Abstract:
We performed ERCP manometry of Sphincter of Oddi(SO) before and after endoscopic sphincterotomy(EST) for evaluation of the effect af EST on the SO. The subjects were postcholecystectomized common bile duct stone patients(n=l2) and EST was performed by major incision. The pressure gradient between common bile duct and duodenum before EST (8.6 + 3.9 mmHg) decreased significantly after EST(2.4 +1.7 mmHg). The length of SO before EST(8.8 + 0.8mmHg) decreased significantly after EST(2.5 + 0.8mm). But in each patient, the pressure gradient between common bile duct and duodenum remained in spite of the major incision. In conclusion, EST alters the function of the sphincter of the Oddi, but does not destroy its all protective function. The positive pressure in the bile duct is preserved in contrast to the absolute loss of pressure following surgical transduodenal sphincteroplasty.
