In those who are having gallbladder attacks, surgery to remove the gallbladder is typically recommended. This can be carried out either through several small incisions or through a single larger incision, usually under general anesthesia. In rare cases when surgery is not possible, medication can be used to dissolve the stones or lithotripsy can be used to break them down.In developed countries, 10–15% of adults experience gallstones. Gallbladder and biliary-related diseases occurred in about 104 million people (1.6% of people) in 2013 and resulted in 106,000 deaths. Gallstones are more common among women than men and occur more commonly after the age of 40. Gallstones occur more frequently among certain ethnic groups than others. For example, 48% of Native Americans experience gallstones, whereas gallstone rates in many parts of Africa are as low as 3%. Once the gallbladder is removed, outcomes are generally positive. Definition
Gallstone disease refers to the condition where gallstones are either in the gallbladder or common bile duct. The presence of stones in the gallbladder is referred to as cholelithiasis, from the Greek chol- (bile) + lith- (stone) + -iasis (process). The presence of gallstones in the common bile duct is called choledocholithiasis, from the Greek chol- (bile) + docho- (duct) + lith- (stone) + iasis- (process). Choledocholithiasis is frequently associated with obstruction of the bile ducts, which can lead to cholangitis, from the Greek: chol- (bile) + ang- (vessel) + itis- (inflammation), a serious infection of the bile ducts.
A gallstone is a stone formed within the gallbladder from precipitated bile components. The term cholelithiasis may refer to the presence of gallstones or to any disease caused by gallstones, and choledocholithiasis refers to the presence of migrated gallstones within bile ducts. Most people with gallstones (about 80%) are asymptomatic. However, when a gallstone obstructs the bile duct and causes acute cholestasis, a reflexive smooth muscle spasm often occurs, resulting in an intense cramp-like visceral pain in the right upper part of the abdomen known as a biliary colic (or "gallbladder attack"). This happens in 1–4% of those with gallstones each year. Complications from gallstones may include inflammation of the gallbladder (cholecystitis), inflammation of the pancreas (pancreatitis), obstructive jaundice, and infection in bile ducts (cholangitis). Symptoms of these complications may include pain that lasts longer than five hours, fever, yellowish skin, vomiting, dark urine, and pale stools.Risk factors for gallstones include birth control pills, pregnancy, a family history of gallstones, obesity, diabetes, liver disease, or rapid weight loss. The bile components that form gallstones include cholesterol, bile salts, and bilirubin. Gallstones formed mainly from cholesterol are termed cholesterol stones, and those formed mainly from bilirubin are termed pigment stones. Gallstones may be suspected based on symptoms. Diagnosis is then typically confirmed by ultrasound. Complications may be detected using blood tests.The risk of gallstones may be decreased by maintaining a healthy weight with exercise and a healthy diet. If there are no symptoms, treatment is usually not needed.
