The Development and Evaluation of a Novel Duodenoscope Assessment Tool

Study Overview
=================
Brief Summary
-----------------
Endoscopic retrograde cholangiopancreatography (ERCP) procedures are performed using duodenoscopes for the treatment of pancreatic and biliary diseases. Although outcomes in endoscopic retrograde cholangiopancreatography (ERCP) procedures are measured mainly in terms of procedural success and complications, currently there are no objective tools to assess the technical performance of the duodenoscopes. The Center for Interventional Endoscopy has maintained a multicenter database that prospectively evaluates the technical performance of duodenoscopes for performing ERCPs. Our objective is to analyze the database in order to summarize the technical performance of duodenoscopes during ERCPs and evaluate the reliability of the duodenoscope assessment tool.

Detailed Description
-----------------
Outcomes in ERCP are measured mainly in terms of procedural success and complications. Recently, disposable duodenoscopes have been developed to overcome the challenges associated with reusable duodenoscope-related infections. While it is important to measure the technical performance of the newly developed disposable duodenoscope relative to conventional reusable scopes, presently, there are no objective tools to accomplish this task. The aim of this registry is to assess the reliability of a newly designed assessment tool to evaluate the technical performance of the currently available duodenoscopes. The duodenoscope assessment tool will be completed by each endoscopist after performing the ERCP and this data will be summarized and analyzed to assess the technical performance of the duodenoscopes and also to assess validity of the duodenoscope assessment tool. This is a multicenter study, with data collection from multiple centers across the United States.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Endoscopic retrograde cholangiopancreatography (ERCP)<br>At the time of each ERCP procedure, information on procedure indication, technical performance of the duodenoscope and adverse events will be collected using a newly designed duodenoscope assessment tool. The duodenoscope assessment tool was developed to measure the technical performance of the duodenoscopes based on three components: passage and positioning at the papilla, performing requisite technical maneuvers and technical features. Each performance component is graded on a scale ranging from 1 to 5 (1 for easy maneuverability, 5 for most difficult maneuverability). Duodenoscope assessment tool also captures data on procedural indications, cannulation success rates and adverse events. | Procedure: Endoscopic retrograde cholangiopancreatography (ERCP)<br>* At the time of each ERCP procedure, information on procedure indication, technical performance of the duodenoscope and adverse events will be collected using a newly designed duodenoscope assessment tool.
