Obstruction of the bile ducts, as a rule, is associated with their blockage by some kind of mechanical obstruction that prevents bile from the liver and gallbladder from entering the duodenum.

The cause of such blockage can be cholelithiasis, inflammation of the bile ducts, their narrowing (stricture), as well as the formation of tumors and scars in the lumen of the common bile duct. As a rule, it is these pathologies that cause obstruction of the biliary tract. The treatment of such diseases is carried out mainly by surgical methods - from endoscopic intervention to extended abdominal or laparoscopic surgery. Blockage of the bile duct, description, symptoms and treatment is the topic of today's article,

This very dangerous complication occurs after a number of different diseases of the digestive system, the most common of which is cholelithiasis, which is diagnosed in almost every fifth person. Women are much more susceptible to this disease than men.

With the development of this pathology, bile calculi are formed in the cavity of the bladder, which, in the course of their migration, can partially or completely block the lumens of the bile ducts, leading to their obstruction. Violation of normal bile flow is accompanied by the appearance of signs of obstructive jaundice, which is characterized by yellowing of the skin and eye sclera, as well as a strong pain syndrome. If the patient is not provided with qualified assistance in time, obstruction of the bile ducts can even lead to death.

It is worth noting that blockage of the bile ducts can be caused not only by a mechanical obstruction inside the bile duct (for example, a stone), but also by squeezing the duct from the outside.

The severity of the clinical picture of the disease depends on how much the lumen of the duct is blocked.

As a rule, the process of obstruction of the bile duct begins with its inflammation, as a result of which the mucous membrane of the bile ducts thickens, and the lumen narrows accordingly. When a bile calculus enters such an inflamed canal, it gets stuck, as a result of which the choledoch is partially or completely blocked. Bile, having no outlet, accumulates in the ducts and stretches their walls. Since hepatic bile first enters the gallbladder, if the cystic or common duct is obstructed, the walls of this organ also stretch, thereby exacerbating the course of cholecystitis. If this occurs against the background of cholelithiasis, then stones from the bladder cavity can begin to migrate into the cystic duct, causing its obstruction. The most dangerous complications of such a pathological process are dropsy or empyema of the gallbladder.

If bile is retained in the intrahepatic bile ducts, this can cause the destruction of liver cells (hepatocytes), as a result of which bilirubin and bile acids can enter the bloodstream, causing general intoxication of the whole organism. In addition, since bile is responsible for the breakdown and subsequent absorption of heavy lipids, its deficiency in the intestine leads to malabsorption of vitamins contained in fats (A, E, K and D). This leads to the development of hypoprothrombinemia, disruption of normal blood clotting and other manifestations of hypovitaminosis. If the stagnation of hepatic bile in its excretory tract continues long enough, this leads to serious damage to the hepatic parenchyma, against which liver failure develops.

Risk factors that increase the likelihood of bile duct obstruction include:

improper diet and diet;
obesity;
rapid weight loss;
injuries in the area of the right side of the abdominal cavity;
recent operations on the organs of the biliary and digestive system by the patient;
infectious lesions of the biliary organs;
weakened immunity.

Clinical picture of obstruction of the bile ducts

As a rule, pathology begins to manifest itself gradually.

Acute manifestations at an early stage are quite rare. As we said above, the onset of this process is usually associated with the development of inflammation or infection of the bile ducts. The patient begins to complain of fever, weight loss and paroxysmal pain on the right under the ribs. Perhaps the appearance of yellowness of the skin and eye sclera, accompanied by skin itching. Deficiency of bile acids in the intestine causes discoloration of feces, and an increase in direct bilirubin levels causes dark urine. If the obstruction of the bile ducts is partial, there is an alternation of discolored and normally colored feces.

The destruction of hepatocytes leads to disruption of all liver functions and the development of acute liver failure. The detoxification function of this organ is the very first to be disturbed, which is expressed by the following symptoms:

general weakness;
increased fatigue;
gradual dysfunction of other internal organs and systems of the body (brain, kidneys, heart, lungs).

The onset of this stage in the development of pathology is characterized by a very unfavorable prognosis.

The clinical picture of this pathology at an early stage of its development resembles the symptoms of cholecystitis or hepatic colic.

These external signs can lead to hospitalization of the patient.

The initial diagnosis is carried out using the procedure of ultrasound of the abdominal cavity. If gallstones are found, magnetic resonance cholangiography or computed tomography may be prescribed to search for them in the bile ducts.

In order to clarify the causes that cause obstructive jaundice, as well as to determine the location of the calculus and the degree of overlap of the lumen of the duct, the technique of percutaneous transhepatic cholangiography and the method of dynamic scintigraphy of the biliary system are used. These instrumental diagnostic methods make it possible to identify violations of the dynamics of bile and bile outflow.

The most informative method for diagnosing obstruction of the biliary tract is the method of retrograde cholangiopancreatography, which involves the simultaneous conduct of endoscopic and radiological examination of the bile ducts. If stones are found in the lumen of the bile duct, during such a procedure it is possible to extradite the calculus from the choledochus, and if a tumor compressing the duct is found, it is possible to take a biopsy from it.

If we talk about laboratory diagnostic methods, they allow us to identify the following:

in biochemical liver tests, an increased level of direct bilirubin, transaminases, alkaline phosphatase, blood lipase and amylase is found;
a general blood test determines leukocytosis, in which the leukoformula shifts to the left;
also, this analysis allows you to detect a decrease in the level of platelets and erythrocytes characteristic of this pathology;
the coprogram in this disease is characterized by a significant content of fat in the feces and the absence of bile acids.

Firstly, patients with such a diagnosis need to consult a gastroenterologist and a surgeon. After all the necessary examinations are carried out, the localization sites and the degree of obstruction are determined, the method of surgical therapy is selected. Conservative methods such pathologies are not treated.

If the patient is in serious condition, he is transferred to the intensive care unit, where urgent infusion, antibacterial and detoxification treatment is carried out. Before the patient's condition becomes stable, surgical intervention is very dangerous, and therefore preliminary methods for facilitating bile flow are used, namely:

If the use of these techniques does not alleviate the patient's condition, a more complex operation is performed for percutaneous transhepatic drainage of the biliary tract.

After normalization of the general condition of the patient, in the absence of contraindications, the use of endoscopic methods of surgical treatment is recommended. In the process of such an intervention, bougienage (expansion of the lumen) of the bile ducts is carried out (in cases of cicatricial stenosis and structures caused by tumors). It is possible to introduce special plastic or mesh tubular prostheses into the lumen of the canal to increase patency (procedure of endoscopic stenting of the common bile duct). If the calculus clogged the scar-narrowed papilla of the duodenum, then the procedure of endoscopic balloon dilatation of the sphincter of Oddi is used.

If endoscopic methods do not allow to remove obstacles to normal bile flow, advanced types of surgical intervention are used.

Choledochotomy involves the opening of the common bile duct, and therefore it is necessary to take measures to prevent subsequent leakage of bile into the abdominal cavity through postoperative sutures. For this purpose, external drainage of the bile ducts is carried out according to Kehr using a T-shaped tube.

After cholecystectomy (an operation to remove the gallbladder), external drainage is performed according to Halsted using a polyvinyl chloride catheter, which is inserted into the area of the cystic duct stump.

If obstruction of the biliary tract is not promptly treated using surgical techniques, this can lead to the development of sepsis, cirrhosis of the liver, bilirubin encephalopathy and liver failure (if the obstruction of the duct is complete - in acute form, if partial - in chronic).

If medical care is provided to a patient with this diagnosis on time, then in general the prognosis is favorable. Seriously complicates the treatment of such pathologies cancerous diseases of the choledochus.

Speaking from measures to prevent such diseases, they consist in the timely treatment of existing diseases of the biliary system and digestive organs, as well as in observing the correct diet and diet and in a healthy lifestyle.

Blockage of the bile ducts is a mechanical obstacle that occurs in the path of the flow of bile entering the duodenum to organize a stable process of digestion and breakdown of fatty acids. In most cases, it develops against the background of inflammatory diseases of the gallbladder or as a result of the formation of stones of various structure, size and nature of origin in it. The symptoms of this disease are almost always acute, and the patient admitted to the hospital complains of severe pain in the right hypochondrium. Treatment of bile obstruction is surgical in nature and is aimed at restoring the lumen of the bile duct, removing foreign objects that block the normal functioning of this organ of the digestive tract.

It will not be difficult for an experienced gastroenterologist to suspect, only by external signs, that the patient has clogged channels through which bile should circulate.

The symptoms of the disease first develop gradually, and then acquire a bright and specific manifestation, which is expressed in the following pathological sensations on the part of the patient:

In addition to this, the patient complains of loss of appetite, nausea, general physical weakness, periodic vomiting, and upset stool.

If the duct is only partially blocked, then in this case the symptoms of the disease disappear from time to time, but after 1-2 days they return again.

This suggests that the body itself is trying to unblock the path for a stable outflow of bile, but despite all attempts, the negative influence of the factor still remains, which does not allow the digestive secret to circulate freely and enter the organs of the gastrointestinal tract.

Causes of obstruction of the biliary tract

Obstruction of the bile ducts can occur due to static compression of their walls from the outside, on the sides, or from the inside of the duct itself. The presence of these circumstances has a direct impact on the clinical picture of the manifestation of the disease. In addition, there are a number of pathologies of this part of the human digestive system that disrupt the work of both the gallbladder itself and its ducts. Based on this, the following causes of canal obstruction are distinguished:

In medical practice, there are clinical cases when patients with symptoms of obstruction of the biliary tract after an injury to the abdominal cavity were admitted to the inpatient department of the hospital. This is a strong blow to the right side of the abdomen, or a fall from a great height, which provoked swelling of the mucous membranes and epithelial tissues located in a circle.

To what doctor to go and what inspections to pass or take place?

It all depends on where exactly the person lives, faced with signs of blockage of the biliary tract. It is recommended to make an appointment with a gastroenterologist or hepatologist. If, for one reason or another, there are no specialists of the specified profile in the polyclinic, as a staff unit, then in this case it is necessary to visit a general practitioner. This is a family doctor who has a large amount of knowledge and is able to conduct an initial examination of the patient, palpate the abdominal cavity and establish that the localization of the pathology is concentrated on the right side in the hypochondrium.

After that, the patient is assigned to pass an additional list of tests and the passage of diagnostic measures, which consists in the following actions:

blood from a finger for her clinical trial;
morning urine on an empty stomach;
Ultrasound diagnostics of the abdominal cavity with a particularly thorough study of the structure of the tissues of the liver, gallbladder, its ducts and communication routes with neighboring organs of the gastrointestinal tract;
venous blood for its biochemical analysis;
feces to examine feces for the presence or absence of bilirubin, bile particles and other enzymes, the synthesis of which is closely related to the functional activity of the gallbladder.

In especially complicated cases, it may be necessary to conduct an MRI diagnostic if all of the above methods have not brought the desired result and the attending physician still doubts the diagnosis.

In oncological pathologies, a biopsy is used with a histological analysis of selected tissue samples in order to establish a malignant or benign etiology of the tumor body.

Treatment of clogged bile ducts

Therapy of the disease largely depends on the clinical picture of its manifestation and the symptoms that are present in a particular patient. The following treatment methods are most often used.

Surgical removal of stones

It can be carried out using endoscopic equipment in order to minimize trauma to the patient's body, or by extensive surgical intervention with a strip incision and opening of the choledochus (choledochomy). The patient at this time is in the operating room under general anesthesia.

Bougienage

The therapeutic method is intended to expand the lumen of the bile ducts, if they have narrowed after suffering a severe inflammatory process, associated with the formation of multiple scars on the inside of the canal walls. Special medical equipment and endoscopic instruments are used.

Stenting of the common bile duct

This is a minimally invasive operation, the principle of which is that a special expansion stent is inserted into the cavity of the common choledochus. Its functional purpose is to relieve painful symptoms, restore bile patency and prevent the recurrence of the disease in the future.

Transrenal drainage

It is used only in particularly difficult clinical cases, when blockage of the biliary tract caused complications and a liver disorder occurred, and the patient himself is threatened with the onset of liver failure. In order to avoid this kind of negative consequences, forced bile drainage is installed.

Anti-inflammatory and antibacterial drugs are actively used in combination with surgical treatment. Especially if the narrowing of the lumen of the bile duct has arisen due to the ingress of pathogenic microflora into it.

Prevention

In order to never encounter blockage of the choledochus, or to minimize the risk of the onset of the disease, you should follow the simple rules of prevention daily, which consist of the following actions:

eating only biologically healthy foods;
complete abstinence from alcohol, smoking and drug use;
maintaining an active lifestyle, playing sports;
balanced and moderate consumption of foods containing fiber, fats of vegetable and animal origin, meat and dishes prepared on their basis;
fried, smoked, pickled, highly fatty foods should be completely excluded from the menu;
periodically take (1 course in 6 months) drugs on a natural basis, which stimulate the outflow of bile, do not allow it to stagnate in the bladder and ducts with further transformation into stones.

It is very important to treat infectious and viral diseases of the liver in a timely manner, not to translate them into a chronic condition, which can at any time go into an exacerbation stage and negatively affect the functioning of the gallbladder. People who pay attention to these preventive measures never have problems with this part of the digestive system and always have excellent appetite, but do not gain weight.

Biliary obstruction is a blockage in the bile ducts that carry bile from the liver to the gallbladder and small intestine.

Causes

It is a fluid produced in the liver. It contains cholesterol, bile salts, and metabolic products such as bilirubin. Bile salts help the body break down fats. From the liver through the bile ducts, bile enters the gallbladder, where it accumulates. After eating, bile enters the small intestine.

When the bile ducts are blocked, bile accumulates in the liver, and due to an increase in the level of bilirubin in the blood, jaundice develops (yellow color of the skin).

Risk factors for the disease include:

History of gallstones, chronic pancreatitis, or pancreatic cancer
Abdominal injury
Recent surgery on the biliary tract
Previous history of biliary cancer (eg, bile duct cancer)

In people with weakened immune systems, obstruction can also be caused by infection.

Symptoms

Pain in the upper right corner of the abdomen
Darkening of the urine
(icteric discoloration of the skin)
Nausea and vomiting
Discoloration of feces

Diagnostics

The doctor or nurse will examine you and your abdomen.

The following blood test results may indicate a possible obstruction:

Increasing bilirubin levels
Increased alkaline phosphatase
Elevated liver enzymes

To identify possible obstruction of the bile ducts, the following tests may be prescribed:

Ultrasound of the abdominal organs
abdominal organs
Endoscopic retrograde cholangiopancreatography (ERCP)
Percutaneous transhepatic cholangiography (PTCG)
Magnetic resonance cholangiopancreatography (MRCP)

Bile duct obstruction can also affect the results of the following tests:

The content of amylase in the blood
Radionuclide scanning of the gallbladder
The content of lipase in the blood
Prothrombin time (PT)
The content of bilirubin in the urine

Treatment

The goal of treatment is to eliminate the obstruction. Stones can be removed through an endoscope during an ERCP.

In some cases, surgery may be required to remove the obstruction. If the blockage is caused by gallstones, they are usually removed. If you suspect an infection, your doctor may prescribe antibiotics for you.

If the obstruction is due to cancer, the duct may be dilated. This procedure is called endoscopic or percutaneous (performed through the skin next to the liver) dilation. A special tube may be placed in the duct to provide drainage.

Forecast

If the obstruction is not relieved, it can lead to life-threatening infections and a dangerous buildup of bilirubin.

Prolonged obstruction can lead to chronic liver disease. Most obstructions can be corrected with endoscopy or surgery. With a blockage caused by cancer, the prognosis is usually worse.

Possible Complications

If left untreated, complications such as infections, sepsis, and liver disease, such as biliary cirrhosis, can occur.

When to see a doctor

Call your doctor if you notice a change in the color of your urine and stool, or if you develop jaundice.

Prevention

Be aware of your risk factors, so it will be easier for you to get timely diagnosis and treatment in case of blockage of the bile duct. There are no methods to prevent obstruction of the biliary tract.

- a mechanical obstacle to the movement of bile from the liver and gallbladder into the duodenum. It develops against the background of cholelithiasis, tumor and inflammatory diseases of the biliary tract, strictures and scars of the common bile duct. Symptoms of the pathology are pain in the right hypochondrium, jaundice, acholic feces and dark urine, a significant increase in the level of bilirubin in the blood. The diagnosis is made on the basis of studies of biochemical blood samples, ERCP, ultrasound, MRI and CT of the abdominal organs. Treatment is usually surgical - endoscopic, laparoscopic or advanced surgery is possible.

General information

Blockage of the bile ducts is a dangerous complication of various diseases of the digestive system, which leads to the development of obstructive jaundice. The most common cause of bile duct blockage is gallstone disease, affecting up to 20% of people. According to the observations of specialists in the field of gastroenterology and abdominal surgery, women suffer from gallstone disease three times more often than men.

Difficulty in the outflow of bile from the liver and gallbladder is accompanied by the gradual development of the clinical picture of subhepatic (mechanical) jaundice. Acute blockage of the biliary tract can develop immediately after an attack of biliary colic, but this is almost always preceded by symptoms of inflammation of the biliary tract. Untimely assistance to a patient with blockage of the bile ducts can lead to the development of liver failure and even death of the patient.

Causes

Both obstruction of the biliary tract from the inside and compression from the outside can cause obstruction of the biliary tract. A mechanical obstruction to the outflow of bile can be complete or partial, the brightness of clinical manifestations depends on the degree of obstruction. There are a number of diseases that can interfere with the passage of bile from the liver to the duodenum. Blockage of the ducts is possible if the patient has: stones and cysts of the bile ducts; cholangitis or cholecystitis; scars and strictures of the ducts.

The pathogenesis of blockage of the bile ducts is multicomponent, the inflammatory process in the biliary tract usually serves as the beginning. Inflammation leads to thickening of the mucosa, narrowing of the lumen of the ducts. If at this moment a calculus enters the ducts, it cannot leave the choledoch on its own and causes a complete or partial blockage of its lumen. Bile begins to accumulate in the bile ducts, causing them to expand. From the liver, bile can first enter the gallbladder, greatly stretching it and causing an exacerbation of the symptoms of cholecystitis.

If there are stones in the gallbladder, they can enter the cystic duct and block its lumen. In the absence of outflow of bile through the cystic duct, empyema or dropsy of the gallbladder may develop. An unfavorable prognostic sign for blockage of the biliary tract is the secretion of whitish mucus (white bile) from the mucous membrane of the choledochus - this indicates the beginning of irreversible changes in the bile ducts. The retention of bile in the intrahepatic ducts leads to the destruction of hepatocytes, the entry of bile acids and bilirubin into the bloodstream.

Active direct bilirubin, which is not bound to blood proteins, enters the blood, because of which it causes significant damage to the cells and tissues of the body. The bile acids found in bile facilitate the absorption and metabolism of fats in the body. If bile does not enter the intestine, the absorption of fat-soluble vitamins A, D, E, K is disrupted. Because of this, the patient develops hypoprothrombinemia, bleeding disorders, and other symptoms of hypovitaminosis. Further stagnation of bile in the intrahepatic pathways leads to significant damage to the liver parenchyma, the development of liver failure.

Symptoms

Symptoms of blockage of the bile ducts usually appear gradually, the acute onset is quite rare. Usually, the development of a clinic of biliary obstruction is preceded by an infection of the biliary tract. The patient complains of fever, weight loss, cramping pain in the right hypochondrium. The skin becomes icteric, the patient is worried about itching of the skin. The absence of bile acids in the intestine leads to discoloration of the feces, and increased excretion of direct bilirubin by the kidneys leads to the appearance of dark urine. With partial obstruction, alternation of discolored portions of feces with colored ones is possible.

Complications

Against the background of destruction of hepatocytes, all liver functions are disturbed, acute liver failure develops. First of all, the detoxification activity of the liver suffers, which is manifested by weakness, increased fatigue, a gradual disruption of the functioning of other organs and systems (lungs, heart, kidneys, brain). If the patient is not assisted before this stage of the disease, the prognosis is extremely unfavorable. In the absence of timely surgical treatment of pathology, the patient may develop sepsis, bilirubin encephalopathy, cirrhosis of the liver.

Diagnostics

The initial manifestations of blockage of the bile ducts resemble the symptoms of cholecystitis or biliary colic, with which the patient may be hospitalized in the gastroenterology department. Preliminary diagnosis is carried out using such a simple and safe method as ultrasonography of the pancreas and biliary tract. If stones of the biliary tract, expansion of the choledochus and intrahepatic bile ducts are found, MR-pancreatocholangiography, CT of the biliary tract may be required to clarify the diagnosis.

To clarify the cause of obstructive jaundice, the location of the calculus, the degree of blockage of the biliary tract, percutaneous transhepatic cholangiography, dynamic scintigraphy of the hepatobiliary system is performed. They allow you to detect a violation of the dynamics of bile, its outflow from the liver and gallbladder. The most informative diagnostic method is retrograde cholangiopancreatography. This technique includes simultaneous endoscopic and X-ray examination of the biliary tract. If stones are found in the lumen of the duct during this procedure, the stones can be extracted from the choledochus. In the presence of a tumor that compresses the bile duct, a biopsy is taken.

In biochemical samples of the liver, there is an increase in the level of direct bilirubin, alkaline phosphatase, transaminases, amylase and blood lipase. Prothrombin time is prolonged. In the general analysis of blood, leukocytosis with a shift of the leukoformula to the left, a decrease in the level of erythrocytes and platelets can be detected. A significant amount of fat is found in the coprogram, bile acids are absent.

Treatment of blockage of the bile ducts

All patients require consultation with an abdominal surgeon. After all the examinations, finding out the localization and degree of obstruction, the tactics of surgical treatment is determined. If the patient's condition is severe, it may be necessary to transfer him to the intensive care unit for antibacterial, infusion and detoxification therapy.

Before the patient's condition stabilizes, an extended operation can be dangerous, therefore, non-invasive techniques are used to facilitate the outflow of bile. These include extraction of bile duct calculi and nasobiliary drainage with RPCG (through a probe inserted above the site of bile duct narrowing), percutaneous puncture of the gallbladder, cholecystostomy and choledochostomy. If the patient's condition does not improve, a more complex intervention may be required: percutaneous transhepatic drainage of the bile ducts.

After the patient's condition returns to normal, the use of endoscopic treatment methods is recommended. During endoscopy, expansion (endoscopic bougienage) of the biliary tract is carried out with their cicatricial stenosis and tumor strictures, the introduction of a special plastic or mesh tube into the biliary tract to preserve their lumen (endoscopic stenting of the common bile duct). In case of obstruction of the cicatricial narrowed papilla of the duodenum with a calculus, endoscopic balloon dilatation of the sphincter of Oddi may be required.

If stones and other obstructions to the outflow of bile cannot be removed endoscopically, an extended operation is required. During such surgery, the choledochus is opened (choledochomy), so in the future it is necessary to prevent leakage of bile through the sutures of the bile duct into the abdominal cavity. For this, external drainage of the bile ducts is performed according to Ker (T-tube), and after cholecystectomy - external drainage of the bile ducts according to Halsted (polyvinyl chloride catheter inserted into the stump of the cystic duct).

Forecast and prevention

The prognosis for timely medical care is favorable. Significantly worsens the course of the disease and the results of treatment cancerous obstruction of the choledochus. Prevention consists in the treatment of chronic inflammatory diseases of the hepatobiliary system, cholelithiasis. It is recommended to maintain a healthy lifestyle, proper nutrition with the exception of fatty, fried and extractive foods.

It is very important to know what to do when the bile ducts are clogged, the symptoms and treatment of which disease should be considered, and what consequences of this condition are possible. What is duct blockage? This is the name of obstruction in the form of a mechanical obstacle that bile encounters during its movement, leaving the liver or gallbladder towards the duodenum.

Symptoms of the disease

According to medical statistics, about 20% of the studied people experience this phenomenon. And most of them are women.

May occur as a consequence of the following diseases:

cholelithiasis;
various tumors or inflammations associated with the liver or gallbladder;
strictures and scars in the common duct.

The main symptoms that indicate that there is a problem associated with the ducts include:

the occurrence of pain in the hypochondrium on the right;
manifestation of symptoms of jaundice;
there is acholic feces along with dark urine;
increases the level of bilirubin in the blood.

The diagnosis should be made only by a doctor on the basis of a biochemical blood test. In addition, ERCP, ultrasound, MRI and CT of the abdominal organs are required. If a problem is identified, surgical treatment should be performed.

Depending on the severity of the disease, it is possible to carry out endoscopic, laparoscopic treatment. In more advanced or severe cases, the question of an extended operation to eliminate the blockage is raised.

As a result of difficulties for the movement of bile, a disease called subhepatic jaundice can occur. Quite often, conduction problems can occur after bouts of colic, as well as when symptoms associated with the development of inflammation appear. In this case, it will be necessary to provide medical assistance to a patient suffering from blocked bile ducts as soon as possible.

Cholangitis symptoms and treatment

The main causes of the development of the disease

Caused by obstruction of the biliary tract, the problem is not only the formation of an internal blockage, but also as a consequence of external pressure. Doctors highlight a complete or partial mechanical obstruction to the outflow of bile. Moreover, its degree will depend on what clinical manifestations are observed at the moment.

It is already known that there are a number of diseases that can lead to impaired patency, as a result of which intrahepatic pain appears as a result of the absence or incomplete flow of bile from the liver into the duodenum.

Passage blockage may occur when the patient is diagnosed with:

Symptoms of the development of a disease associated with blockage of the bile ducts is a multicomponent process. Most often, it shows that an inflammatory process in the biliary tract has appeared and begins to develop. Moreover, the inflammation itself contributes to a significant thickening of the mucosa, which inevitably leads to a decrease in the lumen in the ducts themselves.

Naturally, the calculus that got into the passage simply gets stuck in it and cannot be washed out with bile. As a result, the common passage is blocked completely or partially. Bile begins to accumulate, expanding the passages. As a result, bile leaves the liver and enters the gallbladder, stretching it. Because of this, symptoms worsen and cholecystitis develops.

A scheme of such a situation is possible provided that the calculi occur in the gallbladder. In the process of life, they can get into the duct, blocking it completely or partially. As a consequence of this process, empyema or dropsy will develop. If the secretion of the mucosal choledochus of whitish mucus is detected, then this can be evidence not only of blockage, but also of the beginning of irreversible changes in the bile ducts themselves, which will inevitably affect the state of health.

As a result of obstruction of bile along its ducts, destruction of hepatocytes begins to develop. As a result, acids and their accompanying bilirubin can enter the bloodstream, and infection begins. Moreover, both the blood vessels themselves and the tissues of the organs are affected.

The lack of bile in the body also negatively affects the functioning of the body. After all, it is involved in the process of digestion, breaking down fats and vitamins, accelerating their absorption. As a result, a person has hypoprothrombinemia, which is a disease associated with blood clotting, hypovitaminosis.

If bile stasis occurs, then a significant violation of the liver parenchyma may occur, which means that a person is faced with liver failure.

How to check the gallbladder

Etiology factors

Obesity is one of the main risk factors for the occurrence and subsequent development of blockage in the bile ducts. Can provoke this process and rapid or sudden weight loss, as well as:

received injuries in the area of the right half of the abdominal cavity;
operations performed in the near past on the biliary tract, liver or gallbladder;
penetration of infections associated with the hepatobiliary system, pancreas, developing due to weakened immunity;
during the chronic stage of pancreatitis;
if there are stone formations in the gallbladder;
in advanced pancreatic cancer.

It is for this reason that doctors will need to know exactly all the symptoms of the disease and conduct a complete study. This is necessary to identify the cause and prescribe accurate treatment, including emergency surgery.

Therapy Methods

If during the study a blockage of the bile ducts was detected, then an additional consultation with a gastroenterologist or surgeon may be required. Only this allows not only to determine the severity of the disease, but also to prescribe treatment. Moreover, if a severe form of the disease is detected, the patient should be transferred to the intensive care unit, and an antibacterial, infusion and detoxification form of therapy should be carried out. This is due to the fact that before carrying out surgical treatment, it is required to stabilize the patient's condition in order to avoid the risk of complications or even death.

In order to facilitate the outflow of bile, it is necessary to use various non-invasive techniques. This may be the extraction of calculi of the bile ducts or nasobiliary drainage using a special probe, cholecystostomy and choledochostomy.

If the patient is in a satisfactory condition, or relief has come, then endoscopic treatment methods are used for treatment. At the same time, during endoscopy, all clogged ducts will be expanded, which is the introduction of a special plastic or mesh tube into the biliary tract. Thanks to it, it is possible to ensure that a sufficient width of the clearance is maintained. This procedure is called endoscopic stenting of the common bile duct. In some cases, endoscopic balloon dilatation of the so-called sphincter of Oddi is necessary.
