These treatments are not widely available and are performed by experienced gastroenterologists with high volumes in these procedures. Gallstones and bile duct stones also known as choledocholithiasis are the same, just located in two different areas of the body. Stones may pass spontaneously out of the bile duct on their own. However, when a stone gets stuck in the bile duct, medical intervention is necessary, otherwise inflammation, bacterial infection, and even severe organ damage can occur.
Often there are no symptoms for bile duct stones until a stone causes a blockage in the bile duct. Then symptoms can include:. These microscopic crystals accumulate in the gallbladder, where they clump and grow into gallstones. Other types of gallstones form in the same way, but the solid particles are calcium compounds or bilirubin the main pigment in bile.
Stones composed of bilirubin, called pigment stones, are either black forming in the gallbladder or brown forming in the bile ducts. Black pigment stones are more likely to develop in people who have alcohol-related liver disease Alcohol-Related Liver Disease Alcohol-related liver disease is liver damage caused by drinking too much alcohol for a long time. In general, the amount of alcohol consumed how much, how often, and for how long determines Brown pigment stones can form when the gallbladder or bile ducts are inflamed or infected or when the bile ducts are narrowed.
The stones may stay in the gallbladder or pass into bile ducts. Stones can block the cystic duct, common bile duct, or ampulla of Vater where the common bile duct and pancreatic duct join. Most cholesterol stones in the bile ducts come from the gallbladder. Any narrowing stricture of the bile ducts can lead to a blockage or slow bile flow. Bacterial infections can develop when bile flow is slowed or blocked.
Sometimes microscopic particles of cholesterol, calcium compounds, bilirubin, and other materials accumulate but do not form stones. This material is called biliary sludge. Sludge develops when bile remains in the gallbladder too long, as it does during pregnancy. Gallbladder sludge usually disappears when its cause resolves, for example, when pregnancy ends.
However, sludge can evolve into gallstones or pass into the biliary tract and block the ducts. Gallstones may cause pain. Pain develops when the stones pass from the gallbladder into the cystic duct, common bile duct, or ampulla of Vater and block the duct. Then the gallbladder swells, causing pain called biliary colic. The pain is felt in the upper abdomen, usually on the right side under the ribs.
Sometimes the location is hard to pinpoint, particularly for people with diabetes and older people. The pain typically increases in intensity over 15 minutes to an hour and remains steady for up to 12 hours. The pain is usually severe enough to send people to the emergency department for relief. Once the pain begins to resolve, it does so over 30 to 90 minutes, leaving a dull ache.
People often feel nauseated and vomit. Eating a heavy meal can trigger biliary colic whether people eat fatty foods or not. Gallstones do not cause belching or bloating. Nausea occurs only when biliary colic occurs. Between episodes, people feel well. If the blockage persists, the gallbladder becomes inflamed a condition called acute cholecystitis Symptoms Gallstones are collections of solid material predominantly crystals of cholesterol in the gallbladder.
The liver can secrete too much cholesterol, which is carried with bile to the gallbladder When the gallbladder is inflamed, bacteria flourish, and infection may develop.
The inflammation usually causes fever. Blockage of the common bile duct or the ampulla of Vater is more serious than blockage of the cystic duct. Blockage of a bile duct can cause the ducts to widen dilate. It can also cause fever, chills, and jaundice Jaundice in Adults In jaundice, the skin and whites of the eyes look yellow.
Jaundice occurs when there is too much bilirubin a yellow pigment in the blood—a condition called hyperbilirubinemia.

Bacteria can spread to the bloodstream and cause serious infections elsewhere in the body sepsis Sepsis and Septic Shock Sepsis is a serious bodywide response to bacteremia or another infection plus malfunction or failure of an essential system in the body.
Septic shock is life-threatening low blood pressure Also, pockets of pus abscesses Symptoms An abscess is a pocket of pus, usually caused by a bacterial infection. Most people have constant abdominal pain and a fever. Computed tomography or another imaging test can distinguish an abscess Stones that block the ampulla of Vater also can block the pancreatic duct, causing inflammation of the pancreas pancreatitis Overview of Pancreatitis Pancreatitis is inflammation of the pancreas.
The pancreas is a leaf-shaped organ about 5 inches about 13 centimeters long. It is surrounded by the lower edge of the stomach and the first Inflammation of the gallbladder caused by gallstones can erode the gallbladder wall, sometimes resulting in a hole perforation.
Perforation results in leakage of the gallbladder contents throughout the abdominal cavity, causing severe inflammation peritonitis. A large gallstone that enters the small intestine can cause intestinal blockage, called a gallstone ileus. This rare complication is more likely to occur in older people. Doctors suspect gallstones in people with the characteristic pain in the upper abdomen caused by a swollen gallbladder.
These small stones are often developed when there is an excess of cholesterol in the body. Researchers at the University of Bonn in Germany found that this can also be hereditary. Liver stones are essentially the same as gallstones and the pain is often mistaken for gallstone pain.
The only difference is that liver stones are located in the liver rather than the gallbladder. What causes liver stones? As mentioned before, the cause of liver stones is often from excess cholesterol, but they can also be formed for example, if your bile contains too much bilirubin. Chemically, liver stones and gallstones are the same, they are both formed by bile or gall which is produced by the liver and aids in digestions of fats in the small intestine. The most common place for gallstones to form is in the gallbladder because bile is concentrated more so than in the liver itself.
Gallstones can form in the liver when the gallbladder has been removed or due to other circumstances. There are often no symptoms with gallstones in the liver, however, if you do experience symptoms they may manifest as the following:. If your doctor suspects that you may have liver stones then they may suggest an ultrasound or a liver function test to make a diagnosis. A liver ultrasound only takes around 30 minutes and is completely non-invasive.
