Biliary Microlithiasis

We believe we detected Biliary Microlithiasis in the Gallbladder for the first time, using a simple unique Rapid Patient Rotation Ultrasound Protocol as part of a routine medical ultrasound.


Our objective is to attract medical research to validate this finding. Biliary microlithiasis is defined as particles aspirated at ERCP from the biliary system. Biliary microlithiasis must be distinguished from gallbladder microlithiasis defined as non shadowing gallbladder foci, < 2mm, seen on routine gallbladder ultrasound.


The Rapid Patient Rotation Ultrasound Technique visualizes dependent intraluminal gallbladder echogenic foci not previously recognized in the gallbladder. Intraluminal gallbladder echogenic is a term to describe foci approximately .5 to 2 mm in size seen free falling in gallbladder bile at the end of a rapid patient rotation. We consider these foci seen in the gallbladder lumen to be biliary microlithiasis. These foci are consistently detected in certain specific medical conditions of the gallbladder, pancreas and biliary system. Current literature suggests biliary microlithiasis is a cause for pancreatitis.


Dependent intraluminal gallbladder echogenic foci could obstruct in the cystic duct, pancreatic duct(s) and CBD ampulla.
