Biliary endoscopic sphincterotomy (EST) refers to the cutting of the biliary sphincter and intraduodenal segment of the common bile duct following selective cannulation, using a high frequency current applied with a special knife, sphincterotome, inserted into the papilla. EST is either used solely for the treatment of diseases of the papilla of Vater, such as sphincter of Oddi dysfunction or to facilitate subsequent therapeutic biliary interventions, such as stone extraction, stenting, etc. It is a prerequisite for biliary interventions, thus every practitioner who performs endoscopic retrograde cholangiopancreatography needs to know different techniques and the clinical and anatomic parameters related to the efficacy and safety of the procedure. In this manuscript, we will review the indications, contraindications and techniques of biliary EST and the management of its complications.
Core tip: Biliary endoscopic sphincterotomy (EST) is an essential procedure of the endoscopic retrograde cholangiopancreatography (ERCP) for the treatment and palliation of a wide spectrum of biliary and papillary diseases. It has some contraindications and complications. The physicians who interested in ERCP must learn the equipments, techniques and the management of the complications of biliary EST. We herein widely review the indications, contraindications and techniques of biliary EST and the management of its complications.
