Consenting eligible patients will sign an IRB (Institutional Review Board)-approved, written informed consent to verify their willingness to participate in this study. Informed consent will be obtained on the day of their scheduled endoscopic drainage procedure and will occur at the time of consent to undergo the endoscopic drainage procedure (standard of care). Consent for the study will be obtained by one of the participating endoscopists and/or a research assistant. Subjects will receive a copy of the signed and dated informed consent document. Original informed consent documents will be maintained on-file at each participating center and will be made available for review upon request by coordinating center team or IRB, and/or any additional oversight organizations. A note may be made in the subject's hospital chart regarding participation in the research study. Once consented and enrolled into the trial, subjects will be issued a unique code to be used on data collection forms and other research records throughout the duration of the trial.
