This is a preview. You can go through the whole questionnaire to see how it works, but nothing you enter is saved. It's here so the panel can look over the questions before the formal study begins.

Purpose of the study

Post-ERCP pancreatitis (PEP) is the most frequent and clinically significant complication of endoscopic retrograde cholangiopancreatography. Despite extensive investigation, its definition, the stratification of patient- and procedure-related risk, and the design of preventive trials remain inconsistent across the literature, limiting comparison between studies and cumulative progress. This international Delphi study convenes experts in pancreaticobiliary endoscopy to develop consensus recommendations that standardize how PEP is defined and risk-stratified, and that establish priorities for the design of future clinical trials. Across successive, anonymized rounds, panelists rate a structured set of statements and reconsider their positions in light of the panel's aggregated responses until consensus is reached.

What participation involves

You’ll complete an online questionnaire on PEP definitions, risk factors, and research priorities — about 20–30 minutes. You can revise your answers while a round is open; after each round closes, the panel receives an anonymized summary of the group’s responses before the next round.

Confidentiality

All responses are anonymized. Fellow panelists cannot identify your answers, and published results present only aggregate data. Your participation status is never disclosed to other panelists.

Voluntary participation

Participation is entirely voluntary; you may withdraw at any time without consequence. There is no compensation associated with this study.
