Solid state biliary manometry catheter: impact on diagnosis and post-study pancreatitis.
Perfusion manometry of the sphincter of Oddi has been the standard for the investigation of patients with presumed sphincter of Oddi dysfunction (SOD). Microtransducer manometry (MTM) of the sphincter of Oddi represents an alternative to perfusion manometry. The technical success and reproducibility of MTM are as good as for perfusion manometry. Current data suggest that the upper limit for normal of basal sphincter of Oddi pressures measured with MTM lies at approximately 35 mm Hg. Pancreatitis risk after MTM in patients with SOD compares favorably with that after perfusion manometry. Low cost and ease of handling make MTM of the sphincter of Oddi an attractive alternative.
