From the Guidelines
The treatment for gallbladder sludge typically begins with watchful waiting as many cases resolve spontaneously. For symptomatic cases, ursodeoxycholic acid (ursodiol) at doses of 8-10 mg/kg/day divided into two doses for 3-6 months may help dissolve the sludge by decreasing cholesterol saturation in bile 1. Dietary modifications are important, including reducing fat intake, maintaining a healthy weight, and eating regular meals.
- Key considerations for treatment include:
- The size and composition of the gallstones
- The patient's overall health and risk factors for surgery
- The presence of symptoms such as biliary colic, acute cholecystitis, or pancreatitis
- For persistent symptoms, cholecystectomy (surgical removal of the gallbladder) may be recommended, typically performed laparoscopically with a short recovery period of 1-2 weeks 1. This surgery is considered when sludge causes recurrent biliary colic, acute cholecystitis, or pancreatitis.
- Treatment is necessary because gallbladder sludge can progress to gallstone formation or cause complications like inflammation, infection, or blockage of bile ducts. Patients should seek immediate medical attention for severe abdominal pain, fever, jaundice, or persistent vomiting, as these may indicate complications requiring urgent intervention 1.

Ursodeoxycholic Acid (Ursodiol)
The treatment for gallbladder sludge is Ursodeoxycholic Acid (Ursodiol), which is administered orally (PO) 2.
From the Research
Treatment Options for Gallbladder Sludge
- The treatment for gallbladder sludge can vary depending on the patient's symptoms and the presence of any complications 3, 4.
- For asymptomatic patients, a wait-and-see approach may be taken, as the sludge may resolve on its own 4.
- For patients who experience biliary-type pain, cholecystitis, cholangitis, or pancreatitis, treatment options include:
- Cholecystectomy (surgical removal of the gallbladder) for patients who can tolerate surgery 4, 5.
- Endoscopic sphincterotomy to prevent further episodes of cholangitis and pancreatitis in patients who are not operative candidates 4.
- Medical therapy with ursodeoxycholic acid to prevent sludge formation and recurrent acute pancreatitis 3, 4, 5.
- Ursodeoxycholic acid has been shown to be effective in dissolving gallstones and preventing sludge formation in some patients, but its effectiveness can vary depending on the composition of the stones and the patient's underlying condition 3, 6.
Effectiveness of Ursodeoxycholic Acid
- A study published in 1994 found that ursodeoxycholic acid was effective in dissolving gallstones and preventing sludge formation in patients with persistent biliary sludge, with a complete dissolution rate of 100% in patients with persistent biliary sludge 3.
- However, another study published in 1993 found that ursodeoxycholic acid was not effective in dissolving radiolucent gallstones in patients with cystic fibrosis, suggesting that the effectiveness of the treatment may depend on the underlying condition and the composition of the stones 6.
Clinical Importance of Biliary Sludge
- Biliary sludge can cause a range of complications, including cholelithiasis, cholecystitis, choledocholithiasis, and pancreatitis 4, 7.
- A study published in 2016 found that 25% of patients with biliary sludge developed a pancreaticobiliary complication over a mean follow-up period of 21 months, highlighting the potential clinical importance of biliary sludge 7.
