All changes that occur in the small intestine because of disorders of the state of tone and mobility impairments as a result of the change from the small intestine, and reflex
violations in various diseases not only gastrointestinal sphere, but also other organs can be United under the common title dyskinesias.
Largest group comprises dyskinesia, which arise under the impact of the changes taking place outside of the intestine, and can accompany many diseases in which there are disorders of the nervous system, hormonal sphere, vitamin a deficiency and some infectious diseases. However, there can be interagency reasons dyskinesias.
Depending on the nature of disorders of the locomotor activity of small intestine dyskinesia can be divided into the following main types:
1. Hypermotor dyskinesia. These include disorders that are associated with a sharp increase in motor function of the entire small intestine in General and individual, limited parts of it (Fig. 107). In most cases hypermotor dyskinesia accompanied hypertensive state of the small intestine. In such cases, psoriasis can be called gipermotorika-hypertensive.

Radiograph after 1 hour, 31 minutes after taking barium suspension: completed an extensive area of the colon.

2. Geometrie dyskinesia. This group is characterised by a marked weakening of motor function. Geometrie dyskinesia may be accompanied spastic phenomena and coordination disorders tone where mostly hypotonic conditions (Fig. 108). This leads to uneven distribution of the contrast medium and uneven width ground clearance.

Radiograph in 4 hours after administration of barium suspension: the uneven distribution of contrast in the course of the small intestine, spastic breaks, the delay in filling the colon.

When hypomotor dyskinesia, especially those that are accompanied hypotonic phenomena can take place disorders hydrodynamic balance submucosal layer. In such cases, you long to see the swollen folds with smazannost usual pattern of relief mucosa of the small intestine.
3. Mixed dyskinesia. This group includes such changes, in which there is a combination of various factors movement disorders and disorders of tone.
Expressed manifestations dyskinetic disturbances in the form of hypermotor dyskinesias are of particular importance to decrypt intercepted diseases associated with malnutrition. In particular, finds its explanation in the x-ray picture of the condition of the small intestine emaciation people with increased nervous irritability,- have found hypermotor dyskinesia. Almost as a rule, are able to state the same thing with different levels of tireotoxicoza, especially in graves ' disease. Naturally, with a sharp acceleration of moving food through the small intestine, it turns into a thick, without enough cleavage to be sufficiently internalized. Thus, there is endogenous starvation, the cause of which may be identified with radiological examination of the small intestine. Endogenous starvation can be explained and some vitamin deficiency, under some conditions dependent on the rapid movement of food through the small intestine, while others - from slow-motion, combined with swelling of the mucous membrane.
Often dyskinesia accompanied coordination disorders tone, as expressed in the alternation of hypertension and hypotension in different parts of the small intestine.
