| Stone extraction - balloon | |
 |
 |
| Stone extraction of small stones can occasionally be done by means of a balloon. The balloon is inflated proximal to the concrement and extracted from the bile duct will clear it and dislodge the stones to the duodenum. The left photograph shows an inflated balloon, the right one an extracted calculus. | |

Balloon in the common bile duct. The wall of both the ballon an the duct are closely adherent, thus stones distal to the balloon can be extracted. |
