What this trial studies

This clinical trial aims to determine the effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) in treating idiopathic recurrent acute pancreatitis (IRAP) in adults. Participants will be randomly assigned to receive either ERCP, which includes pancreatic sphincterotomy and stent placement, or conservative treatment. The study will assess whether ERCP can reduce the frequency of pancreatitis episodes and help identify the underlying causes of IRAP. Participants will be monitored for one year to evaluate outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 who have experienced two or more episodes of acute pancreatitis with no identifiable cause after thorough clinical investigations.

Not a fit: Patients who have had prior sphincter interventions, are not fully recovered from a previous acute pancreatitis attack, or have contraindications to ERCP may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that significantly reduces the frequency of pancreatitis episodes in patients with idiopathic recurrent acute pancreatitis.

How similar studies have performed: While there is limited high-quality evidence on the use of ERCP for IRAP, previous smaller studies have shown promising results, indicating potential for success in this approach.

Inclusion Criteria:

1. Aged 18 to 70 years.
2. Patients diagnosed with IRAP:

3. At least 1 episode of AP one year prior to enrollment.
4. Consent to participate in the study and sign the informed consent form.

Exclusion Criteria:

1. Prior sphincter intervention.
2. Not recovered from prior AP attack.
3. Prior pancreatic surgery.
4. Contraindications to ERCP.
