Summary

Choledochoscopy is a safe and effective technique for evaluating and treating biliary diseases, reducing the need for radiation exposure. This minimally invasive procedure is well-tolerated by patients, with a low complication rate.

Area of Science:

  • Gastroenterology and Hepatology
  • Interventional Radiology

Background:

  • Percutaneous biliary procedures are essential for diagnosing and managing biliary tract diseases.
  • Choledochoscopy offers direct visualization within the biliary ducts, potentially improving diagnostic accuracy and therapeutic outcomes.

Purpose of the Study:

  • To evaluate the safety, efficacy, and outcomes of choledochoscopy as an adjunctive technique in percutaneous biliary procedures.
  • To assess the range of indications and complication rates associated with choledochoscopy.

Main Methods:

  • Twenty-two patients underwent 24 percutaneous biliary procedures utilizing choledochoscopy.
  • Procedures were performed through established or new percutaneous tracts for indications including calculi removal, biopsies, and anastomosis evaluation.
  • Intravenous antibiotics were administered pre- and post-procedure.

Main Results:

  • All procedures were technically successful, with one exception due to an undersized tract.
  • The sole complication was severe nausea in one patient, requiring hospitalization.
  • Indications included calculi removal (n=15), biopsies (n=8), and anastomosis evaluation (n=11).

Conclusions:

  • Choledochoscopy is a safe, atraumatic, and well-tolerated method for evaluating and treating biliary diseases.
  • This technique significantly reduces radiation exposure.
  • It is a rapid procedure requiring minimal sedation, suitable for both inpatient and outpatient settings.
