Biliary microlithiasis

Biliary microlithiasis refers to the creation of small gallstones less than 3 mm in diameter in the biliary duct or gallbladder.

It has been suggested^[1] as a cause of postcholecystectomy syndrome, or PCS, the symptoms of which include:

• Upset stomach, nausea, and vomiting.
• Gas, bloating, and diarrhea.
• Persistent pain in the upper right abdomen.^[2]

Diagnostics

• Biliary Microlithiasis may be detectable by ultrasound using a Rapid Patient Rotation Ultrasound Protocol^[3]
• Analysis of biliary sludge obtained through endoscopic retrograde cholangiopancreatography (ERCP)

Treatment

• Oral ursodeoxycholic acid can be used to dissolve these crystals.^[1]
