title: [Mineralogy of calcium deposits observed on duodenal cannulae in dogs].
abstract: Spontaneous precipitation of deposits on duodenal cannulae were observed in laboratory dogs. X ray diffraction study demonstrated that apatite was always present, while other calcium salts, such as gypsum and brushite, were sometimes present. Moreover another, not yet identified, crystalline substance was also documented.
