title: Rational indications for sphincterotomy through intraoperative cholangiomanometry.
abstract: The loss of function of Oddi's sphincter due to sclerosis secondary to a lithiasic or alithiasic phlogosis, is the only rational indication for sphincterotomy. An operative test of the Oddi sphincter function is proposed, based on an original manometric procedure. This method, employed on 567 patients undergoing biliary surgery, allowed demonstration of a loss of function of Oddi's sphincter in 53 patients (9.4%), in whom a sphincterotomy was performed.
