Hardened crystal deposits formed from bile pigments, cholesterol, and calcium salts found in the bile duct (choledocholithiasis) or gallbladder (cholecystolithiasis). Commonly called gallstones, they are characterized by severe right upper quadrant abdominal pain or epigastric pain due to transient obstruction of the biliary tract. Other symptoms include nausea, vomiting, hyperbilirubinemia, and elevated alkaline phosphatase and gamma-glutamyl transpeptidase. Gallstones most typically occur in females in the fourth decade of life. They are increased during pregnancy, although they are relatively common and can occur in patients of all ages and across many demographics.
Treatment depends on size, location, and symptoms. Gallstones may end up in the duodenum or pylorus, which may result in gastric outlet obstruction (Bouveret syndrome). Common treatments are stone removal by endoscopic retrograde cholangiopancreatography, sphincterotomy, biliary stenting, and cholecystectomy. Goals of therapy are to prevent recurrent episodes of biliary colic and lower the risk of developing choledocholithiasis, cholangitis, and gallstone pancreatitis.

Biliary calculus is commonly known as gallstones. Gallstones are hard, crystal-like particles formed from bile fluids, cholesterol, and calcium. They can form in the gallbladder or bile duct.
Biliary calculus may not have any symptoms, or it may create intense pain. There may be other symptoms. Biliary colic (gallbladder attack) refers to severe pain caused by bile duct blockage.
Who’s At Risk
The exact cause of gallstones is uncertain. Many factors can contribute to their formation. Anyone can develop gallstones, but those most at risk are women over age 40. Gallstone formation may also run in the family. Other risk factors include:
Taking certain medications (such as birth control pills)
Some diseases (diabetes, sickle cell, cirrhosis)
Additionally, people who fast to lose weight quickly, or who have had weight-loss surgery, have a greater chance of developing gallstones.
Signs & Symptoms
Many people with gallstones have no symptoms. However, you may have right upper abdominal pain (near the stomach), nausea, and vomiting. You may even experience pain in the right shoulder or back.
Maintaining a healthy weight, increasing physical activity, and enjoying a healthy diet can help prevent gallstones and their complications.
Rapid weight loss should be avoided as it may increase your chances of getting gallstones. A healthy lifestyle can also help prevent recurrence of gallstones.
When to Seek Medical Care
If you have symptoms of gallstones such as severe abdominal or epigastric pain (near stomach), nausea, and vomiting, contact your health care provider.
If you develop symptoms of gallstone complications such as yellowish skin and eyes or unrelenting severe abdominal pain, get medical help immediately.
