Sin embargo, su aplicación en la práctica diaria en las unidades de endoscopia es poco frecuente. Las modificaciones que se han realizado en los últimos años al colangioscopio brindan una mejoría muy importante en su operatividad, y en combinación con la fibra óptica, han permitido el tratamiento de litos de difícil manejo, tanto de la vía biliar como del conducto pancreático principal. Descripción del primer caso tratado mediante colangioscopia con SpyGlass DS (Boston Scientific) y litotripsia con láser en México. Resolución de la coledocolitiasis sin complicaciones. Las mejoras efectuadas a este endoscopio permiten una funcionalidad superior. La aplicación de esta tecnología brinda una nueva herramienta terapéutica en la resolución de los litos de difícil manejo con seguridad, como mostramos en este caso.]]></p></abstract>

However, its application in the daily practice in endoscopy units is rare. The modifications made in recent years to the cholangioscope provide a very important improvement in its operation, and in combination with fiber optics, have allowed the treatment of difficult-to-handle lithos, both in the bile duct and the main pancreatic duct. Description of the first case treated by cholangioscopy with SpyGlass DS (Boston Scientific) and laser lithotripsy in Mexico. Resolution of choledocholithiasis without complications. The improvements made to this endoscope allow for better functionality.
