Risk factors identified on multivariate analysis:
(1) minor papilla sphincterotomy
(2) sphincter of Oddi dysfunction suspected
(3) history of a previous episode of ERCP-related pancreatitis
(4) age < 60 years of age
(5) >= 2 contrast injections into the pancreatic duct
(6) a trainee involved in the procedure
where:
• The odds ratio were 3.8 for sphincterotomy, 2.6 for suspected sphincter of Oddi dysfunction, and 1.5 to 2.0 for the remainder of factors.
In an attempt to develop a risk score, I assigned points as follows:
