[Percutaneous transhepatic cholangioscopy as a single-step technique]

Area of Science:

• Gastroenterology and Hepatology
• Interventional Endoscopy
• Surgical Techniques

Context:

• Patients with common bile duct diseases often require intervention.
• Transpapillary approaches are not suitable for all patients.
• Minimally invasive techniques are preferred to reduce patient morbidity.

Purpose:

• To describe a modified percutaneous transcholecystic approach (PTCS) for managing common bile duct (CBD) diseases.
• To present a technique that reduces treatment duration and minimizes patient injury.
• To highlight the versatility of PTCS for various diagnostic and therapeutic interventions.

Summary:

• The percutaneous transcholecystic approach (PTCS) is detailed for CBD diseases unsuitable for transpapillary methods.
• This technique facilitates lithotripsy of CBD stones, endoscopic biopsy, endoprosthesis management, and percutaneous papillotomy.
• The described method aims for shorter treatment times and reduced invasiveness.

Impact:

• Provides an alternative minimally invasive option for complex CBD cases.
• Potential to improve patient outcomes by reducing complications associated with traditional approaches.
• Expands the utility of percutaneous interventions in hepatobiliary disease management.
