Bile duct stones can form even after removal of the gallbladder.
In this series of pictures, the process of removal of the stones from the bile duct is seen.
A cutting device with green markings is inserted in bile duct.
A cut is placed using cautery, or an electric current that generates heat. The burnt area appears white.
The opening of the bile duct is enlarged.
A white catheter with a balloon is inserted above the stones (Ballon is not seen here).
The balloon is inflated and is pulled.
The stones are dragged out of the bile duct.
Bile duct stones can form even after removal of the gall bladder.
In this series of pictures, different stones which have come out are seen.
They are dark brown and greenish brown.
Relatively large stones (>1cm) are seen to have come out.
