EPLBD With Limited EST vs. EPLBD for Choledocholithiasis

Endoscopic papillary balloon dilation (EPBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones (\> 10 mm), EPBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones, requiring additional mechanical lithotripsy (ML). The present study aims to compare the efficacy and safety of limited EST plus endoscopic papillary balloon dilation (EST-EPBD) with endoscopic papillary large balloon dilation for large choledocholithiasis.
