Balloon Dilation of the Sphincter of Oddi
17 March 2008 (online)
No controlled studies document either clinical or biochemical efficacy following balloon dilation of the sphincter of Oddi. Because of this and the unacceptable rates of pancreatitis and cholangitis associated with sphincter dilation when compared with the other available modalities of sphincterotomy, stent placement and surgery, this technology currently has little place when dealing with a spastic or stenotic sphincter mechanism.
