About this study

Official title: A Prospective Randomized Trial Comparing EUS Guided ERCP Without Fluoroscopy With Standard ERCP in Common Bile Duct Stone Removal

For endoscopist, ERCP for bile duct stone removal is the most widely performed procedure. However, the risk associated radiation exposure to patients and staff are not neglible. Earlier studies, ERCP without the use of fluoroscopy has been reported high success for bile duct stone removal in pregnant patients to prevent radiation exposure to the fetus. EUS is highy accurate technique in detecting common bile duct stone and guiding for therapeutic intervention. There has been a few data from literature showed that EUS guided CBD stone ( CBDS ) removal are equivalent to those following ERCP in term of successful CBDS removal and complications. This randomized trial is designed to address the question that EUS guided CBDS removal is equivalent to ERCP in term of efficacy and safety.

Read the detailed description

Common bile duct stones (CBDS) can be complicated with various conditions including biliary pain, acute cholangitis, acute pancreatitis and secondary biliary cirrhosis. CBDS should therefore be removed even if patients are asymptomatic.

Endoscopic retrograde cholangiopancreatography (ERCP) is the cornerstone treatment of CBDS. ERCP is often performed under fluoroscopic guidance. This comprises biliary cannulation whereby the bile duct is achieved with a standard ERCP catheter under fluoroscopy guidance, radiocontrast was injected for confirmation and images of biliary system, location and number of CBDS, biliary sphincterotomy was then performed followed by stone extraction using a standard accessories such as a basket and or balloon. Therefore, the endoscopist, endoscopic staff and patient are potentially exposed to ionizing radiation during ERCP. Endoscopists should always attempt to minimize radiation exposure to the personnel staffs and patients by following the ALARA principle ("As Low As Reasonably Achievable"). ERCP without the use of fluoroscopy is the one method to avoid exposure to radiation. A few retrospective case series have been shown that ERCP can be performed with high success rate without the need for fluoroscopic imaging.

EUS has been proven to have diagnostic accuracy comparable to ERCP in the diagnosis of CBDS, and it's associated with a very low procedure related complications and non-radiation exposure procedure. With EUS performed before ERCP, unnecessary ERCP and its related complications can be avoided in patients without CBDS. In patients with CBDS, the images of pancreaticobiliary tract derived from EUS provide an information regarding the location, size and number of CBDS for guiding therapeutic endoscopy, and allowing a therapeutic ERCP in the same session of sedation. Vohra et al. reported the retrospective case series of EUS - based ERCP in 10 pregnant patients, they have shown that EUS performed prior ERCP can eliminate unnecessary ERCP and achieve in CBDS clearance without the use of fluoroscopy. We have previously reported the use of EUS guided ERCP in the removal of CBDS without fluoroscopy (EGWF) in the pilot study, it showed that EGWF was feasible in selected patients with CBDS. The efficacy of EUS guided ERCP in CBDS removal without fluoroscopy compared with standard ERCP has not been fully assessed. We therefore prospectively investigated the efficacy and safety of EGWF versus ERCP in CBDS removal in a larger patient cohort.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ERCP without the use of fluoroscopyProcedure or surgery

    ERCP removal of stone technique without the use of fluoroscopy involves: (1) catheter with wire achieve bile duct, (2) confirmation of bile duct achievement with catheter aspiration of bile, (3) performance of endoscopic biliary sphinctertome, (4) stone removal with balloon or basket- number of stones removed should compare number detected on EUS, (5) confirmation of complete stone clearance with radiocontrast.

  • ERCP with the use of fluoroscopyProcedure or surgery

    ERCP removal of stone technique with the use of fluoroscopy involves: (1) catheter with wire achieve bile duct, (2) confirmation of bile duct achievement with fluoroscopy images, (3) performance of endoscopic biliary sphinctertome, (4) stone removal with balloon or basket, (5) confirmation of complete stone clearance with radiocontrast.

Questions about this trial

What is this clinical trial studying?

A study testing ERCP without the use of fluoroscopy and ERCP with the use of fluoroscopy in people with Choledocholithiasis, run by Prince of Songkla University at 1 site in Thailand.
