What is Biliary sludge and explain in detail?
Biliary sludge refers to a viscous mixture of small particles derived from bile. These sediments consist of cholesterol crystals, calcium salts, calcium bilirubinate, mucin, and other materials.

Signs and symptoms
Complications
Biliary sludge may cause complications such as biliary colic, acute cholecystitis, acute cholangitis, and acute pancreatitis.

Cause
Biliary sludge has been associated with pregnancy, rapid weight loss, total parenteral nutrition, drugs such as ceftriaxone and octreotide, solid organ transplantation, and gastric surgery. In many of these conditions, it is thought that the impairment in the contractility of the gallbladder leads to the formation of the sludge.

Pathophysiology
The pathophysiology of biliary sludge formation is likely related to gallbladder dysmotility
