What Is Biliary Sludge?
Biliary sludge is the accumulation of microcrystals due to concentrated bile inside the gallbladder. Pregnancy, prolonged fasting, rapid weight loss, the post-bariatric period and certain medications are risk factors. Many patients are symptom-free; some present with gallstone-like attacks. This page summarises when sludge is observed and when surgery is considered.

Biliary sludge refers to microcrystal accumulation from concentrated bile. Asymptomatic patients are usually observed. Recurrent biliary colic, cholecystitis or pancreatitis brings surgery into the discussion based on symptoms, ultrasound findings and comorbidities.
Symptoms
- Usually asymptomatic
- Occasional colic-like attacks
- Nausea, bloating
- Rarely pancreatitis
Diagnosis
Ultrasound is the main test. Endoscopic ultrasound can give more sensitive information in unclear cases.
Treatment
Asymptomatic patients are usually observed. Recurrent attacks, cholecystitis or pancreatitis indicate surgery.
