Biliary microlithiasis refers to the creation of small gallstones less than 3mm 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:

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)
