Advances in Risk Factors for Recurrence of Common Bile Duct Stones

Choledocholithiasis is a chronic common disease.The incidence of cholelithiasis is 5%-15%, of which 5%-30% are combined with Choledocholithiasis.Although endoscopic cholangiopancreatography (ERCP) + endoscopic sphincterotomy (EST) is the most common treatment procedure, which clearance rate is up to 95%, the incidence of recurrent choledocholithiasis was 4%-25%.The risk factors of recurrence after choledocholithiasis clearance are the focuses of current researches, which are caused by multiple factors.We first systematically summarize the risk factors of common bile duct stones (CBDS) recurrence into five aspects: first-episode stone related factors, congenital factors, biological factors, behavioral intervention factors, and the numbers of stone recurrence.
