Moderate Sedation or Deep Sedation for ERCP: What Are the Preferences in the Literature?

Abstract

One of the most essential procedures for individuals with biliopancreatic disorders is endoscopic retrograde cholangiopancreatography (ERCP). It is based on the combination of endoscopy and radiology to study the biliopancreatic ducts and apply therapeutic solutions. ERCP is currently used to treat choledocholithiasis with or without cholangitis, as well as pancreatic duct stones, benign bile, and pancreatic leaks. On the other hand, ERCP is an unpleasant procedure that must be conducted under anesthetic (moderate sedation, deep sedation, or general anesthesia). With procedures becoming more challenging, the role of anesthesia in ERCP has become even more relevant, and the use of general anesthesia has become better defined. In the last decades, many drugs have been used and some new drugs, like dexmedetomidine, have been recently introduced for sedation or anesthesia during ERCP. Moreover, the scientific community is still divided on the level of sedation to be applied, as well as on appropriate airway management. We therefore performed a narrative review of the literature to assess currently available anesthetic medications for elective ERCP and evidence supporting their effectiveness.
