Abstract    The sphincter of Oddi is a neuromuscular structure located at the junction of the bile and pancreatic ducts with the duodenum. The primary functions of the sphincter of Oddi are to regulate the delivery of bile and pancreatic juice into the duodenum and to prevent the reflux of duodenal contents restrograde infection. EST damage the integrity of the Oddi sphincter, leading to sphincter relaxation or stenosis, causing partial or complete loss of the original physiological function of the Oddi sphincter. Therefore, surgeons should strictly control the indications of EST, retain the sphincter function as far as possible, so as to provide patients with more reasonable and standardized treatment strategy.

Key words: sphincter of Oddi, endoscopic sphincterotomy, endoscopic retrograde cholangiopancreatography
