obtained in 100 cases tabulated according to histological grading. Erosive "bulbitis" implies a severe histopathological compromise.
