Is this trial a fit for you?

What this trial studies

This is a multicenter prospective observational registry collecting data from routine clinical care. It documents patient characteristics, imaging, treatments, adverse events, recurrence, and outcomes for adults with local complications of acute pancreatitis or postoperative pancreatic fistula. Treatment decisions are made by treating physicians, not by the study protocol. The primary goal is to describe clinical success within 180 days, with secondary aims including technical success, adverse events, additional interventions, mortality, and healthcare use. Exploratory analyses will explore factors associated with outcomes without assigning any diagnostic or therapeutic interventions.

Why it matters

Potential benefit: If successful, the registry could clarify which management approaches are common and what outcomes look like across institutions.

How similar studies have gone: Prior work with similar observational registries in pancreatology suggest feasibility and can reveal real-world patterns, though direct benefit is not guaranteed by the registry.
