What this trial studies

This study aims to compare the effectiveness and safety of two types of duodenoscopes used during Endoscopic retrograde cholangiopancreatography (ERCP) procedures: one with a single-use distal cover and a conventional reusable version. Patients eligible for the study will be randomly assigned to receive one of the two duodenoscopes during their ERCP. The study will monitor procedure success rates and complication rates, with follow-up assessments conducted at one week, one month, and three months post-procedure to gather data on any adverse events. The goal is to determine if the single-use duodenoscope offers any advantages over the conventional type.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are undergoing ERCP for biliary or pancreatic conditions.

Not a fit: Patients who are pregnant, unable to consent, or have specific infections or surgically altered anatomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved safety and effectiveness in ERCP procedures for patients with biliary and pancreatic diseases.

How similar studies have performed: Other studies have explored the use of single-use endoscopes, showing promising results, but this specific comparison is novel.
