- Papillary stenosis: A term historically used to describe a fixed narrowing of the sphincter.
Why are there so many names for this condition?
The variety of names for Sphincter of Oddi Dysfunction stems from its complex clinical presentation and the historical difficulty in diagnosing it before modern manometry techniques. In the past, doctors often grouped patients under general umbrellas like "post-cholecystectomy syndrome." Today, the medical community prefers the term Sphincter of Oddi Dysfunction, as it specifically identifies the functional or structural abnormality of the sphincter itself, allowing for more precise treatment protocols.
