About this study

Gallstone is a worldwide clinical problem which affecting most of the populations with incidence of 15 to 20% in west and 10% in Asians. About 5 to 15% of patient with gallstone will go on to develop bile duct calculi. There are several endoscopic strategies developed for treatment of common bile duct stone such as endoscopic sphincterotomy (EST), endoscopic papillary large balloon dilatation (EPLBD) and combination of EST plus EPLBD. Our aim of this study is to compare efficacy, and safety of EST alone group versus EST plus EPLBD group in removing CBD stone.

Read the detailed description

Endoscopic sphincterotomy (EST) is most widely used during endoscopic retrograde cholangiopancreatography (ERCP) to remove common bile duct (CBD) stone and considered as standard therapy for treatment of choledocholithiasis. However, in view of EST requires an adequate incision on major duodenal papilla to achieve biliary cannulation, it can potentially cause damage to biliary sphincter during the procedure and potentially increased risk of some complications such as bleeding and biliary reflux. This procedure carries risk of complications such as haemorrhage, perforation, and long-term effect like sphincter dysfunction.

Staritz introduced a method called endoscopic papillary large balloon dilatation (EPLBD) in 1983 as an alternative to EST in clearing CBD stone. EPLBD can reduced the risk of bleeding and perforation post procedure, but it carries higher risk of post-ERCP pancreatitis.

About 10 to 15% of CBD stone are unable to be extracted by both EST or EPLBD alone, especially in those patients with big and difficult stone (size bigger than 10 to 15mm, numerous, barrel-shaped, and impacted stones). Besides that, other factors that can contribute to failure of stone extraction are periampullary diverticulum or post operative variation, tortuosity and tightening of distal common bile duct.

In 2003, Ersoz introduced combination of EST plus EPLBD as an alternative method. It can reduce the risk of complications through avoiding a complete sphincterotomy, shortening procedural time, and reducing the need of usage of mechanical lithotripsy.

In a study on 2007, it showed that EST plus EPLBD had comparable efficacy and safety when compared to conventional EST alone and both groups have similar complication rate. Besides that, in a recent study in 2020, it also showed that EST plus EPLBD had a comparable efficacy when compared with EST alone in clearing CBD stone and EST plus EPLBD required shorter procedural time when compared with EST alone. There is no significant increased risk in pancreatitis for EST plus EPLBD. While, in a randomized controlled study in 2017, it showed that EST plus EPLBD is more effective than EST alone in clearing large CBD stone and is equally safe compared to EST alone. In another randomized controlled trial in 2013, the study showed that the success rate for complete CBD stone removal in first session is higher in EST plus EPLBD group when compared to EST alone and it is statistically significant. But the overall stone clearance rate and complication rate was similar in both groups. Apart from that, there are many other studies have suggested EST plus EPBD as a safe and promising alternative to conventional EST or EPLBD. In a published meta-analysis, accumulated data showed that EST plus EPLBD is a safe and effective procedure in removing large or difficult CBD stone without any additional risk of complications.

There is still no definite conclusion in evaluating superiority of EST plus EPLBD vs EST alone in term of efficacy in removing CBD stone.
