Summary
This study introduces a novel endoscopic ultrasonography (EUS)-guided technique for draining both sides of the bile ducts in patients with hilar obstruction, offering a new option when other methods fail.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Biliary Interventions
Background:
- Biliary obstruction management often involves ERCP.
- EUS-guided hepaticogastrostomy is an alternative but limited to left-side drainage.
- Hilar obstruction presents unique challenges for biliary drainage.
Purpose of the Study:
- To describe a novel EUS-guided hepaticogastrostomy technique for draining both right and left hepatic ducts.
- To evaluate the feasibility and safety of this new method in patients with hilar obstruction.
Main Methods:
- A three-step EUS-guided procedure was performed in nine patients with hilar obstruction.
- Involved transgastric puncture, guidewire placement across the bifurcation, and dual stent placement.
- A non-covered metal stent connected right and left ducts, followed by a partially covered stent in the left duct.
Main Results:
- Successful biliary drainage was achieved in seven out of nine patients.
- Six patients experienced reduced jaundice, enabling chemotherapy initiation.
- One patient had drainage failure, and another developed sepsis and died.
Conclusions:
- This pilot study demonstrates the feasibility of a new EUS-guided technique for bilateral hepatic duct drainage in hilar obstruction.
- The method shows potential for managing complex biliary obstructions with a low rate of major complications.
