Stenting as a definitive procedure in benign biliary disease

Area of Science:

• Gastroenterology
• Hepatobiliary Medicine
• Interventional Endoscopy

Background:

• Benign biliary disease management often involves endoscopic retrograde cholangiopancreatography (ERCP).
• Biliary stent insertion is a therapeutic option for specific benign biliary conditions.

Purpose of the Study:

• To evaluate the effectiveness and safety of biliary stent insertion for benign biliary diseases.
• To compare outcomes between stenting for unextractable stones versus biliary strictures.

Main Methods:

• Retrospective analysis of 31 patients undergoing ERCP with biliary stent insertion over five years.
• Data collected via chart review, physician contact, and death certificate checks.
• Outcomes measured included complications, stent-related death, serum bilirubin, and alkaline phosphatase levels.

Main Results:

• 32% of patients died within a mean of 12 months; one death was biliary-related.
• 21 patients were followed for a mean of 29 months and remained asymptomatic.
• Complications occurred in 6 patients, predominantly those with pre-existing strictures (5/6).
• Further procedures were significantly more frequent in stricture patients (45% vs. 5%, p < 0.05).
• Elevated alkaline phosphatase levels were noted in stricture patients (512 vs. 176, p < 0.005).

Conclusions:

• Biliary stenting for unextractable stones in non-surgical candidates is safe and effective.
• Stenting in the presence of biliary strictures is associated with a significantly higher risk of complications.
• Careful patient selection is crucial, especially when strictures are present.
