Triple metallic stenting in hilar malignant biliary obstructions

Area of Science:

• Interventional Gastroenterology
• Hepatobiliary Surgery
• Oncology

Background:

• Malignant biliary obstruction presents a significant clinical challenge.
• Hilar biliary strictures, especially trifurcation anomalies, are complex to treat.
• Endoscopic and percutaneous stenting are common palliative measures.

Purpose of the Study:

• To evaluate the efficacy of triple metallic stenting in patients with high-level malignant biliary obstruction.
• To assess the impact of triple stenting on primary patency rates.
• To analyze changes in clinical and biochemical parameters post-intervention.

Main Methods:

• Retrospective analysis of eight patients with hilar malignant biliary obstruction treated with triple stenting.
• Percutaneous approach was predominantly used.
• Assessment of pre- and post-intervention bilirubin levels, pruritus, and cholangitis.
• Calculation of primary patency rates using the Kaplan-Meier method.

Main Results:

• Significant improvement in pruritus and cholangitis within 15 days.
• Marked reduction in serum bilirubin levels towards normal.
• Mean patency rate of 179 days.
• No procedure-related or 30-day mortality observed.

Conclusions:

• Triple metallic stenting offers rapid symptomatic relief in select malignant biliary obstruction cases.
• It may prevent cholangitis by avoiding stent isolation in complex anatomy.
• While not improving primary patency, it is a viable option for specific hilar trifurcation anomalies.
