Overview
Electrohydraulic lithotripsy (EHL) is the latest advancement in the removal of gallstones in a nonsurgical manner. EHL reportedly has success rates of over 90%.
Future or Investigational Therapies
- Electrohydraulic lithotripsy (EHL) works on the same principle as ERCP.[1][2][3]
- A digital single-operator cholangioscope known as "SpyGlass" is passed through a duodenoscope, which is passed through the oral passage.
- Unlike ERCP, no X-rays are needed to visualize the stones.
- Once the stones are reached, a powerful burst of electrical currents are released to shatter stones.
- The main complicaton with EHL is that the common bile duct may be perforated.
- Bleeding may also occur, as well as injury to the surrounding epithelium.
