General x-ray symptoms of digestive diseases

Nearly every disease of the digestive system by x-ray looks for changes from the side clearance filled by contrast agent bodies. Undoubtedly, changes in topography and dynamic violations are of great diagnostic value, but the most important role is played by the change of form and size, which is manifested in a variety of reductions (narrowing) and increases (extensions) clearance.
In the study of x-ray symptoms of changes of the digestive system, special attention should be paid to the state of concernenti investigated organ. Contour sharpness is an important sign of a lack of deep organic changes, associated with the tumor and less with inflammatory processes.
Expansion and narrow clearance may be uniform or non-uniform, common and disabilities that may affect changes size and shape of the investigated organ.
In each case seems to be a very important decision of the question whether the narrowing spastic or organic. In such circumstances, the right solution can be achieved as a result of repeated observations or application of appropriate pharmacological effects. However, it should be remembered that the manifestation of spastic changes often depend on the availability of nearby organic process, which leads to a spasm of the examined organ.
The narrowing of the lumen can be caused sharp hyperplasia mucosa inflammatory or malignant changes, and also at significantly expressed oedema. In such cases, in the lumen of the investigated body are uneven, bumpy growth, often reaching large sizes. This excessive growth or swelling leads to a "minus shadows compared to the expected norm due to the "plus shadows arising from edema, inflammation hyperplasia or cancer growth. Created wrong and rounded clearance in contrast the mould of the body is called "filling defect" which in most cases is characterized by presence of a tumor.
The accumulation of fluid and gas in the adjacent organs, lymph node hyperplasia and increase parenchymatous organs can entail not only the offset, but the compression of the examined organ, creating in this way the narrowing of mechanical origin. The process of scarring in the adjacent organs can lead to the postponement of walls of this body and to narrowing his clearance.
The extension of the lumen usually occurs under the influence of a significant reduction in the tone of the body. These extensions can be shared and be called a deep change control system, and also on the grounds of secondary changes in tone due to the weakening of muscles in the persistent violations of permeability and evacuation formed because of scar or tumors, thus creating the so-called superstrategies expansion.
In most cases superstrategies extensions occur on the local soil, limited and organic narrowing. When scar narrowing the width of the lumen of the corresponding part of the digestive tube reaches a very large size, much larger than any extension on the grounds neurocologues cancer narrow clearance.
Local extensions of the lumen of digestive tube are limited protrusion of the wall, called diverticula and ulcerative niche, creating the effect of a plus of shadows", in relation to the expected norm in the destructive process that creates a "minus tissue filled this space by contrast agent.
The above separate rentgenograficheskie symptoms rarely occur in pure form. Mainly with organic lesions of the digestive tube have to deal with this or that combination of the contractions and expansions, often in direct proportion to one another.
Functional symptoms of digestive diseases are expressed in various forms of violations of tone and peristalsis and evacuation contrast mass.
The tone of radiologically characterized by the degree of raspravljati walls of each Department of the digestive tube under the influence of pressure coming contrast mass. Under normal tone contrast weight evenly stretches of the studied segment of the gastrointestinal tract to obtain the relevant anatomical form. Hypertension is accompanied by a sharply increased resistance of walls, resulting in a slowly unfolding, and the lumen of this segment of the gastrointestinal tract is somewhat diminished. Hypotension leads to a decrease of the resistance of the walls, resulting in contrast weight easily spreads wall, quickly fills the lumen, and he becomes more or less advanced.
Peristalsis radiographically evident in the form of a uniform, rhythmically emerging waves describing the actual motor activity of gastrointestinal tract and reflecting the contractile ability of its walls.
But rhythm peristalsis, has value and its amplitude. Depending on the appearance of each new reduction of the rhythm of peristalsis may be normal, fast and slow. Depth peristaltic waves characterizes its amplitude. The combination of rhythm and amplitude of peristalsis may fail at pathological conditions and thereby to Express the nature of the violations actually motor functions of the digestive tube. Mainly in violations of the nature of peristalsis reflect changes in innervation, which is essential for the determination of the disease in the process of determining the induced changes in a sick body and the surveillance of their variability under the influence of a particular type of therapeutic treatment. Absence of peristalsis always indicates the presence of organic amendments, and often one symptom is enough to determine any, especially tumor infiltration in its earliest manifestations.
Evacuation dysfunction are determined by quick emptying of this or that Department of the digestive tube and character advancement in the sense of uniformity or irregularity.
The tone and peristalsis and evacuation are connected in a specific interdependence and are influenced by regulating the nervous system. Under pathological conditions these violations reflect the state of the nervous system and, thus, give an opportunity to have an idea about relevant developments radiographically defined changes of the functional state of organs of digestion.
