Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 or older diagnosed with chronic pancreatitis and experiencing symptomatic biliary stricture.

Probably not a fit

Patients with prior plastic stenting exceeding six months, any metal stenting, or biliary stricture of malignant etiology may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the effectiveness and safety of a single plastic stent versus a fully covered self-expanding metal stent in treating benign biliary stricture caused by chronic pancreatitis. Participants will be randomly assigned to receive one of the two stent types, with treatment lasting for six months and follow-up extending to 18 months. The study focuses on whether the single plastic stent can provide similar benefits as the metal stent while potentially being more cost-effective and having fewer complications. The trial is designed as a prospective, open-label, randomized controlled, non-inferiority trial.

Why it matters

Potential benefit: If successful, this study could provide a more effective and cost-efficient treatment option for patients with benign biliary stricture due to chronic pancreatitis.

How similar studies have gone: Previous studies have indicated limitations in the effectiveness of single plastic stents, but this trial's approach of managing chronic pancreatitis effectively before stent placement is novel and may yield different results.
