The aim of the Calgary Registry for Advanced and Therapeutic Endoscopy (CReATE) is to be a high-fidelity prospective multi-centre registry. The study population consists of consecutive adult ERCP patients from September 2018 to August 2022. Informed consent is acquired for each patient. All relevant pre-procedural, procedural, peri-procedural and post-procedural data are captured in real time by a full-time third-party research assistant directly observing procedures. Outcomes are ascertained by comprehensive medical record review and patient phone interview 30 days after the index procedure. This registry also serves as a secure data collection platform for several currently recruiting prospective studies and randomized trials.

Inclusion Criteria:

• any standard indication for ERCP, in the absence of standard contraindications;
• age 18 years or over;
• ability and willingness to give informed consent to be included in the registry and/or to involvement in one (or more) prospective sub-studies, or accompaniment by a surrogate who is willing and able to provide consent.

Exclusion Criteria:

-none other than inverses of above.

Adult patients undergoing ERCP.

Future studies will utilize patient-specific data, which will be in a de-identified encrypted secure format whenever shared.

For 5 years after data collection is complete.
