As in the stomach, duodenal bulb can develop various degrees of inflammatory changes, with marked expansion and swelling folds, sometimes accompanied by considerable strain relief mucous bulb (Fig. 100). Folds, which in normal bulbs have longitudinal direction and width not exceeding 2 mm, at the inflammatory process look like a stupid, coarse pripuhanie mucous membrane, reaches a very large size (up to the width of a finger on Prevot u. Lassrich, 1959). In addition, folds sometimes lose their elasticity and become the transverse direction. Such swelling folds spread to more distant from the bulbs departments of the duodenum. The inflammatory process may be limited to bulb, but in most cases, duodenitis associated with pathology of the output section of the stomach. However, there are some condition of the mucous membrane of the bulbs that are associated with the exacerbation of the ulcer duodenum, and due to the swelling of the mucous becomes possible to detect ulcerative niches. In such cases, the diagnosis is determined with the help of anti training pyramidon-adrenaline mix.
With frequent duodenitis onion usually not deformed, and tight filling it may be no morphological manifestations, but also accelerated promotion contrast suspended on it. Only if compression is possible to see the picture changed swollen mucosa, and repeat the same forms of the inflammatory process, as gastritis.
