ERCP: the unresolved question of endotracheal intubation.

The anesthesia community is still divided as to the appropriate airway management in patients undergoing endoscopic retrograde cholangiopancreatography. Increasingly, gastroenterologists are comfortable with deep sedation (normally propofol) without endotracheal intubation. There are no comprehensive reviews addressing the various pros and cons of an un-intubated airway management. It is hoped that the present review will benefit both anesthesia providers and gastroenterologists. The reasons to avoid routine endotracheal intubation and the approaches for an un-intubated anesthetic management are discussed. The special situations where endotracheal intubation is the preferred approach are mentioned. Many special techniques to manage airway are illustrated.
