Duodenum is where food goes after having undergone appropriate processing in the stomach. Duodenostasis delayed motor Wrecker activity of the duodenum. The normal function of the way that passes the food after we’ve eaten, includes valve apparatus which is located a few key places: between the pharynx and esophagus, esophagus and stomach, stomach and duodenum, duodenum and small intestine, small and large intestine , bile and pancreatic Strait with the duodenum. When this valve apparatus works properly, then the ingested food can break down and absorb. The reason for its existence is that in each section of the digestive tract food is subjected to a treatment under the action of various enzymes, different pH, different amount and quality of the microbial flora. Due to the valve apparatus moves the food in one direction only, i.e. it prevents reflux, and adjusts the rate of its travel.
When a function in the human body is impaired, the body tries to compensate by compensatory and adaptive changes. This happens if impaired patency of the duodenum. The compensation results in enhanced peristalsis, hypertrophy and dilatation of the part of the muscle layer in the wall of the duodenum, increased pressure in the cavity of the casing. Subsequently, if the cause of this obstruction is not removed, is obtained and anti-peristaltic regurgitation (back to contents in the upper gastrointestinal tract). Inside continuously increased pressure causes failure of the above placements valve apparatus. All this leads to inflammation, spasm and subsequent stenosis.
Duodenostasis classified according to different features. If we take into account the reasons that caused it, Duodenostasis is divided into congenital (with congenital abnormalities of the duodenum or other structures that are directly related to it) and acquired (compression outside the duodenum and inside – tumors, foreign bodies, etc).
According to the nature of the impaired motor function Wrecker is divided into mechanical (intra- and ekstraduodenalna compression vrodemi anomalies) and functional (disorder in normal function by the action of toxins, infections in the neighborhood, lymphadenitis, damage to the vagal nerve).
According to functional status or resistive force of the organization we have compensated phase Duodenostasis, subcompensated and decompensated stage. In a phase body is trying to overcome the obstacle that prevents the passage of food. This is done through hard Wrecker motor activity of the intestine. On the other hand side is increased interbowel pressure and slows the evacuation of the contents thereof.
In different seasons have fluctuation in atmospheric pressure, which also affects. This is the reason for the seasonality of certain diseases. The high pressure leads to valvular insufficiency and regurgitation (return) of duodenal contents towards the upper gastrointestinal tract – stomach, biliary and pancreatic Strait. Often this is a factor in many diseases in those parts of the digestive tract. So is characterized subkompensatornata phase. Many authors have shown clinically and experimentally that Duodenostasis is one of the reasons for cholecystitis. Falling duodenal contents and pancreatic enzymes in bile ducts, leading to destruction of the gallbladder.
Increased pressure and cause reflux to pancreatic inflammation – pancreatitis. Acute course of Duodenostasis is due to complete obstruction of the duodenum. This may be caused by tumors, foreign bodies, parasites, stenosis (narrowing) and others. Ileus (intestinal neprohodmost), driven by Duodenostasis takes place rapidly and with a picture of “high ileus.” Therapy in most cases is operational.
