title: Immediate and long term effects of instrumental dilation of the sphincter of Oddi.
abstract: Large dilators passed through the sphincter of Oddi do not prevent retained or recurrent common bile duct stones. Large dilators are more likely to cause postoperative pancreatitis than are small ones. Pancreatitis resulting from maximal dilation is more likely to be severe, and the patients are more likely to die from it.
