Carbon dioxide insufflation during ERCP for reduction of postprocedure pain
Published 2009“…Background: Abdominal pain after ERCP is common, and although it is frequently nonspecific and self-limited, it may provoke concern for complications and thus distress both patients and physicians. Carbon dioxide (CO2) insufflation during ERCP may reduce abdominal distension in comparison to insufflation of air, resulting in less pain. …”
