aScope Single Use ERCP Study- ASSURE Study
United Kingdom59 participantsStarted 2022-07-05
Plain-language summary
Patients undergo ERCP procedure (Endoscopic procedure with the help of x-rays) for a variety of reasons such as common bile duct (CBD)stones, bile duct obstruction secondary to bile duct narrowing (Strictures) and for bile leak. The incidence of infection post-ERCP is around one in 200. There are some group of patients where this risk is significantly increased. In this high risk group, the risk increases from 1 in 75 to in some diseases 1 in 15 (Described in PIS). There are some reports that some of the infection may be contributed by contamination of bacteria in the scope. This happens even after diligently sterilizing the scope. A multi-centre study reported that the risk of contamination is as high as 39% but what we do not know is how many resulted in bacterial infection. The investigators do not know what percentage of infection is secondary to the above. The new single use duodenoscope (aScope, Ambu Ltd) has been introduced in to the market to minimise the risk of post ERCP infection. It is CE marked but the evidence for performance of the aScope is limited. The investigators want to assess the performance of the scope simultaneously in multiple different hospitals. In addition, the investigators also want to assess the cost consequence to the NHS for using the above scope. Hence, the investigators want to assess the performance of the scope in the high risk groups for infection.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
