Research progress on endoscopic sphincter of Oddi manometry / 中华肝胆外科杂志

ABSTRACT

Sphincter of Oddi manometry (SOM) is considered the gold standard for the diagnosis of sphincter of Oddi dysfunction (SOD),especially the type Ⅰ SOD.The dysfunction of sphincter of Oddi can lead to other comorbidity.Therefore,SOM is of special importance for such patients.When performing SOM,we need to intubate into the papilla,so it requires high technique and is associated with a relatively higher risk of post-ERCP pancreatitis.Recently,the equipment of SOM is being updated constantly.The use of modified catheter and high resolution gastrointestinal dynamic system for recording and analyzing has made the technology more accurate and safe than ever before.Due to the widespread use of ERCP,SOM is expected to be one of the routine examinations in clinical practice and its application has a promising prospect.This article reviews the latest research progress on SOM in recent years.
