Summary
Combined endoscopic and percutaneous biliary procedures significantly improve success rates when standard endoscopic methods fail due to difficult anatomy or strictures. This approach offers a high success rate with manageable complications.
Area of Science:
- Gastroenterology
- Interventional Radiology
Background:
- Endoscopic biliary procedures have high success rates (89-97%) but can fail due to challenging anatomy or strictures.
- Common failure points include papilla of Vater cannulation difficulty and inability to traverse rigid biliary strictures.
Purpose of the Study:
- To evaluate the efficacy of combined percutaneous and endoscopic biliary procedures in cases of failed standard endoscopic interventions.
- To assess the success rate and complication profile of this combined approach.
Main Methods:
- A combined approach involving percutaneous antegrade catheter or guidewire placement into the duodenum was utilized.
- This technique was applied in 44 procedures on 42 patients experiencing difficulties with standard endoscopic biliary interventions.
Main Results:
- The combined procedure achieved a high success rate of 98% (43 out of 44 procedures).
- Complications included two severe and eight mild events, indicating a manageable safety profile.
Conclusions:
- Combined percutaneous and endoscopic biliary procedures effectively overcome challenges posed by tortuous ducts and rigid strictures.
- This technique obviates the need for more invasive percutaneous interventions and transhepatic tract dilatation, enhancing patient outcomes.
