Even experienced endoscopists have 90% success in achieving deep biliary cannulation with standard methods. Biliary cannulation may become difficult in 10%-15% of patients with biliary obstruction and precut (access) sphincterotomy is frequently chosen as a rescue treatment in these cases. Generally, precut sphincterotomy ensures a rate of 90%-100% successful deep biliary cannulation. The precut technique has been performed as either a fistulotomy with a needle knife sphincterotome or as a transpapillary septotomy with a standard sphincterotome. Both methods have similar efficacy and complication rates when administered to the prope . . .r patient. Although precut sphincterotomy ensures over 90% success of biliary cannulation, it has been characterized as an independent risk factor for pancreatitis. The complications of the precut technique are not limited to pancreatitis. Two more important ones, bleeding and perforation, are also reported in some publications as being observed more commonly than during standard sphincterotomy. It is also reported that precut sphincterotomy increases morbidity when performed in patients without dilatation of their biliary tract. Nevertheless, precut sphincterotomy is a good alternative as a rescue method in the setting of a failed standard cannulation method. This paper discusses the technical details, timing, efficacy and potential complications of precut sphincterotomy. (C) 2013 Baishideng. All rights reserved Daha fazlası Daha az
