Abstract
|
|
|
Unexplained chronic and recurrent biliary type abdominal pain, with or without prior history of cholecystectomy, in the absence of structural changes in pancreatobiliary anatomy is often attributed to an abnormal pressure profile of the sphincter
of
Oddi. This symptom complex is often attributed to the syndrome of sphincter of Oddi dysfunction. The diagnosis of this disorder has been suggested by the symptom compex, exclusion of anatomic biliary tract disease dilatation of common bile ducts
or
delayed drainage of contrast media from the bile ducts during the endoscopic retrograde cholangiography. But, more recently developed technique, endoscopic manometry of the sphincter of Oddi, appears to be most sensitive for detecting increases
in
biliary sphincter pressures. Even in the presence of nondilated bile ducts. This syndrome may be further subdivided into sphincter of Oddi stenosis that indicates a structual narrowing of the sphincter of Oddi and sphincter of Oddi dyskinesia
that
is
defined as abnormal sphincter of Oddi motor activity. The basal pressure, which is elevated in both stenosis and dyskinesia of the sphincter of Oddi, is the msot widely agreedupon abnormality. Administration of smooth muscle relaxants may help to
distinguish between the two enities ; these agents do not have any effect on a fixed stenosis but may inhibit the elevated sphincter tone in dyskinesia. We report a case of the sphincter of oddi stenosis diagnosed by biliary manometry(Korean J
gastreoenterol 1994 ; 26 : 200-205)
