In the United States, 10% to 15% of adults are affected by gallstones, and cholesterol gallstones are the most prevalent subtype. Risk factors for developing gallstone disease include female sex; older age; certain medications; and having type 2 diabetes mellitus, nonalcoholic fatty liver disease, obesity, rapid weight loss, or hemolytic anemia. Nearly 80% of gallstones are found incidentally and remain asymptomatic. When symptomatic, gallstone disease usually presents as sudden onset right upper quadrant or epigastric abdominal pain. Common complications of gallstones include cholecystitis, choledocholithiasis, gallstone pancreatitis, and ascending cholangitis. The Murphy sign is a specific physical examination finding for acute cholecystitis. Ultrasonography is the initial imaging choice for detecting gallstones and acute cholecystitis. A hepatobiliary iminodiacetic acid (HIDA) scan can be used to evaluate for cholecystitis in patients with negative or equivocal ultrasound findings. Magnetic resonance cholangiopancreatography (MRCP) is an accurate, noninvasive diagnostic test to identify choledocholithiasis, certain malignancies, and biliary obstruction. Nonsteroidal anti-inflammatory drugs are safe and effective in treating pain from acute cholecystitis and biliary colic. Laparoscopic cholecystectomy is the treatment of choice for most patients with biliary colic or acute cholecystitis. Ursodeoxycholic acid and chenodeoxycholic acid should not routinely be used to treat gallstone disease, but they can be used as a nonsurgical alternative for certain patients. Postcholecystectomy syndrome is a potential postoperative complication that presents with abdominal pain, bloating, and diarrhea. (Am Fam Physician. 2024;109(6):518-524.

Gallstones, or cholelithiasis, are highly prevalent, affecting an estimated 10% to 15% of U.S. adults.1,2 Approximately 80% of all gallstones are cholesterol gallstones, which form because of precipitation of cholesterol.1,3 Black pigment gallstones (10% to 15%) comprise calcium bilirubinate, formed from unconjugated bilirubin deposition, often secondary to chronic hemolysis.2,3 Brown pigment stones (5%) are usually associated with biliary infections.3 Evidence-based answers to common questions about gallstone disease are discussed in this article.
WHAT'S NEW ON THIS TOPIC

| Recent meta-analyses have shown that dipeptidyl-peptidase-4 inhibitors (odds ratio = 1.22) and glucagon-like peptide-1 receptor agonists (relative risk = 1.27) increase the risk of gallstone disease, with greater risk in patients with longer duration of use (longer than 26 weeks). |
| A 2016 Cochrane review showed that nonsteroidal anti-inflammatory drugs provide greater relief from biliary pain compared with placebo (number needed to treat = 3) and antispasmodics (number needed to treat = 3) and no difference in pain control compared with opiates. |
| A systematic review of patients who underwent cholecystectomy found that 13% developed postcholecystectomy diarrhea. |
