Core tip: Choledocholithiasis is frequently found in the adult population. Endoscopic sphincterotomy (ES) is considered the standard therapy for the treatment of this condition. However, several complications are associated with ES. Endoscopic balloon dilation (EBD) is actually recognized as an alternative to ES for the extraction of difficult bile duct stones. Reading the literature, we have found that most of the studies use small diameter balloons (6-10 mm), while the ones using larger balloons (from 12-20 mm) are rare. The aim of this retrospective study was to evaluate the efficacy and safety of large EBD performed for common bile duct difficult stones.
