Core Tip
Core tip: Our initial motivation was to determine if there is a preferential endoscopic approach in choledocholithiasis, comparing efficacy and safety data between the two most widespread endoscopic methods, which is sphincterotomy with vs without large balloon dilation. Through the systematic review, it was possible to perform the meta-analysis of a large sample of patients obtained from properly conducted randomized clinical trials. We found that endoscopic sphincterotomy associated with large balloon dilation was a safer method compared to isolated sphincterotomy, since this last group carried an increased risk of post ERCP bleeding and required more frequent complementation with use of mechanical lithotripsy.
