Sleeve sphincter of Oddi (SO) manometry: a new method for characterizing the motility of the sphincter of Oddi

摘要

Perfused multilumen sphincter of Oddi (SO) manometry is accepted as the gold standard for diagnosis of SO dysfunction. However, this technique is associated with a relatively high incidence of post-procedure acute pancreatitis. In addition, triple-lumen manometry recordings may be difficult to interpret, as movement may produce artifacts. We have refined the development of a sleeve sensor for human SO manometry. This assembly aims to overcome the above limitations. In this study the accuracy of sleeve SO manometry (SOM) has been evaluated and compared with standard triple-lumen perfused SOM.
