%0 Review %T Consensus guidelines, Delphi methods, and evidence around anaesthetic technique for endoscopic retrograde cholangiopancreatography. %A Howell SJ %A Absalom AR %J Br J Anaesth %V 131 %N 4 %D 2023 10 %M 37718092 %F 11.719 %R 10.1016/j.bja.2023.07.001 %X Consensus guidelines on the anaesthetic management of endoscopic retrograde cholangiopancreatography (ERCP) have recently been published. The rigorous synthesis of expert opinion is invaluable when there are limited data, and these guidelines are a significant step forward. This review both guides practice and identifies important research questions. We challenge those working in this field to collaborate and produce the evidence for whether monitored anaesthesia care (MAC) is associated with a lower incidence of adverse events and better outcomes than general anaesthesia for ERCP.
