Oddi sphincter is an important valve controlling the biliopancreatic duct passage, and its injury can cause enterobiliary reflux, resulting in a series of long-term complications such as reflux cholangitis, cholecystitis, recurrence of calculi, and even cholangiocarcinoma. As one of the most common diseases of digestive system, choledocholithiasis is increasing year by year in recent years. Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred minimally invasive method for the treatment of choledocholithiasis and has been widely used in clinical practice. But different ERCP procedures may damage Oddi sphincter. This article reviews the effects of ERCPs (endoscopic sphincterotomy, endoscopic papillary balloon dilation, endoscopic sphincterotomy plus balloon dilation, endoscopic endoclip papilloplasty) on Oddi sphincter and their respective advantages and disadvantages and application prospect.
