Single Use ERCP -SURE Study
Single Use ERCP -SURE Study
We do ERCP procedure (Endoscopic procedure with the help of x-rays) for a variety of reasons
 such as bile duct 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. We do not know what percentage of
 infection is secondary to the above. The new single use duodenoscope has been introduced in
 to the market to minimise the risk of post ERCP infection. It is CE marked and a single
 centre study reported that the above performance of the above scope was comparable to the
 standard reusable scope. We want to assess the scope simultaneously in multiple different
 hospitals. In addition, we also want to assess the cost consequence to the NHS for using the
 above scope. Hence we want to assess the performance of the scope in the high risk groups for
 infection.
ERCP is a therapeutic endoscopic procedure done to establish either bile duct or pancreatic
 duct drainage or both. The indications for ERCP are bile duct stones, bile duct strictures,
 sphincter of Oddi manometry with sphincterotomy, bile leak, pancreatic duct stones and
 pancreatic duct stricture. The intended benefits of the procedure are either to relieve bile
 duct/ pancreatic duct obstruction or facilitate bile duct/ pancreatic duct drainage. It is a
 minimally invasive procedure and is associated with reduced morbidity compared to surgery.

 Gall stones are made of cholesterol, pigment and mixture of cholesterol and pigment. The
 incidence of stones with in the bile-duct varies from 4.6% to 19%.The stones are
 predominantly formed in the gall bladder and are displaced from the gall bladder in to the
 bile duct via the cystic duct. ERCP is an effective and minimally invasive treatment for bile
 duct stones. Treatment of extra- hepatic biliary strictures; irrespective of their aetiology,
 is to place a stent across the stricture through ERCP and facilitate biliary drainage.

 There is emerging data that the incidence of carbapenem resistant enterobacteriae,
 Multidrug-resistant Klebsiella pneumoniae, and New Delhi metallo-β-lactamase-producing
 carbapenem-resistant Escherichia coli (CRE) following exposure to contaminated duodenoscopes
 (ERCP endoscopes). The main reason for the outbreaks is due to inadequate reprocessing
 (Cleaning of endoscope post procedure) leading to contamination of endoscpes.

 To minimise the risk of contamination and outbreak of above infections, single use disposable
 duodenoscopes have been brought in to the market. The aim of the study is to assess the
 performance of the single use duodenoscope against the standard reusable duodenoscope and the
 cost consequences associated with the above.
