Summary

Super fine cholangioscopy offers a safe and effective method for evaluating and treating biliary diseases like choledocholithiasis. This technique, utilizing a novel bended sheath, enhances visualization without requiring drainage tract dilation.

Area of Science:

  • Gastroenterology and Hepatology
  • Minimally Invasive Procedures

Background:

  • Percutaneous transhepatic cholangioscopy (PTCS) is valuable for biliary disease management but is invasive.
  • Existing cholangioscopes may have limitations in maneuverability and visualization.

Observation:

  • Two cases of post-surgical choledocholithiasis were treated using 5 F or 7 F super fine cholangioscopy.
  • A novel bended sheath was developed to overcome the angle system limitations of the cholangioscope.
  • Simultaneous saline injection via the sheath improved the cholangioscopic view.

Findings:

  • Super fine cholangioscopy enabled treatment of choledocholithiasis without drainage tract dilation.
  • The developed bended sheath significantly improved maneuverability and visualization during the procedure.

  • The technique proved safe and effective for both evaluation and treatment.

    • Implications:

    • This approach offers a less invasive option for biliary disease management.
    • The bended sheath technology could be applicable to other endoscopic procedures requiring enhanced angulation.
    • Further research may establish super fine cholangioscopy with bended sheaths as a standard tool for biliary interventions.
