Study Overview
Brief Summary
Although EPBD has a lower risk of post-ERCP bleeding and long-term complications than EST and is easier to perform in altered/difficult anatomy, EPBD is reserved for patients with bleeding diathesis by current consensus because some studies reported a higher risk of pancreatitis. However, recent meta-analyses indicate that short EPBD duration increases the risk of post-ERCP pancreatitis, and EPBD with adequate duration has a similar pancreatitis risk and a lower overall complication rate compared with EST for choledocholithiasis.
Therefore, this study aim to compare long-duration EPBD vs EST in the treatment of extrahepatic biliary stones.
Detailed Description
Gallstones occur in 10%-15% of adults in the United States and are the most common and costly digestive disorder. Concomitant bile duct stones occur in up to 15% of persons with symptomatic gallstones. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is the standard treatment for removal choledocholithiasis. The biliary sphincter is permanently ablated by sphincterotomy. Enteric-biliary reflux occurs with bacterial colonization, increased bile lithogenicity, contamination with cytotoxins, and chronic inflammation of the biliary system. Endoscopic papillary balloon dilation (EPBD) has become an option for removal of stones 1 cm or smaller in size. Advantages of EPBD over EST include a decreased risk of post-ERCP bleeding as well as a decreased risk of stone recurrence and cholangitis. Although a short dilation duration (≤1 minute) was previously advocated, a study that performed EPBD for 1 minute observed a 15.4% risk of post-ERCP pancreatitis with 2 cases of mortality. European Society of Gastrointestinal Endoscopy guideline recommends that the duration of EPBD should exceed 2 minutes because long-duration EPBD (>1 minute) is preferred over short-duration EPBD (≤1 minute) with better outcomes. A meta-analysis of RCTs showed that the duration of EPBD is inversely associated with the risk of PEP. Previous RCTs comparing outcome between EPBD and EST used short EPBD duration between 25 seconds and 1 minute, and there has been no comparison of outcome between EST and long-duration EPBD. The aim of this study was to compare the early and long term outcomes of patients treated with long duration balloon dilation or sphincterotomy for extraction of bile duct stones in a randomized, multicenter fashion involving a broad spectrum of practices.
