Anyone knows where the liver is, about herroles in the physiology of a living organism. But where is the choledoch, what is it? This is not all know. An auxiliary organ of digestion is the gallbladder. The narrowest part of it (neck) passes into the cystic duct and merges with the hepatic. The ducts choledochus is formed by the common bile duct, or simply speaking, the choledoch.
It runs along the outer edge of the liver, betweenperitoneal sheets in the region of the hepatoduodenal ligament, falling down between the head of the pancreas and the duodenum (12 PCs). Then it passes from the inside, through the back wall of the 12PK and flows into the intestinal lumen in the area of the Vater papilla.
There are certain physiological standards andcholedoch. The norm is represented by the following indicators: its length should be 2–12 cm. The dependence of this characteristic on the place where the cystic duct flows is observed. If the hepatic duct is lengthened, the choledoch will be shorter. What does it mean? Only that the length of the duct is individual. The diameter changes from a larger indicator to a smaller one along the way. At the beginning it is 5-8 mm. Then there is a change in the lumen, and in the place of entry into the intestine, the duct narrows to 3 mm. Wall thickness ranges from 0.5 to 1.5 mm. In pathological conditions due to the proliferation of connective tissue, the choledoch may thicken to 3-4 mm.
The common bile duct consists of 4 sections.
Существует целый ряд патологических изменений common bile duct. One of them is the dilation of the choledochus. Dilatation from Latin dilatation - expansion of the ductal lumen. Occurs due to mechanical contraction of the lower part of the organ.
Causes of dilatation:
Возникает ряд закономерных вопросов.How does choledoch change? What does this entail? In such cases, a number of clinical studies are prescribed to establish the cause of changes in the lumen and to choose the method of further treatment.
The most common and reliable methodliver examination is ultrasound. Modern ultrasound machines provide a clear picture of the state of the hepatic ducts. Unfortunately, small stones in the common duct are often not visualized with ultrasound. In such cases, it is necessary to resort to other diagnostic methods in order to investigate the entire choledoch. What are these methods?
These methods make it possible to establish the cause of obstruction of the common duct more accurately and in hard-to-reach places.
It is necessary to note the importance of the general and biochemical analysis of blood. These studies suggest the presence of inflammatory processes.
Changes in the common bile duct indicateabout the existence of pathological processes in the liver and gallbladder. What causes liver disease? The root cause is always a way of life and food, frequent use of alcohol, smoking. The love of fatty, fried foods also plays a role, as does the uncontrolled, unjustified use of medicines. Sometimes problems are due to the innate characteristics of a person. Sooner or later, this leads to inflammation, the formation of stones. The blockage and expansion of the choledoch begins. If the pathological processes are asymptomatic, the situation is aggravated and leads to serious consequences, up to pancreatic necrosis.
Treatment should be comprehensive.If the main reason is the presence of concrements in the common bile duct, the focus of treatment often comes down to surgery. The possibilities of modern medicine allow the use of methods of reconstruction of damage to the common bile duct, less traumatic surgical interventions.
With parasitic and inflammatory diseasesantibiotic therapy and duodenal intubation aimed at relieving the common bile duct from stagnation are conducted. The most effective method is prevention. Healthy food, reasonable physical activity, timely preventive medical examination will help you keep fit for many years.
