چکیده
AIM To describe the efficacy and safety of endoscopic papillary large balloon dilatation (EPLBD) in the management of bile duct stones in a Western population. METHODS Data was collected from the endoscopic retrograde cholangiopancreatography (ERCP) and Radiology electronic database along with a review of case notes over a period of six years from 1st August 2009 to 31st July 2015 and incorporated into Microsoft excel. Statistical analyses were performed using MedCalc for Windows, version 12.5 (MedCalc Software, Ostend, Belgium). Simple statistical applications were applied in order to determine whether significant differences exist in comparison groups. We initially used simple proportions to describe the study populations. Furthermore, we used chi-square test to compare proportions and categorical variables. Non-parametric Mann-Whitney U-test was applied in order to compare continuous variables. All comparisons were deemed to be statistically significant if P values were less than 0.05. RESULTS EPLBD was performed in 229 patients (46 females) with mean age of 68 ± 14.3 years. 115/229 (50%) patients had failed duct clearance at previous ERCP referred from elsewhere with standard techniques. Duct clearance at the Index* ERCP (1st ERCP at our centre) was 72.5%. Final duct clearance rate was 98%. EPLBD after fresh sphincterotomy was performed in 81 (35.4%). Median balloon size was 13.5 mm (10 - 18). In addition to EPLBD, per-oral cholangioscopy (POC) and electrohydraulic lithotripsy (EHL) was performed in 35 (15%) patients at index* ERCP. 63 (27.5%) required repeat ERCP for stone clearance. 28 (44.5%) required POC and EHL and 11 (17.4%) had repeat EPLBD for complete duct clearance. Larger stone size (12.4 mm vs 17.4 mm, P < 0.000001), multiple stones (2, range (1-13) vs 3, range (1-12), P < 0.006) and dilated common bile duct (CBD) (12.4 mm vs 18.3 mm, P < 0.001) were significant predictors of failed duct clearance at index ERCP. 47 patients (20%) had ampullary or peri-ampullary diverticula. Procedure related adverse events included 2 cases of bleeding and pancreatitis (0.87%) each. CONCLUSION EPLBD is a safe and effective technique for CBDS removal. There is no difference in outcomes whether it is performed at the time of sphincterotomy or at a later procedure or whether there is a full or limited sphincterotomy.

Limited precut sphincterotomy combined with endoscopic papillary balloon dilation for common bile duct stone removal in patients with difficult biliary cannulation
BACKGROUND Difficult biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) can result in failure of common bile duct (CBD) stone removal and pancreatitis. The present study aimed to report the efficacy and safety of limited precut sphincterotomy (PS) combined with endoscopic papillary balloon dilation (EPBD) for CBD stone removal in patients with difficult biliary cannula...
متن کاملComplex biliary stones management: cholangioscopy versus papillary large balloon dilation – a randomized controlled trial
Background and study aims Endoscopic removal of biliary stones has high success rates, ranging between 85 % to 95 %. Nevertheless, some stones may be challenging and different endoscopic methods have evolved. Papillary large balloon dilation after sphincterotomy is a widely used technique with success rates ranging from 68 to 90 % for stones larger than 15 mm. Cholangioscopy allows performing ...

BACKGROUND/AIMS We evaluated the efficacy and cost-effectiveness of endoscopic papillary large balloon dilation (EPLBD) for large common bile duct (CBD) stone removal compared with endoscopic sphincterotomy (EST). METHODS A total of 1,580 patients who underwent endoscopic CBD stone extraction between January 2001 and July 2010 were reviewed. The following inclusion criteria were applied: chol...
متن کامل[Extraction of a big-sized common bile duct stone by means of biliary sphincterotomy followed by papillary dilatation with a hydrostatic balloon].
An 83-year-old woman was admitted because of colicky pain in the abdominal right upper quadrant and a cholestatic pattern in liver chemistry. Transcutaneous abdominal ultrasound showed a huge dilation of the extrahepatic bile duct. A distal common bile duct stone was also observed. An endoscopic retrograde cholangio-pancreatography (ERCP) was performed. Vater’s papilla was located in the right ...
متن کاملEndoscopic Papillary Balloon Dilation with Large Balloon after Limited Sphincterotomy for Retrieval of Choledocholithiasis
Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after li...
