[Embryological premises for the emergence of congenital obstruction of the duodenum in man].
There is no unity in views on the causes of the congenital "internal" duodenal obstruction occurring in the human being. The investigation makes it possible to conclude that the embryological premises for this pathology are: 1) death of epitheliocytes in the process of recanalization; 2) spiralization, resulting in narrowing the organ's flexure and in deformity of blood vessels. Morphogenesis of the duodenal papillae and of the intestinal villi contributes to stenosis of the intestinal canal. Spiralization and death of epitheliocytes--are normal processes of the embryonal organogenesis. But their abundance under influence of some external factors can stipulate disorders in the normal organogenesis.
