Motor function of the opossum sphincter of Oddi.
We studied the opossum sphincter of Oddi (SO) because in this species the SO is approximately 3 cm in length and its extraduodenal location permits recording of motor activity with negligible interference from duodenal motor activity. The SO segment of 120 animals was evaluated by one or more of the following: (a) intraluminal manometry; (b) electromyography; (c) common bile duct (CBD) flow mon...
متن کاملSphincter of Oddi Dysfunction
INTRODUCTION Sphincter of Oddi dysfunction (SOD) is a benign acalculous obstruction to the flow of biliopancreatic secretions through the sphincter of Oddi (1,2). In the general population, its prevalence is 1.5% (3). It is one of the known causes of post-cholecystectomy syndrome, and is observed in 14%–23% of these patients (4,5). The post-cholecystectomy syndrome can loosely be defined as a p...

t The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidencebased methodology is used, performing a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (Food and Drug Administration Center for Devices and Radiological Health) database search to identify t...
متن کاملFunction and dysfunction of the sphincter of Oddi.
In this review, the function of the sphincter of Oddi (SO) is detailed in terms of normal motility, neural and hormonal control of SO function, coordination between gallbladder and SO motility, and correlation of motility of the SO and the duodenum. In addition, SO function tests, such as the morphine Prostigmin test (Nardi test), perfusion manometry, microtransducer manometry, and cholescintig...
متن کاملSphincter of Oddi Function and Risk Factors for Dysfunction
The sphincter of Oddi (SO) is a smooth muscle valve regulating the flow of biliary and pancreatic secretions into the duodenum, initially described in 1887 by the Italian anatomist, Ruggero Oddi. SO dysfunction (SOD) is a broad term referring to numerous biliary, pancreatic, and hepatic disorders resulting from spasms, strictures, and relaxation of this valve at inappropriate times. This review...
