Criteria used for technical and clinical success and failure of endoscopic therapy based on anatomic findings and presenting symptoms^*

	Complete Success	Failure
Technical Outcome
PD stricture	Successful dilation, with the stricture waist disappearing, and/or successful stent placement across stricture	Dilation is without appreciable effect, and/or a stent could not be placed across stricture
PD stone	Complete removal of intraductal stones with no stones remaining	Stone burden cannot be appreciably reduced
PD leak	Resolution of the leak on pancreatogram with no extravasation of contrast or recurrent fluid collection	Ongoing leak refractory to ET and/or requiring surgical treatment
CBD stricture	Successful dilation, with the stricture waist disappearing, and/or successful stent placement across stricture	Dilation is without appreciable effect, and/or stent could not be placed across stricture
Divisum	Successful stent placement in the dorsal duct and/or minor papillotomy	Inability to place a stent in the dorsal duct or perform a minor papillotomy
Papillary stenosis	Successful dilation, stent placement across the papilla, and/or pancreatic sphincterotomy	Inability to place a stent across the papilla or perform a pancreatic sphincterotomy
Clinical Outcome
Pain	Reduction in frequency of pain (not daily) and discontinuation of narcotic medications	No reduction in the frequency of pain and/or ongoing use of daily narcotics
RAP	No further episodes of acute pancreatitis following ET	No change in the frequency of episodes of RAP
Jaundice/cholestasis	Resolution of jaundice or cholestasis without need for PTC or surgery	No change in jaundice/cholestasis and/or need for PTC or surgery

^*Partial success was an intermediate category between complete success and failure
